has its base truncate, not rounded, and the posterior angles are but 

 little produced; in one specimen the thorax is without any 

 markings and the entire underside is flavous, the elytra have also 

 the dark spots less strongly marked. 



Eumolpin.e. 



Miceoheemesia, gen. nov. (group Colaspince). 



Oblong ; antennae filiform, eyes entire ; thorax transverse, the 

 sides angulate and with a narrow margin ; elytra semi-regularly 

 punctured ; legs robust, the anterior femora with a minute tooth, 

 tibiae not sulcate, the metatarsus of the posterior legs as long as 

 the following two joints together, claws appendiculate; prosternum 

 broad, scarcely narrowed between the coxae, its base truncate ; the 

 anterior margin of the thoracic episternum concave. 



In its general appearance, the little species for which I propose 

 this new genus resembles Lefevrea, but differs in the angulate sides 

 of the thorax, which places it amongst the group Colaspince, which 

 up till now had no African representative ; the much broader pro- 

 sternum and the minutely dentate anterior femora separate the 

 genus from Colasjns proper ; the shape of the thorax agrees better 

 with Hermesia, but that genus differs in other details, notably 

 the unarmed femora, although this latter character must be used 

 with caution and only in conjunction with others as a generic 

 distinction. 



Miceoheemesia hieticollis, sp. n. (Plate XX. fig. 7.) 



cS . Below black, base of the antennas and the legs fulvous; 

 thoiax aeneous, closely punctured and finely pubescent ; elytra 

 strongly punctured auteriorly, flavous, the middle with a transverse 

 broad cupreous or aeneous patch. 



$ (?). Above entirely flavous, with a slight metallic gloss. 



Length 2| millim. 



Head aeneous or cupreous, closely punctured and sparingly 

 clothed with short pubescence ; the clypeus not separated from the 

 face, transverse ; antennae slender, extending to about the middle 

 of the elytra, flavous, the terminal joints slightly stained with 

 fuscous, basal joint much thickened, second and third equal in 

 length, fourth and following joints slightly longer and very feebly 

 thickened towards the apex ; thorax twice as broad as long, the 

 sides with a narrow margin and distinctly angulate at the middle, 

 the anterior angles distinctly tuberculate, the tubercle produced 

 and provided with a single seta, the anterior and posterior margins 

 straight, the surface punctured and pubescent like the head; 

 scutellum broader than long, its sides rounded; elytra broader at 

 the base than the thorax, tbe shoulders angulate, the base with a 

 feeble transverse depression, the surface rather strongly punctured 

 in closely arranged irregular rows, with some more minute 

 punctures at the interstices, flavous, with a slight metallic glosfc, 

 the middle of the disc with an irregular, x-ather ill-defmed transverse
