Ilymenoptera from Northern India. 289 



the outer pair converge slightly towards the apex ; the central 

 hardly reaches to the apexj the two bordering it are dis- 

 tinctly separated from it ; the space enclosed by the keels 

 is coarsely aciculated (except at the apex) ; the apex has a 

 sharp oblique slope^ is strongly aciculated^ and covered with 

 a pale down. Propleurse shining ; the upper part smooth, 

 the lower very finely longitudinally striated ; the raised basal 

 edge is impunctate, very smooth, and shining. Mesopleurse 

 shining, sparsely punctured in the middle, and covered with 

 white pubescence. The base of the metapleurse smooth at 

 the base, the rest closely striated. Mesosteruum shining, 

 the basal two thirds sparsely, but distinctly, punctured ; the 

 apex smooth ; the apical area is triangularly narrowed at the 

 base, becoming gradually wider towards the apex ; it is 

 almost opaque, sparsely punctured, and thickly covered with 

 short white hair ; the middle furrow becomes triangularly 

 widened at the apex. The four anterior tarsi and the front 

 tibiae beneath are rufous ; the hair on the four hinder tibiae 

 is silvery ; the spines are rufous ; the calcaria reddish tes- 

 taceous. Wings hyaline, with a fuscous tinge ; the nervures 

 testaceous, the stigma black ; the second transverse cubital 

 nervure is roundly curved outwardly on the upper half; the 

 lower part is straight, oblique. Petiole shining; the sides 

 and apex punctured ; the punctured band on the apex 

 bounded at the base by a furrow ; the apices of the segments 

 are finely punctured and covered with pale hair; the pygidium 

 has the apical half rufous; the middle has a band of long 

 pale hair; the triangular apical part of the basal ventral 

 segment is very smooth, glabrous, and shining; the apex of 

 the hypopygium is testaceous and is covered with long fulvous 

 hair. 



In Bingham's table this species comes into^'B. a^. Median 

 segment with five longitudinal keels. ^' T. lyrata may be 

 separated from it by the apex of tlie petiole being longitudi- 

 nally striated ; the other species of the section {T. flavipennis) 

 is easily known from it by the clypeus having two blunt 

 teeth on tlie apex.
