SCOTOGRAMMA DENSA Smith 



No specimens. I refer with hesitation to this species, a single 

 female from Mr. Cockle's collection, taken July 81. It is of a dark 

 gray, produced b}^ white powdering on a bluish black ground and 

 patches of ocherous yellowish, most distinct in a line at base of fringe. 

 It has a very different look to the types of dcnsa and is doubtless 

 worthy of a new name; but from the single specimen I do not care to 

 characterize it. 



SCOTOGRAMMA UNIFORMIS Smith. 



Two specimens, July 29 (Bear Lake Mountain) and one in Mr. 

 Cockle's collection, August 8, 1902 (McGuigan). ^\v. Cockle's speci- 

 men is a female, more distinctly marked than the males, and 

 approaches infuscata Smith, which is probal)ly not specitically dis- 

 tinct from this. 



SCOTOGRAMMA SEDILIS Smith. 



Five specimens, June 2(;, July 21, 2l»(I^*"^i" Lid^e Mountain), August 

 13 (Sandon, Mr. Currie). A female agrees well with the type of i<edills 

 Smith; the rest, a male and three females are not different from what 

 I have SiSj^erplexa Smith. I have not the type of the latter, so do not 

 make this synonymy at present. A speciuKMi in Mr. Cockle's collec-
