The 3rd antennal segment (fig. 3, c) and the distal segment of the superior clasper 

 (fig. 3, d) of P. sergenti drawn to the same scale as the corresponding structures 

 in this var. are given for comparison and convenience of reference. 



Mesopotamia: Amara, 1 cJ, taken at light, 19.ix.l8 {Capt. P. A. Buxton); 

 another ^ from the same locality, but taken l.ix.18, has been placed in the National 

 Collection. There are also 6 $§ which I attribute to this variety of P. sergenti, 

 though I am not absolutely certain that they belong here ; they bear the following 

 data : Amara, River Tigris, 4,vi.l8, 1 $ ; Mesopotamia, 30.vi.l8, 3 55; Baqubah, 

 River Diayala, 28.vii.18, 1 5 5 Amara, River Tigris, 18.x. 18, 1 5 (biting man)

Phlebotomus signatipennis, sp. nov. 



A small short-legged exceptionally hairy specie , ; easily determined by the 

 strikingly characteristic wing venation, in which the 1st sub-marginal cell is 

 relatively very small indeed, the anterior branch of the vein being about one-fifth 



the length of the vein between the two forks. 



Fig. 4. Phlebotomus siqnaiipennis, Newstead, $ : a, palpus ; 

 h, wing ; the latter drawn to the same scale as the wing of P. sergenti 



in fig. 2, a. 



Female. Relatively robust, short-legged, and exceptionally hairy, the hairs 

 heavily infuscated, more especially those which form the wing-fringe. Hairs on 

 proximal portion of abdomen more or less erect, the longest reaching to the middle 

 of the 4th segment, the rest recumbent on both the tergites and sternites. Leg 

 scales dark leaden grey ; hind tibiae with 4-5 long equidistant outstanding hairs. 

 Antennae with relatively short segments, and densely clothed with long hairs. 

 Palpi (fig. 4, a) relatively short and robust ; 2nd segment rather densely clothed 

 with very long hairs, the longest reaching to about the middle of the succeeding 

 segment ; 3rd strongly incrassate and about twice the length of the 2nd ; 4th 

 narrower, and a little shorter than the 3rd ; 5th relatively very short and about 

 equal in length to the 3rd. Clypeus very short, and widely rounded distally. 

 W ngs (fig. 4, h) narrowly lanceolate, and dist-nctly pointed ; veins unusually 

 thick ; the 1st sub-marginal cell exceptionally small, and placed at a relatively 

 long distance in advance of the tip of the 1st longitudinal vein, the distance
