Is Eulepia Crihruni Double-brooded ? — Of late I have 

 been repeatedly asked the above question by my corre- 

 spondents; and persons wishing to take the species have 

 come to me asking if the second brood was out in August 

 and September. I cannot be positive ; but I believe the 

 idea of its double-broodedness is altogether a mistake. How 

 did the notion first originate ? Was it from the times at 

 which the insect is to be met with ? One correspondent 

 says, — " Surely there must be a second brood, as I have 

 taken it in Jane and again in August.'' I do not see, how- 

 ever, that its occurrence in these two months establishes the 

 fact of a second brood, for all who have taken the insect are 

 well aware that it is commoner in July than in any other 

 month. Of course a forward or backward season makes 

 some material difference in the time of its appearance. Did 

 any collector ever rear the moth in August from eggs laid in 

 July ? If so, my argument must be dropped. I have always 

 noticed that eggs laid in June or July — and 1 have not 

 .unfrequently found them upon the little stems of heather, 

 arranged in the neatest manner — soon produce larvae, but 

 they grow unusually slowly, and hybernate before being full 

 fed. We all know what strange and unlooked-for peculiarities 

 sometimes occur in the metamorphosis of any particular 

 species when thoroughly investigated and closely watched, 

 but in my mind it does seem strange that if there is a second 

 brood of Cribrum the whole transformation of such a brood 

 must be gone through in a month or six weeks, whilst its 

 duly recognized changes take a year to complete ; besides, if it 

 is double-brooded, is not such an occurrence a departure from 

 the habits and economy of the family to which it belongs ? 

 If the insect was common in June and again in August, and 

 not in the intervening month, we may reasonably suppose 

 there was a second brood ; but since July is the recognized 

 time of its appearance I do not think there is umch founda- 

 tion for supposing that the August specimens are produced 

 from the moths which emerge in June. It may be that the 

 larvae hybernate in different stages of growth, and indeed it 

 seems likely that a larva hatched in June would be nearer
