Walkers's Type (female) from Doré, New Guinea in Brit. Mus. Coll. BlGOT's type 

 from New Guinea. In his description he says "3 spécimens", but two of thèse are a wholly 

 différent species, the legs being red, the palpi yellow and the abdomen reddish. The spécimen 

 labelled as the type agrées with his description and is identical with Walker's type, and is 

 a female, not a maie as stated by Bigot. In Dr. KertÉSZ's Coll. 2 females from Keepaun 

 and Finsch Harbour, German New Guinea. 



A dark reddish brown médium sized species, the thorax lighter, covered with yellowish 

 grey tomentum, the wings tinged brown. Legs black. Length, WaLKER's type 18 m. m. 

 BlGOT's type 14 m. m. other females 18 m. m. 



Face covered with yellowish brown tomentum, some brown hairs on the cheeks. Palpi 

 reddish brown with black pubescence, stout at base ending in a point. Beard brown. Antennae 

 reddish yellow, the first two joints appearing darker, with black pubescence, the third dusky

 long as it is wide anteriorly where it is little more than half as wide as it is at vertex. 

 Frontal callus very narrow cylindrical, not much wider than its long lineal extension, blackish 

 in colour. Thorax reddish brown or blackish, but covered with the yellowish grey tomentum 

 so that it lias a pale appearance, ail the spécimens are faded and poor, in well preserved

 dorsum, hairs at sides also black. Legs blackish with black pubescence. Wings tinged brown
