28G Mr. E. E. Austen on new 



of axillary cell ; usual scries of oblique marks across poste- 

 rior cells partly broken up into spots ; markings in basal 

 cells of normal type ; a large light blotch on sixth longitu- 

 dinal vein, beyond zigzag mark ; light loop in basal angle of 

 axillary cell large and well-marked, but not connected with 

 zigzag mark, which, in case of tyi)e, becomes indistinct before 

 reaching hind margin; discal cell Avith two transverse light 

 marks (the distal one interrupted) across median third, a 

 minute light fleck in proximal angle, and a large and con- 

 spicuous transversely elongate light mark close to distal 

 extremity ; stigma well-marked and conspicuous, dark 

 mummy-brown, an ill-defined cream-buff blotch next costa 

 at its proximal extremity, and. in case of type, an elongate 

 curved light mark (upper portion of distal rosette) imme- 

 diately beyond its distal end ; dark sepia-coloured quadrate 

 blotch below stigma extending to third longitudinal vein 

 without contracting in width, and conspicuous when wing is 

 viewed against a dark background. Halteres : knob sepia- 

 coloured_, stalk-cream- buff. Legs : front tibise slightly in- 

 crassate; basal half or rather more of first joint of middle 

 tarsi, like bands on middle tibise, cream-butf ; hind tarsi of 

 type missing.

Hcematopota tacit iirna resembles H. mactans, Austen, to a 

 certain extent in the abdominal markings, as also in the 

 apical sinuous mark in the wing being bifurcate, although, 

 in the case of the type of H. taciturna at any rate, the distal 

 ramus is not so close to the tip of the wing : the new species 

 can be distinguished from H. mactans by its darker wings, 

 in which, especially in the basal half, the light markings are 

 less extensive, by its much deeper and darker frontal callus, 

 darker antennte, and much narrower and less conspicuous 

 pale bands at the base of the front and hind tibite. 



Hcematopota hirsutitarsus , sp. n. 



$ . — Length (1 specimen) 9 mm. ; width of head 3 mm. ; 

 width of front at vertex 1 mm. ; length of wing 8"6 mm. 



Dorsum of thorax dark sepia, ivith usual grey markings ; 

 dor.wm of abdomen dark mununy-broivn on second and third 

 segments, elsewhere dark sepia, hind margins of second and 

 following segments yellmvish grey, sixth segment ivith pair of 

 small yelloivish grey adrnedian spots on basal half, in typical 

 specimen faint indications of similar spots on three preceding 

 segments ; wings sepia, fairly dark, light markings sharply
