110 TIIE CANADIAN ENTOMOLOGIST. 



For the first few days the specimens captured will be found to be nearly all 

 of the male sex, but after this the females begin to appear and both sexes 

 are found together during the remainder of their short season of life which 

 does not usually extend beyond the first week in July. Sometimes an odd 

 specimen may be taken later than this, but it is always battered and worn, 

 as if the protraction of its life beyond the usual time had been attended by 

 many struggles and fightings. 



On the 4th of June, 1870, we enclosed a captured female in a pill box for 

 the purpose of obtaining eggs. The box was not examined till the 7th, when 

 several eggs Were found attached to its sides. The length of the egg was 

 3-lOOths of an inch. It was nearly globular in shape, flattened a little at the 

 place of attachment. Its color was pale yellowish green and it was covered 

 with a very fine network, the spaces between the meshes being slightly 

 depressed. 



The young larva hatched on the 19th and 20th. The box was not exam- 

 ined on the 19th, and when looked into on the 20th, several of the young 

 cieatures were too much weakened for want of food to recover. There were 

 two or three which promised well, but after the first few days only one sur- 

 vived, which has been watched over with much care and fed on grass. 



Description of the larva fresh from the egg. — Length, 52-100ths of an 

 inch. Head very large, dark brown with a few yellowish hairs. 



Body above dull whitish, with a dorsal and three lateral stripes of pale red, 

 on each segment are a number of thick, short hairs or small spines, each aris- 

 ing from a minute tubercle and tipped with a small rounded knob. Under 

 surface whitish, semi-transparent, feet and legs the same. 



No description of this insect was taken between the first and second moult- 

 ings, but after the second moult, July 20th, the following notes were taken : 



Length .35 inch. Anterior segments nearly cylindrical, posterior onisci. 

 form. Head medium size, larger than second segment, flat in front, with a 

 flattened ridge above; color pale greenish, with a black dot on each side and 

 a number of pale brown dots arranged nearly in transverse rows, and thickly 

 covered with very short whitish hairs springing from small bulb-like tubercles; 

 mandibles dark brown. 



Body above greenish grey, thickly covered with small whitish tubercles 

 similar to those on head, from each of which arises a single short brown or 

 reddish brown hair; a reddish brown dorsal stripe, and a faint sub-dorsal 

 line of the same on which is a row of dots of a similar color but of a little 

 darker shade, most distinct on middle segments; there is also a stigmatal 

 band of the same, edged below with with yellowish green, and a second fairt
