Classification of the Cokojjterous family Dynastidm. 338 



single female. One specimen was found by Mr. H. E. 

 Andrewes in the hollow stem of a decayed mango tree. 



The species is black, shining and coarsely punctured, 

 the punctures not very numerous on the prothorax, which 

 has a slight longitudinal sulcus at its posterior part, and 

 absent from the scutellum. The elytra bear rows of 

 annulate, moderately-distant punctures and extremely 

 minute punctulations in the interstices. The pygidium 

 is coarsely punctured and the metasternum bears large 

 deep crescentic impressions at the sides and rather fine 

 punctures in the middle, and there are also fine and scanty 

 hairs. 



^. The head is smooth and shining, with a simple 

 slender horn, and the prothorax has a shallow broad ■ 

 impression behind the front margin. 



$ . The head is rugosely punctured and bears a 

 tubercle. 



E. pcrforatus resembles E. platyptcrus, Wiede., but is 

 rather larger and much less densely punctured, especially 

 upon the prothorax, which is sparingly, though very coarsely, 

 punctured and bears a longitudinal impression absent in 

 the other species. The scutellum is without the large 

 punctures present in E. platypterus. The male is most 

 markedly distinguished by the head, which is smooth with 

 a slender horn, while in the older species it is closely 

 punctured and the horn is laterally compressed.

Hah. Ceylon. 



This is a rather broad species, resembling E. pcrforatus, 

 but larger, more closely and still more coarsely punc- 

 tured. The prothorax is closely punctured all over and 

 the punctures become confluent in front. The scutellum 

 is confusedly punctured and the elytra are closely covered
