1268 COLEOPTEHA 



a rather slender elongate club, tenth longer than broad, eleventh 

 nearly twice as long as tenth. TJiotclv very short, obtusely pro- 

 duced in front at the middle ; its carina distant from the base, 

 angulated towards the scutellum, with two njore or less evident 

 sinuosities on either side, bent forwards and extending along nearly 

 two-thirds of the side, thus forming a nearly rectangular angle. 

 Scutellum small, subquadrate. Elytra oblong, shoulders obtusely 

 rectangular, rather wider than thorax, perpendicular and broadly 

 rounded behind, uneven above. Pygidium curviliuearly triangular. 

 Legs moderate, the anterior longest, femora clavate. Tarsi elongate, 

 narrow, their first joint nearly twdce the length of the second, third 

 very short and bilobed ; claws toothed. The mesosternal process 

 small, broadly angulated behind. 



Fem. Head and rostrum of normal size, about equal in breadth. 

 AntcnncB as long, or nearly as long, as the body, the club moderately 

 short. Eyes quite uncovered. 



2234. P. signatus, "••'>'• Convex, blackish, densely covered 

 with blackish, pale-brown, and grej'ish hairs; the last predominate 

 on the head, rostrum, thorax, and sides of elytra; the first form two 

 basal spots on thorax, four minute ones in a transverse series behind 

 the middle of elytra, two of which are on the suture, and, on each 

 elytron, a large, oblique, vitta-like mark extending from the suture, 

 before the middle, towards the outer extremity ; the infuscate pubes- 

 cence is most conspicuous on the elytral disc ; shoulders obscure- 

 green, as are also the variegate legs, tarsi blackish, antennae pale- 

 brown, their basal joint and club darker. 



Bostmm as broad as the head, subquadrate, slightly raised and 

 angulate at anteunal cavity ; apex medially incurved, obliquely sinu- 

 ous towards the sides ; the sculpture quite concealed. Mandibles 

 large, castaneous, tipped with black. Eyes contiguous with thorax, 

 transverse, deeply emarginate, more prominent and pointed below 

 than above. Antennce, slender, shorter than the body, basal articula- 

 tion moderate ; second very short, fourth rather longer than third ; 

 joints 3-8 gradually widened towards the extremity ; ninth slightly 

 longer than eleventh, very slender at base; the club densely, the 

 other joints more sparingly, pubescent. Thorax strongly transverse, 

 obtusely rounded in front, rather closely and finely punctate, uneven, 

 there is a smooth, shining spot on the middle, but the sculpture can 

 hardly be seen ; the carina bisinuate towards each side, the middle 

 angulate, forming subacute angles, and extending nearly half-way 

 along the sides. Scutellum pilose, with a smooth line along the 

 middle. Elytra rather broader than thorax at base, oblong, with 

 two large prominences near the base, the third and fifth interstices 

 terminate in elevations ; their serial punctures or striae more or less 

 flexuous. 



I feel quite satisfied that this is a distinct species ; my specimen, 

 a female, is nearly twice the bulk of No. 939, the description of 

 which was derived from a male. The sinuation of the carina just 

 beyond the middle is about twice as wide as it is in P. vieinert^-
