Head granulate. Thorax broader than long, niueh contracted near 

 the l)ase, with subrectangular posterioi- angles, wliich, liowevei-, are 

 directed backwards; its sides widely explanate aud studded with 

 granules, so that the edges seem irregular!}' serrate, the front projects 

 as far as tiic middle of the eyes; the hinder portion extends outwardly, 

 leaving a deep gap between it and the shoulder, and just in front of it 

 there is an excision, tlieie is also a smaller notch near its middle edge; 

 the disc is distinctly granulate, and has a broad di'i»iession along the 

 middle with iiiegularly elevated latiial borders; at tiie ei'ntie of the 

 base there is a small triangular depression with slightly raised margins; 

 the apex has a pair of moderate elevations, and in the middle is 

 obvicnisly rounded, behind the eyes it is deeply sinuate. Elytra oblong, 

 of the same width as the flattened sides of tlie tlioiax, <juite vertical and 

 rounded behind, with obtusely rectangular shoulders, the lateral margins 

 ai)pear senate; the 4 dorsal sfiies of grannies on each elytron are 

 interrupted by the nodosities, of which there are 3 on the 2nd, the 

 basal is elongate, that on top of the hind declivity is most prominent and 

 projects backwards as well as upwards, the 3rd is placed in front of the 

 last and is smaller; the nodules on the 4th series are smaller, the 1st 

 is situated on the middle instead of being at the base; the lateral 

 sculptuie also is granular, and the shoulders are somewhat nodiform. 



Tibae sliglitly curved externally, and bearing slender, yet distinct, 

 greyish setae. 



Antennae very finely and scantily setose, their basal joint invisible 

 above, 2nd thick, 3rd evidently longer than broad, joints 4—6 slightly 

 longei" tlian broad ami sniiK-wliat obronieal, 7-0 liead-like, the J)th ratlier 

 shorter and broader than thr Sth; club abruptly and considerably 

 enlarged, l)iaiticulate, its basal joint strongly transverse, the terminal 

 rotundate. 



In its natural state it is encrusted with dry sappy matter wliieh 

 conceals tlie real sculptun' and coloration. It then resembles 1167, 

 /'. crassus, more than any otiier species. The specimen described above 

 has been carefully scraped with the point of a needle and cleaned with 

 benzijie, and lias thus been t lansroimed into a beautiful object for 

 micioscopical examination.
