I set everywhere with punctures of medium size. The occiput 
e dorsum of the thorax with a few scattered appressed hairs, 
mt of the head is vertically grooved for the long first joints 
(antennae. Eyes pale red, mouth parts brown. The antennae 
Dut as long as the head and the thorax, thirteen-jointed, the

The first joint is about equal in length to the four follow- 
le third short, that and fourth together shorter than the 
and about equal to the fifth, the joints widening from the

), the following joints to the eleventh of about equal diameter, 
tapering rapidly, the last three not being clearly distin- 
1. The first joint is nearly smooth, the second somewhat 
all the others black-pubescent, each with a transverse ring of 
ppressed yellow bristles. 
meso-scutellum is broadly rounded behind, the sides with an 
ar excavation, the meta-scutellum with an elevated margin and 
lent median carina. The sides of the metathorax are densely 
gl with long black hairs. 
gs transparent, veins dusky yellowish, the post-costal and 
Jl of equal length, about two-thirds as long as the costal, 
membrane sparsely pubescent, the veins with a row of stiff, 
(lack hairs. Patagia dusky yellowish. 
legs are pale yellow throughout, except the coxae, which 
the body color. The abdomen is smooth and shining 
; the under sides of the three posterior segments which are

gments being somewhat tinged with brown. 
fcth, 2.5 mm.; head, .95 mm. wide; thorax, .7 mm. by 1.06 mm. 
jintennae, 1.25 mm.; wing, 1.9 mm. 
specimens from which the above description was drawn, were 
ged and were bred June 5, 1884, from flaxseeds and larvae 
Hessian fly, obtained at DuQuoin, in Perry county, July 4, 
/ 
breeding cage from which these specimens emerged yielded 
ler parasites, but, when examined, were found to contain 
pupa cases punctured as if for the escape of parasitic Al¬ 
together with a few containing dried up larvae.

(Plate IV. Fig. 2.) 
er this head I describe, with some hesitancy, several speci- 
whose generic relations it is difficult to make out, owing to 
:t that all the examples obtained were wingless. The essential 
lance to Pteromalus leads me, however, to place the species 
i that genus. 
| head and thorax a dark bronzed green, and the abdomen 
dark steel-blue. The head is not grooved in front for the 
int of the antennae, but is, like the thorax, thickly punctured
