cent than T. longipcnnis, Pasc, and is distinguished 

 further by the spatulate black spot on the head, the j)ale 

 transverse hnes on the elytra, the black spots at the 

 sides triangular in form, and the apices of the elytra 

 more rounded externally. 



Psathynis longipennis, n. s. 



Brunneo-ferrugineus, tenuiter fulvo-pubescens ; prothorace cylin- 

 drico, latitudine vix longiore, mimitissime et ci'ebre punctulatis ; 

 elytris elongatis, fulvo-brunneis, minute denseqiie punctulatis, 

 singulisque lineis duabus longitudinalibus elevatis, apicibus acunii- 

 nato-rotundatis ; femoribus compressis ; antennis longissimis, scapo 

 brevi, crasso, ad apicem cicatricoso, cicatrice transversina rugosa, 

 articulis a tertio sub-asperatis. Long. 19 mm. 



Hab. Madagascar. 



Head with the front rectangular and divided by a deep median 

 groove. Eyes with the lower lobes somewhat rounded, with the 

 upper lobes sub-approximate above. Prothorax scarcely longer 

 than broad, and not narrowed in front. Elytra very long, with two 

 feebly raised lines on the disk of each. Femora compressed, 

 narrowed to a knife-like edge on the upper side, and roimded 

 below ; with the anterior femora shorter and deeper, and concave 

 in front. Antennae very long, with the scape rather short and 

 thick, and provided with a transversely rugose cicatrice at the 

 apex; the cicatrice limited hj an incomplete but distinct carina, 

 external to which is a second shorter carina enclosing a small 

 depression. 



This species differs from P. asjyericorms, Chev., — the 

 type of the genus, and the only known species, — by its 

 shorter and somewhat differently shaped prothorax, by 

 its much longer elytra, and by its eyes more approximate 

 above. It agrees with it in the form of its head and 

 eyes, in the structure of its cotyloid cavities, and in 

 other important respects. The cicatrice of the scape 

 bears the closest resemblance in the two species, and is 

 of a kind quite peculiar to this genus, though no 

 mention of it is made by either Thomson or Lacordaire.
