recall Anticlea derivcda (Schiff.), etc. 
CiiRiSMOPTERYX (Prout), nov. gen. (praec. subgen.?) 
Face prominent, horny, with strongly appressed scales, not tufted ; 
palpus rather strong, of moderate length, somewhat up-curved, with 
.s/iorfZ|/projecting scales* ; tongue strong ; antenna rather long, in 
rather thick, with short, even ciliation, in 9 slender, minutely cili¬ 
ated. Legs rather slender ; hindtibia fully spurred. Forewing 
with double fireole, the outer long, SC^ anastomosing with SC^'"* only 
just beyond SC*, or almost at the point of their separation, stalked 
(sometimes quite considerably) with SC**, DC* inbent, R* normal. 
Hindwing rather long and narrow, particularly in 9 i being some¬ 
what produced apically, but with angles moderately rounded off ; C 
anastomosing with SC nearly to end of cell, SC* stalked with R\ dis- 
cocellulars not biangulate, R* normal, DC* first slightly inbent, then 
oblique outwards. Wing-margins entire or very faintly crenulate, 
scaling very glossy, fringes very long. 
Type of the genus: Chrismeypteryx expolita, Prout, 
nov. sp. 
I can find no existing genus to Avhich the species about 
to be described can satisfactorily be assigned. Yet it is 
not without considerable reluctance that I erect a new one 
for them, as their distinctive characters—face, palpus, wing- 
shape and texture — seem comparatively slight, and they 
may possibly be connected with normal species of Euphyia 
by intergrades. In the shape of the hindwing, and in the 
shiny, almost greasy appearance of the wings, they some¬ 
what remind of some of the species oi Larentia" (sens, 
lat.) of the Alps of Europe, such as anstriacaria H.-S.; but 
these have biangulate discocellulars in the hindwing, and 
normal face and palpus.

* In one specimen tliere seems one little tuft of strong, coarse 
scales, but in any case the general contrast with the longish-fringed 
palpus of Euphyia (and indeed most Larentiids) seems fairly note¬ 
worthy.
