 yellow legs and otherwise different in the relative length of the antennal 

 joints. 



In the family Bracouidiie the little cotton-aphis parasite Lysiphlebus 

 testaceipes Cr. was quite plentiful and fairly cleaned the leaves of this 

 troublesome plant-louse. It was reared several times during July and 

 August, and between this parasite, the larvte of syrphid flies, golden- 

 eye flies, and the Coccinellidae, the aphis was having a terrible struggle 

 for existence. Besides the above species three other bracouids were 

 captured on cotton which are evidently associated with some injurious 

 insects found thereon, viz., Iphiaulajc triangularis Ashm., Chelorms 

 teranus Cr., and Microdus sanctus Say.
