56 MR, M. JACOBY ON NEW GENERA AND [Jail. 3, 



Head with a few fine punctures, flavous, a rhomboidal spot at the 

 middle and one on each side at the base black. Antennre black, 

 the second and third joints and the apex of the terminal one fulvous. 

 Thorax nearly three times as broad as long, the sides very moderately 

 rounded, anterior angles acute ; surface finely and not very closely 

 punctured on the disk, much more closely towards the sides ; a broad 

 subquadrate irregular-shaped black spot is situated at each side, and 

 connected anteriorly with a small round s])ot, another oblong one 

 being placed in the middle of the base. Scutellum black. Elytra 

 extremely closely subrugulose punctate, black, the margins narrowly 

 testaceous, but interrupted at the apex by an elongation of the black 

 portion ; an elongate pear-shaped testaceous spot extends from the 

 middle of the base in an oblique direction to the middle of the elytra. 

 Underside closely pubescent. 



Four specimens of this well marked species are contained in my 

 collection. The design of the elytra and thorax will distinguish this 

 insect from any of its allies. 



Galerucid^,. 

 LuPERODES, Motsch. 



10. Ltjperodes marginatus, sp. nov. 



Oblong, convex, light flavous below. Antennas, their basal joints 

 excepted, piceous. Above pale olive-green, extreme lateral margins 

 of the elytra and their epipleurae black. 



Length 3 lines. 



Hab. Africa, Lagos. 



Head not longer than broad, with a well marked transverse groove 

 between the eyes, finely punctate, the latter black, prominent. An- 

 tennae two thirds the length of the body, obscure piceous, the two 

 or three basal joints flavous, joints 2 and 3 very short, of nearly 

 equal length, the rest filiform and slender. Thorax narrowly trans- 

 verse, its sides straight and narrowed from base to apex, the angles 

 obtuse and rather rounded ; surface like the head, very minutely punc- 

 tured. Scutellum triangular. Elytra convex, parallel, more dis- 

 tinctly punctured than the thorax, of a very pale greenish tint, with 

 the lateral and apical margins black ; this colour is narrowed gra- 

 dually towards the base, where it is very narrow. Underside and legs 

 flavous, finely pubescent ; last abdominal segment in some specimens 

 black. 



Collection Jacoby. 



The genus Luperodes, resembling in its general appearance the 

 gen\xsMonolej)ta, maybe known by the very long first tarsal joint of 

 the posterior legs, the tibiae of which are armed with a long spine, iu 

 connexion with the open anterior coxal cavities. 



11. Ltjperodes atjstralis, sp. nov. 



Oblong, convex, flavous ; apical joints of the antennae, and the 

 breast, black ; elytra minutely punctured, flavous, the base and a 

 small spot below the middle rufous.
