This circumstance much facilitates the 
detection of the parasites. If one takes 
out of the water a stone on which there 
are cases of Phvyganiclae, those fastened 
with long threads readily attract atten- 
tion. No doubt more than one species 
of ichneumon occurs in the larvse of 
Phryganidte. For instance, Von Siebold 
possesses cases and larvae of Molanna cy- 
lindrica with considerably larger threads, 
and evidently larger parasites, yet the 
imago is still unknown. It seems highly 
probable that the same facts will occur 
in England as in Germany, and therefore 
it would be interesting to direct attention 
to the subject, and to try and breed these 
parasites. 
In breeding Phryganidae some care is 
necessary ; if the cases are brought out 
I of the water and placed in a glass they 
! almost invariably die; but the following 
method will be found more successful — 
take a bag of some transparent substance, 
place some switches in it, so as to keep it 
open, then put the Phrygauidae cases in, 
tie it up at the top, and sink it in the 
water, so that a portion of the bag lies 
above the surface ; in this way, with very 
little trouble and expense, one can suc- 
ceed in rearing the perfect insects. 
ESSAI MONOGRAPHIQXJE SUE LE 
GENRE COLEOPHORA. 
Premiere par lie. 
The above is the title of a paper by 
Monsieur Bruand D’llzelle, published 
in the ‘ Auuales de la Suciete Entomo- 
logique de France,’ for the year 1859. 
Owing to some delay in the transmission 
of the ‘ Annales’ from Paris to England, 
I had not seen the paper till I met with 
it at the end of last May, at Stettin, in 
the library of the Entomological Society 
there; I then felt that I could not com- 
fortably exist longer without it, and, in 
returning home, made a detour by Paris, 
so as to spend one day there, and bad 
thus an opportunity of obtaining all the 
volumes of the ‘ Annales ’ that were due 
to me. 
This paper contains the histories or 
descriptions of nineteen species of the 
genus Coleophora, viz. — 
1. Coracipennella 
2. Limosipennella 
3. Albigriseella 
4. Troglodytella 
6. Semilinearieila 
6. Liueariella 
7. Griseireticulatella 
8. Parmeliella 
9. Balloticolella 
10. Ballotella 
11. Binderiella 
12. Solitariella 
13. Adelogrammella 
14. Vulnerariella 
15. Albitarsella 
16. Conspicuella 
17. Vibicella 
18. Scorodouiella 
19. Argentipennella. 
I will go through these species seriatim, 
aud vvill endeavour to point out by what 
other names any of them are known to 
us in England.
