sides of the eyes, centre slightly impressed; antenna

as the first, fourth about as long as the second, fifth rather 
longer; pronotum black or brown, punctured, much 
widened posteriorly, shghtly constricted before the middle, 
with a wide central channel in front, and a small fovea on 
each side; posterior angles rounded, base slightly produced 
and rounded; scutellum black; elytra with the clavus 
submembranous, white at the base, corium brown, clothed

H. ruficeps, 7oms.—Dimorphous, and differing from 
the preceding in having the basal joint of the antennz 
much shorter, scarcely projecting beyond the apex of the 
head, in the paler reddish head and pronotum, the unspotted 
membrane, and the undefined basal spot on the base of 
the clavus. In the only developed specimen before me, 
from Mr. Billups’ collection, the whole clavus is white, and 
the corium has a pale central line. In the undeveloped 
form the pronotum is less widened posteriorly, and the 
elytra are reduced to two small straight lobes, with a small 
membranous dilatation on their inner margins, hardly longer 
than the scutellum.
