HUNTERS OF LARGE ORTHOPTERA 197 



The prey from our two nests survived their sting and 

 imprisonment equally well. The next day, in one cell, one 

 had rotted, one had died and four responded to stimula- 

 tion; in the other cell, one had rotted, one responded to 

 stimulation, and four were motionless, but apparently living. 

 Four days later, all were dead. 



These C. ichneumoneicm also are annoyed by various 

 pests. The ever-present Melittobia were found in their 

 pupal cases kept at .home, although in nature, when the un- 

 derground nest is closed, it is improbable that they can 

 reach them. A hopper taken from one of their nests had 

 a larva attached to it that was probably a Hymenopterous 

 parasite. Our attempt to bring it to maturity failed. 



We have noticed these wasps feeding on flowers, both 

 goldenrod and sweet clover. Robertson records them as 

 feeding upon the flowers of various species of Solidago, and 

 Cockerell finds that, in New Mexico, they frequent the 

 flowers of Cleome sernilata. Folsom in his Entomology 

 figures an insect of this species with pollenia of milkweed 

 attached to its legs. Fernald 13 finds that they visit the 

 flowers of sumach, clematis, asclepias, mint, etc., and says 

 that the species has probably the widest distribution of any 

 of the Chlorioninae in America. He has seen specimens 

 from various states in the United States, and gives refer- 

 ences of their occurrence in Brazil, Guatemala, Nicaragua, 

 Costa Rica, Panama, Guiana, Venezuela, Cuba, Jamaica and 

 Santo Domingo. Howard 14 says that this species is grad- 

 ually extending its northward range. 



Pierce finds this insect to be the host of the twisted-wing 

 parasite, Strepsiptera. * Adams says that the larva of this 

 species is probably devoured by the parasitic fly, Metopia.
