until it arriveg at an elevation which, by giving a shortened time 

 for the growth of the larva by the late melting of the snows, or 

 by decreasing its nourishment by stunting the food-plant, again 

 dwarfs the species down to, or below, the average of the plains.

A SMALL COLLECTION OF SWISS NEUROPTERA. 

 By W. J. Lucas, B.A., F.E.S. 



With his usual kindness Dr. Chapman handed over to me 

 the Neuroptera he took in Switzerland in July and August of 

 the past summer. Though few in number there were amongst 

 them representatives of four of the neuropterous suborders. 



TerijIdi A. — Dictyopteryx alpiim, two specimens, Saas-F6e, 

 19th to Slst July. 



Odonata. — Sympetrum striolatum, one female, Zermatt, 9th 

 to 16th August. S. fonscolomhii, three males, Zermatt, 9th to 

 16th August. 



Planipennia. — Panorpa vulgaris, one female, Glion, 2nd to 

 5th July ; also one male and three females, Vissoye, 7th to 17th 

 July ; P. vulgaris, which is common in Switzerland, is struc- 

 turally only a form of our P. communis. Ascalaphus coccajus, 

 two females, Saas-Fee, 19th to 31st July. 



Tkichoptera. — Drusus nigrescens, one, Saas-Fee, 19th to 

 31st July. Sericostoma pcedemontanum, one, Saas-Fee, 19th to 

 31st July. 



Mr. K. J. Morton kindly assisted with some of the identifi- 

 cations. But one species, Sympetrum striolatum, is represented 

 in Britain. 



NOTES AND OBSERVATIONS. 



Rhodometea (Sterrha) sacraria in South Devon. — The speci- 

 men recorded by Mr. H. M. Edelsten {antea p. 250) is a male and not 

 a female, as there stated. The mistake arose in the press. 



Angerona prunaria in September. — One individual of a brood 

 of eighty larvae, reared from eggs laid by a bred female in early June 

 last, became full grown and spun up about September 15th. A 

 female moth emerged on September 28th. All the other larvae 

 remain of the normal size for the time of year, and will no doubt hyber- 

 nate in due course. — J. B. Morris ; 14, Ranelagh Avenue, Barnes. 



NoNAGRiA NEURICA IN BRITAIN. — During July we captured in 

 Sussex a Nonagria which we at first believed to be arundineta and 

 recorded as such in August ' Entomologist,' but upon a closer 

 exainination, not finding the specimens to agree with those from 

 Kent, Cambs, and Norfolk, we sent them to Mr. Edelsten, who replies
