xv, i Cockerell: 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 info 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.
