Acmocera and Acridoschema. 



These two genera of Thompson's are pnt together in the Munich Catalogue. 

 They are perfectly distinct, differing in all the species known to me (all that are 

 described) as follows. 



I. Acmocera. End-segment of antenna modified, short, glossy, curved, pointed. 

 Spine of pronotnm submedian. Femora clubbed, anterior femur angulate or dentate 

 in S . Here belong : — 



Acmocera ohjinpiana (1858) Thoms. 

 Acmocera antkriboides (1858) Chevr. 

 Acmocera compressa (1782) Fabr. 

 Acmocera undulata (1882) Qned. 

 Acmocera inermis (1858) Thoms. 

 Acmocera bifasciata (1878) id. 



I am not convinced of the distinctness of compressa and antkriboides. 



II. Acridoschema. End-segment of antenna long. Spine of prothorax snbbasal. 

 Femora not obviously compressed, slenderer than in Acmocera, anterior femur of S 

 not angulate or dentate above. Third segment of antenna mostly tufted at end. 

 Here belong : — 



Acridoschema isidori (1858) Chevr. 

 Acridoschema capricornis (1858) Thoms. 

 Acridoschema comexa (1894) Jord. 

 Acridoschema apicalis (1894) id. 

 Acridoschema atricollis spec. nov. 

 Acridoschema unifasciata (1858) Thoms. 

 Acridoschema varians (1894) Jord. 

 Acridoschema aherrans (1894) id. 



Acridoschema varians is so variable in the pattern of the elytra that it seems 

 to me probable that unifasciata is also only a form of the same species (of which 

 the name would be in this case unifasciata). 



Acridoschema aberrans differs remarkably from the other species in the antenna 

 not being tufted, in the spine of the prothora.x being truncate, and in the carinae of 

 the tibiae being vestigial. 



93. Discoceps griseus spec. nov. 



S ? . Very close to D.fasciatKs, differing only in the elytra being devoid of the 

 clayish band and having instead a few minute white spots before middle. Anterior 

 femur of S angulate above before middle as in fasciattts. 



Bab. Benito, French Congo. 



A series. 



94. Discoceps spildtus spec nov. 



cj?. Strncturally the same as the other two species, puncturation of elytra 

 coarser. Ujiperside glossy black, sjiotted with greyish white, the spots very 

 irregular and more or less confluent on the elytra ; those of the pronotum confluent, 

 less distinct, olivaceous grey.
