212 ON THE GENUS CEROBATES. 



antennae graciles , totius cor- 

 poris longitudine parce bre- 

 viores, articulis elongatis, cy- 

 lindricis, longe, finissime pi- 

 losis Jonthocerus Lac. 



The species of the genus Cerobates Schh. are of small 

 size , of graceful form and often closely allied to one another , 

 therefore the determination is not always easy. As I de- 

 scribe here some new species, I believe it useful to give 

 a table for the determination of all the species known at 

 present ^). 



I. Elytrorum angulus apicalis externus 

 rotundatus et marginatus. 

 A. Prothorax omnino laevis, dorso pla- 

 natus vel modice convexus. 

 a. Elytra juxta suturam basi vel usque 

 ad apicem tristriata, versus latera 

 laevius striata aut substriato-punc- 

 tulata, raro omnino laevia; stria 3^ 

 dorsali usque ad apicem prolongata, 

 interdum pone medium obsoletiore, 

 raro obliterata. 



b. Anteuuarum articulus apicalis 

 conspicue longior articulo prae- 

 cedente , subcylindricus , apice 

 acuminatus. 



c. Metarostrum et mesorostrum 

 sulcata , elytrorum striae im- 

 punctatae. 



1. Subnitidus; capite, protho- 

 race, elytrorum basi, regione 

 suturali fasciaque transversa 

 postmediana nigris vel ni- 



1) Cerobates aciculatus Walker from Ceylon (Ann. and Magaz. of Nat. Hist., 

 3rd ser. Ill, p. 263, 1859) is unknown to me and the description insullicient. 

 I believe this species does not belong to Cerobates.
