(*) Dr. Smith say.s, under heading "Rhi/nchar/roth placida, 

 Grt.": "Thi.s .sjiecific name has served as a blanket for all narrow- 

 winged forms. . . . There are really two forms concerned, the 

 ty))e placida with an obvious median shade line in both sexes, and 

 the other without this character." He was wrong in considering 

 that "placida" always has the median shade. There is usually at 

 least a trace of it in about 80 per cent of the specimens of "placida," 

 but that is as far as it goes. As stated vmder the heading Group 

 Placida, there is no single character or set of characters, genetalic 

 or otherwise, that will serve to separate "placida" from the rest of 

 tlie genus. 



The name negascia in our lists must change to nefascia. Smith 

 intended it to be nefascia. His "f" is made j^eculiarly similar to a 

 "g." but is plainly an "f" on three "cotypes" in the Barnes Collec- 

 tion. The spelling negascia instead of nefascia is clearly a typo- 

 graphical error, as on page 471 of Can. Ent., XL, under the heading 

 "Corrigenda," is "Page 227, line 4 from bottom, for negascia read 

 nefascia. Fortunately on page 222 of Smith's paper, five images 

 before this error is at least enough of a description of nefascia to 

 hold the name in case of dispute. Quote: "There comes a series of 

 species with somewhat elongate, subparallel wings, with rounded or 

 stumpy outer margins. They are all variable, and it is difficult to 

 divide them on exclusive characters. I include nefascia, duanca, 

 cupidissima." 



Dr. Smith's original description of nefascia is clear and concise 

 and exactly corresponds to the series before the author. A point 

 that might be added is that the antennae are finely ciliated with 

 longer setae from the segments. The genetalia show but little vari- 

 ation. Their most conspicuous feature being a very slim curved 

 "arm" projecting from a huge saculus (the valve) ; best visualized 

 by a glance at the figure.
