east, if at all. The wings have a rougher appearance. Oliva- 

 ceous and red shades predominate to the exclusion of pur- 

 ple, and the secondaries in all my specimens are almost uni- 

 formly dark fuscous, darker than in eastern specimens, and 

 lack the bronzy sheen and pink fringes so often found there. 



I recently sent Sir George Hampson a Calgary specimen 

 as pectinatus. He commented that it was "tertialis, not pec- 

 tinatiis." In so far as the color is concerned he is perfectly 

 correct, and I quite admit that the Calgary form is tertialis, 

 which appears to me to intergrade with emmedouia. As to 

 whether pectinatus is really a biologically distinct entity, not 

 habitually interbreeding, somewhere or other, with the same 

 form, that is to say. whether a distinct racial connection will 

 not ultimately be found to exist between the extremes refer- 

 red to in this article as North American specimens, is a mat- 

 ter of some doubt. What I have been able to observe from 

 the data at my disposal suggests to me that they are not dis- 

 tinct. For the present, not being able to trace an actual con- 

 nection through, and possessing no specimens from anywhere 

 between Calgary and Victoria. I feel bound to leave the name 

 pectinatus as it stands. I should mention that I have females 

 from most of the above mentioned localities, and that they 

 do not differ essentially from the males except in having mi- 

 nutely ciliate antennse. 



Of all the seventy-four specimens examined. I have dis- 

 covered a single but unmistakable spine on a single hind tibia 

 of two. one male and one female, from Husavick, Man. It 

 is situate in both on the outside of the limb, in distance about 

 midway between the two pairs of spurs. Though at present 

 I have investigated very little in the matter. I know of a num- 

 ber of species in which the presence or absence of tibial spines 

 is variable, but this is the first instance in which I have dis- 

 covered any on tibiae of a hairy-eyed species. The only other 

 hairy-eyed species in North America that is known to have 

 spined tibiae is Trichorthosia parallcla.
