African Phlehotomic Diptera. 409 



somewhat triangular and rather paler brown blotch, extends 

 (l(;\vnwar(ls from tip of marginal cell, its apex reaching 

 lower branch of third vein ; a third, basad, dark brown 

 blotch extends from second longitudinal vein in middle of 

 first basal cell to anal angle, widening out below; in tip of 

 wing a sinuous light mark, broadest above, runs from end 

 of second vein to distal extremity of second posterior cell ; 

 beyond this, in extreme tip of second submarginal cell, is a 

 second light mark, sometimes connected with former above, 

 in other cases fused with it to form a large light mark close 

 to tip of wing ; markings forming rosettes on each side of 

 blotch below stigma usually more or less coalescent above, 

 where they reach costa, so that there is a light area of some 

 extent at each end of stigma ; a large light area in distal 

 extremity of first posterior cell, in connexion with rosette 

 round fork of third vein; a series of narrow disconnected 

 curved marks running across middle of second and following 

 posterior cells, and a series of pale blotches on hind margin, one 

 in distal angle of each posterior cell except fourth; proximal 

 extremity of discal cell, distal extremities of both basal cells 

 (partly) and of anal and axillary cells, as well as a narrow 

 sinuous mark running from hind margin of axillary cell to 

 fifth vein, a curved mark in anal angle with concave side 

 basad, a mark across second basal cell near its base, and 

 usually another in first basal cell nearer its middle, pale ; 

 extreme bases of both basal cells generally with pale 

 markings ; alula uniformly dark brown. Halteres dark 

 brown, stalk buff. Le//5 : middle and hind femora partly 

 ochraccous buff, greyish pollinose ; greyish-white hair 

 mingling with upper part of fringe on outer side of hind 

 tibiae. 



Northern Nigeria : type and one other specimen from 

 Zungeru, June-July 1905 {Dr. Da/ziel, per Dr. J. H. 

 Ashworth) ; three specimens from Zungeru, July 1907, 

 INIarca, 4. vii. 1907, and Katscua Allah, August 1907, 

 respectively (/. Brand). 



While presenting a certain superficial resemblance in 

 fades to Hannatopota decora, Walk. (syn. H. dorsalis, Lw.), 

 11. bullatifrons is not closely allied to any of its African 

 congeners known to me, from which, apart from other 

 characters, it can at once be distinguished by its swollen and 

 Iriuged hind tibiie.
