MeSOPLATUS DUBIUS, 11. sp. 



J". Reddish-castaneous, elytra slightly paler, appendages still 

 paler. Almost evenly clothed with short white pubescence. 



Head transverse, base distinctly notched; with two rather 

 shallow foveje on each side. Antenna scarcely extending to base 

 of prothorax, second joint fairly large and subglobular, third to 

 eighth short, ninth and tenth larger, distinctly transverse and 

 subequal, eleventh subobpyriform, apex pointed, the length of the 

 three preceding joints combined. Palpi small. Prothorax dis- 

 tinctly wider than head, slightly wider than long, widest at 

 apical third, where the sides are strongly lounded, with a wide 

 and rather deep impression near base, traversed by a median and 

 rather feeble impression, but becoming foveate at the impression, 

 each, side with a large fovea; punctures partially concealed by 

 clothing. Elytra about as long as wide, sides feebly rounded; 

 with eight small basal foveee; dorsal stripe distinct at base, but 

 terminated before basal third; with moderately distinct punctures. 

 Metasternum with a small median fovea and feebly depressed 

 beyond this toJiinder a|)ex. Abdomen with a small medio-apical 

 tubercle on second .segment, the following ones flattened across 

 middle. Legs moderately stout; tibiae feebly inflated near apex, 

 the median pair obtusely spurred at apex itself. Length 1-l^mm. 



9. Differs in having the metasternum scarcely depressed along 

 middle, ventral .segments gently convex in middle, atid the second 

 without a tubercle, the legs somewhat thinner and the antennae 

 slightly shorter, witli the club smaller.

[n general appearance close to several species of Eiipleclops, 

 but second .segment of abdomen of male with a tubercle as in the 

 species of Mesoplatns. It is smaller than M. Edwardsi, not quite 

 so wide, and head differently impressed. The two foveje on the 

 front of the head are feebly connected, and also connected with 

 the others (which are slightly in advance of the eyes), but these 

 are not transversely connected; the pubescence, however, some- 

 what obscures all the impressions.
