segment ; terminal segment produced, the basal portion of the stem with 

 a length five times its diameter, the distal enlargement produced, swollen 

 at the distal third and with a length about 2^^ times its diameter, the 

 apex irregularly obtuse. Palpi : First segment subquadrate, the second 

 subrectangular, with a length over twice its diameter, the third narrowly 

 oval, a little shorter than the second, the fourth ^ longer than the third, 

 slender. Mesonotum dark reddish, the submedian lines yellowish-red. 

 Scutellum yellowish-red, slightly fuscous apicaliy ; postscutellum yellowish- 

 red. Abdomen reddish, the distal margins of the segments slightly fuscous, 

 especially the apical segment. Wings hyaline, costa light brown, sub- 

 costa joining costa at the basal third, the third vein uniting with the margin 

 at the apex of the wing, the fifth at the distal fifth, its branch at the basal 

 half. Halteres yellowish basally, fuscous apicaliy. Cox^e, femora and 

 tibiae mostly a light fuscous-yellowish, the tarsi darker, the apical segments 

 nearly black ; claws long, very strongly curved, the anterior unidentate, 

 the pulvilli about half the length of the claws. Genitalia : Basal clasp 

 segment moderately long, stout, obliquely truncate, the lateral angles 

 produced as rudimentary setose lobes ; terminal clasp segment stout, with 

 a length hardly twice its diameter, excavated and broadly rounded 

 apicaliy, setose ; dorsal plate moderately long, deeply and triangularly 

 incised, the triangular lobes tapering to a sparsely setose apex ; ventral 

 plate long, deeply and roundly emarginate, the lobes narrowly rounded 

 apicaliy and sparsely setose ; style stout, very strongly curved, narrowly 

 rounded apicaliy. 



Female. — Length, 1.2 mm. Antennae nearly as long as the body, 

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

 about ^ the length of the subcylindric basal enlargement, which latter 

 has a length twice its diameter; subbasal whorl moderately thick, sub- 

 apical band thick, the setae strongly curved ; terminal segment subcylindric, 

 with a length over twice its diameter and apicaliy with a short, knob-like 

 appendage. Mesonotum dark red, the submedian lines yellowish-red. 

 Scutellum reddish, slightly fuscous apicaliy ; postscutellum reddish. 

 Abdomen sparsely setose, deep red, the dorsal sclerites and the posterior 

 Yl of the segments dark red; venter bright red. Ovipositor short, the 

 terminal lobes narrowly lanceolate, with a length about twice the width 

 and rather thickly setose. Other characters about as in the male.
