504 Longicornia Malayans. 



§ § § Protliorax not toothed at tLe sides. 

 Tetraommatus ocularis. 



T. linearis, toto testaceus ; prothorace oblongo, mutico. 



Eab. — Morty. 



Very narrow, and of nearly equal width throughout, 

 entirely testaceous, and finely punctured above ; upper 

 lobes of the eyes large and nearly contiguous on the 

 vertex ; protliorax very slightly rounded at the sides, no 

 vestige of a tooth ; apices of the elytra somewhat dehis- 

 cent, rounded ; femora compressed, their bases suddenly 

 narrowed, and a little curved, posterior tarsi with the 

 basal joint nearly twice as long as the three following 

 together. 



Length 2h lines. 



This delicate little species has the same style of femora 

 as the more typical forms, from which, notwithstanding 

 its peculiarly narrow outlines and mutic prothorax, it 

 cannot be generically separated. 



Hyphus. 

 Hyphus, Lacordaire, Gen. viii. 226. 



Capid porrectum, antice breve, verticale; tuberibus 



antenniferis validis, prominentibus, basi contiguis ; 



sutura clypeali profunde impressa. Oa<// supra valde 



emargiuati. AntemuH setacege, infra ciliatas, corpore 



longiores ; ,sraj30 breviusculo, cylindrico; articulo ter- 



tio sequentibus Ion gi ore. Protliorax transversus, 



convexus, utrinque rotundatus, vel subtuberculatus, 



disco ina3quali. Elytra elongata, postice sensim et 



leviter attenuata, apice rotundata, epipleuris verti- 



calibus. Pedes longiusculi ; femora compressa, ellip- 



tico-clavata ; tihice arcuatse, posticaj longiores ; tarsi 



postici articulo basali elongate. Coxa^. anticre approxi- 



matae. Prosternum compressum ; 'tutsosternum am- 



plum, declive. Ahdomen (c? ?) postice gradatim 



attenuatum, ( ? ?) cylindricum. 



M. Lacordaire has founded this genus on a somewhat 



remarkable insect in Count Mniszech's collection, which, 



from its cylindrical abdomen I should have been inclined 



to consider a female, if the learned Professor had not 



stated the contrary. At any rate, in a second species 



described below, the abdomen is very much narrowed at 



the apex, and this I have very little doubt is a male. 



The genus is at once distinguished from all others of its 



sub-family by its vertical epipleurae.
