&. NEWSTEAD — NOTES ON PHLEBOTOMUS, WITH 



sexes, and in its more pointed wings (fig. 3 «, b). It is also, as a rule, larger, but 

 there is a marked range of variation in size, so that this character alone cannot 

 be taken as a guide to its identification. It is moreover generally darker than 

 typical P. mmutus, but in all other respects, including the structural details of 

 the male genital armature it is inseparable from the latter. It may be note- 

 Avorthy to add that Annandale* has described a variety of P. mmutus, Rond., 

 from India under the name niger, and says that it is " darker than the typical 

 form and as a rule larger," though he failed to "distinguish any constant 

 difference in its venation or genitalia." No reference is made to the structural 

 characters of the palpi, neither has he noted any difference in the form of the 

 wing. I am forced to the conclusion, therefore, that the African race is not 

 synonymous with the var. niger, of Annandale. 



Fig. 3. — Wings of Phlebotomus : a, P. minntus var. afrlcanus, Newst., £ ; b, the same, 

 small form, $ ; c, P. minulus, Rond., $ . 



Male. Colour generally much more dusky than that of typical examples of 

 P. minutus, Rond. Upper portion of thorax and abdomen pale smoky-brown ; 

 thoracic hairs erect, dusky greyish, with brownish tips ; abdominal hairs on first 

 and second segments long and erect, forming two small tufts dorsally ; remaining 

 hairs shorter, recumbent and generally uniformly dark brown, being usually much 

 darker than the integument. Wing fringe generally smoky grey with an 

 admixture of darker hairs. 



Proboscis very slightly shorter than the head, inclusive of the clypeus. Palpi 

 (fig. 1 e,f) with the segments 2 to 4, inclusive, each successively longer ; second 

 segment one-third to one-fourth longer than the third ; fifth very variable 

 in length, but usually three to three and a half times the length of the 

 second. Antennae with the third and fourth segments relatively shorter than 

 those in P. minntus. Wings (fig. 3 a, b) lanceolate and markedly pointed ; tip 

 of first longitudinal vein either opposite to, or considerably in advance of, the 

 anterior fork of the second longitudinal vein, so that this character is given to 

 great variation.
