40 Mr. D. Sharp's Contributions to the 



tinQ;nislics it readily from its allies, viz., E. scvljdUis and 

 tlie species o1l Fahu/ria and Autalia. 



It may not be amiss to remark here, that although 

 1\I. Key, in the recently published parts of the " llistoire 

 Naturelle des Colcopteres de France," has placed the two 

 g^enera Autalia and Falcujria in different primary divisions 

 of" the Aleocharidce, still the two genera are really allied, 

 as the Eudera sculptilis and cava undoubtedly indicate. 



1. Eudera cava, n. sp. Hufescens, antennis'basi excepto, 

 capite, elytris, pectoi'eque obscurioribus ; thorace elytris- 

 que dense subtilissime punctatis, abdomine fere impunctato, 

 segmentis 2 — 4 basi ])rofunde transversim impressis; 

 thorace fortiter transverso, anterius obsolete impresso, basi 

 transversim bifbveolato. Long. corp. 1^ lin. 



Antennse short and stout, the basal joints reddish, the 

 others obscure in colour ; 3rd joint stout, a little shorter 

 than 2nd ; joints 4 — 10 similar to one another in length, 

 and each distinctly broader than its ])redecessor, the 4th 

 not so long as broad, the 10th strongly transverse; lltli 

 joint pointed, as broad as, and more than tw4ce as long as 

 loth. Head nearly black, short and broad, Avith a narrow 

 and remarkably abrupt neck, with a transverse impression 

 in front at the insertion of the antenna?, the surface very 

 finely, scarcely visibly, piuicturcd. Thorax obscure red- 

 dish, bi'oadcr than the head, but narrower than the elytra, 

 strongly transverse, the front angles rounded and de- 

 pressed, the hind ones rectangular ; on the middle, in 

 front, is a small indistinct impression, and in the middle, 

 in front of the base, is a kind of transverse imjn-essed 

 line, which is interru])tcd in the middle, and in certain 

 lights apjx'ars to consist on each side of two or three 

 very minute foveai placed extremely close to one another; 

 the surface is very finely and closely pimcturcd and 

 pubescent. Elytra short and broad, longer than the 

 thorax, the suture depressed at the base behind the 

 scutellum ; their colour obscure castaneous, their pimc- 

 tuation very fine, and not so dense as that of the 

 thorax. Hind l)()dv bi'oad, above sluTiing and flat; the 

 2nd, o\\\ and 4tli segments each with a})eculiar large deej) 

 transverse impression at the base ; at each front angle of 

 these impressions there is a kind of tubercle or projection. 

 Legs rather short ; middle co.\a> Avidely se]iarated. 



Parti ; eight individuals taken two or three years ago ; 

 I notice no indications of sexual distinctions among them.
