were sent to Clifton Springs, New York, to go in the refrigerating house, 

 and there they are at this writing. 



I had previously had eggs of the species from Mr. David Bruce, 25th 

 July, 1886, laid on 21st and 22nd July, and which hatched 26th. On 

 31st July several of the larvae passed first moult; on 6th August began 

 to pass second ; on 15th, the third. None of these went to pupas, but 

 all were asleep early in September, and were sent to New York, but 

 were dead when I received them the following March. 



The egg and pupa are like the same stages of Philodice in shape ; 

 the larva is darker than any Colias I know of, and there is no red in the 

 basal stripe. The sub-dorsal line is not very distinct, but its place is 

 indicated by the row of black spots next it on lower side. 



I had no difficulty in rearing these larvae on white clover, but at same 

 time, in 18S8, could not induce larvge of C. Sciidderii to eat clover or 

 any other plant, and all died. The same was the case with C. interior. 

 Mr. Fletcher and Mr. Scudder both also found it impossible to get larvae 

 of interior to eat of any plant, though they offered everything any Colias 

 is known to eat that was procurable. These two larvae are the only 

 Cohas known to me that will not freely eat white clover or else Amorpha. 



COLIAS C^SONIA, Stoll.

Somewhat to my surprise I found this species not uncommon here 

 during the collecting season of 1887. Although my entomological interest 

 lies in another direction, and I have, consequently, made no special effort 

 to obtain Lepidoptera, I find I have ten specimens of this striking Colias 

 in my collection, all of which I have taken during the summer and fall of 

 1887. On looking over the collection I discover that these specimens were 

 taken at three different times. One — a very much worn specimen, with 

 one hind wing gone— was captured the sixth of June, on Rock Island ; six 

 specimens were taken on the tvt'enty-third of July in an upland clover 

 field, two miles south-west of Moline. They are all fresh and bright, and 

 were found in company with C. philodice, Papilio chresphontes, P. tiirnus 

 and Danais archippus. The last three were taken September the six- 

 teenth, in a low-lying field, on the banks of the Mississippi, three miles
