From one pair reared from Pseudococcus on Leucaena glauca and 

 Coffea (Djember, Java). 



Types. — One pair on a tag, the heads and female fore wing on a 

 slide. Cat. No. 19886, U.S.N.M. 



PARECHTHRODRYINUS, new genus. 



Female. — In my table to the earth's ectromine genera of Encyr- 

 tidae runs to EcMJiodryinus Perkins, but differs in that the postmar- 

 ginal vein is half the length of the stigmal, the latter slightly longer 

 than the marginal, which is twice longer than wide. The narrow 

 frons is about three and a half times the diameter of the cephalic 

 oceUus. Ovipositor exserted slightly, white at apex. 



Type of the genus. — Parechthrodryinus convexus, new species, 



PARECHTHRODRYINUS CONVEXUS, new species. 



Female. — Length, 1.65mm. 



Dark metallic purple, the wings hyaline, the legs (except coxae and 

 base of all femora — basal half of cephalic femora) and antennae (except 

 the black club) reddish yeUow, the venation yellowish pallid. Pedi- 

 cel one and a half times longer than wide, slightly longer than funicles 

 1 or 2, the latter subequal, longest, not quite twice longer than wide, 

 6 slightly wider than long ; club somewhat over haH the length of the 

 funicle, conic-ovate, not greatly enlarged but wider than the funicle 

 and distinct; funicle 6 somewhat wider than 1. Cheeks nearly as 

 long as the eyes, the frons with scattered yet distinct punctures. 

 Hairless line of fore wing with about five scattered lines of discal 

 cilia proximad of it, not closed caudad. Axillae broadly joined, with 

 a carina between them. Body finely scaly, densely so, the scutum 

 and scutellum with niraierous, short setae. Abdomen flat-triangular, 

 about as long as the thorax, the latter from lateral aspect much con- 

 vexed. Pronotum transverse-linear. 



The male is about the same except secondary characters and smaller 

 size; its antennal club is solid, the antennae filiform, yellow (scape 

 and globate pedicel brown), the flagellum with scraggly hairs; funicle 

 1 subequal to the club, 3 longer than wide, 6 a half longer than wide. 

 Scape shorter, distinctly compressed. 



From four males, one female reared from a coccid on twigs of De- 

 guelia micropliylla, Assinan, February 2, 1915. 



Types. — Cat. No. 19892, U.S.N.M., a pair on a tag and a shde with 

 heads, fore wings, and a female hind tibia. 



CHEttONEUROMYIA JAVENSIS, new species. 



Female. — Mandibles as in Gheiloneurella hinotativentris Girault, 

 but the so-called second tooth is obtuse, yet a httle larger than the 

 first. Length, 1.10 mm.
