three or four days before their backs assumed the dark maroon colour. One larva is 

 dead, the others have all formed into chrysalides, but luithout burying in the earth. 

 I covered them with earth two or three times, when they were more than half formed 

 into pupae, but in a few hours they were on the surface again ! I am told this 

 Sphinx has been named " Langia zeuzeroides," but I first discovered it, and sent the 

 first specimen to England by Dr. Jerdon, and the only specimens in Major Lang's 

 collection (a male and female) were given him by me. — Wm. Chas. GtOTT, Colonel,

Re-occurrence of Setodes interrupta in Worcestershire.- — Visiting the banks of 

 the river Teme on August 6tli, in the forenoon, in search of Trichoptera, I was so 

 fortunate as to meet with a little colony of Setodes intemipta. The creatures were 

 at rest, exposed on the leaves of herbage, especially nettle, in the shadow of willows, 

 and presented a striking and attractive appearance. When disturbed, they darted 

 off with a shufiling, zigzag gait towards the earth. From the condition of the 

 specimens, which are mostly rather worn, the i-ight time to look for the insect should 

 be from the middle to the end of July. I secured twenty-seven. If any Neuropterist 

 desires the species, I shall be happy to send him a type or two. — J. E. Fletcheb,

Phryganea obsoleta in Ireland.— -The Eev. A. E. Eaton captured a fine S of 

 P. obsoleta (not hitherto recorded from Ireland), at Limerick, on the 16th ult. The 

 species is very variable ; this individual has the anterior wings prettily varied with 

 brownish. Ireland has never yet been systematically worked for Trichoptera, and 

 there is no knowing what good things may occur there. The few results of Mr. 

 Eaton's not specially entomological tour have raised my expectations considerably.

Note on Jlebrus ruficeps, Thorns. — This little creature will probably prove to be 

 rather widely distributed in Britain, at least in tlie North. I took it in 1870 in Dr. 

 Sharp's orii,'inal locality for Lamproplax in Dumfries-shire, as well as in the place 

 where Dr. Reuter and I found it here. At the time, I took it to bo a brachypterous 

 or undeveloped form of //. pusillus, and indeed did not examine it very closely. It 

 is to be found by shaking very wet Sphagnum, at the edges of ponds and marshes. —

Note on the Natural ITistortj of some Aphidce. — In the grass-root lice {Pem- 

 phigus, Schizonenra, Avigcla), I find wonderful alternate generation, for while the 

 aiirian Pemphigi (bursarius, ajfinis, &c.) in the winged state lay agamous lice fur- 

 nished with a rostrum, the subterranean Pemphigi {Boyeri, ccerulescens) lay sexual 

 young without any rostrum ! ! Are the grass-root lice the winter form of the poplar- 

 gall lice, similar to the Phylloxera on the vine ? It is very difficult to follow the 

 migi-ation of such small creatures, yet after Adler's discoveries about Cynipidce all 

 is possible, and some day wc must find out what becomes of the winged Pemphigi, 

 which disappear in the autumn and arrive in the spring ; — a mystery hitherto in- 

 explicable, although De Geer, v. Grieichcn, Bossuet, Kaltenbaeh, Reaumur, and 

 others followed it up for many years without success. — J. Lichtenstein, Mont- 

 pellier : 31*^ Jt^ly, 1877.
