Key to Species 
1. Antennae pale chestnut-brown. Eyes covered with 
blackish-brown hairs, contiguous over about one-half 
of the length of the frons (in male) ; ocellar triangle 
about as long as wide. Wing subhyaline, slightly 
yellowish along costa H. vitalisi J. Bequaert. 
Antennae bright yellow. Eyes covered with pale yel- 
lowish hairs, contiguous (in the male) or closely ap- 
proximated (in the female) over one-third of the 
length of the frons; ocellar triangle longer than 
wide. Wing fairly uniformly yellowish-gray, more 
ochre-yellow along costa. . . .H. ochracea Lichtwardt.

Specimens Examined. — Laos : one male without more 
definite locality; two females, one the allotype, Pak Hang, 
Prov. Xieng Khouang (or Chieng Khuang), March 2, 1915 
(R. Vitalis de Salvaza Collector). 
I have compared these specimens with the holotype at 
the British Museum. The alula in this species is broader 
than in H. austeni, H. opaca, and H. cingulata. 
Female (undescribed). — Differs scarcely from the male 
and is readily associated with it. The eyes are not properly 
speaking contiguous, but over about one-third of the length 
of the frons, below the ocellar triangle, they are separated 
by an extremely narrow area, which measures less than 
the width of the anterior ocellus. 
Length (without ovipositor) : 16 to 16.5 mm.; length of 
wing: 18.5 to 19 mm.; width of wing: 4.8 to 5 mm. 
The allotype is at the M. C. Z., Cambridge, Mass. 
In the two females the wing venation is normal and about 
the same in both wings ; in the male, that of the left wing 
is normal, while in the right wing there is a supernumerary

by Brunetti.
