The coloration, form of tlie scutellum, &c. are tigbly distinctive 

 of this fine species. 



Bauystethus ater. B, late ellipticus, niger, supra opacus, subtus 

 Isevis, nitidus, capite pedibusque ferrugineis, nitentibus, prothorace 

 utrinque fortiter rotundato, tenuiter subrugoso-punctulato, margine 

 apicali pone oculos Iffite fulvo ciiiato ; elytris striato-punctatis, inter- 

 stitiis latis, convexis, impunctatis ; pygidio brevi, obtuso ; tibiis intus 

 Itete fulvo barbatis. Long. 6-9 lin.

This fine insect is at once distinguished from its only congener 

 J5. melanosovia, Bois., by its punctured prothorax. Lacordaire 

 says of ^. melanosoma that the penultimate joint of the tarsi is 

 alone spongy beneath ; but in my specimens of the present species 

 the three joints are so. In the ' Grenera ' (vi. 287), it appears to 

 me, there is some obscurity in the description of the sterna : in 

 this species at all events the mesosternum is triangular, the 

 angles a little rounded, and its apex received into a notch in the 

 raised subquadrangular portion of the prosternum behind the 

 anterior coxse. 



DiATHETES. 



(Calandringe.) 



Barystetho fere congruit, sed lobo scutellari prothoracis minus 

 producto ; tihii§ sulcatis vel lineatim punctatis ; metasterno 

 cum mesosterno continuato. 



In JBarystethus the scutellum is entirely covered by the scutel- 

 lar lobe, the metasternum is much swollen or enlarged anteriorly, 

 overlapping the posterior edge of the mesosternum, and the 

 tibiae are perfectly smooth ; in Diathetes the metasternum is of 

 the normal form, and the tibiae are coarsely grooved, the groove 

 formed either by a row of close-set punctures or by fewer 

 punctures connected by lines, the space between the grooves 

 constituting a smooth ridge. This character is, I think, an im-
