58 LASIOCAMPA QUERCUS VAR. OALLUN2E. 



Lasiooampa quercus, var. callunj;. 

 Plate XL VII, fig. 3. 



On the 8th of June, 1868, seven of these larvae were 

 sent me by Mr. Doubleday; they were feeding on 

 hawthorn. 



The general colour of the hairs above the subdorsal 

 region was a bright golden brown, darker or lighter 

 in individuals, but very bright and glossy ; below, on 

 the sides, the hairs were deep blackish-brown, the 

 ventral surface still darker brown and nearly black. 

 The triangular subdorsal mark on the second segment 

 was just edged above with white, but was chiefly bright 

 red, and the same with the ear-like subdorsal marks, 

 of which one was about the middle of the third and 

 one on the fourth segment. 



There was no subdorsal strife, but only a row of 

 subdorsal spots, one behind each segmental division; 

 these spots had much the character of a triangular 

 oblique streak of red, having in some individuals the 

 anterior apex white, but in others wholly bright red. 

 There was only one stripe above the legs; this was red 

 and only obscurely visible. The oval spiracles white, 

 with a fine hair -like black line down the centre, marking 

 the aperture. (W. B., Note Book II, 186.)

Plate XL VIII, fig. 2. 



On the 11th of June, 1874, I found a full-grown 

 larva at rest on a branch of birch at Ems worth ; it was 

 about an inch and three-quarters in length, rounded 

 above, rather flattened beneath ; the ventral prolegs 

 rather sprawling ; the head full and rounded, but 

 decidedly smaller than the second segment ; the body 

 of uniform size or nearly so, though when stretched
