with or without a few symmetrically arranged depressions of greater or less distinct- 

 ness, not in contact with lateral areas; lateral areas narrow, parallel sided or nearly 

 so, more or less rugose ; intermediate areas strongly punctured. Posterior parts 

 of hind coxae more or less roughened or punctured. Abdominal sterna finely punctured 

 along anterior margin (often incompletely in the last two segments), and more 

 strongly in a more or less triangular patch of very variable size (sometimes absent 

 from last segment) on each side ; otherwise smooth and polished. Elytra polished 

 throughout; the lateral grooves about as broad as the ridges between them, their 

 punctures extended to form short transverse grooves ; the ninth rib broader than 

 the eighth in part, the tenth broader throughout. 



Habits. — This species is gregarious, it hves under the bark of logs which have 

 rotted till their outer parts have lost their strength.

This variety is not a very distinct one, forms intermediate between it and 

 the typical form being sometimes fo.und. It is represented in the Sarawak Museum 

 collection by a specimen from Matang and another from Kuching — the former is 

 of about the same size as the Andamans and Philippine specimens in the Indian 

 Museum collection (245-29 mm.), but the latter is much smaller than any other 

 specimen I have seen (21 mm.). Mr. Andrewes has sent me for examination specimens 

 from Borneo and Java. 



Description. — Differs from the typical form only in having the frontal ridges of the 

 head normally rising from a short anterior prolongation of the central tubercle ; and 

 especially in the smaller size of the triangular punctured areas of the abdominal 

 sterna, those of the last segment having almost always disappeared.
