/'. jaliijieiisis is voiy nnicli smaller than either of the preceding species of the genus, 

 and its antenna) lamellae are much shorter in jjroportion than in those species. The clypeus 

 is very lightly concave (practically straight) and has no tubercles except at its lateral 

 extremities. A pair of small frontal tubercles is situated a little behind it, each about a third 

 of the way from the end to the middle line. The frontal and parietal ridges are obsolete. 

 The central tubercle is very large and resembles in form that <jf the two preceding species. 

 The pronotum resembles that of /'. so//(Z»<s. Thcscutellum is strongly punctured near the 

 middle line, especially behind. The mesothoracic episterna have one or two matt areas close 

 to the lower margin, the rest of the .surface being glossy ; they are punctured above and 

 along the anterior margin. The mesosteriium is polished except along the lateral margin.'* 

 where it is dull. The metastermim has hair-bearing punctures only lieside the middle coxae ; 

 the lateral areas are linear and somewhat rough ; the general surface is glossy and 

 uupunctured. The abdominal sterna are slightly roughened in the broad outermost parts of 

 the scars only. The elytra are somewhat coarsely punctured in the grooves.

The antennal lamellae are moderately long, being about ecpial to three of the immediately 

 preceding joints in length. The labrum is parallel-sided, and is strongly concave in front. 

 The cly])eus is very lightly convex (practically straight) ; it bears an obscure tubercle at 

 either end, and just behind and on the inner side of these tubercles is a pair of small frontal 

 tubercles, which the obsolete frontal ridges do not clearly reach. The central tubercle is very 

 large, it is massive and rounded at the base, but the long forwardly directed apex is 

 somewhat slender. The ])nrietal ii(l<j;es arc obsolete. The pronotum bears only a few fine 

 hair-bearing punctures below the scars ; the strongly impressed median groove scarcely 

 reaches the anterior margin. The scutellum is strongly punctured on either side of the 

 middle line, especially behind. The mesothoracic episterna are punctured above and in 

 front ; they are glossy except for an extensive matt band, which extends downwards from a 

 little above the posterior angle of each towards the ventral angle. The mesosternum is 

 polished except in the .scars, which are dee]) and narrow. The metastennmi resembles 

 that of Psciidiirriiit/iiis jdhipoisis. The abdominal sterna are smooth. The elytra are 

 somewhat coarsely puiK lured aliovc. very coarsely punctured at the sides; the last 

 three ribs al)ove the margin are finely ]>uiutured and hairy.
