PACIIYTERIA PRYERI. 



Head coarsely punctured on the vertex , behind the eyes 

 and on the cheeks, the vertex with a small smooth space 

 in which the frontal groove ends ; on the antennary tu- 

 bers , which are slightly pubescent and separated by the 

 narrow and deep frontal groove, the punctuation is ex- 

 tremely fine and dense; the clypeus is hollowed, and has 

 raised margins; it is sparsely punctured and provided with 

 a transverse elevation at the middle of the base and with 

 a very distinct keel along the middle; the labrum is very 

 finely punctured , the mandibles nearly impunctate. The 

 antennae are stout, the two first joints slightly rugose in 

 consequence of a dense punctuation , the S^^ — 5th joints 

 densely covered with a jet-black pubescence which gives 

 them a velvety appearance ; the scape is rather short , ob- 

 conical ; the 3rd joint twice as long as the fourth ; the 

 4th_7th slightly increasing in length, the S^^ — 10'^ on 

 the contrary slightly decreasing, the llth of the same 

 length as the 1^^. 



Prothorax distinctly longer than broad at the base, the 

 sides strongly angulated, the angle terminating in a dis- 

 tinct tooth; the anterior and posterior margin strongly 

 upturned , the upper surface and sides transversely and 

 very regularly wrinkled , the intervals provided with a few 

 hair-bearing punctures; along the middle of the raised 

 disk a smooth stripe is present which widens out a little 

 towards the base. The scutellum is elongate triangular, acutely 

 pointed at the tip , smooth and shining with only a few 

 punctures. 



The elytra gradually tapering from the base; the apices 

 separately and rather narrowly rounded , slightly dehiscent ; 

 each elytron provided with two faintly raised longitudinal 

 lines ; the brown basal portion is strongly but not very 

 densely punctured ; the green posterior portion (which is 

 covered with a minute black pubescence) very finely and 

 densely punctured , its outer half opaque. 



The under surface of the head below the mouth irregu- 

 larly wrinkled and pubescent ; the anterior part (collar) of
