yellow, third joint usuall}'^ infuscated apically, a little more than 

 half as long as second; palpi yellow, with dense short black hair; 

 outer vertical small ; one reclinate frontal above, two to four pro- 

 clinate orbitals; lower frontals broadly diverging, extending as low 

 as base of second antennal joint; upper frontals small and sparse; 

 facial ridges flat, with two or three small bristles next to vibrissae, 

 extending almost laterally; cheek about equal to eye height; the 

 space inclosed by the suture approaches a circle in form, and the 

 parafacial is equal in width to about one-third of its diameter. 

 Back of head with dense deep golden ruff. Thorax black, subshining, 

 pollinose only a little on front edge, humeri and adjacent parts deep 

 reddish in ground color; calypters golden, the hind one bare. Scu- 

 tellum with about five pairs of bristles on margin, the middle pair 

 smaller and variable; sternopleural 2, 1. Abdomen dark reddish 

 brown to almost black, shining; second and third segments with a 

 little very thin pollen on sides at base, fourth with large lateral basal 

 spots of silvery pollen, not very dense. First segment without mar- 

 ginals, second with a widely spaced upright spiny pair, third with 

 marginal row of a dozen or more, fourth from the middle with nu- 

 merous spiny bristles ; sternites as described. Genital segments small, 

 brownish red. 



Legs black, shining, rather stout, the tarsi quite short, pulvilli yel- 

 low, conspicuous but not remarkably long ; middle tibia with several 

 bristles on outer front side, hind ones a little bowed, with dense cilia 

 irregularly arranged on hind side. 



Wings strikingly marked, yellow to the small cross vein, the re- 

 mainder dark brown along the costa, fading to a slight infuscation 

 behind, the brown however continuing along the veins; fourth vein 

 rectangular at bend, then concave, ending far before tip of wing; 

 third vein with a few hairs at base. 



Female. — Front 0.28 of head width at vertex ; third antennal joint 

 less than half the second ; abdomen wholly shining ; pulvilli a little 

 smaller. 



Length, male, 16; female, 17.5 mm. 



Described from seven males and two females; the males were re- 

 ceived through J. R. Malloch from the Federated Malay States 

 Museum, and were collected by H. M. Pendlebury at Selangor, Bukit 

 Kutu, Federated Malay States, altitude 3,500 feet. The females Vere 

 received from the Vienna Natural History Museum, and are labeled 

 " Rio Demerara, Heyne." They are old specimens ; I had described 

 the species from them as South American, when Mr. Malloch saw 

 them and told me he had received the same species from the Orient. 

 On bringing the two lots together it was apparent that the locality 

 label on the females must be erroneous.
