received just beyond the second transverse cubital ncrvure ; 

 the transverse nervure of tlie humoral cell very long and 

 strongly oblique.

This belongs to the section of the genus in which the cubi- 

 teUan and discoidellan cells are not closed, the intercubitelhi 

 and recurrentella being absent. The truncate clypeus and 

 the loiiirthencd hind coxc'e are unusual in the genus. In the 

 I'onner character it resembles T.riifohalteatus^ Cam., described 

 as a Siobla, which seems to be its nearest relation.

$ . Testacea ; anteniiis articulis 2-4, mandibulis apice, femnribus 

 posticis, tibiis posticis apice, tarsis posticis, nmcula(mo inter 

 ocellos nigris ; tergitis 5-7 in uiedio infuscalis; alls flavo-

Long. 10 mm. 



?. Mandibles broad, bidentato ; clypeus short, minutely 

 punctured, very feebly emarginate at the apex, almost trans- 

 verse. Head closely and rather strongly punctured, not 

 narrowed behind the eyes ; vertical area a little broader than 

 long, the lateral grooves well defined. Antennfe tapering to 

 ihe apex, densely clothed with short hairs, the third and 

 fourth joints subequal. Pubescence of the head and thorax 

 blackisli. Thorax sparsely and finely punctured, much more 

 closely and coarsely on the mesopleura3 than on the dorsal 

 surface. Abdomeji smooth and shining. Hind metatarsus 

 distinctly less than twice as long as the four apical joints of 

 the hind tarsus combined, the fourth joint asymmetrical, 

 scarcely half as long as the third ; tarsal ungues bifid. Hind 

 wing with a closed median cell, but without a closed cubital 

 cell. The basal nervure of the fore wing reaches the costaat 

 the point of origin of the cubitus.
