VIII. Descriptions of twelve new exotic species of the 

 Goleopterous family Pselaphidse. By J. 0. 

 Westwood^ M.A., F.L.S.^ &c. 



[Read 7th March, 1870.] 



The following descriptions of new genera and species of 

 Pselaphidce are offered to the Entomological Society by 

 way of supplement to papers on other species of the same 

 family, published by me in the Transactions of our 

 Society. All the insects here described are exotic, the 

 major part of them having been collected by Messrs. 

 Wallace and Bates. They are of considerable interest, 

 and several of the new genera will render a modification 

 of the existing classification of the family necessary. The 

 singular antennae of Qoniastes, the nearly obsolete palpi 

 of Rliytus, the spinose palpi of 8lntectes, the Pselaphoid 

 palpi of Phalepsns, the rostrate head of Curculwnellus, 

 and the curious coronate heads of the two species which 

 I have assigned to the old genus Bryaxis, especially 

 merit attention.
