COLYDIIDAl':. 97 



Antennae nearly glabrous, the broad biarticulate club, however, is 

 distinctly pubescent; 2nd joint stout and as large as the visible portion 

 of the basal; 3rd slender, nearly twice as long as broad; 4th and otli 

 similar in form but rather shorter; joints 6-9 short and bead-like, the 

 last slightly larger than the 8th; 10th abruptly enlarged, thrice as 

 wide as the 9th; the terminal large, obtusely rounded. 



In ;V. hrevis, 1353, all the ventral segments are granulate; it is 

 also different in other respects. N . detnissus, 3224, has the sides of the 

 tliorax flatter, and its central lobe is narrow, quite cylindrical indeed, 

 and widely separated, right to its base, from the others; the elytra 

 are narrower at the base, and have distinct serial sculpture, cVc. 



Length, 2 mm. ; breadth, 1 mm.

 Coleopt., p. 1085. 



Elongate-oblong, transversely convex, without nodosities, opaque ; it 

 seems nude, the flavescent setae being hardly discernible; fusco-piceous, 

 faintly rufescent on some parts, antennae and legs infuscate red. 



Head distinctly granulate behind but obsoletely on the flat forehead ; 

 labrum prominent, pitchy-ied, almost smooth and shining, with a 

 transverse series of minute setigerous punctures in front. Thorax 

 slightly broader than long, its sides gently curved and somewhat flattened 

 to beyond the middle, not perceptibly crenulate; base and apex strongly 

 medially rounded, and sinuate near the sides, the posterior angles thick 

 and directed backwards ; its surface only a little uneven, having a 

 shallow median impression, another near each side, and a pair of obscure 

 basal elevations; it is covered Avith distinct though somewhat flattened 

 granules. Elytra incurved at the base, no broader than the thorax, just 

 double its length, gradually narrowed posteriorly; the granules are 

 nearly quite seriate, and usually rathei- longer than broad; there is a 

 slight basal elevation midway between the suture and each shoulder, but 

 there are none along the disc. 



Antennae rather short, 11-articulate; basal joint almost Avholly ex- 

 posed, 2nd neai'ly as thick but rather shorter, the next evidently longer 

 than the 4th, joints 5-9 monilifoi-m and small; club broad, biarticulate. 

 Tibiae straight, with short slender setae. 



Distinguishable from //. riiditi, 1935, hy the less uneven, simply 

 luargined thorax; by the more slender gi'anulation, and entii'e absence 

 of irregularly raised series on the elytra.; and by the distinct granular 

 sculpture of the back part of the head, &c. 



Length, 3A^ mm. ; breadth, 1 J mm.

I'neven, convex, oblong, shining, sjiaringly elad with pale slender 

 setae which are most easily seen on the elytral nodosities; head and 

 thorax piceous, the front and sides of the latter rufous; elytra fusco- 

 testaceous, their sides, the middle of the intci-stices, and a conspicuous 

 ^pot just below the summit of tlie apical declivity dark fuscous, the
