COLIAS IV. 
Mr. Bean also bred from Keewaydin 9, which laid five eggs 1st August, 1876. 
From these lie obtained two butterflies, 15th and 19th September, one of them 
Eurytheme <?, the other Keewaydin $. 
And he gives the following statement of his captures at Galena. 
I. Eury theme S, typical form. 
30th May, faded, evidently a hybernator; 29th June (1st brood); 6th, 10th 
August (2d brood); 21st September (3d brood). 
Eurytheme 9 ; 11th July (1st brood); 27tli August (2d brood); 24tli Septem¬ 
ber (3d brood). 
II. Intermediate examples. 
4th, 18th July (1st brood); 6th August (2d brood); 15th, 24th September 
(3d brood); 8th, 10th October (belated 3d brood). 
III. Keewaydin $, typical form. 
22d June to 4th July (1st brood); 20th September (3d brood). 
Keewaydin 9 ; 18th July to 3d August (2d brood). 
The typical Ariadne Mr. Bean has not seen in Illinois. 
Mr. Worthington states that he took Eurytheme, in 1876, 30th May (hyber¬ 
nator) ; 1st July (1st brood) ; in 1877, 29th May (hybernator); 4th July (1st 
brood), and at intervals thereafter till frost. And Keewaydin 10th June, 1877, 
and at intervals -thereafter till 10th September. But the form Ariadne he has 
never seen in Illinois, nor does he find it in several local collections examined. 
The nearest approach to it is the intergrade, designated above as Var. A. 
Mr. Dodge, who lived several years in Illinois, and for several more has lived 
in Nebraska, giving his experience in both States, says: “As regards Ariadne ” 
(which I had sent him), “ I have never seen it before. I have never taken it. 
I have taken the other two forms both here and in Illinois, and am sure no such 
form as Ariadne exists at the North. I have seen the species flying here 
as early as the second week in May, some seasons not till last of May. There 
were in Illinois three distinct broods. In May, I used to find a few hybernated 
specimens, usually too much worn for identification. In June the first brood 
appeared. I had to look for these on the uncultivated prairie. This brood was 
never large in number. The second brood appeared in midsummer, and in Sep¬ 
tember the third. The butterflies then became quite plenty on clover.” Speak¬ 
ing of Nebraska, “ I think the species hybernates both as imago and larva. I 
usually find fresh specimens in May that must have just emerged from chrysalis, 
but the worn and battered ones are the most abundant. The first brood ap¬ 
pears about the middle of June, the next, middle of July, and the third in Sep¬ 
tember. If the weather is warm, the butterflies are abundant in October.” 
The earliest butterflies spoken of by Mr. Dodge as fresh from chrysalis were evi-
