Antennae longer than in E. marginatus, all the joints from the third, and the club, being longer. The thorax is not so broad, especially at the base, the hind angles in the male not being nearly so much produced, but still they are acute; its disk is more uneven, there being in the single male before m e an impressed pit on each side of the centre ; the elytra have the expanded margin more gradually widened, so that it is narrower at the shoulders than in E. marginatus. The four spots are larger in proportion, and placed nearer together than in that species, and they are more acuminate at the apex, and the middle of their disk is m u c h more acutely raised, the summit of this raised part being conical and nearer the two anterior spots than the corresponding part in E. marginatus. The front tibiae in the male are nearly straight, not strongly sinuous nor distorted as in E. marginatus, but a little compressed laterally with a short external groove at their apices (for the reception of the tarsi), but not grooved along their whole length. This insect has also some analogy with E. turritus ; but the larger yellow spots and the dark blue colour of the elytra, as well as the structure of the tibiae, will at once distinguish it. One specimen, a male, obtained by Mr. Whitehead. EUMORPHUS COSTATUS. Eumorphus costatus, Gorham, Endom. Rec. p. 34. Mas, tibiis anticis dente acuto valde distante in medio armatis ; tibiis intermediis et posticis mediocriter curvatis, his intus ciliatis. I believe a single male and female from Kina Balu to be identical with the species described by myself from two female specimens from Celebes. The male has the elytra shining, and with an indistinct violet tint, while the female is subopaque and is distinguished by a short keel on the elytra at their base near the scutellum. The yellow spots are large, and cause the species to recall E. quadrinotatus. The male has the hind angles of the thorax acutely produced, by which it is at once separated from E. quadrinotatus. EUMORPHUS GUERINI. Eumorphus guerini, Gorham, Endom. Rec. p. 33. Many specimens of this were obtained by Mr. Whitehead ; all 1 have yet seen are males. Hitherto only seen from the Malay peninsula. EUMORPHUS LUCIDUS, n. sp. (Plate IV. fig. 1.) Nigro-subviolaceus, nitidus; elytrisovatis, apice acwminatis, maculis duobus rotundatis aurantiacis nitidis, anteriore parum tumida ; thorace (femince) subopaco. Long. 9 millim. $ . Hab. Borneo, Kina Balu (Whitehead). It is difficult to compare this species with any other of the genus |
