278 BRITISH BUTTERFLIES AND MOTHS 



The fore-wings are deep orange, with all the margins 

 black, and with three rounded tufts of silvery black 

 scales, two of which are near the inner margin, and the 

 third is intermediate between them near the costa. 



The larva is yellowish -white, with the head pale 

 brown. It feeds under the bark of the lime-tree in 

 winter and early spring. 



The perfect insect appears in July and August, and 

 sits on the trunks of lime-trees ; in St. James's Park it 

 may be collected in any quantity, and it is very pretty 

 to see these brilliant little insects walking leisurely 

 about, their white-tipped black antennae in constant 

 motion. 



FAMILY XIII. LITHOCOLLETIDJE. 

 LITHOCOLLETIS EO BORIS. 



(Plate XVI., Fig. 4.) 



This delicately-pretty insect seems widely distributed ; 

 it occurs near London, and in various parts of the south 

 of England, but seems commoner in the north at Scar- 

 borough, Darlington, and Newcastle-on-Tyne ; it does 

 not appear to have been noticed in Scotland nor in 

 Ireland. 



The expansion of the wings is about J inch. The 

 fore-wings are white, with an oblique golden-brown 

 band from the base of the costa reaching to the inner 

 margin a little before the middle ; beyond the middle 

 are four short black lines from the costa and one from 

 the inner margin. 



The larva, like many others of this genus, mines 

 blotches in the underside of oak leaves ; the mined part 

 curves downwards from the contraction of the loosened 

 lower skin ; the larva occurs in July and September.
