the Hunter Ncphele spoken of was swollen for 2nd moult, which it passed 

 two days later. Two Illinois JSiephcle passed 1st moult 8th March. To 

 the end some of the Hunter Nephele were in advance of all, and some of 

 the Illinois examples lingered behind all. The stages of Coalburgh Alope 

 were as follows : 



1 st moult passed 7th March. 



2nd " " 21st " • 1st to 2nd — 14 days. 



3rd " " 14th April. 2nd to 3rd — 24 " 



4 th " " 2nd May. 3rd- to 4th— 18 " 



In chrysalis 26th " 4th to chrys. 24 " 



Imago issued 9th June. chr. to imago 14 " 



Of Hunter Ncphele I firj.d no notes, but in 1877 the stages were 

 1st moult to 2nd — 23 days. 

 2nd " to 3rd — 14 " 

 3rd " to 4th — 14 " 

 4th " to chry.— 28 " 

 Chrys. to imago — 14 " 



Of Illinois Nephele the stages were : 



1 st moult passed 8th March. 



2nd " " 21st " 1st to 2nd — 13 days. 



3rd " " 9th April. 2nd to 3rd — 19 " 



4 th " " 26th " 3rd to 4th— 17 " 



In chrysalis 17th May. 4th to chry. — 21 " 



Imago issued 30th " chry. to im. — - 13 " 



The eggs of all these forms are alike, not to be distinguished from 

 each other. They are conoidal, truncated at top and slightly arched ; 

 marked by about 18 vertical ridges running from base to top, the spaces 

 between excavated roundly, and crossed by fine stria? ; the top is covered 

 with shallow cells, the outer ones irregularly hexagonal, the inner long and 

 narrow about a central oval cell. 



Nor can the larvae of these forms be distinguished from each other up 

 to second moult. The young, of first stage, are very peculiar and quite 

 unlike what they become after first moult, as well as unlike all other 

 Satyrid larvae which I have bred. Under the microscope they look like 

 the vertebrae of a fish, by reason of the many rows of long hooked bristles,
