of May. In the year 1893 Mr. Kobt. Adkin reared a partial

 rather quadrate, brownish-ochreous, dusted with black ; face 

 flattened, paler; general colour brownish-ochreous tinged 

 with darker upon the back ; dorsal line greyish-ochreous, 

 slightly enlarged in the middle of each segment ; subdorsal 

 lines exceedingly threadlike, composed of minute white dots ; 

 spiracles black or dark brown ; usual raised dots black ; on 

 the undersurface are numerous longitudinal pale brown 

 markings and a broad central whitish stripe, edged on each 

 side with grey, and enclosing a brown line ; underside of 

 legs and prolegs dull green. 



Or — Ochreous, with outlines of dark purplish-brown dorsal 

 diamonds, especially from the fifth to the ninth segments ; 

 dorsal line dark purplish-brown, darker on some segments, 

 and enlarged into a blotch particularly on the sixth, seventh, 

 and eighth ; sides shaded with brown ; a conspicuous row of 

 blackish spots lies above the faint brown subdorsal line ; 

 usual dots and spiracles black ; on the undersurface is a 

 broad pale ochreous stripe margined with dark grey.

 brown on the back ; dorsal line dark greyish-purple, enclosing 

 a whitish thread, and bisecting a series of, often indistinct, 

 paler diamonds outlined with dull black; undersurface dull 

 reddish ; central stripe dusky-white, enclosing a reddish 

 line.
