 tinctly pantherine ; inferior carina of hind femora high and 

 strongly arcuate. 

 d 1 . Markings of tegmina mostly confined to the anterior half or three-

d~. Markings of tegmina crossing them ; apex of axillary field dark; fus- 

 cous band of wings distinct, very broad, not narrowed at the 

 anal vein; hind tibiae red. . . . (X.) latefasciatus. 



c 2 . Median carina of pronotum usually distinct between the anterior and prin- 

 cipal sulci ; markings of the tegmina not pantherine but more or 

 less marmorate, much after the pattern of Trimerotropis ; in- 

 ferior carina of hind femora usually normal, rarely high or 

 strongly arcuate. 

 d 1 . Lateral lobes of pronotum slightly wider below than in the middle by 

 the retroarcuate curve of the hind margin ; inferior carina of 

 hind femora not prominent. 

 e 1 . Band of hind wings broad, leaving not more than two lobes apically 

 free. ........ (A". ) obscurus. 



e 2 . Band of hind wings usually less broad, leaving more than two lobes 

 apically free. ...... (A'.) neglectus. 



d 2 . Lateral lobes of pronotum equal, the hind margin vertical and not 

 retroarcuate ; inferior carina of hind femora more or less promi-

 e 1 . Lower intercalary area of tegmina broad, densely filled with anasto-

 f l . Vertical fastigium shallow with low lateral walls, the frontal fas-

 the head and pronotum. Hind margins of metazona entire ; 

 anal line of tegmina pallid ; axillary vein of tegmina free.

 f 2 . Vertical fastigium deep with high walls, the frontal fastigium 

 deeply impressed, with a constricted connection with the verti- 

 cal fastigium. Antennae of ? shorter than the head and prono-
