36 THE CANADIAN ENTOMOLOGIST. 



been described from the mountains of Colorado as a purpurissata, and 

 subsequently, in Ent. News, IX, 241, Dec, 1898, separated as a species. 

 My only Colorado specimen is a female from Durango, and looks like an 

 obscure piirpurissata merely. Vancouver Island specimens are paler and 

 more distinctly maculate than any others that I have. I believe that 

 crydma is merely a strongly marked form o\ piirpurissata^ and junc'unacula 

 is very doubtfully distinct. 



287. M. Columbia Smith. — I have seen two specimens of this form 

 marked " type," both males labelled " Ft. Calgary, B. C," one in the Neu- 

 mcejen collection, and the other at Washington. The description refers 

 to both male and female types, which may be an error. In 1884, when 

 Capt. Geddes collected the specimens, Calgary was merely a Northwest 

 Mounted Police fort. The " B. C." error I have repeatedly corrected. 

 Closer acquaintance has brought me to look upon this as a local race of 

 meditata Grt. The majority of Calgary specimens are considerably paler 

 than meditata from the Eastern States, and tinged with reddish rather 

 than brown. Specimens from Cartvvright, Man., and Redvers, Sask., 

 include obvious intergrades, as well as specimens inseparable from some 

 in both eastern and Calgary series, except in being smaller, as is usual 

 with Manitoba and Saskatchewan races. Déterminât a Smith is a Colorado 

 form very closely allied to these, with darker central band, and rather 

 conspicuous discoidal spots, those in meditata and Columbia being usually 

 rather obscure, and sometimes scarcely discernible. Sir George Hamp- 

 son separates determinata from the other two in the tables on the charac- 

 ter of the orbicular being concave anteriorly. This is a variable character 

 in my Columbia series, in which I do not suspect two species. I have 

 only a single Colorado male in my collection, from Colorado Springs, and 

 a few of my local specimens come very near it. Prof Smich has a good 

 series from California, 



288. M. cervina Smitli. — I do not feel at all confident that this is 

 distinct from Instralis, of which the tyi)e is a Wisconsin female in the 

 British Museum. The eastern form does not appear to be very common, 

 and I have not the material to enable me to form a definite opinion. The 

 character by which Hampson separates lustralis from cervina in the table 

 is the presence in the former of a black mirk preceding the white patch 

 near the anal angle in submedian fold. In his description, however, the 

 mark is called brown. A brown mark is faintly discernible here in some 

 cf my local series oï cervina. It is rather more evident in my one lustralis
