48 Psyche [April 



Middle legs purple except the same tarsal joints and the distal two- 

 thirds of the tibiae, this latter white portion with a black cinctus at 

 its middle. Caudal legs all purple, except the three proximal tarsal 

 joints and a broad white cinctus a little proximad of the middle of 

 the tibiae. i.\bdomen shining, subglabrous. Dorsal thorax scaly, 

 the scutellum more densely so; scutum with sparse pubescence. 

 Antennae wholly flat. Pedicel triangular, slightly longer than 

 funicle 6. Scape greatly dilated. Funicle joints decreasing in 

 width, increasing in length distad, 6 somewhat wider than long, 1 

 over twice so, all the joints with their distal margin concave. 

 Club conico-cylindrical, its first joint subquadrate, largest. Fore 

 wings with black, scattered stiff bristles disco-distad and from its 

 cephalic margin, with a fuscous dash across at the thickening of the 

 submarginal vein, a dusky spot against the apex of the venation 

 and an irregular dusky blotch across the apex. 



What appears to be the male is very different — winged, the 

 marginal vein somewhat longer than wide, the postmarginal just 

 developed, the stigmal very short, half the length of the marginal. 

 The wings are hyaline and fully developed. Vertex flat but shorter 

 than in the female, the frons less prominent. The antennae are 

 filiform, the club solid, the scape only compressed-cylindrical, 

 somewhat shorter than the club; pedicel globular; funicle joints 

 cylindrical, 1 longest, nearly twice longer than wide, 6 somewhat 

 longer than wide. Funicle and club with rather long, scraggly 

 hairs. The legs are concolorous except the proximal four tarsal 

 joints of the first two pairs of legs, the proximal joint of caudal 

 tarsi, the cephalic knees and tips of cephalic tibiae, middle knees 

 and tips of middle tibiae and a white central cinctus on middle 

 tibiae (therefore, two concolorous cincti; the knees include the base 

 of the tibiae and the apex of the femur). The fore femur, caudal 

 femur and tibia are compressed. The head of the male is wholly 

 concolorous.

 1908. E. G. Kelly." Types: Catalogue No. 19317, U. S. N. M.,
