284 Mr. E. E. Austen on new 



marginal angles of posterior cells (sometimes wanting in first 

 and fourth posterior cells), a larger or smaller light blotch 

 also occiij)ying distal angle of axillary cell and sometimes 

 extending into distal angle of anal and proximal marginal 

 angle of fifth posterior cell ; basal cells with markings of 

 normal type; anal cell with zigzag mark and basal loop 

 conspicuous and with a more or less distinct connection 

 running along anal angle ; a light spot, sometimes divided 

 into two, on sixth longitudinal vein beyond zigzag mark; 

 discal cell in middle third with two transverse light marks, 

 each usually divided into two spots, also with larger or 

 smaller light spot in j)roximal angle, and sometimes with 

 similar spot or transverr^e mark near distal extremity ; stiyma 

 well marked, dark mummy-brown, its proximal extremity 

 cream- buff ; marginal cell with small light loop enclosing- 

 dark centre immediately beyond distal extremity of stigma. 

 Halteres : knob creani-bnff, slightly brownish at base above 

 and below, stalk cream-coloured. Legs : front tibial in- 

 crassate, hind tibiae not swollen : proximal two-thirds of 

 first joint of middle and hind tarsi cream-buff. 



Nyasalaiid Protectorate : tw^o sj)ecimens (co-types) from 

 the Zomba Plateau [Sir Alfred Sliarpe, K.C.M.G., C.B.) ; 

 a third specimen from Kasungu Mt., Nyika, 4. iii. 18UG 

 {Captain Richard Crawshaij) ; a fourth example of this 

 species (which I have been enabled to examine by the 

 courtesy of Lt. -Colonel Manders, ll.x\.M.O.) from the 

 Aufiri iiiver, Nyasaland Protectorate, 10. xii. 1907 {Captain 

 Hallam Hardy , R.A.M .C.) , is in the collection of the lioyal 

 Army Medical Corps College, Millbank, S.W. 



In the markings of its wings, especially as regards the 

 shape and direction of the apical sinuous mark, Hcematopota 

 insatiubilis closely resembles H. diviaapex, Austen, the co- 

 types of which are from the Katanga District of the Congo 

 Free State ; the new species, however, may be distinguished 

 from the latter by the dark and much more swollen first 

 joint of the antennae, and by its hind tibice having two pale 

 bands, instead of only a single pale baud at the base. 



Hcematopota taciturna, sp. n.
