light straw. Halteres yellowish. Legs a variable yellowish straw, the 

 pulvilli as long as the slender claws. Genitalia : basal clasp segment 

 long, stout ; terminal clasp segment slender, swollen ; dorsal plate 

 broadly and triangularly emarginate, the ventral plate long, rather 

 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 

 a length one-half greater than its diameter, broadly rounded apically. 

 Ovipositor as long as the body, stout, the lobes narrowly oval and 

 sparsely setose. Type Cecicl. 3.2235. 



Hyperdiplosis producta n. sp- 



This species was reared by Mr. W. H. Patterson, St. Vin- 

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

 Stachytarpha jamaicensis. It is provisionally referred to this 

 genus. 



Male. Length .75 mm. Antennae one-fourth longer than the body, 

 thickly haired, yellowish; 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. 

 Legs pale straw ; claws stout, strongly bent, swollen subapically, pul- 

 villi rudimentary. Genitalia : basal clasp segment long, the slender 

 terminal clasp segment slender, other structures indistinct. 



Female. Length I mm. Antennae a little longer than the body, 

 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 

 lanceolate and setose apically. Other characters nearly as in the male. 



Type Cecid. 32236.
