lineolate; posterior face without a surrounding carina; tegulae testaceous; 

 wings dusky; veins brown, stigma darker, first recurrent almost interstitial ; 

 second transverse cubital and veins beyond very faint ; third cubital almost 

 twice as long as second, hardly narrowed above; legs black, pubescence 

 whitish, tinged with yellowish within, especially on basal joint of hind tarsi; 

 inner hind spur with four teeth; abdomen smooth, polished, almost im- 

 punctate, there being very minute microscopic scattered punctures, thinly 

 clothed with whitish pubescence, forming thin apical bands especially on 

 segments 3 and 4; apical margins 1-4 broadly testaceous. 



Type locality. Bagnio, Luzon, P. I. 



Type. Cat. No. 21361 U. S. N. M. 



Two females received from Col. Wirt Robinson. 



Much smaller and more slender than manilae Ashm., without 

 the abundant ochraceous pubescence of that species and without 

 strong bands of appressed pubescence on bases of segments and on 

 margins of 3 and 4, etc. 



Halictus manilae Ashm. 



Strand's description of his luzonicus exactly fits this species and 

 is probably the same. 



From Baguio, Luzon, three females received from Col. Wirt 

 Robinson. 



Halictus philippinensis Ashm. 



A long series with the above. The propodeal enclosure in this 

 species is peculiar since it is not the triangular enclosure of other 

 species but is formed by the carina surrounding posterior face of 

 propodeum and by carinae running forward from the lateral 

 angles of this carina and it is therefore four sided, with the sides 

 diverging anteriorly. The carina surrounding posterior face is 

 heart shaped. 



Halictus baguionis new species. 



Female. Length over 9 mm. Black, head and thorax with rather 

 abundant long, strongly ochraceous pubescence; punctures of head strong, 

 crowded, below antennae, rugoso-punctate, except clypeus where the 

 punctures are coarse and sparse, becoming finer and closer at base, and 

 the sparsely punctured supraclypeal area; lateral angles of pronotum 

 strongly projecting, the projection forming a right angle; mesoscutum 

 with the anterior margin medially reflexed and carinate; the area just back 

 of this rugose; rest of mesoscutum with large strong punctures, those on 

 disk well separated; punctures of scutellum finer; propodeum with a tri- 

 angular enclosure bounded by a carina, the enclosure irregularly rug<i ; 

 rest of surface of propodeum covered with pubescence (worn specimens show 

 the posterior face rugulose and surrounded by a carina Avhich is slightly
