slightly smaller, with its impressions smaller, the antennae shorter, 

 with the club smaller, and the apex of the last joint less pro- 

 duced; and the second ventral segment regularly convex in 

 middle. 



Macroplectus octofoveatus, n.sp. 



^. Reddish-castaneous, With moderately dense, tine, pale 

 pubescence. 



Head with a round fovea on each side of middle towards base, 

 the fovege open in front, with the impressions connected between 

 antennaj; the interspace somewhat angular. Antennae somewhat 

 shorter than in the preceding species. Prothorax very little wider 

 than head, and about as long, sides about apex rather strongly 

 inflated; each side near base with a large fovea, from each of 

 which a curved line connects with a medio-basal impression, 

 leaving two basal lobes, each of which has a small fovea; median 

 line narrow and deep at base, but not traceable to middle; punc- 

 tures very small. Elytra about as long as wide, each feebly 

 separately rounded at apex, sides very little dilated posteriorly; 

 subsutural stria very distinct, its base commencing in a small 

 fovea; two small fovese on each side representing the base of the 

 dorsal stria, and another small one between these and the one 

 close to suture; punctures numerous and small, but distinct. 

 Upper surface of abdomen with second segment slightly shorter 

 than third, fourth the length of third, but slightly narrower, and 

 slightly longer and wider than fifth; under surface with third 

 slightly shorter than second, and slightly longer than fourth. 

 Metastermivi very feebly impressed in middle. Hind trochanters 

 obtusely dentate. Length 1^-1 J mm. 



9. Differs in having the antennae slightly shorter; metasternum 

 not at all depi'essed in middle, and trochanters unarmed.

In general appearance close to the preceding species, but elytra 

 with eight small basal fovese (a character which will distinguish 

 it from all previously described species of the genus). The
