African Phlebotomic Diptera. Ill 



with hind borders of segments drab-grey or greyish cream- 

 buff, second to sixth segments inclusive each with an ill-defined 

 smoke-grey median stripe, sometimes indistinct or obsolete on 

 segments after the second; wings light sepia- coloured, pale 

 markings similar in pattern to those in wings of foregoing 

 species but less coarse, and loop and zigzag mark in axillary 

 cell not connected; legs as in foregoing species. 



Head : front drab- grey , vertical region with a more or 

 less distinct sub-triangular brown mark on each side of 

 median line, which is occupied by a narrow grey stripe 

 running from median frontal spot to margin of occiput; 

 face and jowls smoke-grey, area between lower inner margin 

 of eye and antenna on each side generally more or less dotted 

 with mummy-brown, or exhibiting commencement of a 

 horizontal dark brown streak, below each antenna a small 

 dark brown fleck, usually less conspicuous than in foregoing 

 species ; frontal callus mummy-brown, rather narrow from 

 above downwards, extending from eye to eye, upper margin 

 straight or nearly so, not indented in middle line; a well- 

 marked seal-brown median spot below callus ; median as 

 well as lateral clove-brown frontal spots present, latter in 

 contact with or narrowly separated from eyes ; palpi as in 

 foregoing species, except that terminal joint on outer side, 

 in addition to its covering of black hair, is clothed, chiefly 

 at base and below, with pale yellowish hair; first and second 

 joints of antenna greyish fawn-coloured, clothed with black 

 hair, first joint slightly swollen on inner side, third joint 

 hazel or mummy- brown, moderately elongate, last three 

 annuli dark brown. Abdomen : admediau grey spots on 

 dorsal surface of first six segments, sometimes so large as to 

 be confluent and appear as a pair of broad admedian longi- 

 tudinal grey stripes ; venter as in foregoing species, dark 

 median sti'ipe extending from base to tip. Wings : light 

 markings sharply defined, except indistinct pale mark in 

 second submarginal cell, beyond apical sinuous mark ; light 

 blotches on hind margin smaller than in foregoing species, 

 and usually no light blotch in fourth posterior cell ; stigma 

 and light mark before it as in previous species ; light mark- 

 ings in discal cell as in foregoing species. Halteres as in 

 foregoing species. Legs : front tibiae, in addition to pale 

 band near base, with some pale yellowish hairs in or below 

 middle, representing a rudimentary or vestigial second pale 

 band. 



Nyasaland Protectorate : twenty-four miles from Blantvre, 

 22. i. 1905, 6.0 to 7.0 a.m. (Dr. J. E. S. Old). The collector's
