14 Longicornia Malayana. 



Polmeta spinosida. (PI. I. fig. 4.) 

 Ostedes spinosida, Pascoe, Joiirn. of Entora. i, 62, 



P. grisescens, fusco-variegata ; elytris basin versus spinosis, 

 spina incurva. 



Hab. — Batcliian, Amboyna, Morty, Dorey. 



Finely pubescent, greyish varied with brown, the two principal 

 patches of this colour being on the sides of the elytra. Head 

 somewhat wider than the anterior margin of the prothorax, the 

 latter a little longer than wide, with two nearly obsolete tubercles 

 in front, anteriorly and posteriorly transversely sulcated ; scu- 

 tellum rounded behind ; elytra narrow, the basal half sparingly 

 punctured, a prominent, strongly-recurved spine on each towards 

 but at some distance from the base, a few minute spines also at 

 the base and sides ; legs dark brown, more or less of the femora 

 and basal half of the tibias reddish ; body beneath reddish-brown; 

 antennae more than half as long again as the body, reddish varied 

 with brown. 



Length 4 lines. 



A specimen from Ceram, much larger than the others, has also 

 a somewhat broader prothorax. It may possibly be distinct. 



Polimeta simplex. 



P. grisescens, fusco-variegata ; elytris muticis. 



Hah. — Batchian, Ceram, Gilolo, Morty, Bouru, Dorey, Saylee. 



Closely resembles the last, but there is no spine on the elytra, 

 which are also less attenuated towards the apex, the sides, in 

 other words, being more parallel ; the scutellum is slightly pointed, 

 and the anterior border of the prothorax is less strongly sulcated. 



Length 3| lines. 



Ostedes. 

 Ostedes, Pascoe, Trans. Ent. Soc, ser. 2, v. 43. 

 Caput exsertum, antice transversum, tuberibus antenniferis basi 

 contiguis. AntenncB corpore longiores, ciliatae, scapo sub- 

 fusiformi, articulo secundo breve, 3" 4"que aequalibus, 

 caeteris gradatim decrescentibus, Ocidi prominuli, supra 

 subapproximati. Prothorax maribus clongatus, fominis raulto 

 brevior, irregularis, utrinque fortiter angulatus. Elytra 

 angustata, basi cristata et latiora, apice oblique truncata. 

 Pedes postici subelongati, femoribus subclavatis. 

 This genus has not a very obvious afliinity with any of the 

 AcanthocininoB except the last, but the long basal joint of tlie
