Length 11 — 19 millim. — Black. Elytra very slightly widened 

 behind in the $ . Forehead slightly depressed. Frontal clypeal suture 

 quite distinct in the middle. Dorsal punctuation of the elytra very 

 dense and large. The marginal groove of the elytra gradually thins 

 out behind. 



$. Forehead smooth and shining in the middle, punctate on 

 the sides and on the anterior edge. Epistome finely punciuate. 

 Prothoracic horns parallel, curved downwards at a right angle. Pos- 

 terior angles of the prothorax granulated. Scutellum shining, tuber- 

 cular, with a few deeply marked pits. The dorsal pits on the elytra 

 reniform in shape. Apical declivity of the elytra slightly concave, 

 less densely puncuate than the dorsal portions, the punctuation thin- 

 ning out below. Suture slightly prominent on the declivity. Abdomen 

 densely punctuate and densely and finely pubescent. Posterior tarsi 

 with long hair, their joints 2 and 5 sub-equal. 



? Body longer than that of the <J • The middle of the forehead 

 has a fine and scattered punctuation, rasp-like except right in the 

 centre, where it is smooth. Apical declivity of the elytra not concave, 

 at least as densely punctuate on its upper half as the dorsal area of 

 the elytra ; lateral callosity of the elytra hardly indicated, the lower 

 borderless thick than in the <J. Posterior tarsi without long hairs, 

 their second joint distinctly longer than the last. Transitional forms 

 between the heteromorphous and the homeomorphous $ occur, but 

 they appear to be rare. The eyes are smaller in the S than in the 

 9 ; their size varies greatly in the latter sex. 



Distribution. — Lesne gives the whole of Australia as the habitat. 

 Specimens, however, which I procured in Chota Nagpur in 1897 were 

 identified for me as this species by Mr. Walter F. Blandford in that 

 year. Therefore I add — India. — Chota Nagpur (Singbhum). 1 

 Coll. Ind. Mus. Ca/c, etc, unrepresented. 



Life-History. — Little is known on this subject. The writer 

 found the insect boring into the posts and rafters of Sal (Shorea 

 robusta) in newly constructed forest rest houses in Chota Nagpur 

 between March and June 1897. The 5 bore into the wood and 

 oviposit there. 1 Lesne states that this is the insect of which Nordlin- 



1 In the face of a recently received letter from Mr, Lesne in which he says 

 that he has never seen or heard of other specimens of this species from India 

 endeavours will be made to procure my original specimens for submissal to him.
