jection. Venation: much as in Glaucoptcryx ; but the discal venules are 

 situated within the middle of the wing, while in Glaucopteryx they are with- 

 out, and, consequently, the median venules are longer than in that genus; 

 two subcostal cells; posterior discal veins regularly curved; the first medial) 

 venule arises nearer the second than in Glaucopteryx. Hind legs with the 

 tarsi shorter than the tibiae. Ahdonien moderately long, with a short, square 

 anal tuft. Coloration: entirely different from Glaucopteryx, the species being 

 reddish in the female, with numerous line, distinct, wavy lines, and some- 

 times a conspicuous white discal ringlet. The sexes differ much in color. 



The species of this genus differ from Glaucopteryx in their color and 

 smaller size, the long, slender palpi, and narrow trout of the head. 



Iliibner mentions only P. gemmata and P. Jluciata under this genus. It 

 should clearly have the priority over Camptogramma. 



Larva. — "Of medium length, not attenuated, flattened above, laterally

 and a rounded anal flap; head small and subglobular; living on low plants.
