LIST OF HOMOPTEROUS INSECTS. 1105 



humeral angles and a perfect ovipositor. For the greater certainty 

 I took pains to trace its history, and have reared it from the larva, 

 which I have figured, as well as the propupa and pupa. For a long 

 time, indeed, I sought the other sex in vain, and was almost induced 

 to fancy that like Cynips, the insect might be unisexual. But re- 

 membering that at some seasons females only occur of Limothrips, 

 I did not give up the search, and guided by that indication I at last, 

 at the season of hay-harvest, discovered the male, though excessively 

 rare, I may say not a single one to several hundreds of the female. 

 Amyot has gone farther, for while he follows Burmeister in this, he 

 treats as a larva Phlceothrips pedicularia also, the development of 

 which Burmeister had recognized." — Holiday, MSS.
