have adopted ; but I believe it has not hitherto been 

 described. It forms one of a small group of species (the 

 fidva group) from Paraguay, Argentina, etc., having a 

 common facies, the clypeus short and narrowly rounded 

 and entire in front in both ^ and ^, and the last ventral 

 segment in strong contrast to the others, in colour and 

 sculpture. 



P. Championi, n. sp. 



^. Very near io the preceding, but larger, less convex, more 

 oblong, paler, and usually more polished (as if varnished) ; head 

 more finely punctured ; clypeus a little broader in front, with the 

 sides more sinuate, less coarsely but more densely rugose-punctate : 

 sides of thorax less regularly rounded, widest about the middle, 

 thence sinuately narrowed to the base ; the front and hind margins — 

 and margins of scutellum — not at all green ; a distinct dark brown 

 submarginal spot at each side of thorax : elytra still more finely 

 punctured, but the dorsal pimctured striiB more apparent ; on each 

 elytron a somewhat vague — sometimes interrupted — slightly oblique 

 dusky stripe, extending from the shoulder to two-thirds the length 

 of the elytron : pygidium rounded behind : abdomen brilliant dark 

 castaneous without tinge of green, nearly smooth : metasternum 

 entirely punctured, and coarsely but not thickly pilose at the sides : 

 antennjB and legs testaceous, the femora not tinged with green. 



5 . Much larger and more oblong than P. paragiiayends 5 ; the 

 clypeus more prolonged, with the apex more broadly rounded, much 

 more recurved, and the sides more sinuate : sides of thorax not 

 sinuate behind the middle ; a submarginal dark spot, and a small 

 round fovea near its inner side : the elytra much less distinctly 

 punctate-striate, with scarcely a trace of costte or transverse wi'inkling: 

 pygidium much more finely aciculate-rugulose, smoother and punc- 

 tate towards the apex : mesosternal process short, but not so 

 strongly compressed and less vertical in front. 



Long. ^. 24 mm. 9- 26 mm. Lat. ^. 13 mm. ? . 14-5 mm. 



Hah. Argentina (Tucuman). 



I have great pleasure in dedicating this species to my 

 old friend, Mr. G. C. Champion, 



P. ancilla, n. sp. 



(J . Oblong, convex ; head, thorax and scutellum shining reddish- 

 testaceous ; elytra testaceous-yellow, a little less shining than the 

 head and thorax : clypeus short, rounded, entire and reflexed in front,
