18 LITHOSIA STKAMINEOLA. 



which he assigns to it, of being a variety of griseola. 

 (J. H., 14, 7, 73 ; E.M.M. X, 69.) 



Two larvse which had been reared from eggs, were 

 received from the Rev. J. Hellins, April 29th, 1873, 

 feeding on lichens ; the smaller of the two sickening 

 for its final moult. This larva was three-quarters of 

 an inch long, rather stout in proportion ; the ground 

 colour dark slaty pinkish-grey, very faintly marked 

 along the sides with paler ; the subdorsal marks of 

 orange-ochreous were in front of each segment some- 

 what of a triangular form, with the angles rounded off, 

 pointing forwards ; from these a thin faint streak of 

 greyish -ochreous ran backwards to the end of the 

 segment, but scarcely to be noticed till beyond the 

 second tubercle, both tubercles interrupting it, the 

 second much the largest; the dorsal stripe broad, 

 faintly darker than the ground, which was itself blackish, 

 but it was dull black at the beginning, and there was a 

 black blotch on the side immediately in contact with 

 the orange-ochreous mark, so that these marks looked 

 as if on a short transverse black velvety band ; on the 

 back of the third segment was a conspicuous patch of 

 orange-ochreous, another on the front division of the 

 thirteenth segment ; the former partly divided by a 

 central black line, a little in front and more behind, 

 where it bore a small blackish-brown hairy tubercle, 

 on each side and more in front it was bounded by a 

 large dark tubercle, which gave a lichen -like character 

 to the form and colour of this patch. The same idea 

 was suggested by the hind patch of this ochreous colour, 

 which was only partly divided by a black central line ; 

 along the side there was an irregular stripe of a greyish 

 flesh-colour, interrupted by the row of sub-spiracular 

 tubercles, which was the middle of three rows along the 

 side, the lowest row being almost on the upper part of 

 the prolegs, and almost on the belly on the other 

 segments. The head black and brilliantly polished, 

 all the rest dull, either of a waxen or velvety appear- 

 ance ; all the ventral prolegs well developed, paler than
