lowisli. except thai the caudal face of the ce})haHc femora shows 

 a weak l)hin"e(l suffusion of Ijrown mesad. A larg'e number of 

 specimens so mari-ced have the tibiae all lii^htly and inconspicu-

 specimens at hand.

 ticular interest in being fully macropterous — a very rare condition 

 in the species.'^ 



Not only is the species generally abundant in the Hawaiian 

 islands, but it has also been recorded from the islands Palmyra 

 and Laysan.
