the other near the margin, reddish-fulvous, these stripes are 
united at the apex but do not extend to that portion of the elytra ; 
under side and legs pale flavous. 
fab. Brazil. 
Of this large species three specimens are contained in my 
collection. Amongst the longitudinally banded species described 
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. O. teniolata 
Har. has the eyes widely separated, a small thorax, and narrow 
elytral epipleure, and is much smaller, 
OEDIONYCHIS ADJUNCTA, sp. n. (Plate XV. 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 53 millim. 
Head broad, black, closely and strongly punctured in front of 
the eyes, the latter small, very widely separated; antennze very 
short, the joints moniliform ; 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 narrow longitudinal stripe at the disc flavous; this 
stripe extends from the middle of the base to the apex and 
approaches slightly. the suture below the middle, near the apex it 
is connected with the flavous margin by another oblique transverse 
thin stripe ; below and the legs black. 
Hab. Bolivia. 
Amongst the species with pale longitudinal stripes, the present 
one seems most nearly allied to O. haagi Har. im colour and 
pattern, but differs in the entirely impunctate thorax and 
elytra. 
OEDIONYCHIS DONCKIERI, sp. Nn. 
Elongate and parallel, the head fulvous; antennz 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 rugosely punctured above the eyes, fulvous; frontal 
elevations strongly raised, broadly trigonate ; clypeus short and 
broadly convex between the antenne ; the latter robust, extending 
to the middle of the elytra, black, the basal two joints piceous, 
third and fourth equal, the terminal 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 but not produced, the disc transversely 
grooved near the base, impunctate, flavous, rather opaque
