Antennae with the long hairs extending to the tip, the third to the ninth 

 segments, iuchisive, 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 recmnbent 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

 of whirling round and roimd with great rapidity, so rapidly at times as to render 

 itself almost invisible.
