Of oblong and convex shape, the head impunctate, the frontal elevations 

 narrowly transverse, not strongly raised, clypens triangnlar, impunctate, palpi 

 slender, the antennae entirely testaceous, two-thirds the length of the body, the 

 third joint one half longer than the second but one half shorter than the fourth, 

 joint ; thorax twice as broad as long, narrowed in front, the sides straight, the 

 surface convex, without impression, closely and finely punctured ; scutellum 

 fulvous ; elytra much more strongly punctured than the thorax, a transverse band 

 at the base of variable width, widened at the sides, the latter (more or less 

 distinctly) and the apex fulvous ; elytral epijilenrae extending below the middle. 



Hai. Kuilu, also Sierra Leone and Cameroous. 



The fulvoQs colour at the base of the elytra is in some specimens rather obscnre 

 and not always well separated from the testaceous ground colour. 



Monolepta africana s]!. nov. 



Black, above pale fulvous, thorax subquadrate, impunctate, scutellum black ; 

 el)i;ra extremely minutely and closely punctured. 



<J. The face with two deep longitudinal excavations, the fourth and fifth joints 

 of the antennae curved, the apex produced. 



? . Lower portion of face smooth, convex, forming a single piece, antennae 

 filiform, simple. 



Length 2^ lines. 



i . Head impunctate at the vertex, the frontal tubercles obsolete, lower portion 

 of face deeply excavated, the excavation divided by a central longitudinal ridge ; 

 palpi black ; antennae two-thirds the length of the body, black, the first joint 

 long and thickened at the apex, the second short, the third twice as long as the 

 second, the fourth and fifth joints equal, the upper margin concave, the ajjcx 

 broadly produced, the following joints slender ; thorax twice as broad as long, 

 the sides slightly narrowed at the base, more rounded iu front, the surface rather 

 convex, impunctate, without depression ; scutellum black ; elytra extremely finely 

 and closely punctured, fulvous, their epipleurae extending below the middle ; 

 underside and legs black, the first joint of the posterior tarsi, half as long as the 

 tibiae ; anterior coxal cavities closed.

In this species the thorax is more transversely shajied' than is generally the 

 case with species placed in this genus ; the curious structure of the head and that 

 of the antennae is a similar exception ; in spite of these diiferences I see no 

 reason to separate the species from Monolepta ; both sexes may be known b)' 

 the structure of the head. The species is apparently not uncommon in the locality 

 where it was obtained. 



Monolepta nig^rita sp. nov. 



Subelongate-ovate, very convex, black, the antennae and legs fulvous ; head 

 and thorax impunctate ; elytra very finely jnmcturcd in semiregular rows. 



Length li line. 



Head impunctate, opaque, the frontal elevations obsolete, eyes large, antennae 

 about half the length of the body, pale fulvous, the terminal joint black, the basal 

 joint long and slender, the second short, the third nearly double the length of
