luteous. Pronotum (Fig. 80), dull, dark, brownish-fuscous, 

 with a short pale streak behind the lower edge of the eve; 

 hind edge of pronotum forming less than a right angle; 

 median carina very prominent, whole, sharp, rounded. 

 Basal third oftegmina dark brownish fuscous; beyond ash- 

 gray, profusely and rather regularly sprinkled with small 

 brownish spots; basal half of wings pale dull orange, 

 bordered b\^ a broad blackish fuscous band, occupying the 

 rest of the wing, excepting the apex, and encroaching on 

 the orange near the costal margin, as in xanthoptera; apex 

 semi-pellucid, a little fuliginous, darker at the very tip. 

 Hind femora dull, dirty, hoary without, black with three 

 transverse white bands within, the tibiae blackish-brown 

 with black spines and a broad pale band near the base. 



Length 30 mm. 



This species occurs with the two others already described 

 but is by no means common. It can be readily dis- 

 tinguished by the facial costa, which is acuminate towards 

 the vertex in sulphurea, while in carinata the sides of the 

 facial costa are nearly parallel from the median ocellus to 

 the vertex. The carina of the pronotum of the latter is very 

 high and strongly arched, while in the former it is but little 

 elevated and nearly straight. This insect flies late in 

 August. 



Arphia tenebtosa Scudder. 



Closely allied to sulphurea. Upper part of the head 

 regularly convex ; central foveolaof the vertex sub-elongate, 

 with a slender median carina, and a transverse sulcus across 

 the hinder portion, generally truncate and closed in front ; 

 upper part of the frontal coxa sub-tricarinate ; rest flat, 

 arcuate below as seen from the side. Antennae slightl}^ 

 flattened and somewhat enlarged toward the tip. Median 

 carina of the pronotum distinct, somewhat prominent but 

 less so than the sulphurea, nearly straight on top, cut near 

 the middle by the transverse sulcus, but not notched ; an-
