angle. The fringes are blackish. Hind wings obscure yellow centrally with 

 the veins marked with fuscous and with a diffuse fuscous costal and external 

 shading which clouds also the base of the wing and the internal margin ; 

 fringes pale. Body blackish ; abdomen ringed with whitish. Beneath both 

 wings are yellow with narrow blackish external borders ; the hind wings show 

 a black discal dot and a second, larger, without on the costa. The fore wings 

 have the nervules marked with fuscous and are clouded at base, and show a 

 discal liture and two broader oblique dark costal shades before the apex. 



Expanse, 20 m. m. Habitat, California, Sierra Nevada (coll. Mr, 

 Hy. Edwards, No. 2590). 



Two female specimens are before me agreeing in all their mark- 

 ings. I liave compared the species in the body of the description 

 with its nearest ally hitherto known to science. 



Syneda Howlandii, Orote. 



Habitat, Cahfornia (coll. Mr. Hy. Edwards, No. 240). The speci- 

 men does not seem to diflFer from my original types except by the 

 bands on the secondaries being a little broader superiorly. 



Euelidia cuspidea {Buhner). 



Habitat, California (coll. Mr. Hy. Edwards, No. 90). The speci- 

 mens are not to be distinguished from our Eastern material. 



Drasteria coiivalescensj Guenee. 



I have taken this species in Central Alabama. It falls into a dis- 

 tinct section of the genus from the pectinate, geometriform anten- 

 nae of the male. 



Drasteria erichtoj Ouenee. 



I have a single ? specimen in the collection, from New York, which 

 agrees with Guenee's description in the continuity of the transverse 

 posterior line. From the distinctness of the black subapical marks 

 it seems to bear out the remarked resemblance to Euelidia. But I 

 think that it is a form of our usual species occurring plentifully in 

 this vicinity in April and May, and which expands uniformly about 

 37 m. m., and for which I retain this name. By breeding the species 

 we shall discover whether this and the following are not forms of 

 one species.
