L. Caniola. — A larva, feeding on olive-green house-top lichens, with a taste for 

 clover, was secured to me for figuring by the kindness of Dr. Knaggs, on May 30th, 

 1862. Its head was dark brown, the body tapered a little at either extremity, the 

 ground colour brown, a thin blackish dorsal line slightly widening in the middle of 

 each segment ; the sub-dorsal lines composed of cuneiform orange-red marks 

 pointing backwards, and bordered laterally with similar marks of black, a whitish 

 spot almost touching the point of each wedge ; the sides rather paler than the back, 

 with a dusky lateral line ; the tubercles studded with brown hairs. 



L. Complanula. — Said to feed on lichens, though I have not found this the case 

 with the few I have reared ; the first I had, fed on oak ; others were taken on 

 buckthorn and dogwood, and this season one on clematis. This larva is of nearly 

 uniform thickness ; its colour above is a very dark bluish grey, the head, 

 plate on the second segment, broad dorsal line, and sub-dorsal, black ; the 

 body furnished with black tubercles and hairs, excepting an orange lateral stripe, 

 beginning at the fifth and ending on the twelfth segments, which encloses the 

 spiracles and extends to the pro-legs; the tubercles and hairs on the latter 

 segments being also orange colour. 



L. Complana. — I have also been indebted to Mi-. Doubleday for a specimen of 

 this lai'va, which throve well on lichens off fir trees, and was nearly full fed June 

 9th, 1862 ; the perfect insect appeared the end of July following. Its colour was 

 brown, with a very dark brown head and dorsal line. The sub-dorsal markings 

 consisted of oblong, somewhat reniform, dull orange-red marks, one on the anterior 

 of each segment, followed by an interval of the ground colour, and succeeded by a 

 whitish spot ; the usual tubercles and hairs dark brown. 



L. Stramineola. — This insect, as previously recorded in the Zoologist, M. Guenee 

 has pronounced to be a variety of L. Grlseola, after comparing a figure of the larva 

 with preserved skins of Oriseula in his possession. The larva was depicted June 

 24th, and the imago appeared July 30th following. 



The larva was brown, the head a darker brown, the back of the second, third, and 

 anal segments orange-red, as though the sub-dorsal naarks had become confluent ; 

 a similar red mark of an irregular trapezoid figure foi'med the sub-dorsal line on 

 the anterior two-thirds of each segment, a thin blackish line bordering them exter- 

 nally ; a thin dark brown dorsal line, interrupted on the second and third, and 

 terminating on the twelfth segment. Tubercles and hairs brown. 



L. Ruhricollis. — A tolerably abundant larva in beech woods during September 

 and October, feeding on the tree lichens. I also found it once swarming on a 

 lichen covered park paling, and reared a large number of the perfect insects, which 

 appeared during the month of May. The larva is rather elongate, tapering pos- 

 teriorly ; head blackish, body greyish and freckled with yellow ; a fine thread of 

 whitish, bordered with grey, forms the dorsal lino, which is white on the second 

 segment ; the sub-dorsal is a black line on the second, third, and fourth segments, 

 and on the remainder becomes an elongated black trapezoidal mark on the anterior 

 two-thirds of each, and terminates on the twelfth. The ground colour of the back 

 on each side of the dorsal line of the seventh, eighth, ninth, and tenth segments is 

 whitish ; the sides mottled with gi-eenish yellow and grey ; tubercles hairy.
