Fohjrhaphis Paraenst's, Bates, Ann. & Mag. 'Nat. Hist. 

 May, 1862. — Originally described from Para; found also 

 in Venezuela (Caraccas) . It has the general form of 

 P. papulosa (Oliv.) but is distinguished at once by the 

 absence of the dense clothing of long hairs which distin- 

 guishes papulosa, and the long spiniform tubercles of the 

 elytra. From P. Jansoni (Pascoe) it is distinguished 

 almost solely by colour, being of an ashy tint above, with 

 blackisli-brown clouds on the elytra, and without the 

 lineated appearance of the posterior part, which charac- 

 terizes the ochreous-tawny clothing of P. Jansoni. 



Oreodera glauca, Lin. Syst. Nat. II, 626. — A widely 

 distributed insect. Common on the Amazons and in 

 Guiana. Mr. Belt has sent many specimens from Chon-
