94 MR. M. JACOBY ON THE [Feb. 1, 



indicated only near the middle by a thickened rounded fovea ; the 

 surface scarcely visibly punctured. Elytra very convex, deflexed and 

 pointed at the apices, without any basal depression or prominent 

 shoulders, the surface punctured like that of the thorax. Body 

 below coloured like the upper surface ; the tibite and the tarsi more 

 or less distinctly flavous. 

 Dikoya, Bogawantalawa. 



Ph^lota (gen. nov. Halticlnorum). 



Body ovate, convex, subcylindrical, pointed posteriorly. Antennae 

 rather distant, gradually thickened at the terminal joints. Thorax 

 transverse, the sides rounded, the anterior angles thickened and 

 obliquely rounded, the disk without depression. Elytra punctate- 

 striate. Anterior tibise unarmed ; the posterior ones with a very 

 chort spine, somewhat widened at their apices, and with a short and 

 shallow longitudinal depression or groove ; the first joint of the 

 posterior tarsi as long as the two following joints together ; claws 

 appendiculate. Prosternum broad, its base truncate. Mesoster- 

 num of the same shape but half the size. Anterior coxal cavities 

 closed. 



Phcelota, like Ghabria, has much the general appearance of a spe- 

 cies of Chrysomela ; from Chabria it differs in the shorter anteiuiae, 

 the punctate-striate elytra, and the closed coxal cavities. 



Ph^i.ota semifasciata, sp. nov. 



Fulvous or piceous ; above obscure greenish aeneous varied with 

 fulvous ; thorax minutely punctured, the disk greenish ; elytra 

 regularly punctate-striate, greenish aeneous, the interstices alternately 

 more or less obscure fulvous. 



Var. Above and the legs entirely fulvous (immature ?}. 



Length 2 lines. 



Head with a few minute punctures ; eyes large ; frontal tubercles 

 transversely trigonate, nearly contiguous ; the carina indistinct ; 

 labrum more or less fulvous. Antennge half the length of the body, 

 the five lower joints fulvous, the rest black, the apex of the terminal 

 joint fulvous ; the second to the fifth joints short, nearly equal, the 

 six terminal ones thickened, slightly longer than broad. Thorax 

 transverse, the anterior margin nearly straight, the posterior one and 

 the sides slightly rounded, the anterior angles much thickened and 

 obtusely rounded, the surface minutely punctured, greenish aeneous, 

 the marginsmore or less fulvous. Elytra very convex, subcyhndrical, 

 and pointed at the apices, strongly punctate-striate. Legs piceous 

 or fulvous, more or less stained with greenish aeneous. 



Bogawantalawa. 



In some specimens the elytra show alternate longitudinal bands of 

 aeneous and fulvous. 



Pexodorus (gen, nov. Halticlnorum). 



Body ovate, widened behind ; palpi slender, filiform. Antennae 

 filiform, the second joint short, the third and fourth joints equal.
