propodeon short, transverse, declining, narrower towards its tip: podeon very short: 
abdomen elliptical, shining, depressed above, slightly keeled beneath for about two- 
thirds of its length from the base, much longer but hardly narrower than the tho- 
rax; disc cupreous; metapodeon of moderate length; octoon and following seg- 
ments shorter: legs pale yellow ; coxz and thighs green: wings limpid ; nervures 
fulvous; ulna rather thick, about half the length of the humerus; radius nearly as 
long as the ulna; cubitus shorter than the radius; stigma pale fuscous, of moderate

From the collection of the Rev. G. T. Rudd. 
This species has a larger stigma than Pt. Amyntor (List of Laaletites in 
the British Museum, p. 48) and Pt. linearis (Ent. Mag. iii. 189), to which it 
is allied. It much resembles Pt. semifascia (Ent. Mag. ii. 494), but wants the 
stripe on the upper wing which distinguishes the latter. |
