LI PA RA BOMBYCOIDES. 
most of the American Lepidopterists consider it a synonym, I have designated on page 117 of this volume (after the description of 
Sph. Uarrisii). The present figure on accompanying plate XIV was carefully made from Prof. Westwood’s drawing, above alluded to. 
Although the type was taken in Canada, nothing of the kind is known to exist in any American collection ; it approaches nearest 
to Sph. Uarrisii, but the latter, which I have figured on plate XIII, f. 16, though having much the same general appearance yet differs 
considerably in detail, though Bombycoides may possibly be an aberration of it. That it is however a distinct species that is vet to be 
re-discovered is after all not unlikely when we consider that such a conspicuous species as S. Plota escaped the notice of the many 
American collectors and students until three years since when 1 detected it in a small collection sent me from Montreal, Canada. If I 
have been able to do little towards elucidating the mystery that enshrouds Bombycoides, 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 its appearance. 
SAMI A GLOYERL Streck. 
Since figuring and describing this species in the commencement of this work I have received through Mr. N eumoegen a number 
of cocoons from Utah and Arizona which developed in due time the perfect insect. It is subject to the same variations as Cecropia in 
size of discal lune, breadth of white transverse bands, etc., etc.; also varying considerably in size, the largest being six inches in ex- 
panse, the smallest but four. Some examples are much paler than 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. Cecropia though not so large and unlike that species ;' the outer case tightly adheres to the inner, and is hard woven and 
gummed, and has the appearance as though made of rough silver, not as in S. 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 indeed. Were it not for 
these wonderful features of the cocoon 1 should unhesitatingly pronounce Gloveri but the Arizona or I tab form of Cccropui, for the per- 
fect insects differ in nothing 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 States w ould eventu- 
ally change the crimson ground colour to the black of Cecropia. The figure 8 on plate XIV represents a most astonishing semi-albina 
9 aberration, the left wings of which are normal and the right are suffused with white to the complete extinction ot the crimson ground 
colour, with the exception of a small basal patch on primary ; the discal 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 fide being much more arched and fuller on 
the costa. This strange freak was captured in inner Arizona. ( 
The preponderance of pale coloured or albinous species and examples in the salt regions of Arizona and Utah, is truly won- 
derful and without precedent. What the cause can be, climatic or local, that results in the production of these astonishing forms is a 
question which opens a field of investigation of unparallelled interest to every student of natural science.

(PLATE XIV, FIG. 9, tf.) 
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. Westwood informed me that there are examples in the Oxford Museum, and suggested that it might perhaps be a form 
of B. Phoidusa, Dru. 
NEW SPECIES, VARIETIES, ETC. 
Papilio (Asterius) var. Utahensis, n. var. wings somewhat narrower than in the common form ; primaries more falcate. 
Pale yellow stripes on each side of the head and prothorax; tegnke also. pale yellow ; usual lateral rows of yellow dots on abdomen ; 
anal valves pale yellow. Macular bands and lunules pale yellow 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 scales; anal eye as in common form ; submarginal row of spots on under surface primaries 
confluent insome examples, separated by the nervures only in others — principally it differs from Asterius in the head and thorax being 
striped instead of spotted, in the yellow anal valves, in the different shape of the wings, in the yellow spots and bands being very much 
paler on both surfaces; in the mesial macular band being, especially on secondaries, much narrower, and in the snbmarginal spots of 
primaries, on under side, being confluent or almost so. All the examples I have seen are of larger size than the common run of Asterius, 
though not larger than some examples of the latter. The 9 differs from the $ principally in the partial obsolescence of the mesial 
macular bands. Hah. Utah. 
Pap. Eutclus, var. or ab. ? <$ expands 2f 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. Eurymedon ; the broad black ex'erior border of primaries on its 
inner edge betw'een the fifth subcostal nervule and the second discoidal nervule is extended abruptly in a bow inwards from the regular 
line until it is almost merged into the abbreviated transverse band ; the submarginal row' of yellow' spots on primaries very small, and 
the three nearest apex not in a line with the others but bent off at the second discoidal 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 discoidal 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. 
Linder surface bands, etc., not quite as heavy as above; primaries, the inner edge of black margin does not extend inwards be- 
tween the fifth subcostal and second discoidal nervules nearly so much as on the upper 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, all 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 
shining blue and greenish as in the normal form. 
The body and head above black with buL little indication of yellow on the patagise. Several examples from Arizona.
