﻿TWO SOUTH AMERICAN PARASITIC HYMKNOPTERA. 213 



saw specimens of this insect which had heen bred from Harpella 

 fieojroi/ella, but Marshall (Species des Hym. vol. 1, p. 248) gives 

 BostrycJms {Tomicus) hidens as the host. 



A short description may not be out of place : — 



Colour brown or blackish, orbits and clypeus rufotestaceous, 

 mandibles rufotestaceous with the tips blackish. Legs testaceous. 

 Frontal crests distinct, with curved, almost parallel, keels which give 

 the ridges a crenulated appearance when viewed in profile. Antennae 

 blackish, male 19-jointed, female 21-jointed. Thorax punctate, 

 metathorax more finely so. Abdomen rather longer than head and 

 thorax, first segment striolate, more distinctly so in female, the rest 

 smooth and shining. Terebra exserted, somewhat longer than two- 

 thirds of the abdomen. Wings of male clouded with fuscous, the 

 upper with a pale median transverse band, radial and cubital nervures 

 very much thickened, the underwing with a large stigma near the 

 middle of the anterior margin. Wings of female paler, radial and 

 cubital nervures of upper wing not thickened, under wing without a 

 stigma. Occasionally the second transverse cubital nervure is very 

 indistinct in both sexes. Length, male l|-2^ mm., female 2-2^ mm. ; 

 expanse, male 2|— 4 mm., female 4-5 mm. 



Altogether I have examined fourteen specimens, five males 

 and nine females ; the first appeared on April 15th and the last 

 60 recently as June 16th. 



A careful search among the dead twigs, &c., from which the 

 insects were bred has yielded two empty cocoons ; these I found 

 firmly fixed in the burrows of T. hidens; they are thin, white, 

 with no gloss, and very similar in appearance to the cocoons of 

 some of the smaller species of the genus Apanteles. 



NOTES ON TWO SOUTH AMERICAN PARASITIC 

 HYMENOPTERA. 



By a. a. Girault. 



1. Eupelmits koehelei, Ashmead. 



The colorational description is correct but the scape is not 

 mentioned. The pronotum bears a pair of black hair tufts, each 

 somewhat longer and more slender than the one found on the 

 scutellum of Cheiloneurus for instance. Scutellum coarsely scaly, 

 also the triangular portion of the scutum. Elsewhere, very finely 

 scaly. Venter transversely, mesopleurum longitudinally, finely lined. 

 Central white portion of the ovipositor distinctly broader or longer 

 than either black portion. Funicle 1 quadrate, 2-4 subequal, longest, 

 each a little longer than the pedicel, nearly twice longer than wide ; 

 6 quadrate. Scape reddish brown except above at apex. Scutellum 

 not declivous ; caudal scutum glabrous, suffused with brownish, no 

 median ridge. Axillic sculptured like the scutellum, barely separated J
