Species 42-46 have black bodies, very richly ornamented with a brilliant silvery 

 pubescence ; the wings violaceous, or yellowish, or hyaline banded with fuscous. In 

 two of the species known to me (P. gloriosus and P. vercepacis) neither the basal nor 

 the anal nervure is interstitial; the claws are almost bifid; the legs very long, with 

 the long spur of the hind tibiae short compared to the length of the metatarsus. 



/ The basal and anal nervures not interstitial. (Species 42, 43.)

Deep black, bearing a brilliant silvery pile, especially thick on the face, pleurae, and 

 median segment, and on the third and fourth abdominal segments. Antennae stout, 

 convolute, longer than the head and thorax united ; eyes very slightly converging at 

 the top ; the hinder ocelli separated from the eyes by hardly half the distance they are 

 from each other; clypeus with the sides oblique, the apex projecting, slightly incurved. 

 Prothorax shorter than the head, the apex bluntly rounded ; in front of the tegulae at 

 the top there is a hollow. Scutellum raised, a little narrowed towards the apex. 

 Median segment with a gradually rounded slope to the apex, without a central line, and 

 covered with long soft pale hair. The sternum before the middle coxee projects into a 

 blunt tooth. Abdomen as long as the head and thorax united, subsessile ; the pygi- 

 dium rough and covered with stiff dull rufous pile and with some long black hairs ; 

 the four apical ventral segments bear long black hairs. Legs long; all the claws 

 sub-bifid ; the fore tarsi without spines, only shortly ciliated beneath ; the tibial spines 

 very short ; the long spur of the hind tibiae about one-fourth the length of the meta- 

 tarsus. The third cubital cellule much longer than the second; the basal nervure not 

 interstitial ; the anal nervure in hind wings interstitial. 



The male is similarly coloured to the female. It has the antennae straight, mode- 

 rately thick, tapering towards the apex, the apical joints curved and a little dilated,
