generic rank, should the Metrarginae be found elsewhere. 

 Nesoclimacias is characterized as follows : 



Coriuni laminately dilated, basal sixth strongly contracted; 

 first segment of labium reaching to fore coxae ; pronotum rounded 

 anterolaterally ; eyes subpedicellate, not extending laterally nearly 

 so far as the anterolateral angles of the pronotum. Antenniferous 

 tubercles less acute. Type co7itracta. 



11. M. (N.) lanaiensis sp. nov. 



I have temporarily given this name to the Lanai specimens de- 

 termined by me in 1902 as contracta. PL V. f. 43a, so Dr. Perkins 

 informs me, refers to this. Beyond the labial proportions, as to 

 which I am uncertain, I can say nothing about this, except to 

 point out the differences between the alar venation in this and 

 co7itracta, which may, however, be the Artist's error. 



12. M. villosa F. B. White 



I form a new subgenus, Nesocryptias, for this, characterized as 

 follows : 



Corium not, or only slightly, contracted basally; first segment 

 of labium reaching to base of head. 



Antenniferous tubercles less acute; head and eyes much 

 narrower than the pronotum anterolaterally, the latter rounded. 

 Eyes sessile, small. Membrane small, not, or scarcely, extending 

 posteriorly beyond the apical angle of the corium. Type villosa. 



The typical subgenus, (type nuda) may therefore be charac- 

 terized as: 



Corium not, or only slightly, contracted basally; first segment 

 of labium reaching to base of head. Antenniferous tubercles 

 strongly acute; head and eyes reaching laterally about, or nearly, 

 as far as the anterolateral angles of the pronotum. Eyes subpe- 

 dicellate. Pronotum acutely spined anterolaterally. Membrane 

 well developed.
