the sea). They may be safely kept in this way for a few months, but if 

 subjected to prolonged immersion they are ruined by the marine worm 

 (Teredo nuvalis). To avoid this an experiment was recently made in 

 the dry storage of logs, which has, however, proved unsuccessful, the 

 logs having been attacked by a small beetle which tunnels through the 

 sapwood, penetrating more or less into the heart-wood. The damage 

 done by the borings of this insect is not really very serious, as the 

 tunnels do not as a rule penetrate more than about half an inch into the 

 heart-wood ; but the sapwood is riddled by the borings, and the heart- 

 wood usually shows the holes on its surface, which detract from the appear- 

 ance and market value of the log."

Habitat. Andaman Islands. Also reported from Mysore (R. de la 

 Perraudiere).

 (B. B. Osmaston). 



Beetle. Elongate, somewhat shining, with a scattered short pubescence. Head and 

 prothorax testaceous fuscous, blackish medianly ; elytra piceous black, under-surface piceous 



fuscous, legs testaceous. Head with front closely but deeply punctate. 



Description. Prothorax squarish, anterior angles rounded, posterior ones almost 



straight ; sides and apex but slightly rounded, apical margin tuber- 



culate. Scutellum rounded. Elytra just as wide and nearly twice as long as prothorax, base 

 sub-transverse, humeral angles almost straight, anterior half of sides sub-parallel, thence 

 obliquely incurved, apex strongly acuminate ; punctate-striate, striae feeble, obsolete basally ; 

 punctures small, interstriae sub-convex and shining ; declivity oblique, suture apically elevate : 

 punctures obsolete, interstriae with minute rugosities ; second spine on each side acute. 

 Length, 3.4 mm. 



So far as is at present known this insect would appear to have the 

 same habits as X. adnmbratus described above. Both species were identi- 

 fied by Colonel Winn Sampson. 



XYLOTERUS. 

 This is the first record of a species of Xylotenis from India.
