17. Further Note on Flies of the Genus ‘‘ Phlebotomus.” —Recent 
additions to the collection in the India Museum, including a 
number of specimens received from Mr. E, E. Green, enable me to 
supplement, and in one or two points to correct, my former notes 
issued in Vol. VIL. (pp. 57-62) of Spolia Zeylanica, while the 
publication of detailed descriptions of the species found in the 
Maltese islands by Mr. R. Newstead has made it possible to come to 
a decision as regards the identity of P. minutus, Rondani, and my 
own P. babu. In the first place, I may note that the examination 
of a large series of specimens of P. argentipes from different parts 
of India and from Peradeniya in Ceylon shows that the peculiarities 
in venation exhibited by the form I described as P. marginatus, 
great as they appeared to be, are not beyond the limitations of 
variation found in the former species. I have, moreover, taken 
specimens in Calcutta the colouration of which agrees closely with 
that of the form marginatus. Iam therefore forced to the conclusion 
that this form must be regarded merely as a variety of P. argentipes. 
It should also be noted that the figure of P. zeylanicus printed in 
my former paper (p. 60, fig. 4) gives, because of the angle at which 
the wing was drawn, a somewhat incorrect idea of the venation 
in that species; fig. 5 on the same page is more exact in this 
respect. 
As I suggested would prove to be the case, my P. babu is clearly 
identical with Rondani’s P. minutus. Mr. Newstead’s careful 
description and figures (Bull. Ent. Research, II., pp. 62, 69-70, 1911) 
leave no doubt as to this, differences in proportions noted by him 
being evidently due to nothing but the method of preparation and 
examination of specimens. I can confirm his statements in every 
particular from specimens of P. babu examined in a fresh condition 
or preserved in spirit without further treatment. 
The changes proposed in this note therefore are— 
(1) that Phlebotomus marginatus should be known as P. 
argentipes, var. marginatus ; and 
(2) that the name Phlebotomus babu should be sunk in favour 
of P. minutus. 
As regards the former point, it is interesting to note that several, 
perhaps all, species of the genus exhibit a curious colour-dimorphism 
which is apparently not due to season or locality, and certainly 
is not sexual. Thus, P. papatasi exists in Malta, according to
