British Braconidx. 9 



differs in the important structure of the abdomen. Form 

 elongate, subcylindric. Head subcubic ; vertex almost 

 plane ; front depressed ; occiput deeply excavated, not 

 margined ; clypeus broad, transverse, elevated, separated 

 from the face by a deep suture ; mandibles quadridentate, 

 one of the median teeth being the largest : maxillary palpi 

 6-, labial 4-jointed, one half shorter than the maxillary ; 

 eyes glabrous. Antennae ^ shorter than the body, those 

 of the $ rather longer, multiarticulate. Prothorax very 

 short ; mesothorax and scutellum finely but sparingly 

 punctulate ; mesothoracic furrows wide and deep, converg- 

 ing to a broad fovea before the scutellum ; furrow of the 

 mesopleurse broad, crenulate, united anteriorly to a second 

 furrow, obliquely placed near the insertion of the wings : 

 metathorax rugose, irregularly and often indistinctly 

 canaliculate in the middle longitudinally. Stigma lan- 

 ceolate, emitting the radial nervure somewhat beyond 

 the middle ; radial areolet lanceolate, remote from the tip 

 of the wing ; radial nervure faintly sinuated before the 

 extremity; recurrent nervure distinctly rejected. Abdomen 

 sessile, depressed, as long as the rest of the body, or longer, 

 striolate from the base to beyond the middle of the 3rd 

 segment, moderately compressed at the apex in the $ ; 

 1st segment nearly as wide as the metathorax, very little 

 contracted at the base ; 2nd suture well marked. Terebra 

 hardly exserted. Description slightly abridged from 

 Giraud. 



Only two species of Polemon are known, P. lipars& and 

 P. melas, Giraud, the second of which is suspected of 

 being a melanic variety of the first. A third species has 

 been described by Van Vollenhoven as P. albiiiianus ; this 

 however has not the sessile abdomen and striolate seg- 

 ments of Polemon, and manifestly belongs to Gcelinius.

5 Black ; middle of the abdomen rufous. Head pubescent, rather 

 wider than the thorax, punctate on the face, and sides of the vertex, 

 more vaguely above ; clypeus very short, more or less sinuate on the 

 anterior margin ; palpi testaceous, the two first joints of the
