ACOSMETIA MORRISIl. 257 



name it after me, as the discoverer of the insect. The following is a 

 general description : — 



"Pale straw-colour approaching to silvery white, the upper part of 

 the wings very faintly streaked with narrow brown lines, diverging 

 (from an obscure black dot ?) towards the margin, which is of the same 

 colour with the rest of the wings, from which tliey are hardly dis- 

 tinguishable ; the wings underneatli* are divided transversely by a 

 faint waved brown line, and the margins clouded with the same colour. 

 The insect is an inch and half a line in width from tip to tip, and is 

 not thick bodied, though belonging rather to that class than to the thin 

 bodied. The first specimens I took were met with, several years ago, 

 near Charmouth, Dorsetsliire, beyond a lime-kiln on the cliff on tlie 

 east side of the little river Char. I believe individuals may be taken 

 thei'e every yi-ar, though they certainly are nor, common. They rise 

 up from the grass and tiy well and straight, m o iag disturbed m the 

 daytime, some viiar. af er t le manner oi P ■i<'- ij' "in," ("' .i " ." ^-

 remember tlie exact time of their appearan e, but it was aoout the 

 middle of summer, and they remained 'out' a considertible time. Mr. 

 Dale has also taken specimens at the same locality.

 "April 4th, 1837. 



N.B. — In comparing the above description of morrisii with 

 bondii, it should be borne in mind that the latter never flies by 

 day, at least that is the experience of all who have collected on 

 the ground with whom I have come in contact ; and also that 

 the grass to which bondii is attached is dark green in the hottest 

 summer. 



Messrs. Humphreys and Westwood (vol. i. p. 244, and plate, 

 1843) give a figure of an insect with narrow pointed wings, pur- 

 porting to represent morrisii. The wings are all four of the same 

 colour, namely, pale ochreous whitish, toned with pale reddish 

 brown towards the margins, with two faint transverse lines, 

 but no dotted second line. The letterpress says that the fore 

 wings, hind wings, and body are all pale straw-colour, and that 

 the costa is slightly brownish. 



Curiously enough, the Eev. F. 0. Morris himself published, 

 in 1872, his popular illustrated work on ' British Moths,' in 

 which he made no mention whatever of morrisii, but gave an 

 excellent figure of an insect which he called bondii, and said 

 that it occurred at Folkestone. He apparently was unaware 

 of the Lyme Regis locality discovered in 1863 by my old friend 

 Percy Wormald.
