* I refer this genus here, following Mr. Smith, but with hesitation. I had regarded 

 the moth as allied in shape of wing to Sisyrhypena. It resembles in ornamentation a 

 very dark Parac.olax grisealis, in which the lines are lost aud only the paler curved termi- 

 nal marking contrasts. I do not consider the absence of secondary sexual characters as 

 excluding the moth from the Herminiini. Mr. Smith states that I gave him a specimen 

 of S. salicalis labeled "Texas." I do not recollect having doue so. Until I read the 

 statement I was not aware that the European form occurred in North America. In any 

 event I am uuwilling that the species should be recorded from Texas on my authority. 

 Mr. Smith's statement is incredible tome aud surprises me ; I kept no list of what I gave 

 him, but I must disclaim any knowledge of the occurrence of S. salicalis in North 

 America, having always believed the species to be represented by S. interpuncta, as hither- 

 to assumed in all my papers on the subject. The Arizona material, coll. Neumcegen, has 

 the subterminal space shaded with reddish brown ; if it does not represent a species, it 

 certainly does a good variety. No similar variatiou is noted of S. salicalis. Mr. Smith's 

 figure, PL viii, 4, is misleading, not showing the discal dots ot interpuncta.
