margins strongly convergent behind, and prolonged into two 

 irregular lateral occipital keels; temporal foveolre shallow, 

 rhomboidal, with rounded angles. Pronotum laterally com- 

 pressed but not constricted ; median keel very well 

 developed, rather thick and distinctly raised, interrupted by 

 the hind sulcus just before the middle ; lateral keels well 

 developed, callous, distinctly convergent towards the first 

 .sulcus and strongly divergent behind it, dee})ly cut by all 

 three sulci, not reaching the hind margin of the pronotum ; 

 fore margin distinctly convex ; hind margin rectangular ; 

 surface of the disc uneven, with rather large impressed 

 points, with callous rugosities between the sulci ; lateral 

 lobes strongly rugulose and punctured, with a callous 

 irregular longitudinal keel in the middle, starting just 

 behind the front margin, slightly sinuate in the middle and 

 almost reaching the hind margin. Elytra extending a little 

 beyond the hind knees; mediastinal area reaching the apex 

 of the basal third, dictinctly dilated beyond its middle, with 

 a false vein; scapular area almost reaching the apex of the 

 elytra, well dilated in the middle and strongly attenuate 

 apically, with sparse oblique veins ; externo-median area 

 narrow, feebly widening towards the apex, with sparse trans- 

 verse reticulation ; discoidal area distinctly shorter than 

 half the whole elytra, scarcely hyaline, with rather scarce 

 but not parallel transverse venules, without a regular false 

 vein ; interulnar area a little broader than the discoidal, 

 sparsely but irregularly reticulated, with a Acry irregular 

 and only partly-developed false vein. Hind femora narrow, 

 with the apical third attenuate. 



General coloration light chocolate-brown. Occiput with 

 two longitudinal rows of brown points. A broad castaneous- 

 black fascia starts from the hind margin of the eyes and 

 runs across the upper half of pronotal lobes ; sides of meso- 

 notum and metanotum also partly black ; the lower jfart of 

 the pronotum lobes pale, with brown punctures, and sharply 

 separated from the dark upper part by the longitudinal keel, 

 which is ivory-coloured ; disc of the pronotum with brown 

 points ; lateral keels and a little interspace between them 

 and the castaneous lateral fascia ivory-coloured. Elytra 

 light fawn ; scapular area with oblique venules partly brown ; 

 discoidal area shining black, with a few hyaline spots in the 

 apical half; three irregular and not sharply-defined brownish 

 spots along the middle of the apical half. Wings hyaline, 

 scarcely iufumate apically. Pectus and abdomen brownish 

 beneath, with brown points ; abdomen of the same colour 

 above, but more strongly dotted with brown. Fore and
