and twice its length; subcordate; longitudinal canal shallow, not 

 divided into two parts; densely and strongly punctate, especially 

 in middle and at sides of base. Elytra with the 3rd, 5th and 7th 

 interstices I'aised, keel-like and shining; each elytron with nine 

 rather strongh' punctate strife, alternate interstices each with a 

 I'ow of fine punctures, the 5th produced forwards as if to clasp 

 the prothorax, the 3rd and 5th conjoined at apex. Under surface, 

 especially the prosternum, rather strongly punctate ; apical 

 segment of abdomen rather densely punctate, without lateral or 

 apical impressions. Outer side of four anterior tihice with two 

 scarcely visible projections. Length 9, width 2^ mm.

This species may be recognised by its shallow and undivided 

 prothoracic canal, small head, wide eh'tra, and by its prothorax 

 being more heart-shaped than is usual in the genus. In appear- 

 ance, except for the prothorax, it resembles fossus, Newman, or 

 Fascoei, Macleay. 



Deretaphrus puncticollis, n.sp. 



Moderately shining, sides of elytra feebly so; dark reddish- 

 brown; elytra, legs and antennas somewhat paler. 



Head densely and coarsely punctate, punctures encroaching on 

 neck; clypeal suture slightly depressed, marked with depression 

 at sides and middle. Prothorax not much wider at apex than at 

 base ; densely and coarsely punctate, punctures larger than on 

 head, largest about longitudinal canal which is shallow and 

 irregular, and not divided into two distinct parts. Elytra with the 

 3rd, 5th and 7th interstices strongly and narrowly raised or keel- 

 like, the alternate interstices not at all raised and scarcely visibly 

 punctate and appearing merely as interspaces between x'ows of 

 rather strong punctures. Under surface rather strongly punctate, 

 punctures smaller and deeper on pro- than on metasternum. 

 Four anterior tibice. with their outer curve scarcely interrupted by 

 minute projections. Length 8|, width 2 mm.
