^16 THE CANADIAN ENTOMOLOGIST. 



In the female these two segments are more rudimentary or larva-like, 

 the mesosternum being simply transverse without intercoxal development, 

 the cox?e at extreme lateral margin, parapleura obscure. The meta- 

 sternum is shorter and broader than in the male, in dried specimens with 

 the inflexed hind margin emarginate between the widely separated coxae, 

 the episterna moderately wide and scarcely narrower behind. 



Scutellum small, triangular in the male; in the female the mesonotum 

 is short and distinctly narrower than the other segments ; the metanotum 

 again longer, although shorter than the pronotum, and somewhat wider 

 than the mesonotum. 



Elytra of male without e})ipleura. 



Coxae conical and prominent, loosely articulated and mobile, the 

 anterior pair contiguous in the male, the middle and hind pair well 

 separated, the latter a little more widely. In the female, while the body 

 is broader, the cox^ are much smaller, and reaching the same lateral 

 limits become more widely separated. 



Middle and hind legs in the male two-thirds as long as the body, the 

 anterior ones shorter ; trochanters slender, longer than wide, the femora 

 attached distally ; tibiae a little longer than the femora and without spurs ; 

 tarsi slender, a little shorter than the tibire, five-jointed, first joint as long 

 as the next two, second, third and fourth gradually shorter, fifth elongate, 

 with small simple claws. In the female the legs are very small and weak, 

 not longer than the width of the body. 



Abdomen with seven free subequal dorsal and ventral segments in the 

 male and eight in the female. 



The eggs are elliptical, twice as long as wide, translucent, shining, 

 slightly iridescent and minutely longitudinally striate. Length, 5 mm. 



The larva is somewhat contractile, elliptical, twice as long as wide, 

 obtusely rounded at each extremity, abdomen a little wider, the dorsal 

 segments corneous, shining, brown, densely fringed with spinose bristles 

 and fine hairs ; beneath with soft membraneous integuments, and finely 

 sparsely hairy. 



Head small, less than half the width of the prothoracic segment, 

 reddish-brown, rather thickly clothed with short coarse hairs, prostrate in 

 front, sparser on the vertex, and more erect behind, and with a few spinose 

 bristles. Epibtoma very short and transverse, the separation from the
