Genus Anisocheleomyia. 575 



Anisocheleomyia leucoptera. n. sp. 



Head deep brown with flat dark scales with violet reflections, 

 pale at the sides ; thorax brown with a line of silvery white 

 flattish scales outstanding on each side. Abdomen brown, 

 ornamented with white scales on the first to fourth and apical 

 segments, the scales mainly apical. Legs brown unhanded. 

 Wings white scaled except for a dark brown area on the basal 

 part of the costa, and ending in a brown patch over the cross- 

 veins, where the membrane is also tinged with brown. 



$ . Head deep brown clothed with flat dark scales with deep 

 violet reflections, some paler flat scales at the sides \ antennae 

 pilose, brown ; proboscis deep brown. 



Thorax (partly denuded) brown with a line of flat outstand- 

 ing silvery white scales on each side of the mesothorax in front 

 of the wings ; the middle with narrow-curved bronzy scales ; 

 scutellum brown with traces of small flat brown scales • pleurae 

 grey and brown with patches of flat grey to pale blue scales ; 

 metanotum deep brown. 



Abdomen deep brown, the first to fourth segments with 

 white scales, mainly on the apical areas of the segments but on 

 the second extending to the base, white scales also on the apical 

 segment ; posterior border-bristles brown. 



Legs deep brown with bronzy reflections, ungues of the fore 

 and mid legs not so very unequal in length, but in breadth, the 

 fore pair curved almost at right angles, one broader than the 

 other; the mid more unequal, the largest broad and curved, 

 the smaller with two blunt teeth, one basal. 



Wings with white scales to the veins, except the basal two- 

 thirds of the costa, some on the sub-costal and first long vein 

 and the second at the region of the cross- veins and towards the 

 base of the second, just above the cross-veins where the dark 

 scales are collected the wing membrane is tinged with brown, this 

 making a well contrasted dark area on the white wing field \ the 

 first sub-marginal cell slightly smaller than the second posterior 

 cell, its stem two and a third times the length of the cell ; stem of 

 the second posterior, one and a-half times the length of the cell ; 

 supernumerary vein thick, brown, meeting the narrow mid vein, 

 the posterior much longer than the mid, arising from near the 

 base of the upper branch of the fifth ; sloping backwards and 

 about its own length distant from the mid ; the lateral vein- 

 scales are large and lanceolate, the median small and spatulate ;
