(fig. 2) is reddish, with black hairs on the hark of each segment. The 

 abdomen of the male (fig. 3) terminates with a pair of clasping organs, 

 while that of the female is provided with a long, pointed, extensile 

 ovipositor, about twice as long as the remainder of the body. 



The egg is only about one one-hundredth of an inch long, oval, about 

 three times as long as broad, pale yellow when first deposited, but 

 becoming tinted with orange as it nears hatching. 



The larva (fig. 4) when 

 full grown is about one- 

 twentieth of an inch long, 

 footless, ranging in color 

 from nearly white to orange- 

 red, according to age. 



The pupa is pale orange 

 in color, with brown eyes. 

 On the front of the head are 

 two short, conical tubercles, 

 and behind them two long 

 bristles. The sheaths inclos- 

 ing the antenna' are curved 

 outward like the handles of 

 an urn. 



LIFE HISTORY. 



The pupa is inclosed in 

 a compressed, tough, oval 

 silken cocoon, and when the 

 fly is ready to emerge the 

 pupa pushes itself out of 

 this cocoon to the surface 

 of the ground. 



It is within the cocoon 

 that the winter is passed, 

 and the time in spring when 

 it conies forth as an adult 

 varies with the hit itude and 

 season, probably closely corresponding to the heading of red clover. 



After pairing, the female proceeds to deposit her eggs in the clover 

 head, pushing them beneath the bracts or enveloping leaves, or down 

 between, but not fastening them in any way to the seed capsule, and in 

 no case, so far as observed, within the florets. Although deposited 

 singly, Professor Comstock reports as many as 50 eggs in a single head. 

 In hatching, the larva must make its own way into the open end of 

 the floret, which offers only sufficient quarters for one individual. In 

 this floret it feeds, and from it, when full grown, it makes its exit and
