HOPLASOMA APICALIS. 233 



NOTE XXXIII. 



DESCRIPTION OF A NEW GENUS AND 

 THREE NEW SPECIES OF MALAYAN GALERUCINAE. 



MARTIN JACOBY. 



Hoplasoma , nov. gen. 



Body elongate ; eyes round , entire ; penultimate joint 

 of palpi thickened; antennae slender, filiform, second joint 

 very short, fourth joint longer than the third; thorax 

 squareshaped , disk transversely depressed at the posterior 

 half; scutellum subpentagonal ; elytra elongate, very finely 

 and semiregularly punctured, with some obsolete longitu- 

 dinal costae ; their epipleurae very narrow , extending to 

 the apex; legs rather robust, tibiae unarmed; the first 

 posterior tarsal joint as long as the two following united ; 

 claws deeply bifid; prosternum invisible between the thighs ; 

 anterior coxal cavities open. 



In its general shape and squareshaped thorax, the spe- 

 cies upon which I am obhged to found the present genus, 

 resembles Phyllohrotica to which it is without doubt clo- 

 sely allied but at once distinguished by the deeply bifid 

 claws ; the epipleurae also , although very narrow, are never- 

 theless distinct and the second joint of the antennae is 

 shorter than is generally the rule in the allied genus. 



Hoplasoma apicalis , n. sp. 



Testaceous or fulvous; thorax impunctate; elytra scar- 

 cely visibly punctured, their apical third portion black. — 

 Length 4 — 4^3 lines.
