The material in the National Museum referred to slossonae is as 

 follows : Four types of slossonae^ both sexes, from Franconia, N. H. 

 (Mrs. Slosson), Eastport, Me. (coll. C. V. Riley), and Westville, N. 

 J. (Johnson) ; the female type of spinipennis Coquillett, from Tif- 

 ton, Ga. (Pilate) ; a female from Franconia, N. H. (Townsend) ; 

 a male from Chevy Chase Lake, Md. (Townsend) ; a female from 

 Potomac Run, Va. (McAtee) ; two males from College Park, Md. 

 (Walton) ; a male from La Fayette, Ind. (Aldrich) ; and a male 

 from Birmingham, Ala., reared by H. L. Weatherbee from EpiJachna 

 corrupta Mulsant, the Mexican bean beetle. The last emerged on 

 August 3, 1922, and this is the only rearing record. 



EXORISTOIDES SETIFERA Townsend 



Exoristopsis setifera Townsend, Proc. U. S. Nat. Mus., vol. 49, p. 426, 1915. 



The only specimen in the National Museum is the type, a female 

 from Peru. 



The characters given for the genus Exoristopsis by Townsend seem 

 mostlj^ specific, especially when considered in relation to the other 

 species than johnsoni, which I here include. Perhaps the most impor- 

 tant is the small size of the ocellars, which is shared by urichi, new 

 species. No mention is made of the pteropleurals, which are broken 

 off, but the scars are distinct. 



EXORISTOIDES URICHI. new species 



Black with silvery-gray pollen. Fourth abdominal segment red 

 or reddish in ground color with yellow pollen. 



Male. — Front 0.27 of head width, pollen of the head silvery gray, 

 the posterior orbit and upper part of front slightly yellow. Ocellars 

 hairlike, proclinate, two upper frontals reclinate, six others, the 

 lowest at the level of the base of third antennal joint. Antennae
