EGG-LAYING OF TKRIAS LISA. 



The female Tcrias lisa deposits its eggs in a very systematic 

 and unilorm manner. It moves about in a fluttering way so 

 characteristic of butterflies when ovipositing, and lights on the 

 tip of the leaf Cassia nictitans, facing toward the stalk of tin- 

 plant and walks up the K-at until the end of the abdomen is mid- 

 way between the end of the leaf and its junction with the main 

 stem and then deposits the egg on the uppers 1< of tin- st'-m or 

 mid-rib that runs between the leaflets. It moves with i^ivat care 

 and precision, as though such nicety were very necessary. The 

 egg is thus placed at what might be called the exact centre of the 

 leaf. There seems undoubtedly to be design in this, as the eggs 

 are exceedingly frail and delicate, and if deposited on the leaflets 

 they would probably be injured or crushed when they close up 

 tight at night. I did not notice whether the eggs were placed 

 between the junctures of two sets of leaflets on either side, but I 

 think such was the case. When the females are confined over 

 the plant the eggs are scattered about indiscriminately either on 

 the Cassia, or anything else near it. They were found oviposit- 

 ing here in the last week of August, and at Westville, X. J., in 

 September. 



THE FIRST STAGES OF PA Ml' HI I. A PANOQUIN. 

 August 22d, Pamphila panoquin was exceedingly abundant on 

 the meadows flying about and feeding on the flowers of Staticc. 

 They were fine, bright specimens. This .species does not semi to 

 have as much of the jerky flight as most species <>\ th< - nus, 

 but flies generally in a straight line. It is readily caught when 

 feeding on the blue flowers, which attract it greatly, but when in 

 the net is exasperatingly restless, and usually manages to denude 

 its thorax of hair. A female deposited a te\\ t ggs in the paper in 

 which it was confined, not having been pinched hard enough t,, 

 cause immediate death. One hatched .\u-u-t Jjth. and the 

 young larva was about one-eighth inch in length and was dittiTcnt 

 from any I lesperid larva I had ever seen in bein- (ream white in 

 color. I 'nder the microscope it showed six or eiijit .small \> 

 like warts on each segment. The head was ol a hejit collee color 

 darker toward the front. It entirely devoured tin- egg shell. 



The eggs were of the usual form in the genus and t a pale greenish 



white color. I tried to ivar it on lawn ETass. which it al'-olutelv
