British Braconide. 519 
mesonotum very small ; furrow of the mesopleure finely traced, 
crenulate. Wings hyaline ; squamula and stigma pale ochreous ; 
nervures brownish, arranged as in the preceding ; hind wings 
narrower, without a transverse nervure. Legs pale :flavo-rufous, 
hind tarsi and tips of hind tibiz scarcely darker. First abdominal 
segment elongate, finely rugulose. Terebra as long as 2 of the ab- 
domen. ¢ Antenne somewhat longer than the body, with the same 
number of joints as those of the @ ; stigma fuscous, Length, 1; 
wings, 24 lin. 
Var. Abdomen entirely pitchy black, concolorous. 
England and Ireland ; the males, according to Haliday, 
more common than the females.

Fourth joint of the antenne shorter than the 3rd. Maxillary 
palpi 6-, labial 3- or 4-jointed. Metathorax not carinated ; furrow 
of the mesopleurze smooth or obsolete. Stigma small, sometimes 
indeterminate at the extremity where it is confounded with the 
metacarp, and sometimes subobsolete; radial areolet ample, cultri- 
form, attaining the tip of the wing; 1st intercubital nervure longer 
than the 2nd abscissa ; Ist cubital areolet separated from the Ist 
discoidal ; 2nd cubital areolet complete, pentagonal; recurrent 
nervure plainly evected; 2nd discoidal areolet imperfectly closed ; 
anal nervure subinterstitial. 'Terebra considerably exserted. 
The small black species of this genus may be recog- 
nized at once by their wings; the 2nd cubital areolet is 
produced angularly to meet the recurrent nervure, thus 
forming a 5th side to the areolet; hence the name of the 
genus. ‘This structure, however, must be considered 
ideal, for the nervures, as usual, lose their colour on 
approaching the anastomosis. ‘The antennz exhibit a 
diminished number of joints, and the labial palpi are 
sometimes triarticulate. 
The species are not easy to tabulate, but perhaps the 
following attempt may conduce to their determination :—
