444 MR. MARTIN JACOBY ON NEW SPECIES [ Noy. 28, 
by Clark, and formerly in the Baly collection. The colour of the 
elytral bands, their shape, and the more than usually convex and 
widened general shape of the insect, distinguish this species. 
Whether O. jaculus MIllig. is identical with this or some other 
similarly marked species I am unable to say, but Tliger’s 
description of the shape of the elytral bands does not agree with 
that of the insect before me. 
OEDIONYCHIS REGINA, sp. n. (Plate XIV. fig. 12.) 
Large and broad, black, the last two joints of the antenne pale 
yellow ; thorax impunctate, flavous, with a large black transverse 
band; elytra strongly and very closely punctured, metallic dark 
green; the lateral margins and a transverse band below the 
middle testaceous. 
Length 10 millim. 
Head bluish-black, impunctate, except near the eyes, the latter 
with a flavous spot near the inner margins, widely separated ; 
antenne slender, black, the last two joints pale flavous, third 
joint slightly shorter than the fourth ; thorax rather more than 
twice as broad as long, the sides broadly flattened, evenly rounded, 
the anterior angles thickened, very slightly produced outwards, 
the disc impunctate, black, the lateral and basal margins flavous ; 
scutellum black; elytra widened below the middle, closely and 
strongly rugose-punctate, metallic green, the lateral margins 
narrowly and a slightly wider transverse band, immediately below 
the middle, testaceous ; under side and legs black. 
Hab. Espirito Santo, Brazil. 
The black thoracie band which extends to the anterior margin, 
the colour of the antenne, and the strongly punctured elytra well 
distinguish this species from any other. 
OEDIONYCHIS DIFFICILIS, sp. n. (Clark, MS8.). 
Black, thorax flavous, impunctate ; elytra convex, widened 
posteriorly, closely and finely punctured, flavous, a broad trans- 
verse band at the base and another band below the middle, with 
the lateral and posterior margins rounded, metallic blue, both 
bands not extending to the margins. 
Length 6-9 millim. 
Head impunctate, black, two or three deep punctures are 
placed near the eyes, frontal tubercles trigonate, nearly connected ; 
antenne rather long, black, the base at their insertion flavous, 
third and fourth joints nearly equal; thorax twice as broad as 
long, the sides rounded anteriorly, the anterior angles produced 
into a small tooth, the disc impunctate, flavous or fulvous ; 
scutellum black; elytra widened towards the middle, convex, 
finely and closely punctured, flavous, with two transverse dark 
blue bands—the first at the base, of regular shape, with its 
posterior edge straight and not quite extending to the middle, 
the second band below the latter, its anterior margin straight, 
but the lateral and apical margins rounded, the last-named some-
