432 Mr. D. Shar^^saescription of a new gcni(s, §'c. 



Osbert Salvin, Esq., in Avhose honour I have named the 

 species. 



Obs. — This species is allied to the Columbian P. rutili- 

 cornis, but is very readily distinguished therefrom by its 

 much shorter head and elytra. In size and form it is 

 extremely similar to the Japanese P. Potoeri, but its black 

 legs and more punctured upper surface separate it decidedly 

 therefrom. 



Osorius mundus, n. sp. Niger, nitidus, antennis pedi- 

 busque rufis; thorace elytrisque parce punctatis, illo linca 

 medio impunctata, minus discreta ; abdomine crcbre punc- 

 tato. Long. corp. 7^ mm. 



Antenna) red, rather longer than the head, the five 

 terminal joints distinctly thicker than the others. Cl}^eus 

 almost straight in fi'ont. Head with coarse punctures, 

 which near the eyes are elevated, the hind portion is with- 

 out punctures, as is also a space along the middle. Thorax 

 about as long as broad, greatly narrowed behind, shining 

 black, with sparing, coarse punctures, which ai'c absent 

 from an indistinct space along the middle. Elytra slightly 

 longer than the thorax, shining black, rather coarsely and 

 sparingly punctured. Hind body rather closely punctured 

 with rough punctures. Legs dark red. 



Two specimens, sent fi-om the city of Mexico by 

 Mr. Flohr. 



Obs. — This species is closely allied to the North 

 American O. latipes, but is more than twice its size.
