NO. 2105. NEW SPECIES OF HYMENOPTERA—ROHWER. 227 



Female. — Length 8 mm. Eyes large, inner margins broadly emar- 

 ginate, strongly converging toward the clypeus; head shining, except 

 the area between the ocelli and the bases of the antennae, almost 

 impunctate; ocelU in a low triangle; postocellar line twice as long as 

 the ocellocular line; third antennal joint one- third longer than the 

 fourth; notauli well defined; prescutmn with rather close, distinct 

 punctures; the scutum more sparsely punctured; mesepisternum 

 sculptured like the scutum, except the margin, which is striato- 

 punctate; propodeum coarsely reticulate; on the posterior face the 

 reticulations tend to transverse striations; on the dorsal aspect are 

 two well defined carinae, the area between the carinae being trans- 

 versely striate. Black; clypeus, mandibles, face above the dorsal 

 margin of the antennae, scape beneath, cheeks, four anterior legs, and 

 venter yellowish; flagellum beneath, tegulae, posterior legs except the 

 dark apices of the tibiae, and the white four apical joints of the tarsi, 

 first tergite, third and fourth tergites rufous; propodeum posteriorly 

 ruf o-piceous ; wings hyahne, iridescent, venation pale brown, stigma

Family BRACONIDAE. 



Genus APANTELES Forster. 

 APANTELES (APANTELES) SIBINIDIS, new species. 



Apparently is more closely allied to tortricis Ashmead, but the shape 

 of the second dorsal segment and the character of tke propodeum 

 will readily separate it from that species. 



Female. — Length 2 mm.; length of the antennae 1.5 mm. The 

 upper margin of the clypeus well defined; a faint median carina 

 below the antennae; face below the antennae opaque, with some well 

 defined punctures, above the antennae shining, almost impunctate; 

 transfacial fine distinctly but not markedly longer than the facial 

 line; postocellar fine sUghtly shorter than the ocellocular line; intra- 

 oceUar fine subequal with the diameter of the anterior ocellus; 

 antennae 18-jointed, the third joint subequal with the fourth; meso- 

 scutum uniformly punctured, opaque, punctures well defined; suture 

 between the scutum and scutellum finely f o veolate ; scutellum shining, 

 with a few distinct punctures; propodeum with poorly defined cos- 

 tulae, the posterior face reticulate, the dorsal aspect with two sub- 

 convex, shining areas; plate of the first tergite with its length and
