 Ehind tessellatus, sp. n. 



Head, prnnotmn, and posterior pronotal process black, tiie 

 latter soniewliur tinted witli castaneons ; body beneath black, 

 le^'S more |)iceou3 brown ; tegniina black, a hirge sjjot in 

 claval area, a similar s|)Ot in radial area, and a broad apical 

 margin castaneous brown, a spot near claval margin, a 

 transverse series before apical area, and a few smaller 

 scattered spots greyisli white; pronotum centrally longi- 

 tndiiially stron<:ly ridged, its anterior lateral angles slightly 

 prominent, not produced, the posterior pronotal process 

 moderately sinuately waved, arched at base where it is 

 separated from the scutellum, and then a little concavely 

 sinuate ai d following the direction of the tegmina, its apex 

 reaching the posterior angle of the inner tegminal margin ; 

 face centrally longitudinally sulcate.

Allied to E. variiis, AValk., but structurally diifering by 

 the much less prominently waved posterior pronotal process; 

 colour-markings also different.

I follow Kohl and Dalla Torre in tiie association of the 

 genera in this group. They aie all distinguished by the 

 incision on the cuter margin of the mandibles and the presence 

 of only one spur on the aj)ex of the intermediate tibife. The 

 recurrent nervures are received by the first and second 

 cubital cells, except in S/'hod>-otes, iw \\\\\c\\ both are received 

 by the second cell. From Pison and its allies the group is 

 distinguished by the entire eyes and the incision of the 

 mandibles; from Xysson by the single spine of the inter- 

 mediate tibia? and the incision of the mandibles. The rela- 

 tionship to Larva is nearer, but the form of the third cubital
