Coleoptera collected hy Mr. Pratt on the Upper Yang-tsze, and on 

 the borders of Tibet. Second notice. JoLirney of 1890. 

 By H. W. Bates, F.R.S., F.L.S., &c. 



On his second journey up the Yang-tsze, and through the 

 Province of Sze-chuen to the Tibetan borders at Ta-tsien-lu, 

 Mr. Pratt obtained a collection of Coleoptera, which, though 

 smaller than that of his journey of 1889, includes a considerable 

 number of new and interesting species. The following list is 

 confined to such species as were not mentioned in our former 

 notice in the ' Entomologist ' for July, 1890, and is restricted, 

 as before, to the great tribes Geodephaga, Lamellicornia, and 

 Longicornia. 



Fam. CARABID^. 



Carabus viridifossulatus, Fairmaire, Ann. Soc. Ent. Belg. 



xxxi. p. 91. 



Ta-tsien-lu. Two examples. 



This well-marked and elegant species was described by Fair- 

 maire from examples taken at Moupin. Mr. Pratt's specimens 

 agree with the description, but are rather larger — 33 —36 millim.
