Further Notes ox Indian Phlebotomi. — The recent acquisi- 

 tion of a number of specimens of Phlehotomus from different parts 

 of India and especially from Ceylon enables me to amplify the 

 notes published in these "Records" last year (vol. iv, No. ii, 

 pp. 35 — 52), and I have been helped greatly to gain a true apprecia- 

 tion of certain characters by frequent discussions with ^Ir. E. 

 Brunetti. 



Hitherto I have laid great stress on the relative lengths of the 

 different parts of the second longitudinal vein as a specific charac- 

 ter, but these lengths are evidently more variable than I thought. 

 They would provide a method of separating a species such as 

 P. himalayensis from one such as P. argentipcs at a glance, but in 

 the latter the length of the upper branch of the vein, and conse- 

 quently that of the other parts also, varies within fairl}^ wide limits. 

 I have had, therefore, to recognize that the form recently described 

 by me as P. marginatus is not a " good " species but merely a 

 colour variety of P. argentipes. 



Regarding the sanitary importance of Phlehotomus attention 

 may be directed to a paper just published b}' Major F. Wall, 

 I.M.S.^ The facts cited suggest (i) that troops moved into certain 

 barracks in Chitral become infected with a fever akin to or 

 identical with what is called Papatacifieber in Austria, these 

 barracks being frequented by P. papatasi and P. babu, and (2) 

 that men from districts in w4iich these two species occur are less 

 liable to suffer from this fever (having perhaps become to some 

 extent immune) than those from districts in which the common 

 species are P. ma joy and P. himalayensis.

1 have recently examined a good many specimens from Pera- 

 deniya, which is situated in the interior of Ceylon at an altitude of 

 about 1,500 feet. The species occurs all over the plains of India 

 except in the extreme north-west. Apparently it does not occur 

 in the Himalayas.

This form cannot be regarded as more than a colour variety, 

 distinguished from the typical form of P. argentipcs by the fact 

 that the dorsum of the thorax is brown instead of black and the 

 sides of the thorax rather darker than in the tjq^ical form. 



The var. marginatus occurs in Calcutta as well as at Pera- 

 deniya and is apparently not a seasonal form.
