 side the clypeus, the anterior tibiae in front and the posterior ones nar-

 nate behind, the face fairly wide, closely and rather deeply punctate 

 above tlie antennae, with a ver\' evident plaga immediately behind the 

 antennae, supraclypeal plate a little wider than long, cheeks extremely 

 short, scape of antennae dilated but nearly twice as long as wide, hind 

 margin somewhat curved, anterior margin almost straight, arched beneath. 

 ]\Iesoscutum and scutellum rugulose, shallowly and not too closely punc- 

 tate, propodeum finely rugose and wrinkled anteriorly. Wings somewhat 

 infuscate. Abdomen brighter than the head and thorax but hardly shin- 

 ing, the wings of the Jth ventral segment narrow, short and slender, 

 process of the 8th ventral segment short and slightly curved, greatly 

 expanded above, the expansion fringed with long hairs ; the bifurcations 

 also expanded with the surfaces clothed and the edges fringed with 

 fairly long hairs.

DiMiDiATA — 2 S 6 and 1 5 specimens taken at Kahnkn, 

 Kan, are referred to this. These forms are certainly rightly 

 associated, but the 9 does not conform to the description in 

 Fauna Hawaiiensis, and it is believed the original association 

 was wrong. The Kahnkn specimen is described as follows : 



Female black with two yellow lateral spots, an interrupted thin yellow 

 line on prothorax posteriorly, yellow tubercles and the base of the front

 banded. Head wide and of moderate length, fairly thick, emarginate be-
