198 Longicornia Malayaiia. 



gradatim atteniiata et declivia, apicibus rotundatis. Pedes 



breves ; tarsi triangulares, articulo ultimo praecedentibus 



haud longiore. 



Except that the antennae are linear beyond the basal joints 



there is very little to distinguish this genus from Sijhia; the form

before me altogether a different character from any other in this

Gemylus albipictus. (PI. IX. fig. 1.) 

 G. niger, setulosus, maculis paucis niveo-pubescentibus ornatiis. 

 Hah.— Moriy. 



Deep black, somewhat glossy, with scattered setulose hairs, and 

 pure white pubescent spots or lines ; head irregularly and sparsely 

 punctured, a white spot below and another behind each eye ; pro- 

 thorax convex, rather narrower anteriorly, somewhat sparingly 

 pimctured, an oblique white stripe on each side ; scutellum small ; 

 elytra very convex, the sides nearly parallel for about two-thirds 

 of their length, then suddenly contracting, and each ending in a 

 rounded apex, irregularly punctured at the base, a small round white 

 spot before the middle, a short oblique line posteriorly and nearer 

 the apex a longitudinal one, both also white ; body beneath black ; 

 legs black, more or less striped with white, especially the tibiae and 

 intermediate and posterior femora ; antennae black, fuliginous

Sybra. 

 Caput antice subquadratum ; tuberibus antenniferis validis, 

 divergentibus, basi approximatis, Oculi prominuli, late 

 emarginati, supra approxiinati vel subapproximati. An- 

 tennce generaliter corpore vix longiores, graciles, setaceae, 

 subfimbriataa ; scapo brevi, ovato vel subcylindrico ; arti- 

 culis tertio et quarto multo longioribus et curvatis ; caetcris 

 brevioribus. Prothorax capite latior, lateribus rotundatis, 

 basi quam apice generaliter latior. Elytra subelongata, sub- 

 depressa, prothorace latiora, apicibus acutis vel apiculatis, 

 rarissime rotundatis. Pedes breves, aequales ; ni^sotibice

 generaliter longitudine aequales; coxes anticae et intermediae 

 mediocres, subdistantes. Pro- et meso-slerna declivia. 

 The general outhne of the species of this genus is different 

 from Ropica, being more elongate and I'usiform and very decidedly
