222 THE entomologist's record. 



Sesia MY(tp,i:FoKMis ON pKAR. - Si'siu iiii/iifiai'foriilis is said by some 

 authors to ft^ed in pear, as well as apple, stems. 1 have collected 

 many hundreds, but have never found a trace in pear wood, but in Mr. 

 Fitch's garden, at Maldon, the ancient pear-trees are riddled, just as 

 Newman records, in the trunk itself. The trees are not trained, but of 

 full natural size, and very old. 1 think Newman must have seen these.

Larv.e am> cocoons t)F Plusja monkta at P)iDK0K0L'(iH.- -On June 

 5th 1 had an opportunity of spendin.i,' an afternoon in the l^eautiful 

 garden of my mother's home at P>idboro\igh, near Tunbridge Wells. 

 While admiring the luxuriance of a particularly line herbaceous border 

 I was stnick by the unusual appearance of one of the leaves on a plant 

 of Jh'l/)hinii(iii, and a closer scrutiny was rewarded by the discovery of 

 a nearly full-fed larva of Plnsia uumeta. Further search revealed three 

 more larv* and no less than twenty-four cocoons of a rich golden silk, 

 attached to the under surface of the leaves. During the last few 

 years that 1 have lived at Bidborough I have always searched the same 

 plants indefatigably though in vain, so that it is the more curious that 

 I should have been successful on the occasion of a flying visit like the 

 present. — H. W^ Shkpheard-Walwyn, ]\[.A., F.E.S., Dalwhinnie,

COLIAS HYALE HIBERNATED AND BRED. Durlug AugUSt last year I 



obtained several wasted females of this species, and confined them 

 over clover plants in the sun, for the purpose of obtaining ova ; these 

 were deposited very sparingly, and the total number obtained was 

 only a dozen. On hatching, the young larvae were fed upon white 

 clover, planted in a pot, and kept in a cool conservatory ; they fed 

 slowly until the end of November, at which period they evidently 

 commenced to hibernate, spinning pads of silk on the upper surface 

 of the clover leaves for that purpose. I counted ten larva" at this 

 period ; these, I presume, had done their best to imitate the natural 

 conditions under which the species hibernates, but these did not strike 

 me as exactly ideal. Tn the first place, the clover leaves closed up 

 each evening, and opened in the morning, and thus fixture of position 

 was not obtained ; and then the leaves themselves usually dried up or 

 decayed during the winter, with the result that a larva hibernating on 

 a decayed leaf would pro.bably have got mouldy. 1, therefore, took 

 nine and put them in a large chip box, covered with muslin, and 

 stood it on a ledge in the conservatory, where I could keep it at a 

 temperature of from 82 to 4.5^ during the winter ; the tenth larva I 

 left undisturbed on the clover plant. The result proved as T antici- 

 l)ated. On December 2oth the lai-va on the clover had developed a 

 patch of mould, which proved fatal, whereas those in the chip box 

 were quite healthy. Towards the end of February the weather got 

 warmer, and, on the 2()tli, I noticed the larvae were moving about, and 

 accordingly placed the chip box containing them on a plant of growing 

 clover, and found that by the 2Hrd all except one had commenced to 

 feed. This specimen showed no signs of eating, and in a few 

 days was dead. -ludging that now they were started from their 

 hibernation it would be advisable to keep them fairly warm. I kept 

 the conservatory at a temperature of from 40 to 55' . They fed 

 slowly each day, chiefiy during the sunshine. During March, in 

 changing them from one plant to another, one larva was dropped be-
