302 On new Ilymenoptera from Northern India. 



covered with a silvery pile ; the tibial and tarsal spines are 

 silvery white. Abdominal segments with silvery bands; 

 the pygidium bare^ shining, and bearing a few scattered 

 punctures. 



This species comes close to T. bengalensis ; it has not 

 the wings clear hyaline, they having a distinct fuscous 

 tinge. In T. bengalensis the second recurrent nervure is 

 received distinctly beyond the middle, in the present species 

 distinctly behind it ; the median segment is not so distinctly 

 reticulated; the basal half is more distinctly longitudinally 

 striated ; and it is a smaller and more slenderly built 

 species. 



Larva apicepennis, sp. n. 



Nigra, mandibulis late rufis, basi metanoti reticulata, apice striolato ; 



alis hyaliuis, apice fumatis. $ . 

 Long. 7 mm. 



Head above the antennse coarsely aciculated, the furrow 

 below the single ocellus deep ; the clypeus shining at the 

 apex, semicircularly depressed above and closely punc- 

 tured ; pro- and mesothorax closely punctured ; scutellum 

 more shining and with the punctures more widely separated. 

 The basal part of the metanotum is closely and finely 

 reticulated, the reticulations becoming finer and closer 

 towards the apex ; the apex has an oblique slope and is 

 finely and closely transversely striated, the striae being much 

 stronger on the apical half ; the middle furrow is deep. 

 Legs black, pruinose, the tibise and tarsi strongly spined. 

 Wings hyaline and iridescent to the base of the stigma, the 

 rest slightly, but distinctly, smoky; the apical abscissa of 

 the radius is oblique and is as long as the top of the first 

 cubital cellule, which is above nearly twice the length of 

 the second ; the upper and middle parts of the third trans- 

 verse cubital nervure have oblique slopes, the lower part 

 is roundly curved. Abdomen pruinose, shining ; the basal 

 third of the pygidial area is smooth, bare, and shining, the 

 rest is closely punctured and covered Avith a rufous pile; 

 the hypopygium is strongly, but not very closely, punctured. 

 The metapleurse are obscurely obliquely striated. 



The wings have a steel-blue reflection in certain lights.
