THE CANADIAN ENTOMOLOGIST 63 



suggests a resemblance to perexcellens, though admitting a marked 

 difference in antenna^. The association has occasionally been made 

 by others, with certain forms of it, but seems to me rather far- 

 fetched. 



My own notes on Smith's types say that the d^ is "almost 

 like some ochrogaster/' and that the 9 ,. which I was able to match 

 pretty closely, is much greyer, a fact mentioned by Smith. A few- 

 weeks later I compared my same specimen with type thanatologia, 

 and more than suspected their identity. This has since been con- 

 firmed by examination of additional material, including a co-type 

 of boretha, in Mr. Cockle's collection. 



Var. sordida Smith. Also described as a species, picked out 

 of the same lot sent him' by Cockle. An extract of the description 

 is: " Dull sordid brown, more or less shaded with black and smoky 

 Collar concolorous, with a black median line. . . ' . A diffuse 

 black streak through basal space. Cell darker or even blackish, 

 but not solid black filled. Subterminal line marked by a slight 

 darkening of terminal space, and by a preceding series of black 

 interspaceal marks. Claviform narrow, pointed. Orbicular small, 

 round or ovate, ringed with yellowish. Reniform large, edged 

 with black; with an inner ring of yellow scales, and the centre 

 more "br less yellowish and discoloured." Described from 1 cf 

 and 5 9 9. He adds that the maculation is like that of some of 

 the species of the ochrogaster series. With this remark I entirely 

 agree. He states further: "It differs from boretha in the flattened 

 appearance, and in the concolorous orbicular, costa and collar. It 

 varies in the amount of overlay in the median space, one example 

 being almost purplish black." The flattened appearance is charac- 

 teristic of the female, which sex predominated amongst his speci- 

 mens called sordida. A comparison of the types with boretha 

 certainly showed some contrast in the discoidal spots, but I do not 

 think I should ever have ventured a separation upon these char- 

 acters in anything allied to an Euxoa. My notes say of types: 

 "The male is near some forms of agrestis." I matched the 9 type 

 prettly closely with a Calgary cf , which up to that time I had 

 held as a unique, though since then I have been able to find links 

 connecting it with the rest of my material. Mr. Cockle has
