72 R. NEWSTEAD—THE PAPATACI FLIES (PHLEBOTOMUS) 
It was common also during the last week in August at Casa Leoni, the 
residence of the Hon. E. C. Roupell, D.S.O., Acting Lieutenant-Governor. In 
this place it was found most abundantly in a large outhouse which was tenanted 
by anumber of rabbits. In the early mornings, shortly after 6 a.m., numbers of 
sand-flies were found chiefly in the corners of the room, but many were also 
seen sitting about the walls in various places, though chiefly at the junction with 
the ceiling. ater in the day they were rarely seen in these situations ; but 
examples could always be found in the dark earthen pots which were used, and 
generally occupied, by the rabbits as retreats.

The male is easily distinguished from that of P. papatasii by its generally 
smaller size, shorter legs, and much smaller genital armature, which is little more 
than half the width of the abdomen. The female may also be distinguished by 
its shorter legs, and generally darker colour. After a few hours in captivity it 
also becomes generally much less active than P. papatasz, though it has the same 
hopping flight so characteristic of these insects.
