124 LEPIDOPTERA. 



June and •luly, on the outside of stiff' leaves of Ttipho 

 Intifolia, where it eats itself out a straight gallery anionj,' 

 the leaf-cells, down to the root. (Pastor Mussehl.) 



Pupa elongated, claj'-yellow ; in the larva cavity. (Pastoi- 

 Mussehl.) The preparatory states do not seem to have been 

 observed in this country. 



So far as I know this moth is never seen at large in the 

 daytime. It is exceedingly local and rather scarce, inhabit- 

 ing only the larger fens, and in them only the wettes-t 

 portions, and the margins of the broads and rivers ; it flies 

 at night, often over the water of the rivers or fen-drains, 

 and is very conspicuous in flight from the whiteness of 

 its hind wings. I have myself only captured it toward 

 midnight, when it will come, in hesitating fashion, near to a 

 strong light. It appears to have been first taken in those 

 Islands in 1854, when a specimen was secured at Horning 

 Fen, Norfolk, by i\Ir. Buxton ; this was recorded under the 

 name of Chilo oUusrllutt in the Entouioloijist's Annual, 1856. 

 The name was shortly afterwards corrected by M. Guenee. 

 From that time to the present it has been taken in small 

 numbers in that locality or the neighbouring Ranworth Fen, 

 also at Wicken Fen, Cambridgeshire ; and by Mr. Eedle 

 when employed by Lord Walsingham, at the riverside, 

 Lakonheath, Suffolk. So far as is known it is confined, with 

 us, to these three counties. Abroad it is distributed, in 

 suitable spots, through Holland, North Germany, Lower 

 Austria, Hungary, Galicia, Roumania, and Southern Russia. 



Genus 5. CHILO. 



Antennae simple, slender, short ; tongue very small ; 

 labial palpi pointed, porrected, thin, more than thrice the 

 length of the head; maxillary palpi also elongated; scales 

 on the forehead projecting into a ridge ; fore wings of the 

 male broad, oblong, retuse ; of the female longer, pointed ;
