104 THE CANADIAN ENTOMOLOGIST. 



50. Colias philodice. — Very common and producing about four broods 

 in a season, its appearance some seasons being nearly continuous from 

 the first of May to the end of October, and in 1890 seen November 20th. 

 Occasionally in spring a form resembling ant hy ale is seen, expanding 

 but 1.5 inches. Var. alba is more abundant in the late summer broods. 

 A third variety occurs which I have nowhere found described, but which 

 is distinct from any variety given in Smith's List, and seems to me to 

 merit a varietal name. 



Colias philodice, var. luteitincta, nov. var. — Differs from the normal 

 philodice in the possession of an orange shade upon the primaries ex- 

 tending from the middle of the posterior margin to the median vein, shad- 

 ing off in all directions into the yellow ground colour, and occupying 

 exactly the position of the orange patch in Col. eurytheme, var. ariadne. 

 The secondaries also in most specimens show an orange flush in the central 

 portion. I first met this form in company with eurytheme and philodice in 

 August, 1885, at Batavia, Ills., and supposed the specimens to be 

 hybrids. But have since taken it at different times at Grand Rapids, where 

 eurytheme has been seen but once, and have collected in all about a 

 dozen specimens, one of them a female. I find the colouring very 

 constant and sufficiently marked to distinguish the form even when on the 

 wing. Have recently seen a specimen in a collection at Lansing, Mich. 

 Edwards figures an orange variety and suggests the possibility of its being 

 a hybrid between the two species, eurytheme and philodice ; it is not like 

 this and appears much more likely to be, as suggested, a hybrid. 



51. Terras lisa. — Rare. One specimen taken east of the Michigan 

 Soldiers' Home, August 10, 1891. 



52. Papilio ajax. — Formerly rare, but has been becoming constantly 

 more common with the spread of the papaw, upon which it feeds, till 

 now it is very common in the southern part of the country and quite so 

 at Grand Rapids, especially in the vicinity of its food-plant. Vars. 

 telamouides and walshii fly from the early part of May to the latter part 

 of June, and marcellus from the end of July to the end of September. 



53. Papilio turuus. — Common from the end of May to the early 

 part of July, congregating about wet places in roads, etc. Var. glaucus 

 is rare. Two specimens have been taken on the wing and one reared 

 from a larva collected on cultivated cherry. 



54. Papilio cresphontes. — Not uncommon in June.
