NOTES ON COLLECTING, ETC. 19 



and when I had ]\x<,t fii/ed my boxes, I came upon Pliigalia pilosaria on 

 the wing in scores, all flying round a dwarf holly bush in a hedge. I 

 had a man with a lamp with me, and fortunately we had a net each. I 

 had lo resort to my pocket killing bottle, and my man caught them 

 until my bottle was full, and we then had to give up. They swarmed 

 round the holly bush, but we could not beat any out. They ceased for 

 about five minutes, and then came again as thick as ever. I concluded 

 there were females about, but the most vigorous search failed to find 

 any trace. When I reached the inn and turned out my killing bottle, 

 there were 16 P. pilosaria, all freshly emerged specimens, which were 

 very variable. The result of my outing was 16 P. pilosaria, 13 11. 

 progeiiunaria, 27 ZT. rupicapraria, 2 Cheimatobia bruviata, and 2 Depres- 

 sarice {sp?). I do not consider this bad for the 31st of January ! The 

 nighr was still, warm, and bright moonlight. — B. Blaydes Thompson,

American Foodplants of British Insects. — To those interested 

 in the food plants of British insects, the following may be of some 

 service : — 



Aniphipyra tragopogonis, L. is recorded as feeding on the vine, by 

 Strecker. 



Heliothis arinigera, Hiibn. is recorded as feeding on the cantaleup 

 and cotton plant, by Strecker. 



Noctiia C. nigrum, L. is recorded as feeding on the maple, by 

 Thomas, and on the peartree, by Harrington. — T. D. A. Cockerell, 

 West Cliff, Colorado, U.S.A. 



Species double-brooded in 1889. — The fine weather in May and 

 June brought out the spring moths earlier than usual, and as a 

 consequence of continued fine weather for several wrecks, many early 

 species produced a second brood remarkably early in the season, and 

 ordinarily single-brooded species have had a partial second brood. 

 The second brood (I presume this was so) of Cidaria silaceata was 

 getting worn near Yarmouth (I. of W.) at the end of July and beginning 

 of August, as also was that oi Ephyra porata. On the 31st of August, 

 I found near Strood in Kent, fine specimens of Metrocampa margaritata 

 quite recently emerged. The second brood of Platyptilia gonodadyla 

 was out in the middle of August, and continued to emerge up to 

 the end of September. Of Melanippe galiata I took the second brood 

 during the last two days of July at Freshwater, and Aspilates citraria 

 began to appear about the same time. A second brood of Ettbolia 

 lineolata was out at Deal on the 6th of July. — I. W. Tutt, AVestconibe 

 Hill, S.E. 



Eupithecia togata TWO years in pupa. — I have just bred the 

 remainder of a lot of pupas of E. togata sent me in 1888. The greater 

 number came out during last April (1889). It is strange how many 

 Scotch pupce go over for two years before emergence. I have 

 previously had Scotch pup?e of Satur7iia carpini, Eupithecia venosata, 

 Emmelesta albulata and Heydenia auroinaculaia do so. This is the 

 more remarkable, as one would expect the higher temperature to which 

 they are subjected in the south would hasten their emergence, and it 

 suggests at once that many pupae in Scotland must normally pass two 

 years in the pupal stage. Last year these pupae were subjected to the
