11 4: ENTOMOLCGY. 



add here that I have on several occasions found fhe pupae of C. vinula on 

 the stems of oak, concealed in its hard case.) With vis it is rare to find 

 the larvae of Ligustri stung with ichneumon, also the larva3 of S. ocellalus 

 generally free, but the larvae of S. populi were very much affected, more 

 especially the late brood. Speaking of this brood, with us, the colour is of 

 a deeper shade, and nearly all have beautiful pink spots. A very curious 

 instance of (I believe) ichneumon, occurred with me some time since. I 

 bred a pale specimen of S. populi; three weeks after I had killed it the 

 body fell oiT; it was filled with very small larvae, but what they were I do 

 not know. A study of the ichneumon tribe, I daily feel is more and more 

 interesting, and I hope this season to commence collecting them. Perhaps 

 you have a species with you that attacks 5. ligustri; it is certainly a curious 

 fact, although we abound with ichneumons in this neighbourhood, this 

 insect -should escape with almost perfect impunity, more especially considering 

 its large size and bright colour. — Idem. 



Camplogramma fluviata, Hub., a Geometra new to Britain. — One day last 

 September, my brother and I were just leaving Braunton Burrows after a 

 tiring and rather unsuccessful day's work, when my brother started a little 

 moth out of some dry rushes, which, after a short chase, he captured. When 

 on the wing we took it merely for a Scopula ferrugalis, but on looking at it 

 in the net, I saw it was a small Geometra, though what I could not pronounce 

 at the moment. When at home, on examining it again, I took it for one of 

 the smaller species of the genus Phibalapleryx, though I was by no means 

 certain to which species positively to refer it. This winter, on arranging my 

 insects, wishing to become certain as to the "name of my little capture, I 

 forwarded it to Mr. Stainton, who kindly informed me that it was Campto- 

 gramma fluviata, of Guenee, a species new to the British Islands. I dare say 

 this account will prove interesting to the entomological readers of "The Natur- 

 alist." — Mtjekay A. Mathews, Raleigh, near Barnstaple, March 15th., 1858. 



Guenee's notice of the above insect is as follows: — 



" Camp tog r a mma fluviata. Hub. — 280, 281. Treits, II, p. 55, et Sup., p. 

 207. Her. Sch., p. 175. Lah. 316. Led. 102. Larvae unknown.— Hab.— 

 Middle of France, Italy, Sicily, Central Russia in September. Always rare. 



Of this little species Hubner appears only to have given a figure of those 

 varieties having an interrupted band. Moreover it appears to me that even 

 the slenderness of this band is accidental, for I do not perceive any other 

 essential difference between this species and the following varieties. 



A. Median band paler, continuous, not narrowed, and of middling size; 

 subapical mark, simply oblique and not angulated. Hab. — North America. 



B. Median band as large as that of Gemmata and exactly of the same 

 form. Hab. — Middle of France." 



In "The Zoologist" for March, Mr. Doubleday points out the fact that the 

 above insect has been confounded in British collections, with a still rarer 

 moth, Phibalapteryx gemmata, Hub. The latter has been taken by Mr. 

 Standish, and Mr. Harding, of Stapleton; Mr. Newcombe, and our correspondent 

 Mr. Mathews, have taken the former during the last summer.
