patches of Dentaria in the neighborhood along the ridge and 

 found six eggs of genutia. Came across a male and female 

 genutia on a flowering raceme of Dentaria. They were rest- 

 ing on the flowers and below the cluster, close to each other, 

 wings closed, fore wings drawn far within and overlapped by 

 hind wings, and antennae touching the fore costae. I took 

 them with the cyanide jar. 



April 2oth. Caught two ma\& genutia. 



April 2 2nd. Warm and bright ; saw twenty-one and caught 

 nineteen genutia, two females and seventeen males. I pursued 

 one female, which flew up hill and took to the open fields ; 

 when close to her, she disappeared behind a tuft of small 

 shrubs, nor could I start her again, though I stirred and beat 

 the bushes thoroughly. 



I took one male at rest and feeding upon Dentaria flowers, 

 the wings were held open, nearly at right angles. 



April 26th. Found eleven eggs. 



April 27th. Caught two males and two female genutia; 

 one of the latter when pursued flew up hill into the open, and 

 was caught after a smart race. The males generally fly down 

 hill when pursued, and I find a cautious approach while they 

 are idly hovering is better than a headlong rush. They must 

 be taken on the wing, however, as they seldom light. 



April 28th. Took two female genutia and found four eggs. 



April 29th. Caught five males and two female genutia. 



May ist. Found about sixty eggs of genutia and Dentaria ; 

 in some cases, three eggs on one plant ; on a number of plants 

 I found two eggs, though one egg to a plant was the rule. In 

 one case the egg was on a sepal, in another, on the underside 

 of a withered petal which dropped as the plant was touched ; 

 in a few cases the eggs was on the flower pedicel, but usually 

 on the rachis at the base of the pedicel. 



May 2nd. Took two male genutia. These were the last 

 seen of the first brood ; there was then a gap, as fas & genutia 

 was concerned, until - 



May 26th. Saw \.vfO genutia, and caught one, a fresh female. 



May 27th. Saw one genutia, in open woods on the oppo- 

 site side of the College and about three miles from the ridge to
