This species is parasitic in various Coccids, but I have no 

 doubt that it is ahvays secondary. In- the AsteroJecanium it 

 works undoubtedly on Tomocera calif oriiica Howard and in 

 Saissetia and Coccus it probably parasitizes Microlerys liotin- 

 sl'i/i (Fullaway) and possibly both species of Encyrtus. as well 

 as the Scittellista and Tomocera. 



Coelopencyrtus n. g. 



Female : Head as wide as the thorax, moderately thin fronto-occipi- 

 tally, strongly convex above, the occiput slightly concave with the neck 

 inserted near the center, the face inflexed ; in side view subtriangular. the 

 facial side hardly longer than tlie dorsal, the oral angle truncate ; in 

 frontal view subcircular, the cheeks but slightly converging below, the 

 oral margin broad and slightly produced medially ; frontovertex about 

 two and a half times as long as wide, perceptibly widened at either 

 end and narrowest at the middle ; ocelli in a strongly acute-angled tri- 

 angle, the anterior ocellus at the center of tlie frontovertex, the poste- 

 rior pair almost touching the eye-margins and remote from the occipi- 

 tal margin ; eyes medium-sized, strongly convex and nearly round ex- 

 cept that the posterio-ventral orbits are nearly straight ; cheeks somewhat 

 longer than half the diameter of the eyes ; face about as wide as long, 

 and as long as the eyes, with a nearly semicircular depression forming 

 the scrobes not quite reaching laterally to the lower orbits of the eyes 

 and divided below by a broad, slightly elevated prominence between the 

 antennae. The latter inserted near the oral margin and M^idely separ- 

 ated, rather small and subclavate ; scape slender and moderat^-^bickeHed 

 apically ; pedicel slightly thicker at apex than the following joint and 

 almost as long as the first four funicle joints combined; funicle increas- 

 ing slightly in thickness distad, the first four joints subequal, transverse, 

 the last two about twice as long as the preceding joints and quadrate, 

 the sixth a little larger than the fifth; the three-jointed club large, oval, 

 much broader than the funicle and as long as the four preceding joints 

 combined. Mandibles medium-sized, strongly depijessed, broad at base and 

 with three acute teeth at apex, of which the ventral one is much the 

 longest, the upper one smallest. Maxillary palpi four-jointed, the apical 

 joint slenderly fusiform and nearly as long as the three preceding joints 

 combined; labial palpi two-jointed with the apical joint shorter and slen- 

 derer than the first. 



Thorax rather robust, moderately convex above, the sclerites of the 

 mesonotum lying in one plane ; pronotum short, slightly arcuate ; scutum 

 large, about twice as wide as long; axillae short, transverse, and nearly 

 meeting medially ; scutellum large, broadly rounded at apex, somewhat 

 longer than wide, the disk flattened but the sides and apex highly ele- 

 vated and strongly declivous ; propodeum short at the middle and moder- 

 ately long at the sides. Abdomen somewhat more than half as long and 

 a little wider than the thorax, as wide as long, verv Iiroadly ovate and
