5. Colaspoides iridipennis, sp. n. — Below piceous or blackish, 

 the antennae, labrum and the tarsi more or less fulvous, thorax 

 very finely punctured, cupreous, elytra very closely and strongly 

 punctate - striate , variously coloured in metallic longitudinal 

 stripes. 



Length 2 lines. 



Head 'very sparingly and finely punctured, of metallic green 

 or cupreous colour, the clypeus strongly punctured, antennae 

 fulvous, the apical joints more or less fuscous, the third joint 

 longer than the fourth, as long as the fifth joint, terminal joints 

 slightly thickened, thorax more than twice as broad as long, 

 the sides rounded, narrowly margined, the surface closely and 

 finely punctured, metallic cupreous or green with darker shades, 

 elytra without basal depression, strongly and closely punctured 

 in rows, the interstices at the sides and near the apex, costate, 

 the disc reddish cupreous, the suture and the sides metallic green 

 or blue, underside and legs piceous, tarsi obscure fulvous. 



Amongst the Eastern species of this genus, the present one 

 seems more nearly allied to C. insignis, Baly, but differs in 

 having the thorax more finely punctured but the elytral punc- 

 tuation much stronger and the interstices at the sides convex, 

 also in the handsome iridescent colour of the elytra, which 

 however varies in the two specimens before me and is arranged 

 in longitudinal stripes of purplish and green or blue ; in one 

 specimen the fulvous colour of the antennae is confined to the 

 lower five joints. 



6. Colaspoides apicicornis, Jac. — A specimen from Si-Oban 

 and one from Sipora agree in everything with the type from 

 Sumatra, except in the very sparingly punctured thorax, these 

 specimens seem to be females in which the elytra have also 

 more numerous longitudinal costae than in the other sex ; the 

 species may be known from others from the Malayan regions 

 in the fulvous antennae, which have only the last two joints 

 dark, and in the geminately punctured and costate elytra. 



7. Corynodes mentaweiensis , sp. n. — Below dark aeneous, 

 above metallic cupreous or purplish, basal joints of the antennae
