the transverse nervure of the humeral cell very long and 
strongly oblique.

This belongs to the section of the genus in which the cubi- 
tellan and discoidellan cells are not closed, the intercubitella 
and recurrentella being absent. The truncate clypeus and 
the lengthened hind coxee are unusual in the genus. In the 
former character it resembles 7. rufobalteatus, Cam., described 
as a Stobla, which seems to be its nearest relation. 
Beleses atrofemoratus, sp. n. 
@. Testacea; antennis articulis 2-4, mandibulis apice, femoribus 
posticis, tibiis posticis apice, tarsis posticis, maculaque inter 
ocellos nigris; tergitis 5-7 in medio infuscatis; alis flavo- 
hyalinis, tertio apicali leviter infuscatis, stigmate basi flavo, apice 
nigro. 
Long. 10 mm. 
9. Mandibles broad, bidentate ; 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. Antenne tapering to 
the apex, densely clothed with short hairs, the third and 
fourth joints subequal. Pubescence of the head and thorax 
blackish.. Thorax sparsely and finely punctured, much more 
closely and coarsely on the mesopleurze than on the dorsal 
surface. Abdomen 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 costa at 
the point of origin of the cubitus.
