2. D. platyrhynchus Nitz. ? Pedic. haematopus, Sco- 

 j)oli ? 



Found on a Hawk, but the species not mentioned. 



Long. T f o poh\ 



I believe this species to be identical with Nitsch's 

 Platyrhynchus^ the P. hcematopus of Scopoli (Ent. Car- 

 niol. p. 382.), as it agrees in alt respects with the latter 

 author's description of that insect, except in wanting the 

 dorsal line on each side of the abdomen. Our specimen 

 very closely resembles that of the Nivmus nisi, in the 

 collection in the British Museum. Nitzsch's insect is 

 stated to have been found on the Falco palumbarius. 



3. D. auritus, Nob. Pedic. auriti, Scop. Var. ? 

 Dilute fulvus : capite triangulari, glabro, nitido, apice 



subobtuso: temporibus rotundatis : abdomine ovato.
