which I have so far been able to discern Hes in the subterminal 

 line. This is brighter and more irregular in thoracica, and is thrown 

 more into contrast in fresh specimens by the dark preceding and 

 following shades. But in worn and hibernated specimens con- 

 trasts become lost. The black dash before the s. t. line opposite 

 the reniform is slightly heavier and longer in thoracica. The 

 reddish costal shades are often of a lovely bright chestnut in fresh 

 specimens. They are far duller in cineritia. The thorax is always 

 a trifle grey. But none of these characters are at all obvious, 

 and a student will require to become familiar with the sight of 

 both before being able to distinguish them with certainty. Both 

 occur in Manitoba, but I have not so far received thoracica from 

 B. C. where cineritia, apparently redescribed by Smith as mertena, 

 seems widely distributed. I have thoracica also from Glenwood 

 Springs, Colo. I have what I believe to be a very dark, small, 

 subarctic form of this species from Dawson City, Y. T., and have 

 seen an exactly similar form taken by Mr. Sanson at Banff. 



Mr. Tams has prepared seven mounts of the genitalia of each 

 species, but we are entirely unable to find any difference between 

 the two as Dr. Ottolengui appears to have done. The harpes are 

 bifurcate, and their form at the tip may be likened to a snake's 

 head with open jaws. The relative length and shape of these jaws 

 varies considerably in the fourteen specimens, but the organs of 

 the two species vary to the same extent. 



C:)':>o. Rancora solidaginis Behr. — Banff, May 4th, 1911 

 (Sanson ). A specimen bearing this date was sent to me for naming, 

 and I compared it with the British Museum material, amongst 

 which it agTeed with a specimen from Osoyoos, B. C. Holland's 

 figure under solidaginis appears to be albicinerea, a closely allied 

 but paler form already recorded by me from Alberta. In the 

 Entomological Record for 1912, Mr. Sanson records this species 

 from Banff under date Aug. 20th. The date, if correct, is probably 

 abnormal. 



G5(5. Asteroscopus borealis Smith. — A male, in perfect 

 condition, taken at rest at Red Deer, about April 24th, 1914, by 

 Mr. F. C. Whitehouse, to whom I am indebted for the specimen.
