PRACTICAL HINTS. 209 



11. — In early September, the blotched appearance of the leaves of 

 sallow betokens the presence of the larviie of Gclcrhia notatcUa. On 

 the same plant, and at the same time, the cones of (h-adlaria stii/ma- 

 tt'Ua (in their white silvery-looking cocoons, on the underside of the 

 leaves) are to be found. 



12. — The larva of (Tclechia scriptella is to be found feeding between 

 united maple leaves, in the early part of September. The larva 

 changes to a pupa, in a slight silken web in the folds of the leaf, 

 towards the end of the month. 



13. — Collect, in August and September, the seeds of gentian, I'im- 

 pindla saxifraf/ct, wild carrot, etc. ; place in flower pot, and expose all 

 winter. In July next year, you will probably breed Scmasia rii/illava, 

 (Ecophora flavin) aexdella and Asi/chna profwjtila. 



14. — " The larvffi of Euplt/wcia denotata (plmpinellata ) may be 

 found in scores on the seeds of Pimpinella sa.rifrai/a in September. 

 Some of the larvae were green when the seeds were green, but later in 

 the season, when the seeds were brown, the larvae were chiefly 

 brown" (Hodgkinson). 



15. — During the first week in September, the cases of Culeophora 

 iiuiiluti'lla, which are very like the dark seeds of Mdilotus, are to be 

 found on the latter plant. 



16. — In August and September, the cases of Coloopliora n'ilkin.w- 

 nella, C. liwoHipenndla and 0. paripcnella are to be found on birch. 

 The larvae hybernate full fed, but pupate next year without further 

 feeding. 



:]i\OTES ON COLLECTING, Etc. 



Notes from the Isle of Man, — The cold winds experienced here 

 during March and April, accompanied by heavy rains, completely 

 destroyed the sallows for collecting. During the early part of the 

 season, Taeniocampa (/ntJiica, T. ^tahilU, T. instabilis and T. rubrico.m 

 came freely to the bloom, but, after the first few days of storm, insects 

 were conspicuous by their absence. At the time of writing, flowers 

 of white pink are proving very attractive to Choerocanipa porcelluii, C. 

 elpenor and Diauthoecia capsincola. On the coast, I), caesia has 

 occurred sparingly at flowers of Silene maritima, and D, capsnpJtila has 

 been somewhat scarce. The latter insect was on the wing by May 

 13th this season, and D. caesia on May 28th. In certain localities, 

 Seti)ia irrorella has been abundant, while larvae of Polia ni{/rocincta 

 ( xanthomiata ) have been extremely rare. — H. Shortridge Clarke, 

 F.E.S., Sulby Parsonage, Isle of Man. June 15th, 1897. 



Peronea permutana at Barnes ? — i should like to ask a question 

 about the reported occurrence of this species on Barnes Common. 

 Stainton {Man., ii., p. 235) gives "New Brighton and Barnes Com- 

 mon." Gregson (Entoin., xiii., p. 46) says that " in 1851 he took 

 the insect at Barnes Common." Probably this was Stainton's autho- 

 rity for the statement. The species was, a few years ago, more than 

 once recorded from the same locality, by Mr. Gates, at the meetings 

 of the City of London Entom. Society, but I examined some of these 

 specimens, and found them to be the form of P. rarie/iana, which bears 

 a somewhat superficial resemblance in coloration to P. pervmtana. Has
