Show 1890.] COLLECTED BY MR. BONNY. 641 belongs to it. The sharply margined subquadrate thorax, the dilated and excavate, broad penultimate joint of the tarsi, the sharply toothed claws, the posteriorly narrowed head, and the elongate, somewhat cylindrical shape distinguish Sterces from the other known genera of Cnodalonides. The genus is perhaps best placed between Camarimena and Acropteron. STERCES RESPLENDENS, sp. n. (Plate LVI. figg. 3, 6; 3 a, labium ; 3 6, maxilla and maxillary palpus ; 3 c, anterior tarsus.) Head and prothorax black, the latter with a slight violaceous lustre ; the scutellum black ; the elytra bright metallic green, this colour (in certain lights) changing to violaceous towards the suture and along the lateral margins ; shining. Head somewhat flattened, depressed in the middle between the eyes, finely, deeply, and rather closely punctured, the epistoma smoother ; antennae black, joints 6-10 broad, transverse, 6-8 subtriangular, 11 about one half longer than 10 ; prothorax as long as broad, subquadrate, narrowing a little in front and slightly sinuate at the sides behind, the hind angles acute and directed outwards, the disc broadly transversely depressed in the middle before the base and obsoletely canaliculate in front, the surface finely, irregularly, and rather sparsely punctured (the punctuation finer than that of the head), a longitudinal space down the middle impunctate ; scutellum smooth ; elytra very finely punctate-striate, the interstices quite flat and with very minute widely scattered punctures; beneath very shining,blackish-violaceous, very sparsely and minutely punctured, the first three ventral segments also with very fine shallow longitudinal rugae ; legs black, the femora broadly marked with reddish-testaceous beyond the middle (the apex and base alone black), the tibiae and tarsi thickly, the femora very sparsely, punctured, all the tibiae slightly dilated within at the apex and somewhet curved, the femora glabrous. Length 16-^, breadth 5 millim. ( 6 •) One example. NESIOTICUS, Westw. NESIOTICUS FLAVOPICTUS. (Plate LVI. fig. 4, var.) Nesioticus flavopictus, Westw. P. Z. S. 1842, p. 121 ; Trans. Z. S. iii. p. 227, t. 15. f. 13 ; Thorns. Arch. Ent. ii. p. 92, t. 3. f. 1. Numerous examples. These differ from the type in the shape of the transverse flavous basal fascia of the elytra, and they form a well-marked variety : the fascia extends inwards to a little nearer the suture and usually has a short additional ramus extending forwards from its point of termination. STRONGYLIUM, Kirby. STRONGYLIUM ATROVIOLACEUM, sp. n. (Plate LVI. fig. 5.) Elongate, parallel, opaque, bluish-black, the head in front and the elytra obscure violaceous. Head distinctly grooved between the |
