NOTES, CAPTURES, &C. 



Singular appearance of Larva of N. 

 Camelina. — When collecting the larvae of M. 

 hastata on Thursday, 12th inst, I came across 

 a quarter-grown larva of N. camelina, alive, 

 with what appeared like a dozen Round bright 

 green eggs attached to its sides. The unusual 

 appearance of the larva caused me to box it, 

 and I placed it in my waistcoat pocket. — 

 At 7.30 the same day it still presented the same 

 appearance, but the food was withered. Next 

 morning, 12 hours after, on opening the box, 

 the body of the larva had entirely disappeared 

 except the thin dried skin, and singularly the 

 supposed dark green eggs were elongated to 

 their present size. The question I should like 

 to ask is, if the larva had been provided with 

 fresh food would the Ichneumons remained 

 longer in the round state, before assuming the 

 elongated form in such a short time. I enclose 

 box for your inspection and if of service 

 you can retain them. — John Harrison, 7, 

 Victoria Bridge, Barnsley, August 14th. 



[Probably the round bright green eggs 

 spoken of, were the larvae of the Ichneumons 

 in the act of emergence. We have noticed 

 others before, and they have very much the 

 appearance described. The pupae sent us by 

 Mr. Harrison, are without protecting covering 

 of any sort. Three of them are red and the 

 others black. We retain them till they emerge 

 that we may learn what they are. — Eds.] 



Mites. — Mrs. Batterby, of Cromlyn, writes : 

 "With regards to your last paper on Mites, 

 I fear I cannot agree with you, for I lately 

 opened a little box in which I had placed a 

 Polia, to be sure that it was disinfected. It 

 was with some other insects and I soaked it 

 in Benzine, having previously put a small 

 lump of Camphor and drop or two of Carbolic 



NATURALIST. 



Acid in the box, there was a mite running about 

 quite merrily (the white kind) utterly ignoring 

 all my precautions ! So much for Benzine and | 

 Camphor." 



[We can only say our own drawers are clear 

 of mites and weadopt no other precautions than 1 

 there named in the article referred to. We 

 keep a good supply of Camphor in the drawers, 

 and never see a mite there. When it gets 

 exhausted one sometimes appears. The speci- 

 men is at once removed to the Cyanide Jar, 

 and the Camphor renewed. We scarcely 

 think Camphor will kill mites, but with us, it 

 certainly prevents their app :arance. We 

 should be glad of the experie ice of others. 

 Now is the time when they are li <ely to appear, 

 and therefore now is the imp )rtant time to 

 adopt preventatives. — Eds]

Imago. — PI. 7- Pig- 2. Mc.le, female, and 

 underside. Fulvous with blacks )Ots and marks. 

 Under side : Forewing as above ; a row of 

 crescent-shaped black marks near the hind ; 

 margin, with silver spots insid i the crescent. 

 Sometimes only those near the tip are silvery, j 

 and more rarely they are all without. When 

 the whole row are silvery, there are generally 

 traces of a second row inside the first. Hind 

 wing, green, except a band :iear the hind 

 margin, and a small central spot which are 

 pale brown. There are about twenty silvery 

 spots, but there are no red spots between the two . 

 outer rows. 1 his is the best distinguishing 

 mark we know, between Aglaia- and Adippe. 

 The female is rather paler in cDlor.
