Male. Similar to the female, but the frontovertex is proportionately 
wider, or not quite twice as long as wide, the anterior ocellus placed only 
a little behind the center; antennae slenderer, the club solid; the abdomen

orange-yellow (Ridgway), the frons shading into paler yellow anteriorly; 
the face, underparts of thorax and the legs pale yellowish; antennae pale 
yellowish, but with the fifth funicle joint and base of the club fuscous 
and the remainder of the club yellowish white.

Described from 3 females (holotype and paratypes) reared 
from Pseudococcus brevipes Ckll. (bromeliae of authors) on 
pineapple, Amatlan, Vera Cruz, Mexico, May 20, 1922; 1 male 
(allotype) from the same host on Tillandsia, El Potrero, Vera 
Cruz, July, 1922; and 1 male (paratype) reared November 1, 
1922, from the same host from Cuernavaca, Morelos, Mexico, 
all collected by H. T. Osborn.

Synaspidia new genus. 
This genus appears to be closely allied to the Blepyrus, Aenasius, 
Archinus, and Zaomma group of genera. It differs from Blepyrus, Bury- 
rhopalus and close allies in having the head non-menisciform and without 
large punctures; from dArchinus it differs in having the post-marginal vein 
well developed and longer than the stigmal, the ovipositor not protruded, 
the cheeks not unusually short, ete. From Zaomma it differs in having 
the eyes smaller, the frontovertex only moderately narrowed, the facial 
impression not horseshoe-shaped, the club less strongly enlarged, the pedi- 
cel not very short, the antennae unicolorous, ete. On the whole, it seems 
to agree most closely with Zaomma which, unfortunately, is known to me 
only by desecription.* It agrees with Zaomma in having the face inflexed, 
*T have since examined the type of Zaomma argentipes, which unfor- 
tunately has been badly mutilated, the head being in fragments on a 
slide. Zaomma has the thorax strongly convex above, the axillae rather 
well separated and slightly elevated above the seutellum; the latter is
