Head strongly but not closely punctured, fulvous with an

 round the eyes, the latter not very deeply notched, clypeus and 

 labrum fulvous, antennao black, the lower five joints fulvous, 

 terminal joints distinctiy widened; thorax subcylindrical, very 

 strongly convex, the sides rounded, narrowly margined, posterior 

 angles not at ail produced but acute, the surface entirely impunc- 

 tate, fulvous, the base occupied by a large transverse black band

 gular, raised in front, black, shining ; elytra not depressed below 

 the base, very deeply punctate-striate, the interstices longitudi- 

 nally costate in the maie, less so in the female, impunctate,

Hab. Bengalore, India (my collection). 



G. posticalis seems allied to G. a7ialis Oliv. but is smaller and 

 may be at once known by the spotted or entirely black head and 

 the similarly coloured apical portion of the elytra ; the three 

 spécimens in my collection scarcely differ from each other; 

 G. quadratus Suffr. has a distinctiy punctured thorax and wrin- 

 kled elytral interstices. 



Cryptocephalus inconstans n. sp. 



Black, the basai joints of the antennae and the legs, fulvous, 

 head and thorax fulvous, the latter with two black spots, impunc- 

 tate, elytra strongly punctate-striate, pale fulvous, the basai 

 margin narrowly, the latéral and apical one, broadly, black. 



var. a. Thorax without spots, elytra entirely black. 



var. b. Like var. a but the underside, with the exception of the 

 breast, fulvous. 



Length 1-1 i/a line. 



Head flat, flavous, sparingly and finely punctured, the eyes 

 broadly and angularly emarginate, clypeus impunctate, antennae 

 black. the lower four joints more or less flavous, terminal joints 

 scarcely widened ; thorax strongly narrowed in front, the sides 

 slightly rounded, posterior angles not much produced, the surface 

 entirely impunctate, fulvous, the anterior and latéral margins very
