the otlier near the margin, I'eddish-fnlvous, these stripes are 

 united at the apex but do not extend to that portion of the elytra ; 

 under side ancl legs pale flavous. 



Hah. Brazih 



Of this large species three specimens are contained in my 

 collection. Amongst the longitudinally banded species desciibed 

 by von Harold in the Berl. ent. Zeit. 1881, there is none which can 

 be compared in size with this species, and all similarly coloured 

 forms have but one elytral stripe instead of two. 0. tceniolata 

 Har. has the eyes widely separated, a small thorax, and narrow 

 elytral epipleurte, and is much smallei'. 



Oedioxychis adjuxcta, sp. n. (Plate XY. fig. 12.) 



Black ; thorax impunctate, the margins flavous ; elytra im- 

 punctate, a subsutural vitta, the lateral margins, and a short 

 transverse band near the apex, connecting the stripes, flavous. 



Length 5g millim. 



Head broad, black, closely and strongly punctured in front of 

 the eyes, the latter small, very widely sepaiuted ; antennae veiy 

 short, the joints monilifoi'm ; thorax twice as broad as long, the 

 lateral margins strongly thickened, narrowly sulcate in front, the 

 anterior angles thickened, slightly produced, the disc impunctate, 

 black, all the margins narrowly flavous ; scutellum black ; elytra 

 without any perceptible punctuation, black, with the lateral 

 margins and a nai-row longitudinal stripe at the disc flavous ; this 

 stripe extends fi-om the middle of the base to the apex and 

 approaches slightly the sutuie below the middle, near the apex it 

 is connected with the flavous margin by another oblique ti^ansverse 

 thin stripe ; below and the legs black. 



Hah. Bolivia. 



Amongst the species with pale longitudinal stripes, the present 

 one seems most nearly allied to 0. haagi Har. in colour and 

 pattern, but diflfers in the entirely impunctate thorax and 

 elytra. 



Oedioxychis donckieri, sp. n. 



Elongate and parallel, the head fulvous ; antennae and breast 

 more or less black ; thorax flavous, impunctate ; elytra finely 

 punctured, obscure flavous, a sutural and a discoidal longitudinal 

 band black ; legs dark fulvous. 



Length 7 millim. 



Head lugosely punctured above the eyes, fulvous ; frontal 

 elevations strongly raised, broadly trigonate ; clypevis short and 

 broadly convex between the antenna? ; the latter robust, extending 

 to the middle of the elytra, black, the basal two joints piceous, 

 thii-d and fourth equal, the tei-minal joints more elongate ; thorax 

 rather more than twice as broad as long, not or scarcely narrowed 

 in front, the sides rounded, with a well-marked sulcus, the 

 anterior angles acute bvxt not produced, the disc ti-ansversely 

 grooved near the base, impunctate, flavous, i-ather opaque
