The receipt of more material has enabled me to describe 

 tliis species, which I referred to in an earlier paper (Ann. & 

 Mag. Nat. Hist. (8) xiv. p. 455, 1914). It belongs to 

 Xylocopa sens, str., and appears to be most closely related to 

 A', collarifi, Lep., from which, however, it can be readily 

 distinguished by the colour of the pubescence. 



Subfamily Bombinje.

A careful examination of the types convinces me that these 

 two are co-specific, B. hreciceps being a smaller individual. 

 Smith notes their relationship, but adds, " the form of the 

 head is decisive of their difference." I am unable to find 

 any difference. Both were captured at Chusan. 



These species, together with B. dlversiis, Smith, from 

 Japan, and B. oj^ulentus, Smith, from N. China, both some- 

 what similar in apj)earance, have been misunderstood by 

 recent authorities. In Dalla Torre's Catalogue B. nasutus is 

 given as a synonym of B. mdanurus, Lep. {altaicus, Er.), 

 doubtless on the authority of Handlirsch (Ann. Naturh. 

 Hofmus. iii. p. 213, 1888), and B. opulentus is considered 

 synonymous witii B. brevieeps (1. c). 



These species may be separated by the following cha- 

 racters : they are all richly clotlied witli bright golden-
