Xylocopa fuliginata Perez; 1901. 



Mindanao, Dapitan, Iligan, and Davao {Baker) ; Basilan 

 {Baker) ; Luzon, Benguet, Baguio, and Laguna, Mount Maqui- 

 ling {Baker). Probably the commonest species in the Philip- 

 pines. Perez described it from Mindanao and Palawan; the 

 former is to be considered the type locality. 



Xylocopa mimetica Cockerell, 1915. 

 Palawan. 



Xylocopa fallax Maidl, 1912. 



Luzon, Benguet, Baguio {Baker) , 2 males. 



The three following species of Xylocopa have not been seen 

 from the Philippines by me, and their presence there, though 

 reported, requires confirmation: 



Xylocopa dissimilis Lepeletier, 1841. 



Probably the Philippines supposed dissimilis was fallax. 



Xylocopa tranquebarica (Fabricus), 1804. 



This is more generally known as X. rufescens Smith. It is a 

 large ferruginous insect, quite unlike anything I have seen from 

 the Philippines. It has the curious habit of flying at night. 



Xylocopa sonorina Smith, 1874. 



Sunda Island; probably not in the Philippines. The female 

 has the pubescence all black, except on anterior tarsi beneath, 

 where it is ferruginous; wings fuscohyaline, with darker cloud 

 beyond cells, £fnd with bright purple and coppery iridescence.
