and flattened tubercles, with minute granules scattered between,

 ish, oblique, pointed, setiferous, tubercles ; the carina which 

 traverses the epipleuraj tubercled at base and apex, minutely

The following four species of Pterocoma form a distinct group 

 in the genus, distinguished by the third joint of antennse much 

 elongated; prosternum strongly protuberant in front, its process 

 being enormously produced: the elytra having each three (except 

 semicari7iata) costa3, besides the marginal ; and the third unites 

 with the marginal just behind the shoulder. 



Pterocoma tibialis, n. sp. 



Black, somewhat nitid, four hind tibia^ distinctly rufescent: 

 antenna; and legs slender: labrum notched in middle of front 

 margin: head feebly pimctured and pilose: prothorax convex, 

 front angles acute and iirominent: base strongly siniiate, the 

 angles small and outwardly directed: sides feebly rounded; finely 

 sparsely (especially on disc) tuberculate, the tubercles erect, 

 pointed, setiferous: elytra with a depression behind the scutel- 

 lum; first costa continued along the base to scutellum: intervals 

 minutely remotely granulose, and Avith a few long decumbent 

 hairs: epipleura3 finely rugose granulate, the hairs shorter and 

 denser: marginal costa closely set Avith long pointed teeth: pro- 

 sternal process coarsely corrugated. Length 4|-6^ lines.

Pterocoma serrimargo, n. sp. 



Smaller, dull broAvnish-black : four hind tibia? not distinctly 

 rufescent; labrum entire in front: elytra not depressed behind

 from near the base clothed with cinereous pubescence; prosternal 

 process sparsely granulose. Length b^ lines.
