202 Major T. Broun on some 



The relatively large cres^ occupying a third of the length 

 o£ each side of the rather short head, the unusual basal 

 sculpture of the elytra, and the short antennfe, all the joints 

 of Avhich except the basal two and the eleventh are tiansverse, 

 indicate a new form intermediate between this genus and 

 Eiipltciojms. Though more like the latter genus in form, 

 its broad head and trisulcate thorax do not accord with 

 typical species, and as there is only a solitary individual, it 

 is not advisable to institute a new genus for its reception.

Nitid, very slightly convex, fulvo-testaceous ; legs and 

 antennae paler, bearing depressed, slender, greyish pubescence. 

 Head as large as the thorax, rounded behind the rather 

 large eyes, with obsolete hind angles, the fovese prolonged 

 and confluent in front, antennal tubercles slightly elevated 

 and distinctly separated. Thorax rather broader than long, 

 a little rounded and widest near the front, obliquely nar- 

 rowed there, very gradually behind ; central channel broad 

 and deep, extending almost from the apex to the base, with 

 a transverse stria uniting it to the lateral foveee, which 

 extend as grooves to the fi'ont. Elytra slightly narrowed 

 before the middle, suboblong, with broad sutural striae ; 

 these are punctiform at the base, with a distinct basal punc- 

 ture alongside each, intra-humeral impi'essions foveiform, 

 rather short and only obsoletely prolonged backwards. Hind 

 body almost as broad as the elytra, but much shorter, its 

 basal segment nearly as long as either of the next two. 

 Legs simple, slender. 



Antenna rather stout, of nearly the same length as the 

 head and thorax, with slender pubescence ; second joint 

 subrotundate and about as large as the exposed portion of 

 the first, third small, slightly narrowed at the base, joints 

 4-8 transversely moniliform, the sixth and eighth just 

 perceptibly smaller than the seventh, ninth and tenth 

 transverse, the former not quite as broad as the other, 

 eleventh conical, not acuminate, nearly equalling the 

 preceding two. 



Less elongate and convex than P. brevicornis, with almost 

 similarly formed antennae, the head rather broader and 

 more curvate behind, the thorax and elytra slightly shorter, 

 the intra-humeral impressions not so deep, and the abdomen
