96 MR. M. JACOBY ON THE [Feb. 1, 



joint of the posterior tarsi rather longer than the two following 

 joints together ; claws bifid ; prosternum longer than broad, very 

 distinct ; mesosternum transversely subquadrate. 



The insect for which I am obliged to establish the present genus 

 has quite the appeaiance of a small species of Typophorus amongst 

 the Eumolpiiise. From any other genus of the present family, 

 especially from Munobia, Jac, Philogeus may be distinguished by the 

 dilated and flattened posterior tibiae in connection with the thoracic 

 groove and tiie dilated antennae, as well as by the bifid claws, 

 which is a character of rare occurrence amongst the Halticinse. 



Philogeus fulvipennis, sp. nov. 



Fulvous ; head, antennae, thorax and the legs black ; thorax 

 impunctate ; elytra very finely puactate-striate, fulvous. 



Length \\ line. 



Head impunctate, the frontal tubercles obsolete ; the carina 

 acutely raised ; antennae closely approached, nearly as long as the 

 body, the third and fourth joints equal, slightly longer than the 

 second, which is thickened, the sixth to the tenth joints gradu- 

 ally and distinctly widened, pubescent, the terminal one of usual 

 size, often fulvous. Thorax about one half broader than long, the 

 sides straight, the posterior margin slightly and broadly rounded, 

 the anterior angles forming an obtuse tooth before the middle ; the 

 surface scarcely visibly punctured, with an obsolete sinuate transverse 

 groove near the base extending some way upwards at the sides ; 

 scutellum rather broad, its apex rounded. Elytra extremely finely 

 and rather distantly punctate-striate, their apices rounded. 



Dikoya. 



Amphimeloides (gen. nov. Halticinorum). 



Subovate, convex. Antennae separated, inserted immediately 

 below the eyes, short, their apical joints widened. Thorax trans- 

 verse, the sides angulate before the middle. Elytra irregularly 

 punctured. Posterior femora strongly incrassate, their tibiae dilated 

 and slightly longitudinally sulcate near the apices, the latter armed 

 with a long spine. Claws appendiculate. Prosternum very narrow 

 but distinct. Anterior coxiil cavities open. 



From all other genera of Halticidae with the exception of Atnphi- 

 mela the present genus differs by the broad space dividing the 

 insertion of the antennae, while the open coxal cavities will distin- 

 guish the genus from Amphimela proper. 



Amphimeloides dorsalis, sp. nov. 



Fulvous ; the apical joints of the antennae, the posterior femora, 

 and the breast piceous or black ; thorax scarcely visibly, elytra 

 more distinctly and closely punctured, each elytron with a broad 

 longitudinal black band, abbreviated posteriorly. 

 ■ Length 1 line. 



Head impunctate, without transverse groove or frontal elevations ; 

 the cly pens not separated from the face, which forms a plane surface;
