Soiith African- Coleopterous Fauna. 307 



Shaped somewhat like M. validus, but the prothorax is a little more 

 ampliated laterally ; the elytra are a little more narrowed laterally 

 near the base, the lateral costa is formed by a series of tubercles, the 

 discoidal one is also less carinate and more granulose, and the inter- 

 mediate one is hardly defined, with the exception of a smooth space 

 in the anterior median part of the disk ; the surface is covered with 

 more or less triangular warts not very thick set, but denser along the 

 outer ridge. 



Hab. Zambesia (Buluwayo). F. C. Selous. 



MlCRANTEREUS PROPINQUUS. 



Niger, supra fere glaber $ , ? elytris pube squamosa fulva obtectis ; 

 capitt crebre punctatum ; $ pro thorax vix squamosus, nonnihil 

 rotundato ampliatus, longitudine quarto latior, apice basi haud angus- 

 tior, angulis anticis acutis, sub-prominulis, posticis rotundatis, totus 

 marginatus, parum convexus ; scutellum fere obliteratum ; elytra pro- 

 thorace basi haud angustiora, triplo longiora, ab humeros pone medium 

 sub-oblique ampliata, deinde versus apicem sub-acuminata, pone 

 medium prothorace tertio latiora, margine laterali acuta, apice 

 deplanata, supra sub-plana, postice abrupte dehiscentia, sat crebre 

 verrucosa, in dorso costis duabus e fcuberculis majoribus formatis 

 carinaque laterali verrucosa utroque prasdita ; pedes corpusque subtus 

 ut in M. ambiguo. 



? , a mare differt, prothorace brevissime squamoso pubescente, 

 longitudineque duplo latiore, elytris latioribus, magis ovatis, perparum 

 convexioribus, tuberculis costarum disci magis irregularibus vali- 

 dioribusque, sed ad basim obliteratis. Long. 17-19 mm. ; 

 lat. 9-11 mm. 



Hab. Zambesia (Buluwayo). F. C. Selous. 



The female is less convex than the other South African species, 

 and, although more broadly ovate, has a facies somewhat similar 

 to that of the $ . 



Allied to M. ooampoanus,Per. (Trans. Entom. Soc., 1896, p. 175), 

 but in the $ the two dorsal lines of tubercles are very much better 

 defined, and the ? is not quite so convex nor so abruptly dehiscent 

 behind. 



MlCRANTEREUS PARVULUS. 



Niger, sub-opacus, pube squamosa sub-ochracea sat dense 

 obtectus, antennis, palpis pedibusque rufo-brunneis ; caput crebre 

 puuctatuni ; prothorax longitudine haud latior, antice lateraliter
