DescriptioDs of new genera and species 

 of Phytophagous Coleoptera 



ohtained l»y Herr Couradt in West-Africa (C'ameroons) 

 by ]?Iai*tiii Jac'oby. 



The Stettin Museum has submitted to me for examination the 

 Chrjsonielidae obtained by Herr Conradt at Barombi (Caniaroons) 

 West-Africa and I give here the descriptions of the genera and 

 species which seem to be new and to which I have added 

 u few oihers founded on species, contained in my collection 

 from other parts of Africa. The West-African fauna has evidentlj 

 little in common with other portions of that continent and of 

 which we only now begin graduallj to become acquainted 

 with the rieh insect fauna. If not stated olhcrwise the locahty 

 for all the described species in this paper is Barombi; tiiey are 

 contained in the collection of the Stettin Museum and that 

 of my own. 



Sagra Signoreti Thoms. 

 To judge by Thomsons insufllcient dcfcription, the speeimens 

 obtained by Conradt at Barombi must be referred to this species; 

 the foUowing is a more detailed description. Above dark green, 

 öubopaque, head and thorax impunctate, antennae comparatively 

 long, metallic green, the sixth and foUowing joints gradually 

 elongate; thorax longer than broad, the anterior angles thickened, 

 slightly ])roduccd outwards. the surface impunctate, opaque; 

 elytra very finely punctate-stiiate, the interstices slightly wrinkled 

 anteriorly ^^ ith a row of liiight green punctures near the lateral 

 margins; posterior femora rather short, ovate, the upper edge 

 strongly convex, the base with a short space of dense fulvous 

 pubescence at the inner surface, the apex wnth three teeth of 

 which the middle one is acute, the ajjical one broader and more
