 broad. 



Female. Length .6 mm. Antennae nearly as long as the body, 

 sparsely haired, 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 ; terminal segment somewhat reduced, with

Hyperdiplosis producta n. sp- 

 This species was reared by Mr. W. H. Patterson, St. \'in- 

 cent, W. I., from presumably mite galls in the inflorescence of

 thickly haired, j-ellowish ; 14 segments, the fifth having the two stems 

 with a length, respectively, twice and thrice their diameters. Distal 

 node pyriform, each enlargement with a coarse whorl of stout setae, 

 the circumfili slender ; terminal segment produced, the distal enlarge- 

 ment cylindric, with a length thrice its diameter and apically a slender, 

 fingerlike process. Palpi : first segment subquadrate, the second with 

 a length three and one-half times its diameter, the third probably as 

 long as the second, the fourth probably one-half longer, somewhat 

 dilated. Mesonotum, scutellum and postscutellum yellowish. Abdomen 

 greenish yellow. Wings hyaline, costa light straw. Halteres yellowish.

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

 fourths the length of the cylindric basal enlargement, which latter has 

 a length two and one-half times its diameter : a subbasal whorl of long, 

 stout setae and a subapical band of somewhat smaller setae; terminal 

 segment produced, with a length about thrice its diameter and apically 

 a nearly equally long, tapering process. Ovipositor short, the lobes
