This species was associated with Dasyneura rhodo- 

 phaga Coq., though from the habits of allied species it was 

 evidently preying upon rose aphids. A study of type material 

 enabled us to establish the correct generic position of the species. 



Male. Length 1.5 mm. Antennae twice the length of the body, 

 thickly haired, brown; 14 segments, the fifth with stems three and 

 three and one-half times their diameter; terminal segment with the 

 basal portion of the stem and the distal enlargement greatly produced, 

 the latter with a length five times its diameter, broadly constricted 

 near the basal third and apically with a long, fingerlike process. 

 Palpi yellowish, first segment quadrate, the second with a length 

 thrice its diameter, the third one-half longer than the second, slender, 

 the fourth a little longer than the third. Mesonotum light brown, 

 the submedian lines yellowish. Scutellum and postscutellum yellow- 

 ish, the abdomen yellowish orange. Halteres whitish transparent, 

 slightly reddish apically; claws long, slender, strongly curved. 



Female. Length 2 mm. Antennae nearly as long as the body, 

 sparsely haired, brown; 14 segments, the fifth with a stem one-fourth 

 the length of the cylindric basal enlargement, which latter has a 

 length three and one-half times its diameter; terminal segment, 

 basal enlargement with a length fully five times its diameter and a 

 stout appendage. Mesonotum light brown, submedian lines yellow- 

 ish. Scutellum and postscutellum yellowish. Abdomen yellowish
