Show 1866.] MR. F. P. PASCOE O N T H E COLEOPTERA OF PENANG. 259 deeply emarginate than in the more typical forms of G. elegans. Viewed as one polychromatous species, it extends from India to New Guinea, but is apparently nowhere more common than in Malacca. GLENEA PORPHYRIO. (PL XXVIII. fig. 5.) G. nigro-purpurea, nitida ; prothorace crebre punctato, in medio bituberculato ; elytris grosse punctatis, lateribus cyaneo mi-cantibus ; pedibus flavis; tarsis infuscatis. Blackish purple, shining, the pubescence nearly obsolete ; head narrow between the eyes, which are nearly contiguous above ; prothorax oblong, gradually widening towards the base, the sides straight, the disk bituberculate, closely and coarsely punctured; scutellum narrowly triangular; elytra coarsely punctured, elongate, gradually tapering from the base, the shoulders acuteby prominent, the sides with a bluish tinge, apices slightly obliquely truncate with the outer angle produced; body beneath chalybeate blue, with a whitish pile on the sterna; legs yellow, the tarsi brownish, the posterior only partially so ; antennae purplish black. Length 12 lines. A very distinct species, with an unusually narrow head and approximate antennary tubers, at variance with the characters of the genus. The elytra have faint indications of a bluish pubescent spot on the centre of each, and also at the apex. GLENEA BLANDINA, Pascoe, Trans. Ent. Soc. ser. 2. iv. p. 259. Mr. Lamb's specimens rather depart from the typical form in having the sutural region pale greyish brown. In other respects, however, they agree. The species is distinguished by the first three joints of the antennae, underneath, being of a beautiful cobalt-blue. Another species, confined to a single example, has a similar coloration; ^ but the spots are white, not blue, the elytra more obliquely truncate at the apex, the form narrower, and the eighth and ninth joints of the antennae pure white. It is without doubt distinct. GLENEA RUFINA, Pascoe, Trans. Ent. Soc. ser. 2. iv. p. 259. One of the four species in the present collection that is found also in Burmah. It is a pale but clear reddish chestnut-colour, with greyish or greenish-grey elytra. GLENEA NEANTHES. (PL XXVIII. fig. 4.) G. rufo-lutea ; elytris castaneis, nitidis, niveo maculatis, regione suturali et lateribus rufo-luteis, immaculatis ; antennis nigris. Reddish luteous, partially pubescent; head slightly punctured ; prothorax equal in length and breadth, rounded at the sides anteriorly, vertically compressed behind, the disk with few punctures and two small round black spots ; scutellum scutiform ; elytra broad at the base, gradually narrowing posteriorly, a broad brown nearly glabrous stripe from the shoulder to the apex, limited externally by the carina, but shading off towards the suture, and having five snowy-white pubescent spots; body beneath pale ferruginous, with an |
