brown with the bases and tips paler; metatarsi obscure yellow, the 

 terminal tarsal segments dark brown; the posterior legs are longer 

 than the others, the femora somewhat swollen, the tibiae more or less 

 curved and only the terminal two tarsal segments infuscated. Wings 

 with a strong yellowish tinge, brightest in cells C, Sc and £nd A; b, 

 conspicuous brown pattern distributed as follows: a brown area in the 

 base of cell R; a large, quadrate area at origin of Rs that barely reaches 

 M; the broad stigmal area extends as a solid block to cell 1st Mo where 

 it splits, the center of the cell being of the ground-color; wing-tip 

 broadly pale brown, including the apices of cells R2, Rr„ R5, Mi and 

 2nd M2; a conspicuous brown cloud in cells Cu and 1st A at the end of 

 vein 2nd A ; veins dark brown, more fiavous in the yellow areas; micro- 

 trichiae abundant in all cells beyond cord; in the radial cell they are 

 practically lacking outside of the darkened areas. Venation: Sci ending 

 just before the tip of Rs, Sd faint, at the tip of Sci\ Rs long, feebly 

 angulated at origin; cell Ri sessile, the petiole entirely lacking; r close 

 to tip of Ru r-m very short, the deflections of i?4+5 and Mm 2 being cor- 

 respondingly longer; petiole of cell M] a little shorter than the cell; 

 basal deflection of Cui at midlength of cell 1st M^. 



Abdominal tergites shiny obscure yellow; segments six to eight 

 metallic purple; lateral margins of tergites narrowly blackened; ninth 

 segment and ovipositor orange; basal sternites obscure yellow; sub- 

 terminal segments dark. Ovipositor with the valves very long and 

 slender, straight.

 altitude 2018 ft., February, 1920. {T. Harris). 



Gynoplistia harrisi is a very distinct species of the genus. It 

 is dedicated to the collector. Mr. Thomas R. Harris. 



Gynoplistia unimaculata, sp. n. 



Allied to G. ciiprea Hutton; a conspicuous, slender tubercle 

 on lateral sclerite of mesonotal postnotum; wings yellow, 

 unmarked except for the dark brown stigma; abdomen with 

 the basal tergite purple, segments two to six orange-yellow. 

 Sex? — Wing 12 mm. Head destroyed by insect pests. 



Mesonotum shiny reddish brown. Pleura reddish brown, the 

 mesepistemum and dorsal parts of the mesosternum with a golden- 

 yellow pollen; ventral portions of the mesosternum with metallic pur- 

 ple reflexions; lateral sclerites of postnotum immediately cephalad of 

 the base of the halteres with a conspicuous, slender tubercle, directed 

 laterad and slightly caudad. Halteres yellowish ochreous. Legs with 

 the coxae and trochanters reddish brown; femora light orange; tibiae 

 dark brown, the extreme base paler; tarsi dark brown. Wings with a 

 strong brownish yellow tinge, clearer yellow in the costal region and 

 the cells basad of the origin of Rs ; no markings on the wing except the 

 conspicuous, dark brown stigma; veins dark brown, more yellowish in
