16 ANTHROOERA BXULANS. 



probably covered with snow from November to April 

 each season." 



The egg of exulans is of large size for that of the 

 insect, and of long, cylindrical, round-ended shape, 

 having a depression bending inwards rather irregularly 

 on one side ; the shell is very thin, and very slightly 

 reticulated all over, in colour ochreous-yellow, changing 

 to orange-ochreous, and finally to dark greenish slate 

 colour, very shining from the first to the last. 



When first hatched, the larva is a plump sausage- 

 shaped little creature of yellowish olive-green colour, 

 most minutely dotted with black, having a row of sub- 

 dorsal dull orange blotches, a black shining head, the 

 usual warts black, each with a longish rough, but 

 pointed, black bristle, the skin rather pubescent. 



After moulting, the minute dots not being so black, 

 it appears much paler coloured, more of a drab tint 

 showing dark subdorsal markings, but as the larva 

 grows, when it is about three weeks old, it is dark 

 olive-green on the back, with the sides lighter green, 

 and it has a subdorsal row of dark brown tubercles, 

 with a faint stripe of yellowish below them, the bristly 

 hairs blackish-brown. 



Just before it begins to hibernate about the 10th of 

 September, it has grown to a length of nearly two 

 lines, and is of very stout proportions, the colour dark 

 olive-green with an interrupted black subdorsal stripe, 

 below which at the end of each segment is a transverse 

 oval spot of orange -yellow, the surface of the skin 

 generally being much covered with little fascicles of 

 black hairs. 



In the following spring, after moulting, it is soon of 

 the length of three and a half lines, and its colouring 

 is a little fresher and darker; by the time it is from 

 four to five lines in length, the back and sides are very 

 dark green, and so much covered with black bristly 

 hairs radiating from tubercular eminences as to appear 

 blackish-green in comparison with the belly which is 

 olive-greenish-yellow, the dorsal marking is velvety-
