 O. Lower; November 11th, 1902. 



Type in Coll. Tillyard. Unique. 



Closely allied to Pr. venustnm Gerst., from which it can be 

 at once distinguished by its shorter wings, shorter and stouter 

 abdomen, and by the lack of the strikingly beautiful effect of the 

 pattern of the forewing, from which Gerstaecker's species re- 

 ceived its name Pr. erem'u^'iH possibly a dwarfed, inland species 

 geminate with P. venustnm, \Vhich appears to be confined to the 

 coastal strip and eastern river- valleys.

 at a level proximal to that of the cubital fork.
