LYCLENIDiE.

this species collected in Wellesley, Massachusetts, during May of 1897, 
I took no very striking varieties of any kind, but in the same year 
during August I collected five hundred more, with the result of ob¬ 
taining half-a-dozen well-marked specimens of the dark variety, but 
not one of the light. Whether this is a sufficient number to give 
an idea of the percentage of such variations I cannot say, but one 
would infer from this that the second brood is much more liable to 
variation than the first, and that the light variety with almost no 
spots is of much rarer occurrence than the dark variety. In some of 
the dark variety the black almost covers the entire wing, making the 
insect look like a totally different species. The caterpillar of this 
butterfly is longer and narrower than is usual witli the larva of 
butterflies of this family, is covered with hairs, is reddish, pinkish or 
greenish in color and feeds on the common sorrel. The chrysalis is 
short and stumpy, like that of most of the species of the family. 
Mr. Packard says of the chrysalis : “ The head and thorax, includ¬ 
ing the wings, is dull reddish-brown dotted with black. The abdo¬ 
men is much lighter with very distinct and irregular black dots. 
The chrysalis is usually suspended under a stone.” There are two 
or more broods in a season. The geographical range of the species 
is wide, being found along the Atlantic coast southward, throughout 
the middle states and through Canada, west into Washington and 
in California. A very closely allied if not the same species occurs 
throughout Europe. 
Our largest and handsomest species of this genus is Chrysophanus 
thoe , and an exceedingly fine butterfly it is, an ornament to any cab¬ 
inet. The insect expands from an inch and a half to two inches 
or more, the female being usually somewhat larger than the male. 
The upper wings of the male are a beautiful bronze-brown, having
