Epihormomyia auripes sp. nov. 



This beautiful species was collected by Mr. H. S. Parrish, jNIarch 

 19, 1913, at Mallali, Demerara River, British Guiana, and donated 

 to the state collections by C. P. Alexander. 



Female: Length, 5 mm. Antennae extending to the sixth abdominal segment, 

 rather sparsely haired, mostly brownish yellow; 14 segments, the third to the ninth 

 distinctly binodose, the tenth and eleventh slightly so, the remainder with a sub- 

 cylindric basal enlargement, the third and fourth segments fused, the fifth having 

 the stems with a length one and one-half and two and one-half times their diameters, 

 respectively, the basal enlargement subglobose and without circumfili, the distal 

 enlargement cylindric, with a length about three and one-half times its diameter 

 and low circumfili, united by a longitudinal thread, basally and apically; near the 

 middle there is a scattering band of long, slender, curved setae; the twelfth segment 

 with a stem about one-half the length of the subcylindric basal enlargement, which 

 latter has a length fully four times its diameter, the fourteenth segment with a re- 

 duced, fusiform, apical process about one-fourth the length of the subcylindric basal 

 enlargement, which latter has a length four times its diameter and tapers distally. 

 Palpi; first segment subquadrate, the second with a length nearly three times its 

 diameter, the third one-half longer than the second, more slender. Eyes holoptic. 

 Mesonotum not greatly produced as in Hormomyia, yellowish orange. Scutellum 

 and postscutellum yellowish. Abdomen mostly dark brown, the long ovipositor 

 dark yellowish brown. Wings hyaline, narrow, with a length about three times 

 the width, subcosta uniting with the margin at the basal third, the third vein well 

 beyond the apex, the fifth at the distal third, its branch near the basal third; hal- 

 teres pale yellowish. Coxje dark brown, the legs mostly golden yellow, except the 

 basal third of the anterior and posterior femora, the basal three-fourths of the mid- 

 femora and the ventral line on the midtibife, these being dark brown; claws on the 

 two tarsi remaining and free from the basal portion of the leg, stout, strongly curved, 

 unidentate, the pulvilli about one-third the length of the claws. Ovipositor stout, 

 about half the length of the abdomen when extended, the terminal lobes sparsely 

 setose, short, broadly and irregularly rounded, minor lobes short, obliquely tri- 

 angular. 



Type: Cecid. 1599. 



Lestodiplosis picturata sp. nov. 



This midge, collected by H. S. Parrish and donated by C. P. 

 Alexander, is labeled Bartica, British Guiana, December 27, 

 1912. It is a very strongly marked form and apparently tyj^ical 

 of the genus. 



Female: Length, 1.2 mm. Antennae as long as the body, rather thickly haired, 

 mostly pale yellowish, darker basally; 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; terminal segment produced, the basal enlarge-
