Bhamò; Karin Gheba, alt. 900-1100 m. 



Found throughout India including Ceylon and Assam. The 

 Burmese examples differ from typical specimens from Benson's 

 collection only in the under surface being darker ; the same 

 variety occurs at Hong Kong. 



327. Acanthogenius infuscatus, n. sp. 



A. Bensoni affinissimus; major, palpis an tennis tibiis, tarsis 

 corporeque subtus (ventris apice rufo excepto) fusco-nigris. — 

 Long. 16-18 millim. 



Bhamò. Found also in Assam. 



The difference between this form and A. Bensoni is very 

 slight and it can only be viewed as an imperfectly segregated 

 species. The form of the head (extremely short genae behind 

 the prominent eyes) and thorax (prominent hind angles) and 

 the form of the four yellow spots on the elytra are the same ; 

 as is also the strong punctuation, which on the elytra is bise- 

 riate anteriorly where the interstices are convex, smooth in 

 the middle, and confused posteriorly where they are flat. It is, 

 however, a larger insect and the elytra are relatively longer.
