ing in the sand, generally above, but often below, high-water 

 mark." Scymena differs inter alia from Pkaleria in its deeply 

 cmarginate clypeus. As the genera of the Trachyscelinai to 

 wliich it belongs 'have been much increased since M. Lacor- 

 daire's volume on the Heteromera was published, the follow- 

 ing table may be useful : — 



Antennfe eleven-jointed. 



Antennas longer tlian the bead. 



Prothorax closely applied to tlie elytra. 



Elytra ciliated at the margins Ecripsis, Paso, 



Elytra not ciliated at the margins Phaleria, Latr. 



I'rothorax not closely applied to the elytra .... Ilyocis, Pasc. 

 AntennfB shorter than the head. 

 Anterior tarsi retractile. 



Intermediate and posterior tarsi elongate, fili- 

 form Isarida, Pasc. 



Intermediate and posterior tarsi short, stont. . Ammobius, Gn^r. 

 Anterior tarsi not retractile. 



Antennfe with an abrupt three-jointed club . . C/zo'/Wes, White. 

 Antennaj gradually stouter outwards. 



Ch'peus deeph' emarginate Scymena, Pasc. 



Clypeus entire anteiiorly. 



Last tarsal joint as long as the rest toge- 

 ther AmmidiKm, Er. 



Last tarsal joint shorter than the rest 

 together. 



Posterior tarsi filiform, elongate Emypsara, Pasc. 



Posterior tarsi short, stout. 



Last joint of maxillarj' palpi seciui- 



form Sphcin/eris, Pasc. 



Last joint of maxillary palpi fusiform Aiieniia*, Casteln. 

 Antennae ten-jointed Trachi/scelisf, Latr. 



ByrsaxX saccharatus. 



B. oblongo-quadratus, iudumento albescente tectus ; prothorace 

 iitrinque autice explanato, postice eroso, disco supra valde gibboso 

 producto ; elj-tris grosse tuberculatis.

 Boletus) .

* This genus, founded on an African (Senegal) insect, I have not seen ; 

 its place here may be somewhat doubtful. M. Lacordaire unites it, erro- 

 neously, with Ammidium (Gen. v. p. 725). A rare European insect (^A. 

 sardoci) is referred to it. 



t M. Duval is the only author who has given the coiTect number of 

 antenual joints in this genus (Gen. Col. d'Eur. iii. p. 288). In reference 

 to his figure (pi. 71. fig. 352 6), I have failed to detect the moniliform 

 structure of the club, and the basal joint is much larger and curved 

 almost at a right angle. It must be recollected, however, that the whole 

 antenna is not larger than the point of a fine needle.
