1. Vertex angularly emarginate at apex Kirhi/ona 



Vertex truncate at apex 2 



2. Vertex with a distinct transverse keel Leplovlamys 



Vertex without a transverse keel 3 



3. Vertex with a distinct medio-longitudinal keel, 



quadrate, base subequal to apex Ptolcria 



Vertex without a medio-longitudinal keel, or with 



a very obscure one 4 



4. Vertex distinctly wider than long, base shallowly 



and roundly emarginate AiistroJoma 



Vertex not distinctly wider than long, base less 

 roundly emarginate 5 



5. Apex of vertex not perceptibly narrower than base i^acrlntrias 

 Apex of vertex narrower than base, the median 



facial keel breaking the truncate outline of apex. . Di/stheatias 



I cannot find the type material of 8acch arias among the late 

 Mr. Kirkaldy's collection, but I took specimens in Java which 

 I consider to be topotypes ; they agree with the specific descrip- 

 tion, his generic description being quite inadequate. 



The above six genera are closely allied, the first three are 

 easily distinguished, but the last three are very difficult to keep 

 apart; their generic distinctions are not likely to bear the strain 

 that more extensive collecting will place upon them. 



Ffolena Stal. 

 (1) P. (jraniiliiiervis sp. nov. (59) 



Lateral carinae of scutellum sinuate. 



Light brown, the keels on head and thorax slightly lighter, dorsal 

 part of abdomen fuscous, front legs with faint fuscous rings on 

 femora and tibiae; tegmina light brown, small brown granules cover- 

 ing nerves, darker over stigmal spot; wings hyaline, slightly fuscous, 

 veins brown. Male pygophor laterally compressed, a large emargina- 

 tion on dorsal side in which the anal segment fits, lateral edges 

 sinuate, a small, rounded, median process; anal segment longer than 

 broad, anus a little beyond middle, beyond anus flattish, slightly 

 turned down, truncate at apex, a small, down-turned spine at each 

 apical corner; styles flattish, widest at apex, inner edge convex outer 

 edge concave, apex with a small point.

 portion of tegmina.
