CHRYSOMELIDJE. 
Closely allied in coloration to banded forms of G. 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 liner 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 emarginate at apex, claws appendiculate. Prosternum 
oblong. Anterior margin of thoracic episternum convex. 
Genus ABIRUS. 
Abirus, Chapuis , Gen. Coleopt. x, 1874, p. 310 ; Lefev. Cat. Fumolp. 
1885, p. 113. 
Type, A. ceneus, Wiedem., from Java. 
Range. India, China, and Malayan Subregion. 
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.

p. clxxv. 
“ Body beneath brownish-seneous, above finely pubescent, 
greenish or cupreous ; labrum, palpi and antennae 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 51-6 mm. 
“ Hab. Hindustan: Rbamnad.” ( Lefevre .)
