and there in the longitudinal direction, when the intervals are 

 equal to the diameter of the punctures) ; at rather remote in- 

 tervals very minute punctures may be seen. At the upper part 

 of the posterior declivity, on each elytron, are two short, scarcely 

 noticeable costse ; the extreme apex is slightly reflexed, dull. 

 The first joint of the club of the antennas is a little longer than 

 hroad, the second as long as broad, the third elongate-ovate. 

 The anterior angles of the metasternum, and the metasternal epi- 

 pleura are densely and very finely granular. The abdomen is 

 closely and finely punctured, and very delicately pubescent. The 

 tarsi are not very long as compared with some of the species of this 

 genus.

Pedibis subopacus, n. sp. 



Closely allied to P. (Nyctobates) sulciger, Boisd., but less shining. 

 Entirely black ; the head much more closely and rather more 

 strongly punctured than in P. sulciger, especially on the vertex. 

 Thorax slightly shining only in the middle ; the impression on each 

 side of the middle much less marked than in P. sulciger, the punc- 

 tuation more distinct. Elytra somewhat dull ; the striae nearest to 

 the suture very lightly impressed (except at the extreme apex) ; the
