The resemblance of this insect to P. varians Perkins is closer 
than that of any of the four other species of the genus known to 
occur on the island of Hawaii. The brown coloration, with macu- 
lation of the limbs very weakly indicated, is closely approached by 
individuals of that species showing the maximum of recessive 
coloration. 
The present species averages larger in size, while in the males 
before us, each slender, straight, lateral projection of the genital 
valves is heavy and armed at the apex with two very minute 
Reetie.

“One or two minute teeth in this position occur, as a rule, in both 
subroseum and varians, but in those species these projections are more deli- 
cate and the teeth are considerably more slender and delicate.
