In copying the above tabJe, I have not considered the presence or 

 otherwise of traces of longitudinal strite on the anterior half of the 

 elytra, since, with a high power, these are found to be present in most 

 of the species, and appear to be subjected to considerable individual 

 variation. 



J^IOTES ON COLLECTING, Etc. 



A FEW NOTES ON MY 1910 COLLECTING. — I fouiid the past year 

 a poor one for butterflies, due principally, I consider, to the wretched 

 weather which prevailed during the greater part of the season. The 

 week-ends were particularly dismal, and often enough not an insect 

 would be met with on the wing. I did little with the butterflies 

 beyond rearing about a dozen Sati/nis seinde from wild larva?, and a few 

 Euclilue tarda mines from ova found on hedge mustard. I was much 

 more successful with the moths, though upon reference to my diary 

 I find very few were taken either at sugar or at light. Sallowing at 

 Chislehurst, on April 12th, disclosed that Taeniovaiuiia crutla was 

 abundant; T. t/othica, T. i)icerta, 2'. firacilis, and I'achnohia rKbricoxa 

 also putting in an appearance, though not in any numbers. On April 

 14th and next few succeeding days a nice brood of I'oecilocanipa poptdi 

 hatched out from ova obtained by pairing a ^ and 2 taken in the 

 pupa state the previous autumn at Haslemere. The young larva) did 

 not seem inclined to feed freely in glass-topped metal boxes, though 

 supplied with a variety of foodplants to choose from. Upon sleeving 

 them out they did much better, but after a short experience it was 

 apparent that they preferred sallow to poplar, birch, or oak, and 

 eventually all were brought through on sallow. They were a handsome 

 looking lot when fullfed, differing materially in colour and design, all 

 the varieties of the larvtB figured by Buckler being represented. The 

 larvae spun up in the folds of the leno, and the pupte were left in ftitii 

 when the sleeves were removed from the trees and brought indoors. 

 The moths commenced to emerge on November 8th (when five males 

 appeared), and continued with intervals to do so till December 2nd, the 

 first $ putting in an appearance on November 10th. Altogether 81 moths 

 were bred, but of these quite a number were crippled, due, I presume, 

 to their inability to escape readily from their cocoons. Doubtless it 

 would have been better to have removed the larvae, when nearly full- 

 fed, from the sleeves to a roomy breeding cage, and thus have afforded 

 them an opportunity of spinning up in rough stuff at the bottom of the 

 cage. Several of the pupa; are remaining over. 1 was successful also
