times its diameter; each enlargement subglobose, with a sparse subbasal whorl of 

 moderately stout setaj and a circumfilum, the loops of the latter rather stout and 

 extending to the succeeding enlargement; terminal segment having the basal portion 

 of the stem with a length about twice its diameter, the distal enlargement produced^ 

 fusiform, with a length about twice its diameter. Palpi; first segment stout, 

 swollen distally, second rectangular, with a length nearly three times its diameter, 

 the third one third longer than the second, more slender, the fourth one fourth longer 

 than the third, somewhat dilated. Mesonotum slaty brown. Scutellum reddish, 

 thickly setose; postscutellum reddish brown. Abdomen sparsely setose, a nearly 

 uniform yellowish red. Wings hyaline, costa yellowish brown, the third vein unit- 

 ing with the margin just beyond the apex of the wing. Halteres reddish brown^ 

 yellowish apically. Coxae slaty brown; femora, tibia? and tarsi reddish yellow, the 

 femora and tibise somewhat darker apically; claws slender, evenly curved, the 

 pulvilli as long as the claws. Genitalia; basal clasp segment moderately stout; 

 terminal clasp segment stout, moderately long; dorsal plate short, triangularly 

 emarginate, the lobes broadly rounded, setose; ventral plate deeply and triangularly 

 emarginate, the lobes slender and narrowly rounded apically; style short, tapering, 

 subacute. 



Female. — Length 1.5 mm. Antenna; dark browTi; fourteen subsessile segments, 

 the fifth having a stem about one sixth the length of the subcyhndric basal enlarge- 

 ment, which latter has a length two and one half times its diameter, and a thick 

 subapical band of short, stout setae; circumfih well developed, rather high ; terminal 

 segment cylindric, with a length nearly tliree times its diameter and taperimg to 

 a narrowly rounded apex. Palpi; nearly as in the male. Mesonotum slaty browTi, 

 the yellowish submedian lines thickly setose. Scutellum reddish brown, thickly 

 setose; postscutellum reddish brown. Abdomen sparsely setose, the dorsal sclerites 

 dark reddish brown, the venter reddish orange. Halteres yellowish brown. Coxae 

 slaty brown. Legs mostly yellowish brown, the tibiae and tarsi somewhat darker 

 apically. The slender ovipositor one half longer than the body; terminal lobes with 

 a length six times the mdth, subacute, sparsely setose.

Dicrodiplosis cocddarum n. sp. Fenmle. — Length L5 mm. Antenna; dark brown; 

 probably fourteen segments, the fifth with a stem about one fourth the length of the 

 cyhndric basal enlargement, which latter has a length about one half greater than 

 its diameter, a thick subapical band of shorter, fine setae. The circumfUi are im- 

 usual in that the basal filum bends strongly towards the apex of the segment and in 

 some instances anastomoses irregularly, the distal circumfili has rather high loops. 

 Palpi; first segment subquadrate, the second narrowly oval, the third rectangular, 

 with a length nearly three times its diameter, the fourth fusiform and about as long 

 as the third. Mesonotum dark brown, the submedian lines indistinct. Scutellum 

 reddish brown, postscutellum yellomsh. Abdomen sparsely haired, dark brown. 

 Wings hyaHne, costa pale yellowish, subcosta uniting therewith before the basal half, 

 the third vein at the apex, the fifth at the distal fourth, its branch near the basal half. 

 Legs a variable yellowish transparent, the middle claw at least stout, strongly 

 curved, unidentate, the pulvilU about half the length of the claws. Ovipositor short, 

 the terminal lobes narrowly oval, with a length about twice the width and thickly 

 setose.
