AEDES IMPIGER 755 



St. Martin's Falls, Albany River, British America (Kirby). 



Unknown to us. Giles states that the types are two males in fair preserva- 

 tion. He describes the mesonotum as " dark red brown, with five lines of 

 brilliant white tomentnm, viz., a fine median ; two complete broad lateral, and 

 external to these again a narrow pair of lateral lines incomplete in the middle." 

 Theobald states that the types are two males and one female and describes the 

 ornamentation of the mesonotum as follows : 



Thorax deep brown, covered at the sides with narrow creamy curved scales, which 

 form a line on each side passing back to the scutellum; between these two lines the 

 mesonotum is covered with deep briglit chestnut-brown, narrow curved scales, there 

 being a narrow median double line of pale scales in the middle separated by a distinct 

 darlf bare line; the pale scales of the median lines spread out round the bare patch 

 in front of the scutellum and form a pale patch ; there are three rows of dark bristles 

 which become paler posteriorly; the sides of the mesonotum are deep black, with 

 scanty creamy scales. 



We do not feel safe to identify this species in any of the material before us. 

 The name was applied by Coquillett to a mixture of species, hence its applica- 

 tion by American authors to several species. We can not consider the introduc- 

 tion of the name punctor in this manner as a restriction and it will be found in 

 the proper places in the synonymy.
