128 LIPARA BOMBYCOIDES. 



most of the American Lepi(lo|>ti-iists consider it a synonym, I have deRif;nated on page 117 of this volume lafter the description of 

 Sph. Ilarrim). The present H<riire on accompanying plate XIV' was carefully made from Prof Westwood's drawing, above alluded to. 

 Although llic type was taken in Caiuida, nolhing of the kind is known to exist in any American colleclion ; it ap|iroaches nearest 

 to Sph. Harrisii, but the latter, which I have figured on plate XIII, f. 10, though having much the same general appearance yet difl'ers 

 considerably in detail, though Jinmhyroides may possibly be an aberration of it. That ii is however a distinct species that is yet to be 

 re-discovered is after all not unlikely when we consider that such a conspicuous species as S. Plata escaped the notice of the many 

 American collectors and students until three years since when 1 detected it in a small collei^tion sent me from Montreal, Canada. If I 

 have been able to do little towards elucidating the mystery that enshrouds Bombyroides, I at least trust I have not done an unacceptable 

 act in presenting the figure of Walker's type that my friends and the others may have .some better knowledge of it.s appearance. 



SAM I A GLOVER I. Streck. 



Since figuring and <lescribing this species in the commencement of this work I have received through Mr. Xeumoegen a number 

 of cocoons from I'tali an<l Arizona which developed in due time the perfect insect. 1( is subject to the same variations as Cecropia in 

 size of discal lime, breadth of white transverse hands, etc., etc.; also varying considerably in size, the largest being six inches in ex- 

 panse, the smallest hut four. Some examples are much jialer tlian others in the red ground colour Of the larva I have as yet re- 

 ceived no description, and have only learned that it is found on gooseberry and currant; but the cocoons are somewhat of the shape of 

 those of S. Cecrnpia though not so large and imlike that species; the outer case tightly adheres to the inner, and is hard woven and 

 giniinied, and has the appearance as though made of rough silver, not as in 5. Columbia with a few silver threads streaked through here 

 and there, but the entire cocoon looks as if woven of coarse large fibres of rough silver, and is very beautiful in<leed. Were it not for 

 these wonderful features of the cocoon I sliouhl unhesitatingly pronounce Gloveri but the -A rizona or I'tah form of Cecropia, for the per- 

 fect in.secls dillcr in notbiug but the ground colour of wings. Dr. Hagen is of the opinion that Gloveri is a form of Columbia, but as just 

 stated I rather think it a variation of Cecropia and have little doubt that successive breedings of it in the Atlantic Slates would eventu- 

 ally change the crimson ground colour to the black of Cecropia. The figure S on plate XIV represents a most astonishing semi-albina 

 9 aberration, the left wings of which are normal and the right aresufiused with white to the complete extinction of the crimson ground 

 colour, with the exception of a small basal patch on j)rimary ; the iliscal lune on primary is surrounded by a black shade, that on sec- 

 ondary is faintly outlined with grey. The under surface of this monstrosity is normal on both sides. There is a difference, as the 

 figure shows, in the outline of the wings, especially of the primaries, that of the abnormal side being much more arched and fuller on 

 the costa. This strange freak was captured in inner .Arizona. 



The preponderance of )>alc coloured or alliinons species and cxamides in the sail regions of Arizona and I'tah, is truly won- 

 derful and without ]ireceilent. What the cause can be, climatic cu- local, that results in the production of these astonishing forms is a 

 question which opens a fiehl of investigation of unparallelled intere.st to every student of natural science. 



BUNAEA EP»LIS. Stueck. 



(PLATE XIV, 1>'IG. 9, cf.) 



Of this species, described on page 121, from a single example presented to me by my ever dear friend Mr. Chapman, of Glasgow, 

 Scotland, Prof We.stwood informed me that there are examples in the Oxfijrd Museum, and suggested that it might perhaps be a form 

 of B. Phcedusa, Dru. 



NEW SPECIES, ^'AlUETIES, ETC. 



P.<PII,I0 {Anterius) var. Utaiiensis, n. var. (^, wings somewhat narrower than in the common form ; primaries more falcate. 

 Pale yellow stripes on each side of the head and protborax ; teguhe also pale yellow ; usual lateral rows of yellow dots on abdomen ; 

 anal valves pale yellow. Macular baiiils and lunules pale ycHow on both surfaces, without the orange colour so conspicuous on the 

 under surface of the ordinary examples; the mesial band of secondaries does not extend into the discoidal cell on the upper surface, 

 in cell on under surface are a few yellow s<'ales; anal eye a.s in common form ; submargiual row of spots on under surface primaries 

 conlluent in some exampli's, seiiaralcd by the ncrvurcs only in others — piincipally it difl'iTs from AKieriiis in the head and thorax being 

 striped instead o( spotted, in the yellow anal valves, in the dillerent shape of the wings, in the yellow spots and bauds being very mucli 

 paler on both surfaces; in the mesial macular band being, especially on secondaries, much narrower, and in the submarginal spots of 

 primaries, on under side, being confluent or almost so. .Vll the examples I have seen are of larger size than the common run of Asle.riini, 

 though not larger than some examples of the latter. The 9 differs from the (^ prini'ipally in the partial obsolescence of the mesial 

 macular bands. Hah. Utah. 



Pap. Rutulus, var. or ab. ? ^ expands 2| inches. Upper surface same shade of yellow as in the ordinary form, black bands 

 and margin all very broad as in the heavier marked examples of P. EiirymeAon; the broad black ex'erior border of primaries on its 

 inner edge between the fifth subcostal nervule and the second discoi<lal nervule is extended abruptly in a bow inwards from the regular 

 line until it is almost merged into the abbreviatid transver.se ban<l ; the submarginal row of vellow spots on |)rimaries very small, and 

 the tliree nearest apex not in a line with the others but iient off at the second discoi<lal nervule ; on the secondaries the yellow submar- 

 ginal lunules or bars rather of diversified style and size; the apical one is a very narrow bar, a mere line; the one between the first and 

 second subcostal nervules is far broader than in most cases: that between the second subcostal and di.scoidal nervules is a bar of great 

 size, being twice the length of the last or of the one following it, which with the one between the first and second median nervules is 

 crescent shaped and of large size; the next as well as the anal mark are exceedingly small and rust red; above these two latter, but 

 with a considerable interspace between, are crescents of no great size formed of blue scales. 



Under surface bands, etc., not quile as heavy as above; primaries, the inner edge of black margin does not extend inwards be- 

 tween the fifth sub<'ostal and .second discoidal nervules nearly so much as on the up|ier surface; the submarginal yellow spots are con- 

 fluent, forming a broad unbroken band which covers the outer half of the black marginal band and separated from the exterior margin 

 by little more than a black line. Secondaries, ali the submarginal yellow bars very large and almost confluent at their angles, the one 

 between the first and second median nervules, which is largest, is lunate, the others parallelogramic in shape; interior to these are the 

 .sliining blue and greenish as in the normal form. 



The body and head above black with but little indication of yellow on the pat.agise. Several examples from Arizona.
