 sparsely haired, light brown; 16 segments, the fifth with a stem 

 one-third the length of the basal enlargement, which latter has a 

 length two and one-half times its diameter ; terminal segment reduced, 

 narrowly oval. Palpi; first segment produced, swollen distally, 

 second roundly rectangular, the third more than twice the length 

 of the second, slender, the fourth nearly as long as the third, slender. 

 Mesonotum yellowish brown, the submedian lines sparsely haired. 

 Scutellum and postscutellum reddish brown. Abdomen sparsely

 a little darker; claws long, evenly curved, the pulvilli as long as 

 the claws. Genitalia; basal clasp segment stout; terminal clasp 

 segment short, swollen; dorsal plate broad, triangularly emarginate;

Female. Length 2.5 mm. Antennae extending to the second 

 abdominal segment, sparsely haired, pale ^^ellowish; 16 segments, 

 the fifth with a stem one-fourth the length of the basal enlargement, 

 which latter has a length nearly three times its diameter; terminal
