R. NEWSTEAD — THE PAPATACt FLIES (PHLEBOTOMUs) 



It was common also during the last week in August at Casa Leoni, the 

 residence of the Hon. E. C. Eoupell, D.S.O., Acting Lieutenant-Governor. In 

 this place it was found most abundantly in a large outhouse which was tenanted 

 by a number 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. Later 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 mucli less active than P. papatast't, though it has the same 

 hopping flight so characteristic of these insects.
