tudinal impressions, the central one not reaching basal margin ;

Distribution. At present only recorded from Assam. 

 2 . Head with the anteocular and postocular areas subequal in 

 length, depressed anteriorly with the central lobe prominent at 

 apex, the antenniferous tubercles prominent, the postocular area 

 globose both above and beneath ; ocelli very distinct ; antennaa 

 with the first joint shorter than head, shorter than second joint, 

 both these joints moderately curved (remaining joints mutilated in 

 typical specimen) ; rostrum with the first joint much shorter than 

 second, not reaching eyes, a distinct moderately broad collar at 

 base of head ; pronotum with the anterior lobe shorter than the 

 posterior, convexly globose, its lateral margins convex, with a 

 broad central foveate sulcation which does not reach anterior 

 margin and is continued on posterior lobe for about half its length, 

 posterior lobe with three longitudinal punctate impressions, one 

 central and one on each lateral area ; scutellum broad, transverse, 

 not narrowed posteriorly, apical spines wide apart and slightly 

 curved, the lateral margins ridged ; abdomen moderately dilated, 

 the connexivum broadly exposed on each side ; legs robust, the 

 anterior femora incrassate and armed beneath with a short tuber- 

 culous spine on apical area, anterior and intermediate tibiae with 

 a short apical spongy furrow ; membrane not reaching the apical 

 margin. 



Allied to Labidocoris by the spinous anterior femora, but differ- 

 ing from that genus by the distinct structure of the head, first 

 joint of the rostrum much shorter than the second, first joint of 

 antennae shorter than head, &c.

2 . Head, pronotum, and scutellum sanguineous ; first joint of 

 antennas dull reddish, its apex and the whole of second joint black; 

 body beneath shining black ; head beneath, rostrum, prosternum, 

 lateral margins of meso- and metasterna, legs, and lateral margins 

 of abdomen sanguineous, disks of fourth and fifth and nearly the 

 whole of sixth segment dull reddish ; apices of tibiae and marginal
