362 CHRYSOMELID.E. 



Group CALLISIXI. 



Head oblong, partly exserted ; antennae with terminal joints 

 more or less strongly dilated or moniliform. Thorax transverse, 

 subquadrate, of equal width, sides angulated at the middle. Elytra 

 short, oblong, basal portion rather strongly raised. Tibiae of the 

 intermediate and posterior legs emarginate at apex ; claws appen- 

 diculate. 



Principally distinguished by the structure of the antennae and 

 tibiae, the angulate sides of thorax and equal width of latter. 



Key to the Genera of Callisini. 



a. Antennae with terminal joints broadly dilated ; 



femora toothed beneath CALLISINA, p. 362. 



b. Antennae with out dilated terminal joints, monili- 



form ; femora not toothed beneath EDISTUS, p. 365. 



Genus CALLISINA.

Type, C. fasciata, Baly, from Malacca. 



Range. India ; Cambodia ; Malayan Subregiou. 



Oblong, convex. Head exserted; eyes prominent, sinuate below; 

 apical joints of antennae strongly dilated and flattened, terminal 

 three as broad as long. Thorax transverse, convex, margined at 

 the sides. Scutellum subtrigonal, apex rounded. Elytra oblong, 

 wider than the thorax. Legs robust ; femora incrassate with acute 

 tooth beneath ; first joint of tarsi shorter than the following two 

 united ; claws appendiculate. 



This genus is not closely allied to any other and certainly not 

 to Corynodes as Baly states, to which it has only a superficial 

 resemblance in shape : the head is without ocular sulci and the 

 thoracic episternum is concave instead of convex. 



641. Callisina brunnea, sp. n. 



Dark brown ; antennae (basal joints excepted) and legs black. 



Head rather strongly and closely punctured, with central groove 

 on the vertex; clypeus punctured at base, sides with a deeply 

 punctured short groove ; space above eyes sulcate, longitudinally 

 strigose ; antennas extending to middle of elytra, basal three 

 joints fulvous, third and fourth equal, terminal joints elongate, 

 very moderately thickened. Thorax subquadrate, transverse, not 

 narrowed anteriorly, sides feebly rounded, strongly angulate at 

 the middle, a deep medially interrupted sulcus near anterior 

 margin, disc rather strongly but unevenly punctured. Elytra 

 wider at base than the thorax, oblongj subcylindrical, transversely
