A handsomely striped species, still rare in collections. Fig. 

 35 is. from one of Ferussac's original figures. Fig. 36 after 

 Reeve, 33 after Kobelt, and 34 from Morelet, further illus- 

 trate it. Lamarck gave the locality Peru for his B. richii; 

 and Lubomirski (P. Z. S., 1879, 725) records P. flammigera 

 from Chota, Peru, where it was collected by Stolzmann. 

 This must be a misidentification of some superficially similar 

 species of Oxystyla.
