26 Lt.-Col. Winn Sampson—Notes on 
Prothorax subquadrate and shiny, irregularly punctured, 
the anterior and basal portions variolous, the median narrow 
depression gradually broadened and terminating abruptly 
before the centre, and furnished anteriorly on each side with 
small elongate groups of punctures on a depressed shiny 
surface; the base strongly bisinuate and rounded, the entire 
surface sparsely hairy. 
Scutellum absent. 
Elytra twice as long and slightly broader in the apical 
third than the prothorax, the striae composed of a series of 
small closely set depressions surrounded by an edging of 
minute transverse markings, giving the appearance of a 
chain; the first interstice is tuberculate from the base to the 
apex, the third very shiny, with a few very widely separated 
punctures, the base rugose but only slightly broadened, as are 
also the second and fifth; the fourth gradually narrowed and 
ceasing before the base, being replaced by uniseriate tubercles ; 
the declivity commences at the apical third, where all the 
interstices become tuberculate and more densely hairy, the 
terminal depression subtriangular and finely rugose, furnished 
at the upper sutural angle with a blunt spine, caused by the 
convergence and termination of the second, third, and fourth 
interstices ; the outer apical angle is extended into an inwardly 
concave blunt protuberance, formed by the elongation of the 
three last lateral interstices; the sutural angle sharply defined 
but not extended; the abdomen is rugose and hairy, the - 
metasternum being shiny, hairy, and variolous; the gular 
area is also variolous. 
Length 5°25, breadth 1:6 mm. 
Hab. Tonkin, Hoabinh (2. V. de Salvaza). 
?. Very similar to the male, but with two large patches 
of punctures on each side of the prothoracic median line; the 
spine on the upper sutural angle almost obliterated and the 
front quite flat. 
Length 5°25 mm. 
Types of both sexes in the British Museum. 
This species is probably allied to P. b2formis, Chap., but is 
easily separated from it by the sculpture of the elytra, etc.
