369. Pyrrhia exprimens Walk. — I have compared this form with 

 Walker's type from Orillia, Ontario, and consider it correctly 

 named. Angulata Grote, from Buffalo, N.Y., is the same species. 

 It is the one with almost blackish central shade and t.p. line, and 

 blackish bordered secondaries. It stands wrongly in Dyar's 

 Catalogue as a variety of umbra Hufn., a European species which 

 should be struck out from our lists altogether, and place given to 

 cilisca Guen. I have not, as a matter of fact, seen the type of 

 cilisca, but Sir George Hampson has, and gives the locality as 

 "Brazil" in the Catalogue. It is in Mons. Oberthiir's collection at 

 Rennes. In the British Museum is a Kansas specimen from the 

 Snow collection, marked "cilisca Guen," which I must assume 

 has been compared with this type. This is the species figured 

 by Holland as umbra Hufn., and is the umbra in error of all North 

 American authors. 



In cilisca the primaries have a crimson irroration which seems 

 to be lacking in exprimens. The cross lines are finer and not 

 blackish, and the central shade is less acutely angled in the cell. 

 The secondaries are crimson-bordered, and not blackish. All my 

 specimens of cilisca are from the Eastern States, and I have both 

 this and exprimens from Milwaukee Co., Wisconsin. Both seem 

 to occur all across the continent in the south, but I have not yet 

 seen cilisca from Western Canada. 



The European umbra combines some of the characters of the 

 two, but I carefully examined the British Museum material, and 

 all the British literature and figures in my possession, and it seems 

 to me to be easily separable from both. It has the dark-bordered 

 secondaries more like exprimens than cilisca, but the transverse 

 lines are like those of the latter, though it usually lacks the pink 

 irroration. I happen to have but a single example of umbra in
