xv, i uockerell: Metallic-colored Halictine Bees 13 



stigma piceous; legs black; tarsi reddened apically; abdomen 

 shining, without bands. 



Luzon, Mount Banahao (Baker), two specimens. Very close 

 to H. imuganensis and H. taclobanensis, having the robust form 

 of a female in the male sex. The sexes of H. taclobanensis are 

 colored alike, so I suppose the present insect to be distinct from 

 H. imuganensis, from which it principally differs by being much 

 smaller and quite differently colored. 



The green Halicti of the Philippines fall into two very dif- 

 ferent groups or subgenera; one group consists of H. subpur- 

 pureus and H. pervarians, and the second consists of the other 

 three species. The first is Chloralictus of Robertson ; the second, 

 with males resembling the females, may form a new subgenus 

 Homalictus; type, H. taclobanensis.
