Itonida cucurbitae n. sp. Male. — Length 1 mm. Antennae with fourteen segments, 

 the fifth having the basal portion of the stem with a length twice its diameter, the 

 distal part with a length three times its diameter; basal enlargement subglobose, 

 the subbasal whorl rather tliick, subapical ciroumfihim with loops extending to 

 the base of the produced distal enlargement, which latter has a length one half 

 greater than its diameter, a rather thick whorl of stout seta; and subbasal and sub- 

 apical circumfili, the loops of the latter extending to the apex of the segment. Palpi 

 probably quadriarticulate. Mesonotum yellowish brown, the submedian lines, 

 scutellum and postscutellum fuscous yellowish. Abdomen yellowish brown, rather 

 thickly clothed with yellowish hairs. Wings hyaline, costa light straw, the third 

 vein uniting with the margin well beyond the apex. Haltercs whitish transparent. 

 Legs a light yellowish brown, the distal tarsal segments darker; claws rather long, 

 stout, strongly curved, the puIviUi shorter than the claws. Genitalia; basal clasp 

 segment short, strongly curved, truncate; terminal clasp segment long, slightly 

 swollen basally; dorsal plate rather long, deeply and triangularly emarginate, the 

 lobes broadly rounded; ventral plate rather long, broadly rounded; both plates 

 sparsely setose. Harpes rather long, tapering, obtuse; style short, tapering to a 

 subacute apex. 



Female.— Length 1 mm. Antennae hght brown; fourteen segments, the fifth 

 with the stem one fourth the length of the cylindric basal enlargement, which latter 

 has a length about four times its diameter, is shghtly constricted near the middle; 

 subapical band scattering, the seta; strongly curved; terminal segment produced, 

 the basal enlargement with a length five times its diameter; apically there is a 

 long, finger-hke appendage, the latter swollen basally. Palpi; first segment sub- 

 quadrate, the second with a length three times its diameter, the third as long as 

 the second, more slender, the fourth longer than the third. Ovipositor short, the 

 terminal lobes narrowly oval and sparsely setose. Other characters practically as 

 in the opposite sex. 



Reared from orange larvae from a squash having a curious rough, 

 fulvous appearance. Loaned for study by U. S. Bureau of Entomology. 

 Mycodiplosis cucurbitae Felt was associated with this form. Type 

 C. 966. 



Itonida spiraeina n. sp. Male. — Length 1.5 mm. Antennae dark brown, j^ellov\-ish 

 basally; fourteen segments, the fifth binodose, the basal portion of the stem with 

 a length thrice its diameter, the distal part with a length four and one half times 

 its diameter; the basal enlargement subglobose, the distal subcylindric, with a length 

 one half greater than its diameter, the whorls of .setie long and stout; circmnfili with 

 the loops long, stout and rather sparse; terminal segment produced, the distal 

 enlargement with a length three times its diameter and with a long, tapering apical 

 process. Palpi fuscous yellowish; first segment irregular, fusiform, the second one 

 half longer than the first, the third a little longer than the second, the fourth about 

 as long as the third; face and mesonotum fuscous yellow^sh, the submedian lines 

 yellowish, sparsely haired. Scutellum fuscous yellowish, setose apically; post- 

 scutellum yellowish white. Abdomen sparsely haired, fuscous yellowish, the insis-
