Male. Very similar to the female in structure and coloration; eyes 
somewhat smaller, the ocelli larger, the frontovertex proportionately a little 
broader; secrobes proper of the face considerably wider, curved, and prac- 
tically meeting above; antennae of the same general structure, but the 
scape is a little wider and with a distinct broad emargination on dorsal 
margin just beyond the middle, the club solid, much slenderer, and much 
more obliquely truncate from below upward; abdomen smaller or not over 
one-half as long as the thorax, the venter with a median fold. General 
color paler yellow than in the female, or about empire yellow (Ridgway), 
the dorsum of the thorax, however, more or less cadmium yellow, the 
underparts of thorax, coxae, and femora nearly Martius yellow (Ridg- 
way); black markings on the metanotum, propodeum, and abdomen much 
more prominent than is usual in the female, the abdominal mark being 
triangular in shape and pale in the center.

Described from the following material reared from Pseudo- 
coccus nipae (Maskell) from the State of Vera Cruz, Mexico 
(H. T. Osborn) : 68 females, 11 males (holotype, allotype male, 
paratypes), Orizaba, April and May, 1922; 8 females, 1 male 
(paratypes), Rio Blanco, collected in April and issuing up to 
May 8, 1922; 1 female (paratype), Nogales, April 7, 1922; 
4 females (paratypes), El Potrero, July and August, 1922. 
Type No. 1099, Hawaiian Sugar Planters’ Experiment Station. 
Coelaspidia new genus. 
Similar in some respects to both Chrysoplatycerus Ashmead 
and Zarhopalus Ashmead, but differing in many details. The 
female differs from either of these genera in being apterous, 
the thorax increasing in width behind the tegulae, the pronotum 
very large, the mesoscutum relatively small, the scutellum lon- 
gitudinally grooved on the disk, the abdomen very large with 
the dorsum very strongly convex at least in life. From Zar- 
hopalus the female differs further in having a broad dorsal
