downward, its apex lying considerably below the level of the 

 sternum, eyes of moderate size, sessile but strongly prominent, 

 their greatest part laterally projecting beyond apical angles of 

 pronotum, vertex about twice broader than an eye, antenniferous 

 tubercles placed immediately before the eyes, first joint of an- 

 tennae as long as head, passing its apex by two-thirds the length 

 of the joint, second joint subequal to first, third a little shorter, 

 fourth subequal to third, bucculae very short, rostrum reaching 

 a little beyond front coxae, first joint not reaching base of head, 

 half the length of first antennal joint, second joint subequal to 

 first and a little longer than third. Pronotum somewhat con- 

 stricted at the transverse impression, with a distinct depressed 

 apical collar, carinate lateral margins, and the basal margin 

 shortly sublobately depressed in front of corium, but otherwise 

 of different structure in the two sexes ; in the male transversely 

 impressed behind the middle, with the posterior lobe slightly 

 sloping, the anterior lobe but little narrower, globosely convex 

 with its basal part horizontal, the middle part strongly rounded, 

 the apical part perpendicularly declivous, and the lateral margins 

 strongly rounded; in the female transversely impressed in the 

 middle, with the posterior lobe much more sloping, the anterior 

 lobe considerably narrower, forming together with the posterior 

 lobe a continuous, moderately sloping (about 45°), slight con- 

 vexity and with the lateral margins less rounded. Scutellum 

 subequilaterally triangular with a furcate carination, the anterior 

 branches of which are strongly divergent, forming a more or 

 less obtuse angle, straight or hooked at their end. Elytra a 

 little passing apex of abdomen, clavus triseriately punctate, its 

 commissure less than half the length of scutellum, apical margin 

 of corium straight (not "slightly rounded" as described and 

 figured by Distant) , shorter than claval suture, membrane with 

 the two inner veins in their basal half placed close together 

 and rather strongly curved inward, third vein visible only in 

 its apical half, fourth starting from apical angle of corium, 

 forming a very strong curvature inward and in its basal half 

 separated from the second vein by a wide space, fifth vein 

 usually obliterated. Fourth ventral segment with the two sub- 

 lateral glandular spots placed in the anterior part of the segment. 

 Legs simple, front femora not incrassate, unarmed, first joint 

 of hind tarsi as long as the other joints together. 



As Distant has omitted some of the most striking characters 

 of the genus, it has been necessary to redescribe it. The length 

 of the membrane is correctly described by him, but he figures 

 it as not reaching apex of abdomen. The specimen figured by
