PSEUDOSCHXENOBIUS OPALESCALIS. (Plate VI., fig. 13.) 



Schoenobius opalescalis Hulst, Trans. Am. Ent. Soc Vol. XIII., 

 p. 167 (1886). 



Expanse of wings, 29 mm. Palpi dark fuscous, cinere- 

 ous above ; head and thorax cinereous, the tegulse edged 

 with white ; abdomen fuscous, annulate with cinereous ; 

 fore wings cinereous, with white scales scattered profusely 

 between the veins ; fringe of the same color as the wings. 

 Hind wings above and beneath light fuscous, somewhat opal- 

 escent. Under side of fore wings fuscous, paler towards 

 the apex. Described from six examples in my collection, 

 from Arizona ; one in the collection of the National Mu- 

 seum, from the Argus Mountains, Cal. ; and the type in the 

 collection of Mr. Hulst. 



CRAMBUS FABRICIUS. 



Head medium ; face rounded, more or less swollen or 

 cone-shaped ; eyes more or less hemispherical ; ocelli pres- 

 ent ; antennae about two-thirds as long as the costa, dentate 

 or ciliate in the male (Plate B, fig. 17), simple in the female 

 (Plate A, fig. 9) ; labial palpi very long, porrect ; maxillary 

 palpi moderately long, porrect, triangularly dilated with 

 scales (Plate C, fig. 16); tongue well developed; thorax 

 smooth ; abdomen of the male with a small anal tuft. 



Fore wings from two to three times as long as wide, with 

 twelve veins; 4 and 5 sometimes from a stalk; 7, 8 and 9 

 from a common stalk; 11 bent more or less and sometimes 

 connected with 12. Hind wings about one and one-half 

 times as long as wide ; veins 4 and 5 from one point or from 

 a stalk. 



This genus contains by far the largest number and the 

 most common of our species. From the studies of Riley, 

 Lintner, Forbes, Felt, Beckwith and Miss Murtfeldt, we 

 know something of the early stages of a large number of 

 our species.
