tHE CANADIAN ENTOMOLOGIST. (36 



resembles in shape and ornamentation that of Chrysophanus T/ioe, where- 

 as the egg of Sinmtheus is hke a Lycaena, as L. Pseudargiolus). 



Young Larva. — Length at a few hours from egg, .08 inch ; shape and 

 markings of Smintheus at same stage ; tapering on dorsum and sides from 

 3 or 4 to 13 ; the segments well rounded ; color black, legs black, under 

 side and pro-legs dark greenish-brown ; on dorsum and sides black hairs, 

 which spring from tubercles just as in Smintheus, the arrangement being 

 of same description ; head ob- ovoid, depressed at top, the vertices 

 rounded ; surface rough ; color black ; much covered with short black 

 hairs. 



The larvce refused to eat Sedum, and soon died. In 1878, Mr. Mead 

 brought from Nevada a large number of these eggs, obtained by confining 

 the females on Sedum. 1 kept them in a cool room till last of Jan., '79, 

 when they were placed in a warm one. A few larvae hatched 31st Jan. 



A NEW ARCTIAN. 



BY HENRY EDWARDS, NEW YORK. 



Nemeophila Selwynii, n. sp. 



Head, thorax and abdomen, dull sooty black. Palpi, collar and tip of 

 abdomen pale dull orange. Tegulse, sides of abdomen and upper side of 

 the tip of antennse sordid white. Wings dull sooty black. At base of 

 primaries a very distinct and clearly marked short white streak, and an 

 oblique band (also cream white) from behind the middle of the costa to 

 near the internal angle. This band, which is excavated at its junction 

 with the cell, gradually narrows to a point as it reaches the outer margin. 

 The fringe is white on the apical half of the margin, black elsewhere, and 

 there is a small orange dash at the base of the costa. Secondaries wholly 

 sooty black, fringe white, a little below the apex. Beneath the wings have 

 a slate-colored shade, the markings of the upper surface repeated, the 

 costa of primaries stained with orange at the base and at the edge of the 

 white oblique band, while that of the secondaries has two whitish triangu- 

 lar blotches. 



Expanse of wings, 35 m.m. Length of body, 13 m.m.

Though the species of the genus Nemeophila are subject to consider- 

 able variation, I can but believe that in the form before us we have to do
