5. Pseudochalcothea Staudingerij Vanderpoll. 



This very interesting species, almost similar in colour to 

 P. 'pomacea (Bates), but a little darker, is smaller than the 

 latter, measuring only 25 millim. The middle of the prothorax 

 is punctured, the strigulose area at the sides of the elytra is 

 large, the process of the mesosternum short. The chief 

 character of the species is the process of the posterior tibia? 

 of the male scarcely extending beyond the tip of the tibia, 

 strongly dilated at the apex, with the tip somewhat emar- 

 ginate.

This species very much resembles E. sumatrensis^ Waterh., 

 both having the spots of the elytra very small, and may be 

 only a Bornean form of E. Temmincki^ Latr. 



The male has a very feeble carina on the head in front of 

 the insertion of the antennee. The prothorax, usually more 

 slender and less rounded than in E. Temminchiy Latr., is 

 finely and sparsely granulate, chiefly so in large males. The 

 spots of the elytra are arranged as in E. Temminchi^ Latr., 

 — one at the base, occupying only the third interstice, 

 elongate ; a second, very small, at the base of the fifth inter- 

 stice ; a third near the suture in front of the middle, almost 

 as broad as long, occupying the third and fourth interstices ; 

 a small elongate spot on the fifth and one spot on the 

 eighth and ninth interstices, both behind the shoulders ; a 

 postmedian macula on the third to the fifth and two elongate 

 anteapical spots on the third and on the ninth interstices, all 

 these spots coloured as in E. Temmincki, Latr. The sutural 

 stripe of the elytra is smooth, the second punctulated in the 

 middle ; the punctures of the other stripes are large, with the 

 interstices between them somewhat elevate ; the biggest male 

 has the punctures of the fifth to the eighth rows relatively 

 not so large as they are in smaller specimens.

Varies very much in size, like E. Temminchi, Latr.
