I am compelled to propose a new species for the male 

 insect above described, on account of the structure of the 

 antenuEe, the length of the wings, the form of the abdo- 

 men, and the want of the ocelli on the fourth segment of 

 that part of the body. I do not know whether we may 

 not already possess the legitimate female. In the general 

 form of the legs it agrees with the male of Ph. cnirifoUum 

 and Ph. Scythe, and, as in those species, the fore femora 

 exhibit traces of the two pale marginal spots.
