310 Longicornia Malayana. 



head and prothorax impiinctate ; scutellum with a yellowish pu- 

 bescence ; elytra irregularly punctured at the base, the punctures 

 assuming a more linear arrangement near the suture, the apex of 

 each elytron drawn out into a small angle; antennae pale reddish- 

 testaceous, the apices of the joints brown. 

 Length 5 lines. 



Orsidis froletarius. 

 Monohammus proletarius, Pascoe, Trans. Ent. Soc. ser. 2, iv. 246. 



O. fuscus, subtiliter cinereo-pubescens ; capite prothoraceque 

 impunctatis ; elytris sub-angustatis, sub- seriatim punctatis, 

 apicibus sub-angulatis ; femoribus anticis valde incrassatis. 



Hab. — Macassar. 



Dark brown, with a very delicate close ashy pubescence ; head 

 and prothorax impunctate, the latter less transverse than in 0. in- 

 comptus, and having a very slight longitudinal median ridge ; 

 scutellum greyish ; elytra rather narrow, subseriate-punctate, the 

 apices sub-angular ; more sparingly pubescent beneath and on 

 the legs ; anterior femora very thick ; antennae reddish-brown, pu- 

 bescent. 



Length C lines. 



This species did not occur in Mr. Wallace's own collection ; 

 my original specimen serves for the above description, and this, as 

 mentioned loc. cit., has the eighth joint of its antennae remarkably 

 thickened ; whether this is its normal character seems doubtful. 



PSECTROCERA. 



Psectrocera, Pascoe, Journ. of Ent. i. 345. 

 Caput exsertum, antice sub-transversum, convexum ; tuberibus 

 antenniferis valde divergentibus. Oculi mediocrcs, normales. 

 Antennce corpore longiores ; scapo pyriforme, apice cicatri- 

 coso ; articulo tertio scapo duplo longiori ; caeteris gradatim 

 brevioribus, tribus ultimis aequalibus exceptis ; tertio, quarto 

 et quinto apice phimosis. Po/yji mediocres. Prothorax e\on- 

 gatus, cylindricus, inermis. £■/////■« breviuscula, ovata, supra 

 sub depressa, basi granulato-cristata, apicibus rotuiulatis. 

 Pedes mediocres, antici (^) multo longiores; femora in- 

 crassata ; tibice anticae sub-curvatae, apice intus dentatae, 

 intermediae emarginatae ; tarsi ut in Himantocera. Prosterniim 

 simplex. Mesosternum sub-dentatum. 

 Nearly allied to Gnoma, but differentiated by its cylindrical pro- 

 thorax, pyriform scape, and plumose antennae. Between this
