XII, D, 5 Gockerell: Carpenter Bees 347

 posteriorly; wings dark rosy purple (green in chlorina).

brassy dapitanensis Ckll.

The species tabulated are before me. I include some partic- 

 ulars in the following list concerning species that I do not possess : 



Mesotrichia adusta (Perez), 1901. 



Female. Mindanao. Like M. nobilis as to size, and anterior 

 and posterior borders of thorax yellow, but abdomen all black. 

 In M. nobilis, adusta, and occipitalis the abdomen is very hairy, 

 the surface being more or less completely covered. In M. ghi- 

 lianii, which has similar yellow markings, the abdomen is less 

 hairy, so that the surface is visible. 



Mesotrichia amauroptera (Perez), 1901. 



Palawan, Puerto Princesa {Baker), 1 female. 



Mesotrichia bakeriana Cockerell, 1914. 



Luzon, Laguna, Los Baiios, and Mount Maquiling {Baker), 

 females. What I suppose to be the male comes from Mount 

 Maquiling; it resembles M. euchlora, but is smaller and more 

 tawny, not distinctly green. 



Mesotrichia bombiformis (Smith), 1874. 



Luzon, Benguet, Baguio; Laguna, Los Baiios and Mount Ma- 

 quiling (Baker). A large black insect; the wings purple, 

 apically dark greenish. The hairy scutellum at once distin- 

 guishes it from M. latipes. 



Mesotrichia clavicrus (Maidl), 1912. 



Luzon and Ceylon, according to Maidl. Male near volatilis 

 Smith ; hind femora extremely broad. Clypeus reddish yellow.
