m-cu crossvein being present. As far as its distribution and color 

 characters are concerned, however, it could represent an atypical 

 specimen of several species, such as borealis, adaptatus, or eugonatus. 

 Nevertheless, Cole's figure of niger plainly shows crossvein m-cu 

 present, a character not found in other species of either the eugonatus 

 or pallidipennis groups. The presence of crossvein m-cu together 

 with the fact that females are unknown for most species of the colei 

 group suggest that niger probably belongs in this latter group. 

 That females of the strikingly patterned males of the colei group 

 should be of the simple fasciated type has now been partially verified 

 by an examination of females of both colei and vittisternum, as well as 

 (Neogcodes) alhiventris. 



A possibility that the wing venation of niger females may be different 

 from niger males was discussed under colei (see above).
