Hah. Brazil: Rio de Janeiro. 



This is a rather large, slightly metallic species, very 

 distinct from those hitherto described. The elytra are 

 rather drawn out behind, so that the body does not appear 

 broadly rounded there, and the striation is very close and 

 deep. The striae are simple in the anterior part, but 

 become broad and multiple, so that the interstices are 

 narrowed to carinae, upon which are placed scanty hairs at 

 intervals. 



The British Museum collection contains, besides a speci- 

 men taken at Rio de Janeiro by the late Alexander Fry, 

 one from Dej can's collection labelled Adelops striatals, 

 Brazil : Sonmier. It is quite different from Chaetodus 

 sto'iatiis, de Borre.

Hak Malay Peninsula : Perak ( JF. Doherty). 



One specimen of each sex was taken by the collector. 



It is a species extremely close to P. gigas, Arrow, and 

 when describing that species I regarded them as identical. 

 It is a little smaller, and the tarsi are noticeably shorter 

 relatively, at least in the male, in which sex they are a 

 little longer than in the female. The pronotum is rather 

 more densely punctured, less shining, and without a 

 smooth longitudinal line along the middle. Its sides are 

 a little more rounded and very slightly incurved beyond 

 the middle, so that the base is a little narrower than in
