indeed it has been I'ound by ^Mr. S. J. Capper that if kept

Lah\a three-(niarters of an inch long, rugose, rather ilat- 

 tened below, slightly tapering from tail to head ; the latter 

 small and bifid ; dorsal region bufT-brown, brighter on the 

 head and three following segments ; a dark sub-dorsal — but 

 no dorsal — line (in these segments; at segment five the sub- 

 d<irsal lines cease, and a dorsal row of elongated dark brown 

 diamonds begins ; this contracts to a double dorsal line, but 

 is much darker on the hinder segments; the usual raised 

 dots black, emitting bristles ; the spiracular region pulled 

 and puckered, bordered below with a broad irregular stripe 

 of dark brown ; middle of the undersurface ochreous-brown. 



When younger less distinctly marked, warm ochreous- 

 brown above; chocolate-brown beneath ; a row of elongated 

 diamond-shajied markings slightly darker than the ground 

 colour on the middle segments : the usual dots blackish ; 

 along the s]Mracular region the dark and light shades of 

 brown meet in a sort of zigzag line. (Rev. .). llellius.j 



September till Ajtril or May ; but in confinement in a 

 second generation in August, or at uncertain periods ; on 

 CuUiina nihiiiria (heather), and Empctrv in nujrvm ; but in 

 confinement on chicKweed. sorrel, knotgi-ass. or even haw- 

 thorn I)uds. Abroad it is said to feed on Siihnn alhiini. 



Pita apparently undescribed, in a loose cocoon among the 

 leaves of its food, in confinement. 



The moth sits during the day upon rocks, sometimes under 

 the shelter of overhanging roots or herbagt , more frecjuently 

 low down behind tall grass, bramlilesor other rough herbage ; 

 almost always among the rock lichens, to which, both in 

 (clour and markings, it liears a most accurate resemblance.
