Ilymenoptera from Northern India. 200 



of the clypeus almost bare, sparsely punctured. Mandibles 

 black, broadly rufous in the middle and above to near the 

 base ; the latter is thickly covered with golden pubescence ; 

 palpi rufo-testaceous ; the basal joint black at the base. 

 The eyes at the top are separated by the length of the third 

 antennal joint ; the ocellus is round, not dilated before or 

 behind. Thorax thickly covered with long bright hair, 

 which is thickest on the mesonotum. The metasternal area 

 is flat at the base and narrowly keeled in the middle ; the 

 apex has the sides raised, the raised part becoming higher 

 towards the apex, which has a slightly oblique slope; the 

 middle is narrow and deep at the bottom. Legs rufo- 

 testaceous ; the coxae, trochanters, and base of femora are 

 black, which is broadest on the anterior, narrowest on the 

 posterior pair ; the spines are few, stout, and rufous ; there 

 are none on the metatarsus. Wings yellowish hyaline, the 

 apex fuscous ; the first cubital cellule above is about one 

 fourth longer than the second ; the second recurrent nervure 

 is received shortly, but distinctly, beyond the middle ; the 

 second is received the length of the top of the second 

 cubital cellule from the base, the space between the two 

 is a little greater than the length of the first cubital cellule 

 above. Abdomen shining ; the petiole covered with long 

 pale hairs, the pygidium with stiff rufous hairs. 



Comes near to T. fulvopilosa ; may be known from it by 

 the hinder tibise not being so stout, by the metatarsus being 

 more slender and without spines, by the eyes at the top not 

 being so widely separated, and by the different form of the 

 metasternal area.

 and vertex alutaceous, covered with long pale fulvous hair; 

 the hinder ocelli are more distinct than usual and are placed 

 near each other ; there is a narrow furrow in the middle of 

 the vertex. The basal third of the mandibles pallid yellow ;
