Habitat.— Chittagong Hill Tracts. 



Tree Attacked. — Mahogany {Swictenia iiiahogani, Linn.). Kaptai. 



Beetle. -J Resembles the Japanese S. )nikado in form, but the elytra are relali\ely 

 shorter, not more than one-third longer than the prothorax. Blackish-pitchy, dull, entirely 



covered with hne and extremely dense alutaceous reticulation. 

 Description. Front minutely punctate, with a transverse subnitid impression over 



the mouth, the space between it and the black epistoma brown- 

 testaceous ; antennae brown-testaceous, the club infuscate, obovate-acuminate. Prothorax 

 with the lateral and hind angles prominent and acute, median pore not large, oblong, surface 

 with very close, confluent, longitudinal, strigose punctures, not deep. Elytra scarcely bisinuate 

 at base, lighter along the suture and at the apex, closely shagrecned with traces of striae the 

 punctures of which are not discernible ; interstices from behind the middle with a faint median 

 raised line, the first, third, and fifth on the declivity with a series of minute tubercles ; declivitv 

 convex, with short, erect, yellowish pubescence. Under-side piceous, lighter in places, with 

 coarse, shallow punctuation ; anterior legs piceo-ferruginous, the middle and posterior legs 

 brown-testaceous. Length, 3 mm. 



I can trace very little about the life history of this insect. Specimens 

 were evidently sent to the Indian Museum b\- the 



Life History. Chittagong Divisional Forest Officer, presumably from 



Kaptai, where, amongst other exotics, there is a planta- 

 tion of mahogany, the only one, 1 think, existing at that time in the 

 district. They were said to be destructive to mahogany-trees in company 

 with Xylebonis o-ravidiis (p. 586). Although I examined the trees several 

 times whilst I held charge of the Chittagong Division, I was never fortu- 

 nate enough to secure any individuals of this insect. The specimen or 

 specimens sent to the Indian Museum were forwarded with a collection 

 of Bostr\'chidae to M. Lesne at the Paris Museum, and bv him sent to 

 Mr. Blandford.
