 sparsely haired, fuscous yellowish; 14 segments, the fifth with a stem 

 one-third the length of the cylindric basal enlargement, which latter 

 has a length twice its diameter; circumfili moderately high, setae abun- 

 dant, stout; terminal segment with a length about two and one-half 

 times its diameter and a short, knoblike process apically. Ovipositor 

 short, the terminal lobes lanceolate, narrowly rounded and apically

Arthrocnodax meridionalis n. sp. 



This minute midge, easily separated from A. abdoiuinalis 

 Felt by the shorter sterns of the flagellate antennal segments 

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

 St. Vincent, W. I., from open Hriophyes galls on the leaves of 

 Rnellia tnbcrosa Linn, and doubtless preys upon the mites. A 

 similar, if not identical species was obtained by this gentleman 

 May 20, 191 1, from Enophyes galls on the leaves and bracts of 

 Lcpidagathis alopecuroidea. He reared the same species, April 

 6, 1911, from galls of Eriophyes gossippii on Sea Island Cot- 

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

 species of Eupatorinm. 



Larva. Length I mm., apparently yellowish, slender, the diameter 

 being only one-fifth that of the length. Head and anterior body seg- 

 ments greatly produced, the former extensile and with a length about 

 thrice its diameter. Antennae long, slender, curved, with a length about 

 half the head; mouth-parts fuscous; the body segments with a trans- 

 verse row of tubercles, each bearing a long, stout seta with a length 

 about half the body diameter; terminal segment broadly rounded and 

 with several publateral setose tubercles. Psendopods occur on the 

 third to twelfth segments. 



Male. Length .6 mm. Antennae one-fourth longer than the body, 

 thickly haired, yellowish brown; 14 segments, the fifth with stems hav- 

 ing a length respectively one and one-half and one and one-fourth 

 times their diameters ; distal enlargement subglobose, the whorls of 

 setae thick, long, the circumfili moderately stout. Palpi slender, the 

 first and second segments quadrate, with a length one-half greater than 

 the diameter, the third and fourth nearly equal, each with a length 

 twice the diameter ; mouth-parts somewhat produced, with a length 

 one-half that of the head. Mesonotum reddish brown. Scutellum, 

 postscutellum and abdomen probably yellowish. Wings hyaline, costa
