Distribution. Oriental and Malayan Regions. 



The name of this genus has caused much discussion. Burmeister 

 altered G-uerin's name Aj^hasna to Ajihaaa, a correction \\ hieh has 

 usually been and is here considered justified. Blanchard regarded 

 both these names as preoccupied by Aphanus, Laporte, and 

 proposed that of Penthicas to take its place. This we consider 

 unnecessary. 



Head not protuberant, mucli narrower than pronotum, face 

 slightly narrowed upward or with the lateral inargins parallel and 

 more or less distinctly broadly bisiuuate, disk with two anteriorly 

 diverging carinations and with a more obsolete central carination, 

 clypeuswith a central, sometimes subobsolete, longitudinal sulcatiou, 

 vertex excavate with carinate margins and a central carination, 

 the front broadly upwardly ridged anteriorly and laterally ; pro- 

 notum broader than head, centrally, longitudinally, prominently 

 ridged, its posterior margin trancately sinuate, its posterior angles 

 subangidarly arapliate; mesonotum a little longer than pronotum, 

 centrally, longitudinally moderately carinate ; tegmina moderately 

 broad, the venation on apical areas reticulate ; wings broad, pos- 

 teriorly sinuate, the venation of apical areas moderately furcate 

 and sinuate ; anterior femora not ampliate afc apex, posterior tibiae 

 usually with five spines. 



A. Wim/s luith a green or bluish-green basal ai'ea.

* In selecting the type of this genus we follow Stal, who rightly divided a 

 number of structurally diverse insects included in Ajikana, and founded for 

 their reception several other genera.
