228 MB. M. JACOHY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, 



Nab. Cameroons. 



Allied to C. raffrayi Lefev. but differing in the spotted head and 

 thorax and the black not fulvous underside. I have received a 

 single specimen from Herr Bang-Haas. 



PSEUDOSIAGRUS AFRICANUS, Sp. 11. 



Piceous, the sides of the thorax and the legs fulvous ; thorax 

 closely punctured ; elytra fulvous, finely punctate-striate, the 

 punctures obsolete posteriorly, each with an oblique band at the 

 shoulders and another below the middle, black ; the anterior 

 femora dilated into a strong tooth, the posterior ones with a 

 smaller one. 



Length 5| millim. 



Head finely rugose, obscure fulvous, the middle piceous ; the eyes 

 extremely large, closely approached ; clypeus not separated from 

 the face, strongly rugose ; antennae piceous, the lower four joints 

 fulvous, the third joint one half longer than the second, terminal 

 joints distinctly thickened ; thorax transverse, of equal width, the 

 sides strongly rounded, with a narrow margin, the posterior angles 

 dentiform, the disc closely impressed with strong, round punctures, 

 piceous with a slight metallic gloss, the sides, in shape of a 

 posteriorly narrowed band, fulvous ; scutellum triangular ; elytra 

 regularly punctate-striate, the punctures entirely obsolete at the 

 apex, the interstices flat and impunctate ; a short black oblique 

 band extends from the shoulders towards the suture and another 

 of similar shape is placed below the middle, there is also an indi- 

 cation of a black short stripe near the lateral margins ; legs 

 fulvous, the four posterior tibiae carinate, emarginate at the apex, 

 claws bifid ; anterior margin of the thoracic episternum convex ; 

 anterior femora with a very strong triangular tooth. 



Hah. Matabeleland, near Tati. 



This genus was established by Fairmaire on a species from 

 Madagascar. There seems to be scarcely any difference between 

 the present genus and Tricliona Lefev., which was published at the 

 same time and in the same French "Annals " ; but which of the 

 genera appeared first in print I am unable to say. Tricliona was 

 up to the present only known from India and Sumatra, but both 

 genera agree in most details, especially in the enormously dilated 

 anterior femora. I think, however, that the shape of the thorax is 

 different in Pseudosyagrus, the latter being not at all narrowed in 

 front and having strongly rounded sides. There is a single 

 specimen of the present insect contained in my collection, well 

 distinguished by its coloration. 



Odontionopa c^rulea, sp. n. 



Metallic dark blue, antennae and tarsi black, thorax extremely 

 finely punctured; elytra convex and cylindrical, rather strongly 

 punctured in closely arranged longitudinal rows, the interstices 

 Avith a few minute punctures, the posterior femora with a distinct 

 tooth.
