broad in the middle, the basal abscissa of the radius a 

 little longer than the second, which is straight, oblique and 

 not curved. The second cubital cellule at the top more 

 than twice the length of the third ; at bottom not much 

 longer than it ; the third cellule very much narrowed at the 

 top ; the transverse cubital nervures being almost united ; 

 the first recurrent nervure received quite close to the apex 

 of the wing ; the second a little before the middle ; it is 

 elbowed in the middle. Legs densely pruinose ; the spines 

 long ; the long spur of the hind tibiae reaching before the 

 middle of the metatarsus : the claw with a blunt, thick 

 subapical tooth. 



This species forms a transition to Ferreola^ the apex of 

 the median segment being only moderately concave and 

 hardly dilated at the sides ; the antennae, too, are higher 

 up over the clypeus, and the anal nervures in the hind wings 

 are received beyond the cubital. In one example the third 

 cubital cellule is distinctly petiolated. 



Length 12 mm. 



P. Wroughtoni has the apex of the median segment 

 more as in the typical FerreolUy i.e.y it is produced laterally, 

 but not quite so much as in, say, Circe^ it forming, in fact, a 

 regular curve, and it is also depressed in the middle ; the 

 abdomen is compressed, the anal nervure in the hind wing 

 is interstitial ; the antennae are placed immediately over 

 the clypeus ; the head is very little developed behind the 

 eyes ; the basal nervure is not interstitial ; the centre of 

 scutellum not much, if any, narrowed towards the apex — 

 the pubescence on the edge of the pronotum forms a 

 whitish band.

Very similar to P. Rothneyi^ having the same grey pruinose 

 vesture, with the abdominal segments grey and black ; and 

 the apex of the median segment concave, the head very
