commences at the second transverse cubital nervure. The apex only of the posterior 

 tibiae is fuscous. 



From H. nigriceps it differs in having two vittse on the mesonotum, no black mark 

 on the pectus, while only the tips of the tarsi are black ; the third transverse cubital 

 nervure is not curved, nor is the third cubital cellule wider above than below, as it is 

 in nigriceps, while it is perceptibly shorter (especially on the upperside) than the 

 second ; the transverse median cellule is received before the middle of the cellule ; 

 and the second recurrent nervure is received further from the second transverse cubital.

Lutea, antennis (basi excepta) vertice laete, mesosterno, abdominis apice, tarsis tibiarumque apice nigris ; alis 

 flavescenti-hyalinis, apice cseruleo-fumato, cellula cubitali tertia apice producto, stigmate et costa testaeeis.

The antennae are a little shorter than the abdomen, thickly pilose, the two basal 

 joints testaceous, the base of the terminal joint more or less fuscous. The face from 

 below the frontal area with the mandibles pale testaceous ; the apex of the mandibles 

 piceous ; behind the ocelli the head is brownish testaceous. The frontal area is rounded 

 behind, projecting at the sides at the frontal ridge, the apex is truncated. The antennal 

 fovea tapers gradually to the apex ; at the base is a raised point. The third cubital 

 cellule is much wider above at the apex than it is on the lower side ; the second 

 recurrent nervure is received very close to the second transverse cubital. The spurs 

 and calcaria are white. 



What is probably the male agrees with the female in coloration, -except that the 

 vertex is entirely black, or very nearly so ; the frontal area is sharply pointed behind, 

 not rounded as in the female, while the third cubital cellule is not nearly so much 

 produced at the apex.
