This highly interesting insect has been described by Linn<eus, 

 but it has never been figured, and M. Pictet does not appear 

 to have been acquainted with it; and although Dr. Leach gave 

 it a generic name, it has never yet been characterized. There 

 is no specimen contained in the Linnaean Cabinet, and from the 

 size mentioned in the Systema Naturae it appears to have been 

 the male that Linnaeus described, which is much smaller than 

 the female, being only 6 instead of 8 or 9 lines in expanse. 



Chimarra is probably nearly allied to Hydroptila, but with- 

 out recent specimens it would not be safe to discuss its affi- 

 nities : those which I possess being much injured I cannot 

 vouch for the correctness of the form in the mentum, and the 

 labium also was too mutilated for description : I suspect that 

 the long hairs represented on the inferior basal nervure in 

 fig. 9. may be the cilia of the inferior wings transferred by 

 damp and pressure. 



My friend Mr. Dale first gave me a specimen of this insect, 

 which he took on the Dart near Spitchwick, Devon ; the Rev. 

 W. L. P. Garnons met with it in plenty near Ambleside, and 

 at Capel Cerig, Wales, the 11th of June 1832. I am also in- 

 debted to Dr. Stephenson for specimens, accompanied with the 

 following memorandum : " On the 7th of last June I took this 

 insect in abundance on dry stones in a small mountain stream 

 close by Rydal Hall, Westmoreland, the beautiful seat of Lady 

 Ann le Fleming." 



I have much satisfaction in adding a figure of the local 

 Eriocaulo7i septa7igulare{Jo'inted Pipewort). One of my objects 

 in visiting the Isle of Skyelast summer was to see this curious 

 plant growing, and I am happy in the opportunity it affiirds 

 me of acknowledging the many kindnesses we received from 

 Colin Elder, Esq., of Isleonsay, who directed us to the little 

 Loch where it was in flower, and pointed out to me the variety 

 with ten angles on the stalk. 



In a tour through the south-west of Ireland last July, Mr. 

 Haliday and myself observed the Eriocaulon in abundance, in 

 various lakes from near Oughterard to Roundstone in Con- 

 nemara.
