* P. pnmiosMsPasc, is impossible to identify from the description; so far 

 as it goes, however, it must be very near P. abdominalis Lea, which may 

 prove to be synonymous with it. The " fine uniform whitish exudation" 

 mentioned by Pascoe, is common to many species of the genus in fresh 

 specimens. P. Darwiniensis Macl., as suggested by its author, shows a 

 decided affinity to the insects of Section ii., in its narrow margins. It 

 seems out of place in the above P. fraternus Bha.ekh., (if identified cor- 

 rectly by me), also from description, from its small size, and nearer affinity 

 to forms like F. vicarius Pasc, seems more at home in AIacleay"s Section iii. 



t P. Reichei Breme, is unknown to me, and may be an abraded form of 

 /'. hirtus Macl. At least nothing is said in the description as to pilose 

 clothing.
