[June, 



with the tibia, and a large scale-like appendage attached to the outer sur- 

 face of the globular base. This scale-like appendage is concave on its 

 inner and convex on its outer surface and overlaps the second joint. The 

 globular base is beset with prominent hairs radiating out in all directions; 

 the hairs on the scale-like appendage are shorter and stouter. The sec- 

 ond joint, which articulates with the globular base of the first joint, is 

 large and cylindrical and sends out from its proximal end a long poste- 

 riorly directed club-shaped appendage, clothed with a pencil of long hairs. 

 The h^rs on the shorter limb of the joint are smaller and more or less 

 recurved on the anterior face. The third joint is enormously enlarged 

 transversely to form a boat-shaped structure. Its hairs are limited to 

 certain portions of its surface. The fourth and fifth joints are compara- 

 tively small, the former being perceptibly swollen, the latter resembling 



the corresponding joint 

 of the fore and hind tarsi. 

 Hind legs plain, except 

 for the fringe of long hairs 

 on the tibiae, especially on 

 their posterior surfaces. 

 Wings rather long and 

 narrow, grayish hyaline, 

 with brown veins ; costa 

 near its middle with a 

 prominent black thicken- 

 ing, just beneath which is 

 a long and narrow brown 

 stigma; second vein with 

 a small thickening just 

 before its junction with 

 the third vein; discal cell 

 of medium size; halteres 

 fuscous, capitulum some- 

 what darker. Length of

wings 4 mm. 



Female (Fig. 2). — Face somewhat broader than that of the male. 

 Thorax with a thicker layer of gray dust and shorter bristles. Legs plain, 

 with much shorter hairs. Wings with somewhat paler veins and with the 

 discal cell greatly enlarged, so that the gently sinuous cross-vein which 

 forms its outer boundary lies near the posterior margin. This cross-vein 

 does not send out a vein to the margin as in the male. Length of body 

 3.5 mm.; length of wings 3.75 mm. 



This species was described from ten male and six female speci- 

 mens kindly loaned me by Mr. A. W. Snow. They were col- 

 lected at Palo Alto, Cal., March 30, 1895. 



The species is an unusually striking one on account of the re-
