Nine specimens in Mr. Fry's collection are certainly identical with what I described in 1873, but are better matured, and enable me to supplement that account by stating that while the thorax and body, and sometimes the head, are pitchy red but dark, the elytra vary from dark blue, almost black, to violaceous. A somewhat less matured specimen has the suture and margins of the elytra rufous. The insect seems to occur indifferently on the mountains and in the low country about Perak. CYMBACHUS FOBMOSUS, n. sp. (Plate XXXII. fig. 1.) Nlgro-vlridis; ore, antennis, palpls pedibusque nigris; elytris fiavis, humerls macula magna discoldall communi, alteraque marginali magis poster-lore, aplce, eplpleuris, sutura tenulter reglone circumscutellari ccerulels, creberrlme minute dlstlncte punctatls. Long. 6*75 millim. § - Hab. B U R M A , Ruby Mines (Dohertg). The punctation in this species is a little more distinct than in C.pulchellus, o*, so that that of the thorax is just visible ; in size and form it very closely resembles that insect, but diverges in the green colour of the body and in the blue markings of the elytra. The prothorax and femora have a blue tint; the humeral callus is decidedly more elevated, and is covered by the blue spot, which is wanting in C. pulchellus. The latter insect is very rare, having apparently always been obtained in single specimens ; the example in m y present collection is a male from Java. By comparison with this the single example of C.for-mosus, obtained by Mr. Doherty, is a female. The discovery of a second species of this scarce and beautiful genus is among the many most interesting features of Mr. Doherty's travels. EUMORPHUS WESTWOODI, Gorham, Endom. Recit. p. 35. B O R N E O , Banjarmassan (German Mission), Pengaron, Martapura (Doherty); P E R A K (Doherty). I have now seen a series of specimens of an insect which I can only refer to this. The males have (in addition to the toothed front tibias) the middle tibiae strongly sinuous, and with several minute denticulations on the inner side, while the females have nearly simple tibias, but are otherwise like the males. The examples (in m y own collection) from Martapura, S.E. Borneo, have the spots suffused, reaching quite to the margins and suture. The club of the antenna is very wide, and the joints connate or nearly so. E U C T E A N U S CRUCIGER, n. sp. (Plate X X X I I . fig. 10.)
