A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 



43 



bisinuate at apex, without a submarginal ridge, lateral margins coarsely serrate; 

 eighth tergite broadly rounded at apex, densely granulose, coarsely, sparsely 

 punctate. Prosternum densely, coarsely punctate, sparsely clothed with long, 

 erect, white hairs, with a distinct, broad, short lobe in front. Anterior femur 

 with a long, acute tooth, which is coarsely dentate on outer margin. Anterior 

 tibia strongly arcuate, unarmed; middle and posterior tibiae straight. 

 Length 9.5 mm., width 4 mm. 



Type locality. — Willows, Calif. 



Redescribed from the single female in the collection of W. J. 

 Chamberlin, collected July 2, 1935, by H. A. Scullen. 



Male. — Unknown. 



This species is known only from the female holotype. It resembles 

 chamberlini very closely, and since that species was known until 

 recently by the male holotype only, the writer was inclined to place 

 bisinuata as the female of chamberlini. Recently Mr. Beer collected 

 three males and one female which he identified as chamberlini and he 

 describes the female as having the last visible sternite rather com- 

 pletely rounded at the apex. Since the apex of the last visible sternite 

 in the females of these two forms is quite different, it seems advisable 

 to recognize bisinuata and chamberlini as valid species, at least until 

 the males of both species are known and more material is available 

 for study.
