LASIOCAMPA QUERCUS. 57 



structure and disposition of hairs, it will suffice to 

 mention the characters which chiefly distinguished 

 these larvae. 



The general colour of the hairs above the subdorsal 

 stripe was of a rather light brown, but below and on 

 the ventral surface darker brown. Along the sub- 

 dorsal region there was a large triangular mark or 

 streak of white with black centre. Besides the much- 

 interrupted white subdorsal streak on the third and 

 fourth segments, there was just above it on the black 

 rings a whitish oval or shuttle- shaped mark with a 

 black spot within it near its anterior margin. The 

 white subdorsal stripe appeared to be continuous on 

 all the black velvety parts of the body that were not 

 hidden with hairs, for these interrupted it from view 

 about the middle of each segment ; from the subdorsal 

 stripe oblique white streaks flowed backwards near the 

 beginning of each segment ; those beyond the thoracic 

 ones were spotted or mottled with dull red below. 

 Above the legs were two ivhitish and red dull stripes, 

 with indications of an interrupted middle line between 

 them. The oval spiracles were white. (W. B., Note 

 Book II, 185.) 



On the 25th of August, 1875, a pair of this species 

 in cop. were brought to me, and the female laid a great 

 number of eggs all loose in a box. 



The egg is large, of a regular oval form, smooth 

 and shining, of a pale drab colour, irregularly blotched 

 with light brown. A few days before hatching they 

 become wholly brown, and after the extrusion of the 

 larva the shell regains its previous colouring. 



The larvae were hatched on the 12th of September, 

 and were a quarter of an inch long, and hairy.
