"August. The species is on the wing during the whole of this moult. 



"September. Not infrequent through the greater part of this month 

 also. On the 25th of September I found larvae nearly fed up, whilst on 

 the 7th and 3ist of October I found a pupa of it." 



I have before me Mr. Comstock's records of the species from 

 1899 to 1908, from which it is evident that, with the exception 

 of the month of June, it is on the wing in the New York dis- 

 trict and within a radius of fifty miles from the centre of that 

 city from early May till the middle of September. In June he 

 took a single specimen twice, only once in 1899 on June 25th 

 at Van Courtlandt Park, New York City, and one on June 2ist 

 at Jamesburg in 1908. It appears, therefore, that there are four 

 broods, the first and second with a distinct interval, viz., the 

 month of June, whilst with the second, third and fourth there 

 may be overlapping. It ; .si not unlikely that the fourth brood 

 may be only a partial on. 



I have a long series all dated from St. Louis, Mo., where they 

 appear on the wing earlier in the year, viz., April i7th. On this 

 date I have four males and one female. In this locality the 

 interval between the first and second brood appears to be in the 

 latter part of May and the early part of June, for on and after 

 June 14, 1909, it was regularly on the wing to the end of July. 

 I have no specimens taken in August, but several in September, 

 the latest date being September 16, 1909. 



Mr. Frost sent me a nice series from Framingham, Mass., all 

 dated, where it occurs plentifully in July and August. No 

 doubt it also occurs earlier, but I wrote to that gentleman late 

 in the year. 



From Michigan (Oakland County) the dates are similar 

 to the New York district, but the females are peculiar, being 

 sooty black with a limited suffusion of deep but brightish blue- 

 scales. 



From New Mexico (Fort Wingate, Woodgate Coll.) my 

 specimens, a long series, start on the seventh of May, are on 

 the wing regularly throughout June and, I understand, also in 

 July and August. It is interesting that this is the only locality 

 that I can trace where there is no interval between the first and 

 second broods.
