 rectis ; elytris apicern versus externe denticulatis, hie illic

[Long. 11-12, lat. 6£-6£ lines. 



Maris clypeo antice sat fortiter sat anguste producto, tibiis 



anticis externe apicem versus bidentatis, dente altero minuto 



in medio instructis. 



Feminse clypeo antice rotundato, tibiis anticis externe 



tridentatis. 

 N.B. — Cujusdam ex exemplis femineis meis tibiae anticse 



externe subsimplices sunt. 

 The clypeus of the male narrows forward evenly for much more 

 than half its length, and thence is almost parallel-sided, so that it 

 is very much narrower across the apex than across the base ; it 

 scarcely differs from that of A. Boisduvali, Dup., except in having 

 its front margin more arched ; it also resembles the clypeus of 

 rugosus, Kirby (male), but in that species the produced apex (i.e., 

 the piece beyond the level of where the sides cease converging 

 forward) is evidently wider, shorter, and more truncate. The 

 puncturation, sculpture, and pubescence are almost as in A. 

 Odeivahni, except that the pubescence is less dense in the specimens 

 before me (possibly the result of abrasion), that the sutural apex 

 of each elytron is produced into a slender and well-defined spine 

 about or nearly as long as the width of the levigate space that 

 runs down the elytron close to the suture, and that the external 

 margin of each elytron for a short distance a little behind the 

 middle has a fringe of well-defined sharp denticulations. The 

 prothorax is unusually short in appearance owing to its base 

 being scarcely lobed in the middle, but might rather be called 

 " gently tri-sinuate " ; in all, or nearly all, the other species of the 

 genus the middle part of the base of the prothorax reaches a good 

 deal further backward than the hind angles, but in this species 

 the middle part is very nearly on a level with the hind angles; the 

 prothorax thus being very small, the head appears proportionately
