The resemblance of this insect to P. T'arians 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 

 teeth."

*" One or two minute teeth in this position occur, as a rule, in both 

 suhroscum and varians, but in those species these projections are more deli- 

 cate and the teeth are considerably more slender and delicate.
