thickness of head, 0.273; width of vertex at anterior ocellus, 0.120; width 
of mesoscutum, 0.393; length of forewing, 1.12; width of forewing, 
0.422 mm. 
Described from one female (holotype), collected on Mt. 
Kaala, Oahu, between 2500 and 3000 feet elevation, July 22, 
1917 (Timberlake). 
Hypergonatopus brunneipes n. sp. 
Female. Very close to vulcanus, but having the head somewhat broader 
and slightly thinner fronto-occipitally; thorax more robust and wider, 
the scutellum wider across the base; sculpture of the mesonotum some- 
what coarser, and the pubescence of the mesoscutum very much sparser; 
setae in the hyaline area near base of forewing greatly reduced in size 
and hyaline; marginal vein about 2.7 times longer than the stigmal, the 
latter enlarged at apex and curved towards the costal margin. 
Coloration similar to vulcanus, the head with a rather weak bluish 
and purple luster on the frontovertex; the mesoscutum and apex of scutel- 
lum metallic green, the abdomen above and side of propodeum with a 
strong purple luster, changing to greenish in some aspects on the basal 
tergite, the venter with a greenish luster; mesopleura dark brown, shin- 
ing but hardly metallic; antennae and legs dark brown, with apex and 
base of front tibiae, apex of middle femora, apical half of hind tibiae, 
and front and hind tarsi pale brown, the trochanters, annulus at base 
of femora, apical third of tibiae and the tarsi of middle legs yellowish. 
In one specimen (paratype) the pleura and legs are much paler brown. 
Wing markings similar to vulcanus, but much fainter. 
Length of body (1.01 to 1.16), 1.14; length of head, 0.386; width 
of head, 0.473; thickness of head, 0.249; width of vertex at anterior 
ocellus; 0.120; width of mesoseutum, 0.412; length of forewing, 1.06; 
width of forewing, 0.403 mm. The head is slightly shrunken, but the 
measurements are believed to be tolerably accurate. 
Male. Very similar to the male of vulcanus, but differing in the 
same way as the female in regard to the sculpture, pubescence and wing 
characters. Coloration similar to that of the female but the upper part 
of the face and the frons with a greenish luster, the lower part of the 
face, the cheeks and vertex with a purple luster, and the pleura, antennae 
and legs are rather pale brown. Wings almost hyaline, excepting a 
small spot beneath the marginal vein. 
Length of body, 0.98; width of vertex, 0.174; width of mesoscutum, 
0.396; length of forewing, 1.05; width of forewing, 0.417 mm. The head 
is so much shrunken that other measurements are not possible. 
Described from three females, one male (holotype, allotype, 
and paratype), reared from a Dryinid cocoon, probably of 
Pseudogonatopus perkinsi (Ashmead), reared in turn from 
Ilburnia koae (Kirkaldy), Kilauea, Hawaii, January, 1915 
(F. Muir).
