THE VELUTIXOUS SPECIES OF THE GENUS 

 CHRYSOPILUS. 



By Charles W. Johxson. 



Among the species of the genus Chrysopilus is a small group 

 of velvety looking flies with dark smoky wings. These show an 

 interesting combination of colors: — velvety black, with or without 

 golden tomentum on the thorax and silvery white tufts of hairs 

 on the abdomen, and comprise some of our most beautiful species 

 of diptera of eastern and central North America. The group 

 consists of four species, which can be readily defined by the fol- 

 lowing table: — 



1. Thorax entirely velvety black 2 



Thorax covered with a dense golden tomentum 3 



2. Abdomen entirely velvety black velutinus Loew. 



Abdomen with two rows of tufts of white pile connexus sp. nov. 



3. Abdomen entirely velvety black davisi Johns. 



Abdomen with two rows of transverse tufts of white or light yellow pile 



thoracicus Fabr. 

 Chrysopilus connexus sp. nov. 



Male and Female. Front and face velvety black, antennae, proboscis and palpi 

 black, the latter and the inferior orbits with long black hairs. Thorax with velvety 

 black tomentum, scutellum with long black hairs and a tuft of yellowish hairs 

 in front of the halteres in the male, pleurae browTiish back. Abdomen velvety 

 black with two rows of tufts of white hairs on the posterior margins of the first 

 to fifth segments, very small on the fifth segment of the male and apparently wanting 

 in the female, the other tufts are more conspicuous in the female than in the male, 

 venter velvety black, coxae and femora black, tibiae and tarsi yellow. Halteres 

 browTi. Wings smoky with the veins broadly margined with brown. Length 

 male, 11 mm., female, 12 mm.
