436 MR. MARTIN JACOBY ON NEW SPECIES [NoV. 28, 



Head piceous or black, tlie vertex coarsely punctured, the 

 clypeus flavous ; antennte black, the third and fourth joints very 

 nearly equal ; thorax strongly transvei'se, the sides strongly but 

 not broadly flattened, the lateral margins rounded in front, 

 anterior angles dentiform, the suiface impunctate, flavous, with a 

 very obsolete transverse sulcus near the base ; scutellum black ; 

 elytra finely and closely punctured, bluish black, the discoid al 

 flavous stripe of double the width of the similarly coloured 

 lateral margins and connected with the latter at the a,pex ; under 

 side and legs black ; elytral epipleurse with a very narrow inner 

 dai'k margin. 



Hah. Brazil. 



This banded species is more nearly allied to 0. figtirata Chev. 

 than to any other, and may be known by the dark head, antenna^, 

 and legs, the broad diseoidal elytral flavous stripe, which has 

 somewhat irregular outlines, and by the inner dark margin of the 

 elytral epipleuras. The species, if these details be kept in view, 

 cannot be mistaken for any of those of which v. Harold has given 

 an analytical table (Berlin, ent. Zeitschr. 1881). 



Oedionychis exclamationis, sp. n. (Plate XV. fig. 3.) 



Testaceous, the intermediate joints of the antennae black ; 

 thorax impunctate ; elytra minutely punctured, two elongate 

 spots at the base and a longitudinal stripe at the sides, strongly 

 thickened at the upper end, black. 



Length 7 millim. 



Head impunctate ; the eyes large, each as wide as the inter- 

 vening space ; carina short and convex, narrow ; antennae tes- 

 taceous, the sixth to the ninth joints blackish, third smaller than 

 the fourth joint ; thorax more than twice as broad as long, the 

 sides strongly rounded and broadly flattened, the anterior angles 

 produced into a small tooth, the surface impunctate ; elytra not 

 wider at the base than the thoi-ax, with narrow reflexed lateral 

 margins, extremely finely and closely punctured, testaceous, the 

 base with two black longitudinal short stripes, the sides near the 

 margins with another longer narrow black stripe, which ends 

 anteriorly rather abruptly in a club or knob directed towards 

 the suture ; under side and legs testaceous. 



Hob, Brazil. 



I know of only a single specimen of this ra,ther peculiarly 

 marked species, the exact locality of which is unknown to me. 



Oedionychis interrupto-vittata, sp. n. (Plate XY. fig. 6.) 



Testaceous, the head and the intermediate joints of the antennae 

 black ; thorax impunctate, the anterior angles mucronate ; elytra 

 finely punctured, testaceous, each elytron with two more or less 

 intei-rupted longitudinal black stripes ; the breast black. 



Length 6 millim. 



Of flattened shape; the head impunctate, black, deeply foveolate 

 between the eyes, the latter large, their diameter as wide as the
