yellow legs and otherwise different in the relative length of the antenna! 
joints. 
In the family Bracoukhe the little cotton-aphis parasite Lysiphlebus 
tentaceipes Cr. was quite plentiful and fairly cleaned tUe leaves of this 
troublesome plant-louse. It was reared several times during Jul}' and 
August, and between this parasite, the larvae of syrphid flies, golden- 
eye flies, and the Coccinellidffi, the aphis was having a terrible struggle 
for existence. Besides the above species three other braconids were 
captured on cotton which are evidently associated with some injurious 
insects found thereon, viz., Iphiaulax triangularis Ashm., Ghelonus 
texanus Cr., and Mierodus sanetus Say. 
The following species of Ichneumonida; are apparently new:
