Hah. Boma, Congo (coll. Belgian Mus. and my own). 

 This small species differs from Thrymnes nucleus Weise in the 

 flavous head and differently coloured antennae and iQgs and nearly 

 impunctate upper surface, and from T. custos likewise in the 

 flavous head and scutellum. T. bifoveatus Weise is black below 

 and has two elytral foveae. 



Podagrica(?) glabrata, sp. n. 



Ovate, widened posteriorly, flavous, the apical joints of the 

 antennae and the elytra, breast, and abdomen black ; thorax with 

 a distinct transverse sulcus, impunctate ; elytra not perceptibly 

 punctured. 



Length 3 millim. 



Head impunctate, flavous, the frontal tubercles small, clypeus 

 widened between the antennae, apical joint of the palpi acute ; 

 antennae filiform, extending to the middle of the elytra, flavous, 

 the last four joints blackish ; thorax transverse, twice as broad 

 as long, the lateral margins distinctly rounded, the posterior 

 angles produced into a small tooth, the surface strongly trans- 

 versely convex, flavous, shining and impunctate, the base with a 

 distinct transverse sulcus, which does not extend to the sides but 

 is bounded laterally by perpendicular grooves or rather turns 

 downwards to the base, another small transverse depression is 

 placed near the anterior angles ; scutellum small, black ; elytra 

 strongly convex and widened behind, much wider at the base than 

 the tliorax, black, shining, with traces of a few extremely minute 

 punctures, only visible with a very strong lens here and there ; 

 legs flavous, all the tibiae with a minute spine ; the breast and 

 abdomen black ; prosternum moderately broad, elongate ; the 

 anterior cosal cavities closed. 



ITab. Malvern, ISTatal (G. Marshall). 



This small species differs from the typical form of Podagrica 

 in its more convex and ovate shape and in the thoracic transverse 

 sulcus. In the absence of other similarly structured species, 

 however, I have iov the present included the insect in Podacjrica, 

 to which at all events it is very closely allied. The elytra have a 

 very narrow lateral reflexed margin, which is accompanied by a 

 row of punctures, the only ones visible ; the metatarsus of the 

 posterior legs is as long as the following two joints together. 



Crepidodera ZAMBrENSis, sp. n. 



Elongate, fulvous ; head and thorax remotely and strongly punc- 

 tured, the latter transversely sulcate ; elytra dark blue, strongly 

 punctured, the interstices longitudinally costate throughout. 



Length 5 millim. 



Of elongate and parallel shape, the head broad, strongly and 

 remotely punctured at the vertex, the latter fulvous, lower portion 

 of the face paler ; frontal tubercles in shape of narrow transverse 

 ridges, clypeus with an acute central ridge ; antennae rather long 

 and slender, fulvous, the basal joint elongate, thickened at the
