1908] COOLIDGE — WESTERN LEPIDOPTERA — I 83 



"Near San Rafael, in Marin County, I annually take specimens of a curious 

 variety of M . Icanira, so constant in its characters as to suggest the idea of a new 

 species. In the lower side of the typical form, the secondaries are marked with black 

 blotches near the base, and a double submedian band inclosing a series of seven spots 

 of the pale ochraceous color of the ground. In the variety obsoleta these marks are 

 all obliterated, and nothing aj)pears but the black ner\ades and a slight black marginal 

 line. In all other respects the insect agrees with the typical form. It is somewhat 

 singular that in the locality in which these varieties are found I never met with the 

 true leanira, which is a very local insect, and that, although I know several localities 

 in which Icanira is found, it is only in the one mentioned above that I ever met with 

 the var. obsoleta."

Callophrijs affinis Edw. — This species, I think, should properly be placed as a 

 synonym of dumcforum Boisd. V\^ H. Edwards, in his original description of affinis, 

 (Proc. Phila. Acad. Sci. XIV, 224) writes, "Both viridis (= dumetorum) and affinis 

 are related to T. Riihi and to T. Dumetoruvi of Boisduval. The latter I have not seen, 

 but it is briefly described as being entirely like Rubi, and to be considered a local 

 variety of that species, a description which does not apply to either of the above 

 named species. Affinis a])proaches most nearly to Rubi in color below, but the 

 upper side is much brighter, and the white spots of under side are wanting. Viridis 

 has similar spots to Rubi, but the color of both sides, is different, as is that of the 

 antennae, edge of costa and fringe." Dr. Boisduvals description of dumetorum is 

 as follows: "Wings olive brown without spots; anal palette of the secondaries nearly 

 obsolete. Under side of primaries russety, a little greenish; that of the inferiors 

 greenish, with a transverse row of small white points." The distinction between the 

 two, it would thus appear, is that dumetorum has on the underside "a common sinuous 

 band of elongated, clear-white spots (Edwards's description of viridis), while the 

 wings of affinis below are immaculate. Dumetorum ranges throughout California 

 and I have seen examples from a number of localities. The spotting of the under- 

 side varies so that it is rarely that a specimen is found which will answer perfectly to 

 the description' of either form. Wright (Butterflies West Coast) says under affrinis 

 "There are but few examples that are fully and fairly marked with the dots across 

 either wing ; most specimens have one or more dots on one of the wings, but in that 

 case they are a sort of intergrade, belonging to neither form." Edwards and 

 Boisduval evidently described their species from extremes. Dumetorum and affinis 

 are always found in the same locality. Prof. A. J. Snyder writes (Ent. News XI,
