CRAMBUS LUTEOLELLUS UL^E. (Plate IV., fig. 6.) 



Crambus nice Ckll., Ent. Mon. Mag., Vol. XXIV., p. 272 (1888). 

 Crambus nice Fern., Ent. Am., Vol. IV., p. 44 (1888). 



Expanse of wings, 24 mm. This variety differs from the 

 description above only in being a little more ashy beyond 

 the cell. This species is so exceedingly variable that at first 

 I was not disposed to consider this insect (the type of which 

 Mr. Cockerell very kindly gave me) even as a variety. 

 I have before me another specimen, from Arizona, almost 

 identical with Mr. CockerelFs type, and another from Colo- 

 rado, which is intermediate between this type and some of 

 the eastern forms of luteolellus. I am now inclined to think 

 that it may be well to consider nice a geographical variety 

 of luteolellus, but perhaps more material and further study 

 may lead me to modify even this opinion. 



Habitat. Colorado, Arizona. Early stages and food 

 plant unknown. 



I saw the type of Crambus innotatellus Walk, in the 

 British Museum, but could not study the structure of it. 

 I think it may prove to belong to the genus Chilo. 



THAUMATOPSIS MORRISON. 



Face rounded ; eyes large, hemispherical ; ocelli present ; 

 antennae scarcely more than half as long as the costa, pecti- 

 nate or bipectinate in the male ; labial palpi porrect, about 

 as long as head and thorax ; maxillary palpi about as long 

 as the head, and triangularly scaled; tongue short; thorax 

 smooth ; abdomen in the male with a small anal tuft. Fore 

 wings with twelve veins, 7, 8 and 9 from one stalk, all the 

 rest separate ; cell closed. Hind wings with eight veins, 4 

 and 5 arise near each other or from one point; cell open. 

 Mr. Morrison redescribed pexellus Zell., and established the 

 genus Thaumatopsis for it. In 1894 Mr. Grote established 

 the genus Propexus, with edonis as the type ; but, as pexel- 

 lus and edonis are congeneric, we have adopted the older 

 generic name.
