margined ; anterior and posterior angles more or less right angles, 

 rounded, and often bearing a tine seta; upper surface convex, 

 smooth, almost impunctate or very minutely and sparsely punctate, 

 as can be seen under a high power in a suitable light. Scutellum 

 triangular. Elytra slightly broader at the base than the prothorax; 

 surface smooth, very minutely punctate, and sometimes more 

 closely so than the surface of the pronotum ; the punctuation is 

 generally of a mixed character, extremely fine and comparatively 

 stronger punctures of varying degrees of closeness being observable; 

 in some cases the background of extremely tine punctures is 

 conspicuous; lateral margins sometimes slightly explanate before 

 the middle. Underside: the hind femora have a deep channel for 

 the reception of the tibiae on their lower surface ; posterior tibiae 

 somewhat broader towards the apex, with dorsal surface flattened 

 and furnished on the outer side to a certain distance from the 

 apex with a series of minute spinules, generally of a darker colour, 

 while on the inner side there are only fine hairs ; the point of 

 insertion of the tarsus is not at the apex of the tibia, but a little 

 distance before the apex, which is rounded and also set with 

 miuute spinules ; first segment of the tarsus about as long as, or 

 somewhat longer than, the remaining segments, the claw-segment 

 being fairly long ; claws appendiculate. 



In some species the coloration varies considerably ; this is 

 especially the case in those that have transverse coloured bands 

 across the elytra, while in species originally unicolorous such 

 variation is not noticeable. 



Range. India, Ceylon, Borneo, Sumatra, Philippine Is., Celebes, 

 Japan, Australia. 



Baly first introduced the name NonartJira in 1862. Harold 

 in 1875 changed it to Enneamem, on the ground that Baly's name 

 was inadmissible because etymologically it is a hybrid. According 

 to the rules Harold had no right to change the original name 

 except for reasons falling under the law of priority, however 

 incorrect or unfortunate the name may otherwise be. I therefore 

 adhere to the original name Nonarihra.
