clothed with dark brown scales interspersed with numerous yel- 

 lowish ones ; subcosta and first and second longitudinal veins more 

 sparsely clothed with similar scales; fringe pearly gray. Petiole 

 of first submarginal cell about two thirds the length of the cell, that 

 of the second as long as its cell. Posterior cross vein a little over 

 its own length from the mid cross vein. 



Described from a freshly reared specimen. 



Male. Proboscis about two thirds the length of the body, dark 

 purple. Palpi dark brown, the third segment capitate and with a 

 broad basal and a median white band, a lateral whitish patch of 

 scales apically, with a rather sparse ventral tuft and with two 

 short, stout, subapical setae; this segment one third longer than 

 the combined nearly equal fourth and fifth segments, the fourth 

 with a broad, well defined, white basal band, the fifth with a rudi- 

 m.entary basal band of the same color, more slender than the fourth 

 and extending its own length beyond the proboscis. Antennae, 

 basal segment dark brown with a conspicuous internal patch of 

 white scales, densely clothed with grayish yellow plumes basally. 

 Segments 13 and 14 about half the length of the entire organ, 

 14 being three fourths the length of 13. Occiput rather sparsely 

 ornamented with silvery yellow, cur^'ed scales and rather nirmerous 

 erect white and a few black, fork scales posteriorly. The lateral 

 posterior margin of the head is clothed with a rather thick patch 

 of silven.' white scales. Mesonotum with broad, submedian, dark 

 bro^^Ti stripes becoming silver}^ yellow and obsolete posteriorly,

 anterior lateral angles more or less conspicuous brownish spots. 

 Pleura rather sparsely clothed with silvery- white scales. Scutel- 

 limi sparsely clothed with yellowish white scales and with large, 

 median and conspicuous lateral apical tufts of long, golden yellow 

 scales: postscutellum smooth, light brown. Halteres with the 

 apical portion more or less fuscous, basal whitish transparent. 

 Abdomen dark brown with distinct, rather broad basal yellowish 

 white bands slightly produced laterally, those on the fifth and 

 sixth segments covering the anterior half and that on the seventh 

 most of the segment: the eighth sparsely clothed with silvery 

 white scales. Basal clasp segment dark brown. Ventral surface 

 rather sparsely suffused with silver}^ white scales, with a some- 

 what broken median stripe of brown scales. Coxae yellowish 

 brown ; legs banded, dark brown ; the femora and tibiae well flecked 

 with yellowish white scales, their ventral surface yellowish. Tarsi 

 with well marked basal bands, those on segments i to 4 of the 

 hind legs broad, those of the fore and mid legs on segments 2 to 3, 

 narrow, bright, that of the fourth of the mid legs and the fifth of 

 the hind lesfs narrow or rudimentar\'. Claws of anterior and 

 middle legs unequal (the shorter simple), the longer claw of the 

 middle leg being nearly straight. Wings with the cost a clothed 

 with dark brown scales, first and second longitudinal veins more 

 sparsely ornamented with light brown scales mixed with yellowish 

 ones; fringe pearly gray. Petiole of first submarginal cell about the

 Posterior cross vein about its own lensrth from the mid cross vein.
