 1 female. 



Type, Cat. No. 30188, U. S. Nat. Mus. 



Closely related to the European Tanypeza longimana Fallen, 

 of which a pair are before us collected by Dr. M. Bezzi in 

 Sondrio, Italy. This latter species is slightly less in stature 

 and more slender, the hairs of the mesonotum are finer, more 

 sparse, and black. The hairs of the abdomen are black 

 throughout. The front femora are heavily marked with 

 piceous brown, this color spreading out to a broad diffused 

 ring on the distal half. The wings are clear and are dis- 

 tinctly shorter and broader than in the American species.

 margins. Genovertical plates silvery pubescent, produced and 

 broadened to a short distance above antennse, where they al-

 pairs of stout fronto-orbital bristles, the pair of ocellar bristles

 the other pair of verticals. Antennse with the first two joints

 short black marginal hairs ; cheeks narrow, with a silvery 

 white beard. Proboscis yellow ; palpi black. Mesonotum 

 shining black, the humeri with silvery pubescence, the disk
