400 THE CANADIAN ENTOMOLOGIST 



594. A. felina Grt.? — I have a single male taken at the head 

 of Pine Creek on June 20th, 1895, being one of those four specimens 

 originally treated by me under canadensis, which I have compared 

 with a male type of felina from the Sierra Nevada in the British 

 Museum. This type is well figured on Plate CXXVI, fig. 3, of 

 Hampson's Catalogue, but the figure is too brown. My specimen 

 differs in a few minor details, but appears to be the same species. 

 There is a female type of felina from the same locality in the Henry 

 Edwards collection, which did not satisfy me as being the same 

 species as that in the British Museum, but this comparison was 

 from memory only. It seemed to me nearer cyanescens Hampson, 

 from Vancouver, but paler. At any rate the two are close allies, 

 and metra Smith, from Seattle, Wash., and Colorado, is doubtfully 

 distinct from cyanescens. The felina of the British Museum is not 

 like that figured in Smith and Dyar's Monograph. 



595. Arsilonche henrici Grt. — Two specimens, June 17th, 1906, 

 and June 5th, 1910. They are much darker and more streaky 

 than my specimens from the east and are irrorate with smoky. 

 The species appears to have a wide range of variation. The type 

 of henrici is very streaky and grey, that of evanidum being rather 

 even and not grey. Both are in the British Museum and appear 

 to be from New York. Fumosum Morr., of which the type is in 

 the Tepper collection, is called "ab. 1 " by Hampson, almost 

 entirely suffused with slate-grey." Sir George Hampson keeps 

 henrici distinct from the European albovenosa as being darker 

 brown and having blunter apices to the primaries. My own notes 

 say, concerning the British Museum series: "All are much more 

 even and less powdery than a series of albovenosa here." Some 

 European students, including Tutt, have claimed to have found 

 them identical. As regards my series from each continent, the 

 differences in wing form certainly do not hold, and the contrast 

 between the pale veins and the ochreous or brown interspaces is 

 greatest, as a rule, in North American specimens. My Calgary 

 examples, which seem to be about typical henrici, agree very closely 

 in colour with a Bavarian specimen sent me by Bang Haas as ab. 

 albida Auriv., but have more dark intcrspaceal shades. I neither 

 possess, nor have I seen, any specimens which cause me to consider 

 albovenosa and henrici strictly synonymous, though the relationship
