 The legs entirely black. Wings with three cubital cells,

Head closely and evenly punctured, that on thorax and 

 abdomen shallower ; malar space very short, impunctate,

 " Matang," iii. 1904, co-types. The last-mentioned specimen 

 in the Sarawak Museum. 



The receipt of more material has enabled me to describe 

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

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

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

 X. coJlaris, Lep., from which, however, it can be readily 

 distinguished by the colour of the pubescence.

A careful examination of the types convinces me that these 

 two are co-specific, B. hreviceps 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 Cliusan. 



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

 Japan, and B. opulentus. Smith, from N. China, both some- 

 what similar in appearance, have been misunderstood by 

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

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

 doubtless on the authority of Handlirsch (Ann. Naturh. 

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

 synonymous with B. hreviceps (1. c). 



These species may be separated by tlie following cha- 

 racters : they are all richly clothed witli bright golden-
