 two thirds that of the abdomen. 



Differs from the genotype of Coccidoxcnns in that the frons is moderate, not prominent, 

 the scrobes deep, forming a semicircle or nearly; the ]i(istmarginal vein is somewhat shorter than 

 the stigmal and the axilte are a little separated.

 Valves of ovipositor and antenna; black; knees, tips of tibije (more broadly in intermediate' 

 legs being nearly distal half) and the tarsi reddish yellow. Head and thorax very finely scaly 

 and w'ith many scattered, small setigerous punctures; scaliness of scutellum distad with a 

 longitudinal direction or flow. Wings hyaline, the venation dark. Postmarginal vein only 

 about half the length of the stigmal, somewhat longer than the marginal. Mandibles witk 

 the two outer acute teeth longer than the inner. Oblique hairless line of fore wing with about 

 four short lines of discal cilia proximad of it. Hind tibial spurs double. Head with short, 

 stiff white hairs scattered over the surface and which contrast. Pedicel subequal to funicle 2,. 

 funicle ] longest, somewhat over twice longer than wide; other funicle joints each shortening 

 :i little, 6 being subcjuadrate ; club short, not more than somewhat over a third the length of 

 the funicle. Funicle densely clothed. Valves of ovipositor a little compressed. Scutum a. 

 little longer than scutellum. Propodeum and abdomen scaly, the former with an intermediate 

 glabrous portion on each side of meson. I'uiiescence of scutum similar to that of the head but 

 not as conspicuous.
