Show 86 REV. H. S. GORHAM ON [Feb. 2, E. opaca, Crotch. The shortening of the third joint of the antennae and their bead-shaped appearance show this to be a strongly modified form. The femora are compressed and sinuous just as in Encaustes ; the middle tibiae have a tooth-like projection externally, just above the insertion of the tarsi, and are pubescent internally at their apices. The elytral epipleura are pitchy brown, but not noticeably so, and have obsolete transverse wrinkles. I have only seen four examples of this species, viz. those obtained by Mr. Whitehead. I cannot distinguish the sexes. ENDOMYCHID/E. AMPHISTERNUS ARMATUS, n. sp. (Plate IV. fig. 3.) Niger, opacus, obsolete varioloso-punctatus; thorace subquadrato, angulis anticis acutis, valde productis; elytris spinis duabus acutis ceneo-micantibus, una subhumerali, altera conoidea in medio, apice acute mucronato, tuberculisque duobus nigris nitidis, uno basali uno apicali ; femoribus clavatis, apicibus piceis. Long. 8 millim. Hab. Borneo, Kina Balu (Whitehead). Rather larger than A. spinicollis; and at once distinguished from both the described species of spinous Amphisterni by the two black tubercles, the produced front angles of the thorax, which are like those of A. auriculatus but not reflexed, and by the fiery coppery or aeneous colour which is seen on the shining parts. The head is thickly punctured, rather shining, and the antennae have all the joints from the third to the eighth elongate, the third longer than the two following united ; the sides of the thorax are slightly angu-late in the middle and narrow a little to the base ; the disk is quite opaque, with coarse confluent large punctures. Of the elytra the anterior tubercle has a pitchy tint, the humeral angle is reflexed and smooth, as is the basal margin ; the first lateral spine is a little below the shoulder, very long and acute, wide at its base, but compressed if viewed from behind, brassy black ; the middle spine more upright but still divaricating, conoidal at its base; both spines punctured at their base, as the elytra are. The posterior tubercle is bluish black and smooth; the apical production of the elytra is external to and independent of the sutural angle, which is itself quite distinct-it is in fact part of the margin itself, the epipleural fold being continued along it as a groove. The legs are brassy black, the club of the femora distinctly pitchy. Several specimens of this interesting new species were obtained by Mr. Whitehead. EUMORPHUS TUMESCENS, n. sp. (Plate IV. fig. 4.) E. marginati statura et similitudine ; niger, elytris nigro-cceruleis, late (humeris minus) marginatis, apicibus subacutis, maculis quatuor magnis aurantiacis. Long. 17, lat. 13 millim. 3. Mas, elytris in medio conjunctim alte et acute elevatis, pro-thoracis angulis posticis acutis, haud longe productis; tibiis |
