HYMENOPTERA PARASITICA 337 



shining, closer and more strongly punctate, the scutellum convexly elevated, nearly 

 smooth, the postscutellum smooth, impunctate, but with two foveolae, the posterior face 

 of the metathorax polished, impunctate, but with some faint, transverse aciculations 

 towards sides, towards the base and the pleura strongly punctate. Mandibles toward 

 base and the anterior femora beneath and toward apex, their tibiae and tips of tarsal 

 joints rufous ; rest of legs black. The head is transverse, thin antero-posteriorly, the 

 temples being flat, not developed, the face above the insertion of the antennae concave, 

 the basin being smooth, except some faint aciculations or wrinkles ; below the antennae 

 the face is feebly convex, sparsely punctate but shining ; the clypeus is large, smooth, 

 the labrum slightly exposed, yellowish ; palpi yellowish ; ocelli pale. The wings are 

 hyaline, with a small black spot almost at the extreme apex of the front wings, the 

 stigma and veins black, except the longitudinal veins at their origin, which are testaceous. 

 The abdomen is similar to that in Pimpla (sens, str.), the dorsal segments 2 to 6 with a 

 transverse impressed line at apex, which is more or less obsolete medially, and with 

 segments 2 to 5 also with an oblique line on each side extending from the base to the 

 apical transverse line, the apical portion of the segments beyond this line being smooth. 



?. Length 7 to 14 mm. Agrees in every respect with the female, except that it 

 is smoother, feebly, sparsely punctate, the antennae longer, the abdomen elongate, 

 slender, the first and second segments polished, impunctate, while the following 

 segments are also polished but with some sparse, feeble punctures.

This species has been bred by Mr Albert Koebele from a geometrid larva infesting 

 cocoanut palms, identified by Dr H. G. Dyar as Omiodes blackbiirni Butler.

I. Length 8 mm. " This species differs from E. uiacnlipennis as follows : — The 

 face is entirely yellow, the eyes are narrowly bordered with yellow except at the top, 

 the scape beneath, and the anterior coxae and trochanters, the basal half of the scutellum, 

 and the postscutellum are yellow ; the wings are much darker tinted, the nervures and 

 stigma are quite black ; the metanotum is more strongly punctured, and the oblong 

 depression found near the base in E. maculipennis is absent ; the punctuation on the 

 abdomen is stronger, there being also a distinct punctuation on the second segment, and 

 the transverse impressions are more conspicuous. Possibly an examination of a large
