100 Mr. G. MeaJe-WalJo on 



This insect, which I have much pleasure in dedicating to 

 M. R. du Buysson, of the Paris Museum, is very similar to 

 B. pusiUus, Kohl, in general appearance, but may be readily 

 distinguished by the absence of yellow markings on the face 

 ^nd clypeus and the totally black tarsi.

Cameron^s species, described from Belize, British Hon- 

 duras, is a typical example of M. labiatus, F.

The yellow marks on the head and mesonotum, by which 

 Cameron says that 7. ornaticeps is easily known, are present 

 in I.Jlavopicta. The type specimen from Borneo varies in 

 no respect from specimens from the Khasia Hills, Burma, 

 Tenasserim, and Sikkim in the National Collection.

1. conservator, described from Dory, New Guinea, is 

 certainly the same species as that described three years later 

 as P. limatula from Mysol, the type of which, preserved in 

 the Oxford University Museum, has been compared with 

 specimens of the former from Smith's own collection, now in 

 the British Museum.
