130 STUDY OF 



Division, — First. 

 Genus,— Tenthredo. 

 Species, — Tenthredo.* 



Superior wings, with but one marginal cell : 

 head, antennae, thorax and wings, brown and 

 shining : body yellow and shorter than the 

 wings : the female larger than the male, and 

 the body of a brighter yellow ; the antennae with 

 seven articulations, decreasing in size towards the 

 apex; and, as well as the body and wings, 

 slightly ciliated. 



Following the classification of Bergman, the 

 larvae may be thus described. 



Head, — horny, with projecting teeth. 



Feet, — six proper horny, twelve ventral, and 

 two caudal membranaceous; metamorphose into 

 nymphae, which give birth to tenthredines. 



I apprehend, it will be found, that, in warm 

 weather, the larvae are generally hatched on the 

 third day after the eggs are deposited. They 

 feed together for the first day, but by the time 

 they have consumed the leaf on which they were 

 born, they will have attained a sufficient size to 

 detach themselves singly on the work of destruc-
