Arrnenosoma atntm, n. sp. 



Oblongum, atrum, sat convexum, supra confertissime subtilissime 



punctulatum. 

 Long. 8-12 millim. 



Dull black. Thorax broadest in the middle, scarcely nar- 

 rowed at the base, with some fine punctures scattered over 

 the disk, more closely punctured at the sides ; generally with 

 a very shallow long-itudinal impressed line in the middle. 

 Elytra with some obscure striai, the punctures which form 

 them being elongate and linear. Middle of the prosternum 

 shining, finely and sparingly punctured. Sides of the abdo- 

 men rather closely punctured, the first to fourth segments 

 each with a smooth spot at the side. Tibise slender, tinted 

 with coppery, beset with lines of short black setje. 



Hah. Cape of Good Hope. 



Discoderes Jiumeralis, n. sp. 



jEneus ; thorace intequali ; elytris unicostatis, humeris laete rufo- 

 cupreis, regione scutellari cyanea, postice fasciis undulatis duabus 

 albidis, apico fulvo-pubescente. 



Long. 16 millim. 



Head deeply longitudinally impressed, with short fulvous 

 pile between the eyes. Thorax very broad, sloping down in 

 front, declivous at the sides, very closely and finely punc- 

 tured, with a small impression in front and a large shallow 

 one behind the middle ; each side has a large irregular im- 

 pression which is pubescent in the middle, and outside this 

 there is a shining flexuous ridge which forms afigure resembling 

 a 5. There are two small spots of dark brown pile on each 

 side of the disk. Scutellum smooth, gently concave, trian- 

 gular. Elytra as broad as the thorax, narrowed about the 

 middle and then much wider at one quarter from the apex. 

 The shoulders are raised and slightly prominent, steel-blue 

 beneath, coppery red above. Rather before the middle there 

 are several whitish spots which form a kind of interrupted 

 fascia ; behind the middle there is a zigzag fascia, and 

 another near the apex ; the space between the bands is very 

 dark brown. 



Hah. Madagascar. 



Maschalix, n. g. 



General characters of Amorpkosoma, but relatively much 

 shorter and broader; thorax broadest just before the base, 

 narrowed anteriorly. Elytra a little wider than the thorax,
