base. Antennae stout; scape somewhat shorter than funicle; 

 first joint of funicle not as long as second and third combined. 

 Prothorax strongly transverse, sides strongly rounded and 

 widest at about basal fourth, with small dense granules. 

 Elytra at base slightly narrower than base of prothorax, 

 sides rather strongly rounded and widest at basal third ; with 

 rows of large partially concealed punctures. Legs stout, four 

 front tibiae denticulate. Length ( ■$ , <j?)> 4J-6J mm. 



O . Differs in having the sides of the prothorax much 

 less rounded, base distinctly wider than apex, elytra wider 

 at the base, the sides less dilated, and their greatest width 

 about the middle.

In general appearance rather close to setosvs, but trans- 

 verse impression at base of rostrum quite distinct before 

 abrasion ; whereas on that species it is normally concealed ; 

 the prothoracic sculpture is also not transversely arranged, as 

 on that species. Before abrasion the elytral striation is dis- 

 tinct, but the punctures appear to be very small and almost 

 absent posteriorly; on abrasion, however, those of the male 

 are seen to be subquadrate, and quite as wide as the inter- 

 stices near the base ; on the female, however, they are some- 

 what smaller. 



POLYPHRADES MARMORATUS, n. Sp. 



Black, antennae and tarsi more or less reddish. Densely 

 clothed with whitish or greyish scales, mottled with pale- 

 brown ; muzzle and under-surface usually with a golden, or 

 silvery, or green lustre, or a rosy flush. Setae depressed and 

 fairly numerous, but not very distinct. 



Head wide, rather convex; with small, dense, concealed 

 punctures. Rostrum very short, narrowed to apex, with a 

 vaguely traceable median line, without a transverse basal 

 impression. Antennae moderately stout; scape shorter than 

 funicle; first joint of funicle slightly longer than second and 

 third combined. Prothorax strongly transverse, sides strongly 

 rounded, base and apex of equal width; with small or 

 moderate, normally concealed punctures, and without 

 granules. Elytra subovate, base the width of base of pro- 

 thorax, widest at about basal third; with rows of normally 

 almost, or quite, concealed punctures. Legs short; front 

 tibiae lightly, the middle pair feebly denticulate. Length, 

 3-3^ mm.
