LEUOANTA COMMA. 27 



brown, dull ochreous-brown,or dingy greyish-ochreous, 

 varying but little ; a thin thread of pale ochreous edged 

 with dusky brown formed the dorsal line, on either side 

 of which was a space of dingy brown, followed by a 

 line of dusky atoms, and then a stripe of the ochreous 

 ground colour. The subdorsal line brown, edged ex- 

 ternally with blackish at the anterior portion of each 

 segment ; next to it, a thread of pale ochreous edged 

 with reddish-brown, then a broad stripe of ochreous 

 ground colour edged below with reddish-brown, and 

 again with pale ochreous in fine thread-like stripes ; a 

 broad brown lateral stripe followed, at the lower edge 

 of which were the black spiracles, with a broad pale- 

 ochreous stripe below them ; the belly and legs 

 ochreous-grey ; ordinary dots black when present, but 

 not visible in some specimens ; head brown, streaked 

 and mottled with blackish. The chief distinguishing 

 character by which this larva can be known from those 

 of L. impura and lithargyrea is the addition of the 

 extra line between the dorsal and subdorsal. (W. B., 

 12, 9, 64; E.M.M., I, 140, 1864.)

After waiting many years, I have at length had the 

 satisfaction of figuring the larvaB of this species, and 

 breeding the moths ; and now have the pleasure of 

 offering some account of the larva, and of returning 

 my thanks to the three friends who have helped me, 

 viz. to Mr. Howard Vaughan, for the first examples, 

 June 21st and July 5th, 1870, and again in June, 1871 ; 

 secondly to Mr. C. G. Barrett, for larvae in April and 

 May ; and thirdly to Mr. Henry Laver, in June, 1871. 



The chief food of the larva consists of the leaves of 

 Arundo johragmites, though it will eat, and is sometimes 

 found on, Phalaris arundinacea, as well as on other 

 coarse grasses growing amongst reeds in wet places ;
