 and joint 2 markedly constricted in tlie basal half. Prothorax 

 broader than long "(13 : 10), broadest at the base, the sides

 in the latter, the apical margin truncate dorsally and Avithout 

 any postocular lobes ; the upper surface with shallow reticulate 

 punctation throughout. Scutellum subquadrate. _ Ehjtra with 

 the lateral margins not sinuate, the apices almost jointly rounded, 

 the suture not impressed at the base and -without any raised

 brown, the black areas mostlj;' with small naiTow, dark scales, the 

 brown area Avith broader fawn-coloured scales : the prothorax 

 with a pentagonal patch of fawn scales in the middle of the base, 

 not extending outwardly further than stria 2 of the elytra : the 

 fawn patch on the elytra somewhat ill-defined, reaching from 

 the base to beyond the middle and outwardly to about stria 4, 

 though there are a few fawn scales just beyond this, and an 

 indefinite elongate lateral patcli extending from the margin to 

 stria 8 ; the lower surface rather densely and uniformly clothed 

 with yellowish and whitish scales. 



Head with the forehead only slightly narrower than the base 

 of the rosti-um, which arises well beloAV the middle of the eye, its 

 lower surface being on a level with the loAver margin of the eye. 

 Hosti'utn as long as the body, slender, smooth, and almost im-
