 1907 Tricentrus fairmairei Dist. Fauna Brit. India 58. 2188. 

 A series of eight of this species without variation in colora- 

 tion or venation. The two males are somewhat smaller than 

 the females. 



III. Tricentrus convergeus Walk. 



1851 Centrotus convergens Walk. List Hom. B. M. 623. 59. 



1870 Tricentrus convergens Stal. Hem. Phil. 728. 1. 



1907 Tricentrus convergens Dist. Fauna Brit. India 53. 



Four specimens, two males and two females, which I deter- 

 mine as convergens. The males are very much smaller than 

 the females and agree well with Walker's description which 

 was founded on the male. The females, however, besides being 

 much larger, are lighter in color and the horns are much more 

 developed and wider apart at their extremities. 



IV. Tricentrus pilinervosus sp. nov. 

 (Figs. 2 and 2a) 



Near Tricoitrus decoratus Dist. but differs in having the 

 horns more elevated and the posterior i^rocess longer, much 

 more acute and extending beyond the posterior angle of the 

 inner margin of the tegmina. 



Entirely black; densely, rather coarsely punctate; covered 

 witli long, silky, scattered grayish hairs. Hairs thicker and 

 matted just below the horns. Horns extending upward, outward 

 and slightly backward ; as seen from above rounded before and 

 almost straight behind. Posterior process very narrow and 

 acute, reaching beyond the angle of the tegmina and bearing 

 a strong median carina which extends anteriorly as far as the 

 horns. Head black, densely punctate and pubescent. Ocelli 

 slightly farther from each other than from the eyes. Eyes 

 yellow. Tegmina fuscous-hyaline, black and punctate at base; 

 costal and apical margin clouded; veins ferruginous and each 

 bearing two rows of short bristly hairs; two discoidal cells. 

 Legs blackish-ferruginous, tibia? pubescent, tarsi lighter. Pos- 

 terior trochanters strongly spined.
