NO. 3551 EUCHROMIUS — CAPPS 5 



Female. — Alar expanse 14-22 mm. Similar to male in color and 

 maculation. 



Genitalia (fig. 7): Hooklike sclerotization laterad of ostium greatly- 

 expanded basally. Ductus bursae short; distance from ostium to 

 origin of ductus seminalis about one-third that from ductus seminalis 

 to tip of bursa copulatrix. Two subequal signa, narrow, ridgelike. 



Lectotype. — Male, in collection of Museum of Comparative 

 Zoology, MCZ type no. 14297, present designation. 



Type locality. — California. 



Food plant. — Unknown. 



Specimens examined. — 54. 



Distribution. — California, Washington, Idaho, Montana, Utah, 

 and Colorado. 



Kemarks.' — E. californicalis was based on three males. Only two 

 of the syn types were located, both at the Museum of Comparative 

 Zoology. One is without an abdomen; that with the abdomen is 

 made lectotype of the species. The genitalia of the lectotype have 

 been examined by brushing. 



The illustration of Corbet and Tams (1943) of californicalis female 

 genitalia does not agree with those of specimens in the U.S. National 

 Museum. Their figure is definitely not of californicalis but of an 

 abnormal specimen of ocelleus or of a species unknown to me.

Eromene ocellea (Haworth). — Schaus, 1923, Zool. Sci. Zoologica, vol. 5, no. 2, 

 p. 29. 



Male. — ^Alar expanse 16-21 mm. Resembling ocelleus, but differ- 

 ing from it as follows: Facies somewhat darker. Upper surface of 

 forewing smoother in appearance, the whitish ground color heavily 

 overlaid with brown from base of wing to inner transverse postmedial 

 band and with Httle or no irroration; irroration beyond outer trans- 

 verse postmedial band more blackish and denser; the ochreous trans- 

 verse postmedial bands straight or bent outwardly. Hind wing with 

 subterminal line brownish and more diffuse. 



Gentialia (fig. 2): Uncus moderately stout, somewhat dilated 

 between base and tip. Harpe with costal serration weak; basal 

 production of costa rounded at apex, the hooklike spine from below 

 apex. Aedeagus (fig. 2a) with an elongate series of short, stout 

 spines and two basal patches of small, slender spinides. 



Feivu-le (pi. 1: fig. 1). — Alar expanse 16-22 mm. Similar to male 

 in color and maculation. 



Genitalia (fig. 6) : Ventral margin of ostium rather broad, imdulate, 

 strongly sclerotized, and finely spinulate. Ductus bursae long,
