twice as broad as the greatest length. Anteunse about as 

 long as the head, thorax, and median segment combined^ the 

 second joint of the flagellum as long as the first and third 

 combined ; the frontal prominence at the base of the 

 anteuuie very slightly developed. Eyes separated on the 

 vertex by a distance equal to tlie length of the second joint 

 of the flagellum plus two-thirds of the third joint ; the 

 ocelli in an equilateral triangle, the posterior pair much 

 further from the eyes than from each other. Pronotum 

 very widely arched posteriorly, without an angle in the 

 middle. Median segment slightly convex, with a median 

 groove from the base, becoming less distinct towards the 

 apex, broader at the base than longj narrower at the apex, 

 more opaque than the thorax and with a little short whitish 

 pubescence at the angles. Petiole of the first abdominal 

 segment very short, occupying less than one-quarter of the 

 total length of the segment, which is no longer than the 

 second segment ; sixth dorsal segment punctured sparsely at 

 the base, smooth and narrowly rounded at the apex ; the 

 abdomen opaque and slightly pruinose. Second abscissa of 

 the radius distinctly shorter than the third, scarcely longer 

 than the second transverse cubital nervure ; first recurrent 

 ncrvure received a little before the middle of the second 

 cubital cell, second before one-qitarter from the base of the 

 third cubital cell. Submedian cell a little longer than the 

 median ; cubitus of the hind wing originating just beyond 

 the transverse median nervure. Cubitus of the fore wing 

 reaching beyond the third cubital cell, more than halfway 

 to the outer margin of the wing. An irregular fuscous band 

 along the basal nervure, another filling the second cubital 

 cell and extending to the base of the radial and apex of the 

 discoidal cell.
