Female. Length 11 mm. Head and thorax principally black; abdomen 

 principally pale rufous or ferruginous; legs black, varied with reddish; wings 

 fulvous- Head black, antennae fuscous, the basal flagellar joints but little

 median areola large, to judge from the side view nearly quadrate; basal and 

 middle lateral areas not separated. Abdomen reddish brown, the petiole 

 very dark and the other segments stained more or less above. Abdomen 

 considerably swollen toward the tip. Legs reddish, the femora of the four 

 posterior legs and the apical part of their tibiae, especially those of the middle 

 legs, black or piceous. Wings fulvous, the stigma and veins nearly concolorous ; 

 areolet large, obliquely pentangular, the upper side being short. Marginal
