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. (PI. XXVIII. fig. 5.) 



G. nigro-purpurea, nitida ; prothorace crebre punctato, in medio 

 bituberculato ; elytris grosse punctatis, lateribus cyaneo mi- 

 cant ibus ; pedibus flavis ; tarsis infuscatis. 



Blackish purple, shining, the pubescence nearly obsolete ; head 

 narrow between the eyes, which are nearly contiguous above ; pro- 

 thorax oblong, gradually widening towards the base, the sides straight, 

 the disk bituberculate, closely and coarsely punctxired; scutellum 

 narrowly triangular ; elytra coarsely punctured, elongate, gradually 

 tapering from the base, the shoulders acutely 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 approxi- 

 mate 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.

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 riifo-luteis, immacidatis ; antennis nigris. 



Reddish luteous, partially pubescent ; head slightly punctured ; 

 prothorax equal in length and breadth, rounded at the sides ante- 

 riorly, 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
