 scape, pedicle, and the legs, except the coxae, rufous ; wings clear 

 hyaline, the nervures pale testaceous ; the head, thorax and legs covered 

 with white pubescence ; the abdominal segments fringed with white 

 pubescence. Metanotum with four areas wider than long, the apical

 a keel. Head and thorax finely minutely punctured ; the head in front 

 below the eyes finely closely longitudinally striated, the striae more or 

 less curved. Mandibles rufous, the teeth black. 9 . Length 3 mm. 



The flagellum of antennae dark fuscous. Basal three joints of an-
