tex is vtsLially open in front, its maVgins continuous with the 

 margins of the frontal costa ; the median carina of the pro- 

 notum is higher and more distinctly arched, the angle of the 

 anterior more distinct, and of the posterior margin more 

 acute.

This species is not common, at least has not been taken 

 in as large numbers as the other species oi Arphia. It varies 

 very much in color, some specimens being almost black, 

 others bright reddish or yellowish-brown; in the east it is 

 entireK^ yellow-winged, in the central states frequently 

 orange- winged. It is found in the same localities, among 

 grass and low bushes in barren fields or pastures on dry soil, 

 as the very common sulphurea, but is lound much later in 

 the season, not before the first of August. According to 

 Morse the two specimens xanthoptera and sulphurea can be 

 readily separated. The hind process ot pronotum of the 

 former is acute-angled in dorsal view, its sides concave. 

 Carina of pronotum in a side view crest-like, high, arched 

 and compressed. Fig. 80. Dusky bandof wing with sub-frontal 

 shoot usually extending one-fourth to one-third the distance 

 across disk to base of wing. In sulphurea the hind process 

 of pronotum is about right-angled in the male, or a little ob- 

 tuse in the female; carina rather low. Dusky band of wing 

 with sub-frontal shoot usually extending two-thirds of the 

 distance to base of wing. 



Arphia carinata Scudder. 



Head blackish, profusely streaked and spotted with dull 

 bluish-white; frontal carinas and upper border of clypeus 

 edged with whitish; palpi blackish, the joints tipped with
