femora very strongly incrassate, their tibise straight, distinctly 

 sulcate, widened posteriorly, \Aith a strong spur placed at the 

 middle ot the apex, their metatarsus as long as the following three 

 joints together, claws appendiculate ; prosternum narrowly elon- 

 gate, mesosternum i.arrowly transverse ; tlie anterior coxal cavities 

 closed. 



Amongst the genera with closed anterior coxal cavities 

 there is only one which has the eyes surrounded by a similar 

 although broader sulcus — the genus Orthaa Jac. from Burmah. 

 But in addition to this character the thorax in the latter genus is 

 also provided with perpendicular grooves at the base, which are 

 absent in the genus characterized here, and in wliich the metatarsus 

 of the posterior legs is also proportionately longer and the antennae 

 have more elongate joints. 



HaLTICELLA riAYOPUSTUlATA, sp. n. 



Eounded, convex, fulvous ; antennae and the anterior legs flavous ; 

 horax closely and finely punctured ; elytra closely punctured, with 

 bsolete rows of deeper punctures, obscure piceous, a transverse 

 •<pot near the middle and another near the apex flavous. 



Length 2| millim. 



Head finely punctured, with a narrow sulcus above the eyes, 

 fulvous with a slight metallic gloss ; the clypeus separated from the 

 face by a narrow transverse groove, frontal tubercles absent ; palpi 

 slender, flavous ; antennae not extending to the middle of the elytra, 

 flavous, the second and third joints of equal length, the following 

 slightly longer and thicker ; thorax nearly twice as broad as long, 

 the sides nearly straight and obliquely narrowed towards the apex, 

 the posterior margin rounded, the anterior angles slightly thickened, 

 the surface closely and distinctly punctured, fulvous, the disc 

 rather darker ; elytra ovate, convex, and pointed at the apex, 

 punctured in the same way as the thorax, but with obsolete rows 

 of stronger punctures, more strongly marked at the sides, where 

 the last two interstices are slightly longitudinally costate, the disc 

 oE an obscure piceous colour, a rather large slightly oblique spot 

 placed close to the middle and another smaller one near the apex, 

 obscure flavous ; posterior femora strongly incrassate, pale piceous, 

 the anterior legs flavous. 



Hah. Natal, Frere. I received two specimens from Mr. Perin- 

 guey. 



GaLEETJCINjE. 



Idacantha weisei, sp. n. (Plate XXI. fig. 4.) 



Flavous, the antennae (the basal joints excepted), the breast, and 

 the legs black ; thorax sparingly punctured at the sides ; elytra 

 black, nearly nnpunctate. 



Alas. The third joint of the antennae broadly dilated and ex- 

 cavated ; the scutellum with the sides raised into strong ridges, 

 the apex reflexed ; the elytra with two ful\ous tubercles at the 

 basal margin.
