70 R. NEWSTEAD—THE PAPATACI FLIES (PHLEBOTOMUS) 
Antennae with the long hairs extending to the tip, the third to the ninth 
segments, inclusive, with geniculated and paired spines. Palpi as in the male. 
Length, 2 mm. 
The distinguishing characters of this insect are its relatively small size, 
especially in the male ; the recumbent abdominal hairs ; the short third antennal 
segment ; and the marked character of the palpi. The male may be easily 
distinguished also by the form of the external genitalia.

The first two examples were captured by Major F. L. Dibblee, Royal Marine 
Artillery, at his residence at Sliema, August 20th, 1910; and two additional 
specimens were taken by myself, one at Casa Leoni, in a rabbit hutch, 
August 31st ; the other at Floriana, August 27th. 
In captivity Ph. minutus is much more active than any of the other Maltese 
species, and when confined to a small area was almost incessantly moving from 
place to place. Apart from its flea-like actions it also has the remarkable habit 
of whirling round and round with great rapidity, so rapidly at times as to render 
itself almost invisible.
