Coelioxys philippensis Bingham. 



Ccelioxys philippensis Bingham, Ann. & Mag. Nat. Hist. (1895), VI, 

 16, 439. 



The unusual form of the specific name must be maintained 

 as printed. I examined Bingham's type in the British Museum. 

 Luzon, Laguna, Los Banos and Mount Maquiling {Baker) . 



Coelioxys bakeri Cockerell. 



Coelioxys bakeri Cockerell, Entomologist (1915), 108. 



Mindanao, Iligan, Dapitan, and Davao (from Baker). Type 

 from Iligan. 



Coelioxys bakeri var. atripes var. nov. 



Legs black. Male from Los Banos, Luzon {Baker). 



Coelioxys manilae Ashmead. 



Coelioxys manilse Ashmead, Canadian Entomologist (1904), 36, 281; 

 Cockerell, Proc. U. S. Nat. Mus. (1909), 36, 415. 



Ashmead's description is poor, but I saw his type a number of 

 years ago in Washington and found the last dorsal segment of 

 abdomen to be broadly rounded and obtuse, as in C. bakeri fe- 

 male. Coelioxys bakeri appears to differ from C. manilse by the 

 absence of a fulvous triangle on mesothorax, posteriorly, and the 

 surface of the mesothorax shining between the punctures. The 

 legs of manilse are red, as in typical bakeri. The male of manilse 

 is unknown, but a male from Mount Maquiling, with the surface 

 of mesothorax dull and red tarsi, but the legs otherwise black, 

 is probably referable to manilse; if not, it is a new species, for 

 it is certainly distinct from bakeri. 



Coelioxys genalis Cockerell. 



Coelioxys genalis Cockerell, Entomologist (1916), 49, 157. 

 Originally described from a male from Mount Maquiling. The 

 female (Los Baiios, Baker 6306) is 9 millimeters long; last dorsal 

 segment of abdomen pointed, its apical half sharply keeled; last 

 ventral pointed, notched at sides, extending beyond dorsal. This 

 differs from the European C. elongata in the less-produced and 

 much less parallel-sided last ventral. A female from Davao, 

 Mindanao, is not separable. From Negros I have only a male, 

 and it is separable from a Mount Maquiling male as follows: 



Hair bands of abdomen white; superior apical spines farther apart. 



Mount Maquiling form 

 Hair bands of abdomen fulvous; superior apical spines nearer together. 



Negros form. 



Additional material may indicate that the Negros insect is 

 separable.
