very broad and concave, under side and legs black, shining, libiae 

 without emargination, the first joint of the posterior tarsi as long 

 asthe followlng one, claws strongly swollen, prosternum narrow. 



Madagascar. 



This, and I think ail tlie other species of Oedîonychis (described 

 as sucii) from Madagascar liad mucli better find their places in the 

 présent genus on account ofthe simple tibias and extremely broad 

 elytral epipleurse. H. nigroscutata cannot be mistaken for any other 

 similarly coloured species on account of the black scutellum and 

 the sharp elytral costse, this latter structure is not peculiar to the 

 maie only but is also found in the female ; in the former sex the last 

 abdominal segment is trilobate with the médian lobe concave, in the 

 female the same segment is triangularly emarginate. 



HYPHASIS SIMILIS n. sp. 



Testaceous, shining, the terminal seven joints of the antennae and 

 the scutellum black, thorax impunctate, with broadly flattened 

 sides, elytra closely and finely punctured, the base not raised. 



Length 6 mill. 



Head impunctate, depressed between the eyes, the space between 

 the latter transversely grooved, frontal élévations obsolète, clypeus 

 perpendicularly depressed, palpi incrassate, antennae with the 

 terminal five joints widened, black, the lower four joints fulvous, 

 the basai joint widened anteriorly, the second, half the length of the 

 third ; thorax nearly three times broader than long, the sides 

 strongly rounded and very broadly flattened, the anterior angles 

 slightly dentiform, the surface impunctate, very shining, the base 

 with a rather deep but short dépression in front of the scutellum, 

 the latter part black; elytra with a very shallow dépression below 

 the base, minutely punctured, their epipleurse very broad; below 

 and the legs entirely testaceous or pale flavous. 



This species is closely allied to the preceding one, but is certainly 

 distinct; the antennse are differently coloured as well as the legs 

 and the under side, the elytra bave the base not raised and bave no 

 costse, the trilobate last abdominal segment of the maie, has the 

 médian lobe flat and not concave. Of both species I bave two 

 spécimens before me. 



PHYSOMA KLUGI n. sp. 



Fulvous, shining, antennse black, the basai joints fulvous, thorax 

 transverse, impunctate, the sides flattened, elytra finely and 

 closely punctured. 



Length 8 mill.
