CHRYSOCRASPEDA; COSYMBIA. By L. B. Prout.

13. Genus: Chrysocraspeda Hmpsn. 
A more specialized development from Ptochophyle , differing in the loss of the areole of the forewing, 
all the subcostals arising from a common stalk. Chiefly Indian, but including a few African species; see Vol. 16, 
p. 51. 
charilcs. Ch. charites Ob. (4 d). Only known from a single, somewhat damaged $ from Akbes, Amanus Moun¬ 
tains. Closely similar to auristigma Prout (New Guinea, etc.) and phaedra Prout (Sudest Island) but some¬ 
what darker and with the cell-spot of the forewing large and whitish. Dr. Wehrli has kindly examined the 
structure and says that the venation agrees. Its occurrence in this definitely Palaearctic locality is so sur¬ 
prising that one wonders whether there can have been a mistake in labelling the specimen. 
14. Genus: C'osymbla Him. 
The two-fold division, according to the structure of the genitalia (see Vol. 4, p. 141), is regarded 
by Pierce as generic. He calls group 2, with the well-developed forceps (“plate of sacculus” of Pierce) Co- 
donia Hbn. ; group 1 {Cosymbia sens, str.), of which I only wrote 1 ' forceps wanting or rudimentary”, is really 
characterized by the long curved arm (“fibula” of Bastelberger) which is attached to the base of the valve. 
The grouping, though certainly important, does not seem to me to be of generic value; porata and the new 
North African form described below furnish transitions. 
impictaria. 0. pendularia Cl. ab. impictaria Meves has the ground-colour inclining to yellowish, the markings want- 
decoraria. ing, excepting weak discal rings and the terminal black dots. One bred at Vaxholm, Sweden. — ab. decoraria 
Newm. (= nigroroseata H. W. Wood , nigrosubroseata Bowman ) (4 d). I have since seen the type-form of this 
subroseata. in some numbers from Surrey, and figure a good $. — subroseata Woodforde (Vol. 4, pi. 5 c, as decoraria), only 
known to me from N. Staffordshire, where it is almost a race, is not quite the same as decoraria, though indi¬ 
vidual aberrations closely approach it. Normally, subroseata has the rosy tone predominating, while decoraria 
orbiculoides. is more black-grey. — ab. orbiculoides Woodforde, founded on a single specimen which was bred among a dark 
series of subroseata, is dark grey with the black vein-dots of both lines enlarged, the outer series followed by 
hatertica. a pale band, altogether recalling orbicularia. — ab. hatertica V. Schultz differs from the other rayed forms 
(radiata and nigrostriata) in that the two lines of the forewing are thickened, greatly approximated posteriorly, 
the strong dark vein-marks of the postmedian therefore almost m e d i a n. Bred from a larva from Hatert, 
aestiva. Venn, Holland. — f. aestiva Vorbrodt. “Quite strikingly small and pale, more weakly marked”. Founded on 
griseolata. second-brood specimens from Italian Switzerland. — griseolata Stgr. (4 e). This name should be restricted 
to the E. Asiatic race, which is certainly not identical with the weakly marked greyish forms of Europe, but 
is characterized by a peculiar yellowish tone and denser irroration. Osthelder proposes to apply to the so- 
called “ griseolata” of Europe the name (ab.) obsoleta Lambill. (the name of circularia F. cannot be revived for 
it, as it is preoccupied). 
albiocella- C. albiocellaria Hbn. Warnecke and others have recently given careful attention to this species and 
Ho. the following, particularly as regards their geographical distribution. It appears that some of the records 
are based on misiclentifications; see under lennigiaria. Yet the true albiocellaria does occur in France (Hautes 
Alpes) and probably its distribution is as wide as is indicated in Vol. 4, with the addition — according to 
some reliable observers — of Spain. 
lennigiaria. C. lennigiaria A. Fuchs. In all its colour forms distinguishable by the smaller and more oval cell-spots, 
the difference generally particularly striking on the hindwing. The investigations of Warnecke and Lhomme 
have shown that its distribution largely follows that of its foodplant, Acer monspessulanum, and that most 
occidenta- of the supposed French albiocellaria really belong here. — occidental^ I). Luc., though described as a variety 
lis - of albiocellaria , is certainly this French lennigiaria , which (according to Warnecke) differs from the Rheingau 
type as follows: Ground-colour purer and a little lighter, the dark parts of the median seem better delimited, 
but more material would be required in order to establish its constancy as a race. Litcas notes “the intense 
and irregular distribution of the black parts”. His locality was Poitou; authenticated French records of lenni¬ 
giaria are from Lot, Basses-Alpes, Ardeche, Charente Inferieure and Deux-Sevres. The Tring Museum has 
mauretani- two poor specimens of the aestiva form from Bouches-du Rhone. — niauretanica Reisser has just been described 
ca - from the Riff Mountains, Morocco. Lighter than the name-type, more yellowish, especially in distal area, the 
black postmedian and generally the median shade lessd eveloped, inclined to reduce to irregular irroration. 
sertaria. G. annulata Schulze ab. sertaria Dannehl. Shading between median and postmedian lines intensified, 
extenuata. forming an almost black band, developed also on the hindwing. Tyrol. — ab. extenuata Dannehl is the anti¬ 
thesis of sertaria, the dark irroration between median and postmedian entirely wanting, sometimes the median 
itself also wanting. Magdeburg, the Sabine Mountains, etc., probably general with the type.
