368 THE ENTOMOLOGIST. 



The Rev. H. H. Ciowe and myself have collected a number 

 of larvae, supposed to be those of D. capsophila, in the 

 locality where D. Barrettii also occurs, and I am not without 

 hopes that there may be both species among them. I have 

 heard doubts expressed by more than one Entomologist of 

 note as to whether D. Barrettii is a true Dianthcecia at all, 

 but should D. Barrettii and D. capsophila be reared from the 

 same larvae this will dispose of the question of genus and 

 species together. — TV. F. Kir by ; Dublin, October 16,

Life-history of Hydrocampa nymph(Balis. — Having found 

 the larva of Hj^drocarapa nymphsealis feeding on the common 

 star-wort (Callitriche verna) on the 8th of June, I thought a 

 few notes on its habits would be interesting to some of your 

 readers. I found it very common in all the muddy pools in 

 Epping Forest, where its food-plant was growing. When 

 very young it forms itself a case with a piece of rush, and 

 fastens itself to the plant on which it feeds with fine threads. 

 I took some of the larvae home, and put them into a glass 

 vessel, so that I could watch their changes. It lives entirely 

 under water, and as it grows larger it cuts itself a case out of 

 the leaves and joins them together, and floats about in it 

 like a boat; it puts its head out of its case, and with its fore 

 legs draws itself from leaf to leaf The larva is dirty yellow, 

 the head black ; on each side of the 2nd, 3rd, 4tb, 5th and 

 6th segments there are four air-cells, which look like small 

 glass balls. They assumed the pupa state in their cases, 

 and appeared in the perfect state on the 10th of July. —

Occurrence of a Fumea [F. crassiorella, Bruand) neiv to 

 Britain. — I have bred several specimens of a Fumea this 

 year which proves to be F. crassiorella, Bruand. The males 

 are larger than either F. nitidella or roboricolella, to which 

 group they belong. The female is also larger and more 

 obese. 1 have had males in my cabinet for some time, but it 

 was only this year, by breeding the female, that I was 

 enabled to make out the species ; there are good figures in 

 Bruand's ' Monograph,' fig. 68, a male, b female, plate 2. —
