34 GNOPHRIA RUBRICOLLIS. 



Gnophria RUBRICOLLIS. 

 Plate XLII, fig. 2. 



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 posteriorly ; 

 head blackish, body greyish and freckled with yellow, 

 a fine thread of whitish, bordered with grey, forms the 

 dorsal line, which is white on the second segment, the 

 subdorsal 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 greenish-yellow and 

 grey ; tubercles hairy. (W. B. ; E.M.M. I, 49.) 



Cybosia mesomella. 



Plate XLII, fig. 3. 



On two or three previous occasions, I kept a larva 

 or two alive from summer till after Christmas, having 

 fed them on sallow leaves, green or decaying ; and last 

 spring I managed to retain one even until the new 

 sallow leaves were out again, but it would not resume 

 feeding after hibernation, and so died; it was then quite 

 half an inch in length; in colour a velvety-black all 

 over, and covered on every segment, save the head and 

 second, with tufts of singular spatulate dark grey 

 hairs. I should much like to procure some sort 

 of food on which this species would feed up, for they 

 would never take to any sort of lichen I gave them.
