undersurface deep, their sides slightly wrinkled. Pro thorax 
strongly rounded, decidedly longer than wide, wider than head; a 
feeble impression at base, and a still feebler interrupted one at 
apex ; base narrowly margined and feebly sinuate. Elytra 
gradually dilating towards apex, each feebly separately rounded. 
Length to apex of elytra 3J, of abdomen 6 J; width l^mm. 
Hob. — Tarn worth. 
A very narrow species, in colour strongly resembling C. cyanop- 
terus, but the width of that species at once separates them. 
Carphurus alterniventris, Fairm., Mast. Cat. Sp. No. 3412. 
I have a pair (obtained in copula) of this species from the 
Tweed River. The male has the elytra concolorous, whilst in 
the female they are diluted with red along the base and basal 
margin; the head in the latter is without markings, while in the 
former there is a distinct black blotch connecting the eyes. 
Carphurus basiventris, n.sp. 
£. Elongate, shining, depressed. Head, basal joint of antennae 
and undersurface of two following, prothorax, extreme tip of 
femora, tibiae, and basal joint of tarsi, reddish- testaceous ; elytra 
very dark purple; abdomen with the basal segment, apex of second, 
apical, and base of penultimate, diluted with red. Above and 
the legs covered with long black hair, densest and shortest on 
elytra; sterna with very indistinct pubescence. Head rather 
densely, irregularly and minutely, prothorax sparsely and minutely 
punctate; elytra densely and strongly punctate, at the base less 
strongly than elsewhere; undersurface very indistinctly punctate. 
Head much longer than wide; eyes small, prominent; a broad 
and very shallow depression on each side between eyes; mandibles 
prominent; antennae scarcely passing base of prothorax, the joints 
flat, 1st slightly longer than 2nd-3rd combined, 2nd scarcely the 
length of 3rd, 3rd-10th subequal, 4th-10th serrate inwardly, 11th 
not one and a half times as long as 10th; corrugated at base, 
sides and undersurface; fovese small, open behind, the space behind 
them distinctly corrugated. Prothorax a trifle longer than wide,
