ART. 4 NEW PARASITIC HYMENOPTEEA — GAHAN 17 



coarser cilia extending obliquely inward and backward from the 

 marginal vein and partially dividing the hairless streak into anterior 

 and posterior areas; abdomen (in dead specimens) very short and sub- 

 triangular, about half as long as thorax, finely shagreened above, the 

 vibrissae rather short; ovipositor not exserted. Apex of scape, first 

 and second flagellar joints and entire club pale yellow or nearly 

 white, rest of antenna black; head dull black, the frons with a very 

 faint metallic tinge; thorax mostly dull black but with the mesoscu- 

 tum metallic greenish and the scutoUum bronze, the polished portion 

 of latter with more metallic greenish reflections; abdomen black with 

 shght metalhc tinge above; leg black; all trochanters, narrow basal 

 band and broader apical band on all tibiae and all tarsi pale yellow- 

 ish; wings hyaline or with only a very faint fuscous tinge, venation 

 dark brown. 



Male unknown. 



Type locality. — Sixola Valley, Province of Liraon, Costa Rica. 



Type— C&t. No. 29443, U.S.N.M. 



Described from 12 female specimens received from F. R. Swift, 

 Almirante, Panama Republic, and reared by him from eggs of Hem- 

 iceras rara collected in Sixola Valley, Costa Rica.

The type of this species should be in the British Museum. A par- 

 atype specimen in the United States National Museum has been 

 mounted on a slide by Girault and is in poor condition. In the col- 

 lection, however, are nine female specimens determined by Girault 

 as Encyrtus submetallicus after comparison ^vith this paratypo. These 

 were reared from eggs of the hemipteron, Nezara viridula, collected 

 on the island of St. Vincent, West Indies, and were sent in by F.. 

 Watts. They agree with what is left of the paratype as well as with; 

 Howard's description and seem to be correctly determined. 



The species belongs in the genus Ooencyrtus Ashmead. In color 

 markings it is quite similar to moneilemae Gahan but differs from 

 that species by having the frons distinctly narrower, the mesoscutum 

 and scutellum more distinctly sculptured and the forewings some- 

 what narrower. It may be distinguished from the other American 

 species by the entirely pale testaceous legs.
