224 MB. M. JACOBY ON PHYTOPHAGOUS COLEOPTEBA [Mar. 6, 



new genus of Eumolpide under tliis name from the West Coast of 

 Africa. In reading carefully his descriptions of the two species he 

 describes, I can come to no other conclusion than that the supposed 

 new genus is simply a Colasposoma, and his species D. passeti and 

 D. varicolor identical with Colasposoma pradieri Lefev. and G. fair- 

 mairei Lefev. respectively. M. Fairmaire compares his genus with 

 Sybriacus, to which the species mentioned above bear some superficial 

 resemblance ; but as the author makes no mention of the principal 

 characters of his genus, that is the shape of the anterior thoracic 

 episternum and the structure of the tibia? or claws, one cannot even 

 tell to which section Dasychlorvs may belong. I may be wrong in 

 my surmise regarding the present genus. In the descriptions of 

 Fairmaire of his two species there is, however, absolutely nothing 

 to distinguish it from Colasposoma, and it is certainly remarkable 

 that when describing a new genus of one of the most difficult 

 sections of the Phytophaga an experienced author should not even 

 mention the most important characters without which every clue 

 to its proper place is lost. Colasposoma pradieri (the largest 

 species of the genus) and C. fairmairei have both been described 

 by Lefevre as far back as 1877, and are well-known West African 

 species. 



Macetes clypeata, sp. n. 



Obscure cupreous, clothed with white and fulvous pubescence, 

 antennae and legs dark fulvous ; clypeus deeply emarginate ; head 

 and thorax very finely and closely punctured, metallic greenish ; 

 elytra of the same colour and sculpture, finely pubescent. 



Length 7 millim. 



Of broadly ovate, subquadrate shape : of a dark greenish-asneous 

 colour above, and clothed with lougish white and brown pubes- 

 cence ; the head closely and finely punctured, with a central groove ; 

 the clypeus very deeply and subtriangularly emarginate ; the 

 labriun cupreous, the palpi fulvous ; the antennae robust, entirely 

 fulvous, the basal joint cupreous above ; thorax nearly twice 

 as broad as long, subcylindrical, extremely closely and rather 

 finely punctured and pubescent ; scutellum broader than long, sub- 

 pentagonal, finely punctured and pubescent ; elytra much wider at 

 the base than the thorax, strongly narrowed posteriorly, depressed, 

 with another very feeble depression below the base ; below cupreous, 

 the femora fulvous with metallic gloss, clothed with dense white 

 pubescence ; the tibiae and tarsi more or less fulvous, the anterior 

 and posterior femora with a stout tooth, the others unarmed. 



Hub. Dunbrody, Port Elizabeth, S. Africa (Rev. J. O'Neil). 



Of this species I received a single specimen from the Rev. J. 

 O'Neil : it is perhaps nearest allied to M. albicans Chap. The species 

 is well distinguished by the deeply emarginate clypeus, the fine and 

 close punctation of its upper surface, and the colour of the pubes- 

 cence, which is white and brown above, but purely white only 

 below. Chapuis's species is unrecognizable, his description being 

 too brief.
