SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 93 



Types of P. asiatica (Michaelsen), 1900, have not, unfortunately, 

 been available for examination, but inasmuch as Michaelsen's reasons 

 for splitting off P. tibcfana from P. asiatica do not appear to be ade- 

 quate — especially in view of the variability of the form under con- 

 sideration — it is quite possible that P. tscJiiliefisis may have to be 

 placed in the synonymy of P. asiatica. The latter is not, however, 

 sufficiently distinguished from P. gnUlehni to warrant further change 

 at the present.
