394 Mr. G. C. Champion on the Tenebrionde 
Omolipus cyanetpennis, n. sp. (Plate VIII., fig. 12, 3.) 
Moderately elongate, obovate, black, the elytra cyaneous or 
cyanco-violaceous, the entire upper surface subopaque. Head very 
minutely and sparsely punctured, the epistoma separated from the 
front by a fine impressed line, the eyes small ; antennz black, about 
reaching the base of the prothorax, thickening outwardly, the 
penultimate joints transverse, the apical one twice as long as the 
tenth ; prothorax broader than long, moderately convex, very finely 
margined at the sides, more distinctly so at the base, the sides 
rounded anteriorly, obliquely converging behind, and feebly sinuate 
just before the base, the hind angles distinct, the surface still more 
minutely and more sparsely punctured than that of the head (the 
punctures only visible under a strong lens) ; elytra about twice as 
long as the prothorax, and a little wider than it at the base, sharply 
margined at the sides and with the humeri rather prominent, 
widest about the middle and then rapidly narrowing to the apex, 
punctate-striate—the striz shallow, the punctures oblong in shape, 
not very coarse, and rather closely placed, and becoming finer 
towards the apex,—the interstices smooth and slightly convex ; be- 
neath dull pitchy-black, the two basal segments of the abdomen 
with a faint cyaneous lustre, the apical two or three segments 
slightly shining, the venter sparsely and very minutely punctured ; 
the prosternum canaliculate on either side, and declivous behind, 
the apex conically raised ; legs black, shining ; the anterior tarsi 
slightly dilated in the male. Length 54—84, breadth 2}—3} mm, 
(d 2). 
Hab. N. W. Australia—Baudin Island. 
This beautiful species was found in some numbers by 
Mr. Walker, under fragments of ironstone on the summit 
of the island, at an elevation of about 250 feet, in 
company with Metyche cxrulea. ‘The island upon which 
it occurred was named by the officers of H.M.S. “ Pen- 
guin,”’ during their surveying expedition to the coast of 
N. W. Australia, O. cyaneus, Pasc., is an allied form.
