456 CHIITSOMELID^. 



Closely allied in coloration to banded forms of C. villosulum, 

 Lefev., but without any pubescence, the thorax perceptibly more 

 strongly punctured and the punctures more widely separated ; 

 also much like C. downesi, Baly, but in that species the elytra! 

 rugosities do not extend so far inwards nor downwards and the 

 puncturation is finer and closer, also the elytra are without the 

 narrow cupreous bands. 



Group EDUSINI. 



Elongate, head immersed in thorax. Thorax subconical with dis- 

 tinct lateral margins. Elytra generally transversely rugose at sides. 

 Tibiae not emargiuate at apex, claws appendiculate. Prosternum 

 oblong. Anterior margin of thoracic episternum convex. 



Genus ABIRUS. 



Abirus, Chanuis, Gen. Colcopt. x, 1874, p. 310 ; Lefev. Cat, Eumolp. 

 1885, p. 113. 



Type, A. ceneus, Wiedem., from Java. 



Range. India, China, and Malayan Subrcgion. 



Characters those of the group. Body elongate and subcylindrical, 

 with strongly developed elytral rugosities, sometimes pubescent 

 above. Antennae with terminal joints more or less widened. 

 Thorax broader than long, with rather straight sides and pointed 

 anterior angles. Legs somewhat robust ; tibiae gradually but 

 slightly widened towards apex; first joint of tarsi triangular, 

 shorter than the following two united ; claws appendiculate. 



The forms in this genus are very similar in shape and appear- 

 ance to those belonging to the genus Dermorhytis, but differ in that 

 the sides of thorax are not angulate and the anterior margin of 

 the episternum is convex not concave. 



795. Abirus angustatus, Lefev. Bull. Soc. Ent. France, 1887, 

 p. clxxv. 



" Body beneath brownish-aeneous, above finely pubescent, 

 greenish or cupreous ; labruin, palpi and antenna brownish- 

 testaceous, tarsi blackish. 



" Oblong- elongate, parallel-sided. Head densely substrigosely 

 punctured. Thorax nearly twice as long as broad, densely punc- 

 tured, punctures uneven in size. Elytra below base scarcely 

 perceptibly impressed, regularly punctate-striate near suture, 

 outer disc densely transversely substrigose, very minutely 

 pubescent towards apex. 



" Length 5^-6 mm.
