The majority of the punctures on the upper-surface are 

 so impressed that there appears to be a minute granule (often 

 semicircular) at the back of each, but the granules are invisible 

 from in front, they are decidedly coarser on some specimens 

 than on others; in some specimens faint indications of elytral 

 striae may be seen, but from others these are entirely absent; 

 the lateral bristles each arise from a small granule. The front 

 claws (fig. 32) are of very different shape to the others (fig. 33), 

 and the difference is apparently not sexual (at least I have 

 been unable to find external indications of sex in the nine 

 specimens under examination) ; its upper-surface is subopaque 

 owing to very fine shagreening. The nine- jointed antennae 

 associate the species with laticollis and helaeoides in Black- 

 burn's table; from which, as from all other described species 

 of the genus, it may be distinguished by the base of the 

 prothorax, this being gently and evenly incurved from each 

 side to the middle ; on all other species the base is gently 

 bisinuate, with the part adjacent to the scutellum in the form 

 of a wide feeble lobe. It is rather more convex than the 

 preceding or following species. 



PSEUDOHETERONYX PUNCTICOLLIS, n. Sp. 



PI. xxvi., fig. 63. 



Black ; antennae, palpi, and parts of tarsi more or less 

 reddish. Upper-surface almost glabrous; under-surface and 

 legs sparsely setose. 



Head with large and rather deep, but not crowded, punc- 

 tures, suddenly becoming crowded on clypeus; the latter with 

 apex gently incurved to middle. Antennae nine-, club three- 

 jointed. Prothorax about thrice as wide as the median length, 

 sides strongly rounded, base very feebly bisinuate, front angles 

 rather strongly produced and acute, hind ones slightly rounded 

 off; median line absent; with large deep punctures, becoming 

 smaller towards sides, somewhat irregularly distributed but 

 nowhere crowded. Elytra with sides gently rounded, apices 

 very feebly rounded (almost truncate) ; with irregular rows of 

 rather large punctures, in wide, shallow striae. Pygidium 

 with very shallow punctures. Front tibiae strongly tridentate ; 

 basal joint of hind tarsi slightly longer than second; all claws 

 acutely appendiculate. Length, 11 mm.

The head and prothorax are opaque, the elytra moderately 

 shining; the whole of the body and even parts of the legs are 

 very finely shagreened. There is a short seta in most of the 

 punctures of the upper-surface, Ibut they are very inconspicu- 

 ous, as they seldom rise to the general level. The hind suture
