hotbro the middle of May, Init they do not become abundant before the 

 last woi'k in tiu- month ; the first females appear about ten days later than 

 the males but are still rare at the beginninj;' of June, although they dis- 

 appear toward the end of the numtii or early in .Inly. 



The earliest buttertlies ot' the next brood, again C p. negleeta, appear 

 about the first ot' July anil continue to emerge from the chrysalis until the 

 first of August; they become abundant by the middle of July, although 

 the males are often still greatly in excess in tiie latter half of the month, 

 and in spite of their great delicacy these insects may s^till be seen in tSep- 

 tember. This brood does not seem to be so abundant as any of the 

 preceding, and especially as the very first, the reaijon being that sonic of 

 the earlier ehrysalidsdo not give birth to the butterfly until the succeeding 

 year : thus Dr. Dimmock obtained a caterpillar on Vacciniinn which 

 pupated on June 17th, and so should have emerged as a member of this 

 July brood, but which did not give the butterfly (formlucia) until the winter 

 (ii\ a warm room). So Abbot in (tcorgia bred one of the forms in 

 March from caterpillars which went into chrysalis the last of the preced- 

 ing April. These facts with the relative numbers of the different broods 

 and the experience of Mr. Edwards in West Virginia, to be mentioned, 

 would seem to indicate that the spring brood is made up from chrysalids 

 of all the broods of the preceding year. 



I have given above the facts regarding the appearance of this insect as 

 known to me in New England, anil mainly as written many years ago, so 

 as not to confuse the account by statements of the results of others out- 

 side of New England. But it cannot be said that the account formerly 

 given by me (Can. ent., viii : 01) is as there given w^holly satisfactory, 

 or accords fully with what is known elsewhere. That all the different 

 forms of Cyaniris, in eastern America at least, belong to a single species 

 is as good as proven ; but that their relation to each other is as simple as 

 I formerly supposed is by no means sure. If, as there regarded, negleeta 

 is only and always the child of eggs of the same season, and the other 

 forms of eggs of the pi-eceding season, how does negleeta appear so 

 early? There is a bare month between its first appearance and the first 

 appearance of lucia. And yet the females never appear among the first, 

 and if we are to look upon the earliest negleeta as born of eggs laid the 

 same season then in a comparatively cool part of the year all the transfor- 

 mations must take place within three weeks. Now in West Virginia Air. 

 Edwards has found it to take more than seven. The only alternative 

 that seems to be open is to regard at least the earlier negleeta as a part of 

 the first brood, which then becomes trimorphic. 



This is the view of it, essentially, which is taken by Mr. Edwards, who 

 has had a far wider experience in rearing this insect than any one else. 

 The first spring form in West Virginia (where lucia proper does not
