Arthrocnodax meridionalis n. sp. 



This minute midge, ea.'^ily separated from A. abdominalis 

 Felt by the shorter stems of the flagellate antennal segments 

 in the male, was reared May 7, 191 1, by Mr. W. H. Patterson. 

 St. \^incent, W. I., from open Briophycs galls on the leaves of 

 Ruellia tnherosa Linn, and doubtless preys upon the mites. A 

 similar, if not identical species was obtained by this gentleman 

 May 20, TQiT. from Eriophycs galls on the leaves and bracts of 

 Lepidagathis alopccuroidea. He reared the same species. April 

 6, igii, from galls of Brwphyes gossippii on Sea Island Cot- 

 ton and also on April iSth from mite galls on the leaves of a 

 species of Eupatorium.
