180 MR. M. JACOBY ON NEW [Mar. 2, 



29. CEdionychis abbreviata, sp. nov. 



Broadly ovate. Fulvous ; elytra distinctly punctured, fulvous or 

 flavous, a broad transverse basal band and two others behind the 

 middle, none of them touching the lateral margins, violaceous blue. 



Var. The posterior bauds united into a large patch. 



Length 3|-4 lines. 



Hab. Amazons. 



Head with a few distinct punctures at the vertex and a deep fovea 

 in the middle ; antennae entirely fulvous or piceous, with the first 

 three joints fulvous. Thorax about three times as broad as long, its 

 sides broadly flattened, anterior angles produced into a blunt tooth, 

 surface minutely punctured ; scutellum fulvous. Elytra closely 

 punctate, longitudinally impressed within the humeral callus ; 

 surface rather convex, with three violaceous blue bands across the 

 disk, the two posterior ones of which are closely approached and 

 narrower than the basal one. Underside and legs fulvous. 



This species seems closely allied to bifasciata, Baly ; but the 

 antennae and apex of the posterior femora are described as black, 

 and only two elytral bands are mentioned. It may, however, turn out 

 to be a variety of Baly's species. 



Three specimens in my collection. 



30. CEdionychis MARGiNicoLLis, sp. nov. (PlateXVIII.fig.il.) 

 Oblong-ovate, convex. Black below (tarsi excepted), above vio- 

 laceous blue ; sides of the thorax and a narrow sutural and marginal 

 vitta of the elytra, united at the base and apex, flavous. 



Length 3 lines. 



Hab. Rio Janeiro. 



Head deeply punctured at the vertex, about as broad as long ; eyes 

 prominent ; antennae black, the two basal and the apical joints 

 fulvous. Thorax comparatively broad, sides flattened and evenly 

 rounded ; anterior angles acute, but not produced into a tooth ; 

 surface impunctate, black, lateral margins flavous. Elytra convex, 

 widened behind the middle, strongly punctured at the base, less so 

 towards the apex ; each elytron with a curved, narrow, longitudinal 

 vitta near the suture and the lateral margin flavous ; the sutural 

 vitta forms a continued line with the flavous thoracic margin, and 

 unites at the base and the apex with the lateral band, the space be- 

 tween the two bands being widest in the middle of the elytra; 

 epipleurae of the latter also flavous. Underside and legs black ; 

 extreme apex of the tibiae and the tarsi fulvous. 



Type in my collection. 



At first sight this species seems closely allied to cosmogramica, 

 Harold ; but the punctuation of the elytra and the coloration of the 

 legs and antennae distinguish it. 



3,1. CEdionychis sex-plagiata, sp. nov. (Plate XVIII, fig. 12.) 

 Oblong-ovate. Fulvous; above flavous; disk of thorax, the suture, 

 and three transverse bands on each elytron fulvous. 

 Length 3f lines.
