 blackish eyes. (Comstock) 



Male. Length 1.5 mm. Antennae nearly as long as the body, 

 rather thickly haired ; 14-16 antennal segments, the fifth with a 

 stem as long as the basal enlargement, which latter has a length 

 one-half greater than its diameter ; terminal segment reduced, some- 

 times broadly fused with the preceding. Palpi ; first segment sub- 

 quadrate, the second a little longer, stout, the third one-half longer 

 than the second, slender, the fourth a little longer than the third. 

 Mesonotum reddish brown, the submedian lines sparsely haired. 

 Scutellum yellowish orange, postscutellum a little darker. Abdo- 

 men reddish orange; genitalia reddish brown. Wings (pi. 6, fig. i) 

 hyaline, costa dark brown, subcosta uniting therewith at the basal 

 third. Halteres yellowish. Coxae and femora basally yellowish, 

 distal portion of femora, tibiae and tarsi dark brown ; claws stout, 

 strongly curved, the pulvilli longer than the claws. Genitalia ; basal 

 clasp segment stout ; terminal clasp segment long, stout ; dorsal plate 

 short, broad, deeply and triangularly emarginate, the divergent lobes 

 broadly rounded ; ventral plate deeply and roundly emarginate, the 

 lobes narrow. Harpes long, narrow, irregular; style long, slender. 



Female. Length 1.5 mm. Antennae extending to the third ab- 

 dominal segment, sparsely haired, dark brown; 14 or 15 cylindric 

 segments, the fifth with a length twice its diameter ; subbasal whorl 

 sparse, subapical band scattering; terminal segment reduced or 

 fused with the preceding. Palpi ; first segment short, stout, second 

 broadly oval, the third a little longer, more slender, the fourth 

 longer and more slender than the third. Ovipositor relatively stout 

 and not longer than the body, the terminal lobes with a length four
