'298 Mr. Charles J. Gahan on neir 



of the thu-d joint of the antenna?, by the much feebler 

 and sparser punctuation of the elytra, as well by the 

 more distinct raised lines on the latter. The remaining 

 two species of the genus — C. myor, Waterh., and C. 

 janns, Thorns. — have been described from female forms 

 only ; and their characters do not permit me to regard 

 the form just described as the male of either. 



Closterus seiraticornis, n. s. 



(7 . Fusco-ferrugineiis ; oculis magnis supra fere contigiiis, sl^btus 

 approximatis ; antennis corpore longioribus, articulis a tertio ad 

 decimum apice intus angulatim productis; prothorace crebre sub- 

 rugosoqiie pnnctato, pube sparsa fulvo-ferruginea obtecto, niar- 

 ginibus lateralibus angulis posticis siibrotmidatis ; elytris sub- 

 coriaceis, sparsini punctulatis, singulisque lineis elevatis quinque 

 vel sex ; pectore dense punctulato, et fulvo-ferrugineo pubescente ; 

 abdoniine breviter sparsimque pubescente et sparsim pimctulato ; 

 pedibus sat dense punctulatis, femoribus pubescentibus. Long. 

 33—35, lat. 11 mm. 



Rah. Madagascar. 



Eyes almost touching above, about a millimetre apart below. 

 Prothorax much broader than long, very closely and somewhat 

 rugosely punctured, clothed with a sparse and rather long tawny 

 red pubescence ; the lateral margins with the median tooth 

 distinct, the anterior angles scarcely prominent, the posterior 

 angles obtuse and almost rounded. Elytra somewhat coriaceous, 

 rather sparsely punctulate, and each with five or six raised longi- 

 tudinal lines which do not reach the apex and of which some are 

 almost obsolete. Body underneath, the abdomen excepted, densely 

 punctulate and clothed with a longish reddish tawny pubescence ; 

 abdomen sparsely punctulate, and with a short and very sparse 

 pubescence. The legs thickly enough punctulate, and the femora 

 with a rather long pubescence. Antennge about a fom-th longer 

 than the body, with the joints, from the third to the tenth, each 

 produced at its inner apical termination into an acutely angular 

 tooth. 



The present species is very distinct by the structure of 

 its antennpG, and ought to be, perhaps, on this account, 

 formed into a separate genus ; but as I find no other 

 character of sufficient importance by which to separate 

 it, I think it best to place it in the genus Closterus.
