Ohf!. — Described from two specimens. This species belongs to the 

 fulvHs-mirahilis group of Felecorhynchiiti, but may be readily sepai'ated

 the color of the legs. It may be distinguished from P. fidvits, Ricardo, 

 by the rus.'<et colored thorax, abdomen and wings, and by the black legs 

 with yellow tarsi.
