in the first it inhabited, is so curious, that I shall copy 

 Treitschke's remarks. " Surrounded by water as the larva 

 is that cannot be very easy ; it overcomes the difficulty hove- 

 ever, in the following manner : it cuts a piece of the stalk 

 which incloses it, the length of its body ; this piece of stalk 

 then becomes a portable case for it, in which it crosses the 

 water without wetting itself, for it has taken the precaution to 

 close both ends. When arrived near a stalk which suits, it 

 thrusts the fore part of the body out of its case, climbs up 

 against the stalk, dragging the case after it, and attaches it 

 there to the same place that it has chosen to introduce itself 

 into the stalk ; so that it is secure from all danger during the 

 period of its passage from one reed to anotiier." 

 The following are recorded as British species: 



1. forficellus Thunb., Wood, ;?/. 48,/ 1523.— hirtai/aio. S •— 

 consortella Hllb. pi. 32./ 220 S- 



June and July flying amongst sedges and Iris Pseudacorus, 

 sides of canal at Paddington and banks of the Thames ; sides 

 of ponds Kensington Gardens ; Epping Forest; Norfolk ; and 

 Whittlesea Mere. Caterpillar feeds in stalks of Poa aquatica. 



2. lanceolellus Hub. pi. ^3.f. 296 ? .—Curt. B. E. pi. 727 ? . 

 Never having taken this insect, although I have met with 



multitudes of C. forficellus, I agreed with Hiibner in consider- 

 ing them as distinct species, but they are stated positively to 

 be the sexes by M. Moritz. 



3. fumeus //aTO. — Wood, Jig. 1 524^ ^. 



June, Norfolk, amongst reeds, Mr. Skrimshire; Whittlesea 

 Mere and near London. 



4. punctigerellus Step. — Wood, Jig. 1525 S- Very similar to 

 the male of C. gigantellus. 



" Taken near \Vhittlesea Mere in July." Wood. 



5. gigantellus Hiib. 8. 53 ? .—Goda. pi. 267. f.'l $ ^ -con- 

 voluta Fab. — Wood^sjig. 1527 is not this species, it is more 

 like C. Phragmitellus. 



June on Hackney Marshes, Mr. Hatchett ; July, Whittle- 

 sea Mere, Mr. Dale. The Caterpillar lives in the young stalks 

 ot'Arundo Phragmites from the end of May to the end of Aug. 



6. caudellus Li7in. — acuminelja Hilh. 41. 284 ?. — mucro- 

 nellus Goda. pl.2S3.f. 1 c? ? • Wood's Jg. 1528 is not 

 Hiibner's insect, but probably a wasted variety of No. 1. 

 June, woods near Dartford and Erith, Kent, amongst Iris 



Pseudacorus. 



7. Phragmitellus Hub. 43. 297 S- 298 ? .— rhombea Haw. — 

 1 have never seen a specimen so light as Wood'sjig. 1 526, and 

 there ought to be a dark dot on the disc of each upper wing. 

 June and July amongst reeds, on which the larvae feed, 



Whitdesea Mere^nd Norfolk, Dr. Skrimshire.

 Esq. for the Star-headed Thrumwort, Adinocarpus Dama- 

 suniuiii.
