APHTHONA SUMATRANA. 207 



rax testaceous; head dark metallic greeu; elytra closely- 

 punctured, metallic greenish aeneous; posterior femora pi- 

 ceous. — Length 1^/4 line. 



. Head smooth, impunctate; frontal tubercles in shape of 

 a narrow transverse ridge; carina acutely raised; antennae 

 two thirds the length of the body , the third joint scar- 

 cely longer than the second , 3 lower ones fulvous , the 

 rest piceous or black ; thorax transversely subquadrate , the 

 sides straight , obliquely shaped at the posterior angles , the 

 anterior ones acute, surface impunctate , fulvous or testaceous 

 (in one of the 3 specimens with a metallic greenish gloss), 

 scutellum and elytra dark metallic green, the latter very 

 closely , finely but distinctly punctured ; posterior tibiae 

 piceous , rest of the legs testaceous ; posterior tibiae mu- 

 cronate , their first tarsal joint as long as the 2 following 

 joints together. 



Anicera , nov. gen. 



Body oblong ; eyes large , convex , entire ; palpi slender , 

 filiform; antennae elongate, rather robust, the second and 

 third joints very short , equal , fourth joint longer than the 

 3 preceeding ones together ; thorax transverse , without any 

 depressions; scutellum triangular; elytra oblong, semipunc- 

 tate-striate , their epipleurae indistinct below the middle ; 

 posterior femora moderately thickened , their tibiae straight , 

 not channelled and unarmed ; posterior first tarsal joint 

 rather longer than the two following ones united; claws 

 appendiculate ; prosternum extremely narrow ; mesoster- 

 num elongate , its apex pointed ; anterior coxal cavities 

 closed. 



This genus seems to be an intermediate form between 

 Chaloenus and Oxygona and having the general appearance 

 of the latter; the structure of the antennae, in which the 

 second and third joints are very short, will separate the present 

 genus from either. Sutrea Baly , which also resembles in shape 

 and coloration the genus here proposed , is at once distin-
