Blackburn's table of Group 4, the punctures of its elytra 

 would associate it with deceptor and sloanei, both of which 

 have the sutural mucros very short (practically absent) and 

 the pygidium non-carinate. The prothorax is not so dark as 

 the rest of the upper-surface, but it is much darker than the 

 antennae. The type has a curious oily appearance. 



Haplonycha novemarticulata, n. sp. 



Rather dark reddish-castaneous and lightly iridescent, 

 antennae much paler. Under-surface and legs rather densely 

 clothed with golden hairs, each lateral gutter of pronotum 

 with a feeble row of hairs ; membranous fringe of elytra long, 

 its greatest length about equal to that of fourth joint of 

 hind tarsi ; pygidium (except at its glabrous tip) with dense, 

 very short and stiff setae. 



Head with moderately dense and coarse punctures, rather 

 denser in middle of base of clypeus than elsewhere; front 

 face of clypeus with numerous punctures, but in middle the 

 setiferous ones confined to a single row. Antennae with third 

 and fourth joints subequal, seventh-ninth forming a compara- 

 tively small club. Maxillary palpi with penultimate joint 

 slightly longer than antepenultimate, and distinctly shorter 

 than apical. Prothorax about thrice as wide as long, sides 

 strongly rounded in middle, thence oblique to apex and 

 arcuate to base, front angles acute and produced, hind ones 

 obtuse and not rounded off ; punctures rather small and 

 sparse. Elytra very feebly dilated to beyond the middle; 

 punctures larger and more numerous than on prothorax, 

 striation feeble ; suture acutely bimucronate. Pygidium 

 finely shagreened, except at tip ; its suture with propygidium 

 marked by a conspicuous, briefly setose, feebly bisinuate 

 ridge. Basal joint of hind tarsi much longer than second. 

 Length, 15|-16| mm.

 River (H. S. Cope). Type, I. 7815. 



In general appearance strikingly close to octoarticulata, 

 but each antenna has nine distinct joints; it also looks like 

 a very small firma, but the prothorax has much smaller 

 punctures, and the apical joint of the palpi is considerably 

 shorter and stouter. The hind angles of the prothorax 

 somewhat resemble those of badia, but the two species are 

 otherwise very different. On dissection the penultimate joint 

 of the palpi is seen to be just a trifle longer than the ante- 

 penultimate, so the species should be referred to Group 4; it 

 is certainly not "much" longer, however, so in the table it 

 should be referred to CC, in which it looks as much out of 

 place as does nobilis ; but if referred to C its elytral punctures
