with sparse hair. vSciitellum^ of the usual great width, black, with 

 close very short black hair, and some pale hairs on the margin. 



Abdomen tawny, posterior borders of segments with a black 

 band, wider in some specimens than in others, and with a tendency 

 sometimes on the 2nd segment to form a dorsal band. Centre of 

 ist segment black. At each of the fore corners of the 3rd and 4th 

 segments is a triangular brassy metallic spot (not strikingl^^ con- 

 spicuous, as the colour is so similar to the ground colour) which 

 is somewhat raised, and does not attain the ridged sides of these 

 segments. Whole dorsum covered with short yellow hair, which is 

 darker on the posterior part of each segment ; a minute row of 

 black hairs on the extreme edge of each segment. Belly tawny with 

 some yellow hair, centres and posterior halves of the segments more 

 or less blackish.

Legs : coxte blackish grey, hind pair with a little yellow hair ; 

 femora wholh' brown, sometimes lighter, sometimes nearly l)lack, 

 but ah^ays uiiicoloroiis, except that the extreme tip is occasionally 

 lighter, with light golden yellow hair ; tibi?e, rather variable, 

 usually with tawny basal half and lighter or darker brown apical 

 half, with yellowish or whitish hair, which is brown or black on 

 the darker parts ; tarsi dark brown, with yellowish grey hair below, 

 which is sometimes golden brown under hind pair. 



Winces nearly clear, a little tawny brown suffusion at base, 

 in the mediastinal cell, and near the l^ase of the discal cell. Hal- 

 teres yellow. 



Described from four cf cf and four 2 9 in fair condition (sup- 

 plemented by a long series of both sexes in indifferent condition) 

 in the Indian ]\Iuseuni collection from Bangalore and Calcutta. 

 Allied to errans, F., but quite distinct. The sub-metallic raised 

 triangles on the abdominal 3rd and 4th segments are identical with 

 those in errans, F., but the hind femora are never pale on the basal 

 half and dark on the apical. This character alone, or the thoracic 

 markings, will at once separate the two species.
