Cratogaster melas, Cast. 



The Baron de Chaudoir (Ann. Mus. Gen. Vol. VI., p. 574) 

 has stated that he has examined the original type of this inseci, 

 and found it to be identical with Feronia (Cratogaster) sulcata, 

 Blanch. It, therefore, appears to be by an oversight that the two 

 stand in Mr. Masters' Catalogue as distinct. 



Rhytisternus sulcatipes, sp.nov. 



Sat depressus ; niger ; antennis palpis tarsisque elongatis 

 gracilibus plus minus rufescentibus ; prothorace vix transverso, 

 postice utrinque bistriato, — striis haud in excavatione per- 

 spicua positis, lateribiis postice haud sinuatis ; elytris striis 

 5, 6, et 7-a plus minus obsoletis ; tarsis posticis extus sat fortiter 

 sulcatis. Long. 7 lines, lat. 2§ lines. 



A depressed parallel somewhat slender insect, having much the 

 build of the European Adelosia picimanus, Heer. The antennae 

 and tarsi are longer and much more slender than those of B. 

 liopleura, Chaud. ; the palpi also are more slender, otherwise the 

 head does not differ noticeably. The prothorax is scarcely a 

 quarter as wide again as it is long down the middle, its 

 base scarcely narrower than its front margin, which is slightly 

 coiacave, with anterior angles scarcely produced ; the sides are 

 moderately and rather evenly rounded, but so that the prothorax 

 is at its widest just in front of the middle (though less in front of 

 the middle than that of R. liopleii,ra) ; they are not at all sinuate 

 behind ; the bind angles are very obtuse, but not quite rounded, 

 and not in the least " subdentate " (as they are in R. liopleura, 

 Chaud.) ; the transverse impression on the front of the disc is 

 scarcely marked, the dorsal channel fairly strong but not very 

 nearly reaching either the base or the front margin ; there are 

 two well-defined sulci on either side behind, which are not placed 

 in an excavation, but are separated by a space continuous with 

 the general surface of the prothorax ; of these the inner one is
