species. Of these cuprina ' is a described species and the cf and 

 9 ? of it apparently are co- types ^ and therefore, presumabh% 

 correctly 'identified. Cupropicta and ffavitarsis (two $ 5 and one 2 

 respectively) are certainh^ only the same species as cuprina, and 

 are probably nomina niida. The other species, auronitens , is ap- 

 parently a good s])ecies, which I describe here, with a second very 

 distinct species from Assam. 



X. auronitens, mihi, sp. nov. 

 (Id. id. ; Bigot, nom. mid.) 

 & . Assam. Long. 12 mm. 



Head : vertex shining black, a few yellow hairs immediately 

 above junction of eyes, which are contiguous for only half the 

 distance from the frontal prominence to the crown of the head.

 eyes touch ; ocelli distinct, no ocellar prominence. PVons shining 

 black, grey dusted round the margins, v/ith lower edge immediately 

 above the antenna?, tawny. Cheeks and lower part of face 

 blackish, with a 1)rownish bhie tinge, with whitish reflections in 

 certain lights. Antenme reddish lirown, ;;rd joint lighter, whitish 

 dustt^d ; arisca reddish brown. Mouth and proboscis brown. Back 

 of head grey, encompassed l-y a fringe of gold-yellow hair, which 

 is shortest behind the upper corners of the eyes. 



Thorax : dorsum golden brassy, with gold-yellow hairs, which 

 are absent in the centre, giving an appearance, seen from behind, 

 of a dark dorsal stripe. Humeral calli, bluish black, with a few 

 3'ellow hairs. vSides of thorax blackish, shining, with some scattered 

 yellow hairs. Mesopleura, pterojileura and sternopleura, aenous

 fore tibiae bearing a fringe of long yellow hair on their inner sides. 



I This specific name has been nsed for a second time by Coquillet for a species 

 from Japan described by him in 1898 (Proc. U. vS. Nat. Mns., xxi, 327). Bigot's 

 species therefore antedates this latter by thirteen years.
