lacking' the white spots over feet and legs, and on the anterior and 

 posterior segments; on 19th and 20th four had passed the fourth moult, 

 and came up pale green, as did all the other larvae of that brood; on 

 29th the first one fixed itself for pupation, and pupated 30th; making 

 the whole larval period twenty-three days. 



On April 14th came a lot of eggs on parsnip. All the larvae of both 

 lots had been fed at first on fennel; later, on ]:)arsley also. On May 

 3d four of last larvae passed fourth moult, two coming up green, but 

 two black, one of them verv black, the bands almost excluding any 

 white, the other less so, the bands not so broad. The usual green was 

 changed to white or whitish. Part of the chrysalids were wood-brown, 

 part green. One imago only came from chrysalis this year, a female, 

 on May 29th, from pu]3a formed May 15th, and the rest hibernated, 

 giving imagos in March, 1884. Mr. Wright was surprised at hearing 

 of the rapidity of the stages of my larvae, inasmuch as some retained 

 by him from the lot received by me April 14th did not pupate till June 

 9th, or one month later than the last of my larvae. Why this should 

 be so I do not know, as the climate at San Bernardino is warmer than 

 in Virginia in April and May. 



The habits of these larvae were in all respects like those of Asterias. 

 They are sluggish at all stages, remaining long in one place, moving 

 merely to feed. 



Note. — While this paper was passing through the press, I received 

 from Prof J. J. Rivers, some notes on Zolicaon as it appears at his 

 residence, Berkeley, Cala. He says: " Here at the end of April the 

 first appearance of the butterfly takes place, and again in June come 

 fresh examples; and from that time till the end of August fresh speci- 

 mens occur frequently." 



Steps are now being taken by the American Entomological Society, 

 of Philadelphia, that will doubtless end in the endowment of a perma- 

 nent Curatorship. This will place the Society in the front rank in this 

 country and entitle it to the first consideration as a worthy beneficiary 

 for Entomological material. As a Section of the Academy of Natural 

 Sciences of Philadelphia the Society has the advantage of a fi*e-proof 

 building, the benefit of collections and library surpassed by none in 

 America, and, with their own and the Academy's, the most complete 

 Library of Entomological works, as well. These advantages with the 

 endowments left them by the late Dr. Thos. B . Wilson — which enable 

 them to publish their Transactions, and purchase desirable publications, 

 — will place them, so soon as the Curatorship is established, on a firm 

 footing.
