464 (669%). Melanorhopala infuscata Parshley, 1917b, 19. 



Macropterous form — Elongate-oval, widest at middle of elytra. Dull 

 brownish-yellow, the cells of costal area hyaline; fourth antennal and 

 some small scattered spots on elytra, fuscous-brown ; legs and remainder 

 of antennae paler brownish-yellow; femora marked with small vague 

 brownish dots; sides of sternal sulcus whitish; genital plate and sides 

 of ventrals often tinged with fuscous. Joints of antennae cylindrical, of 

 nearly equal thickness throughout, 1 only about one-third longer than 2, 

 3 more than twice as long as the others united ; 4 fusiform, pilose, about 

 as long as 1. Spines of head closely appressed. Pronotum elongate 

 pentagonal, disk at middle convex with lateral angles obtuse; carinas 

 fully as high as margins, median one percurrent, the others abbreviated 

 in front. Elytra surpassing abdomen by one-fourth their length, grad- 

 ually slightly widened from base to middle, thence feebly narrowed with 

 margins visibly sinuate, their tips broadly rounded ; apical two-thirds of 

 costal area with two or three rows of rather large cells, basal third often 

 with but a single row. Length, 5 — 6 mm. 



Great Falls, Va., Aug. 21 (Barber) . Recorded only from Vir-

 the areas limited by carina-like veins ; costal area with one to
