LYC^NID^. 187 



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, l)ut 

 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 



Ulirysophamis hypoiilaeas, var. 



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 with tlie 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- 

 ino- the wino-s, is dull reddish-brown dotted with black. The abdo- 

 men is much lighter with very distinct and irregular black dots. 

 The clnysalis 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 tln-ough 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 Chri/sopJuams 

 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
