$ . Length about 7 mm. ; black, with the tegulae dark brown, and 

 the tarsi obscurely more or less brownish ; wings with the apical margin 

 broadly dusky; nervures piceous, stigma dull reddish. Vertex dullish, 

 with large irregularly-placed punctures ; cheeks with much white hair, 

 and below with a broad shining beveled space ; eyes black, their pubes- 

 cence only moderately long; face covered with white hair; antennae 

 entirely black ; mandibles black ; tongue and labial palpi bright ferrugin- 

 ous ; mesothorax and scutellum shining, with large close punctures ; 

 scutellum with no median projection, its lateral teeth small and curved; 

 anterior border of mesothorax with a practically continuous band of 

 creamy-white scale-like hairs ; posterior lateral corner of mesothorax 

 with patches of white hair, and some in scutello-mesothoracic suture ; 

 spurs ferruginous ; abdomen shining, with strong but well-separated 

 punctures ; hind margins of segments I to 5 with conspicuous narrow 

 white hair bands ; first segment with a weaker band round the edge 

 of the basin ; no other bands, but third and fourth segments with a little 

 hair in the transverse depressions ; fifth segment strongly toothed at sides

 six as usual but the upper apical ones are rudimentary. Among Ameri-
