342 INSECTA. 



Galba, Lat. 



Mandibles terminating in a simple point ; maxillae unilobulate; 

 last joint of the palpi globular; the body almost cylindrical l). 



Eucnemis, Arh. 



Mandibles bifid; maxillae bilobate; last joint of the palpi nearly 

 securiform, and the body almost elliptical(2). 



At other times the antennas, occasionally clavate, are received, at 

 least partially, either into the longitudinal grooves of the lateral 

 borders of the presternum, or into fossulas situated under the pos- 

 terior angles of the thorax. The tarsi are frequently provided with 

 little palettes formed by the prolongation of the inferior pellets, or 

 the penultimate joint is bifid. 



Some, with filiform antennae, have the joints of the tarsi entire 

 and without palettes underneath; the anterior legs, when contracted, 

 are received into lateral cavities in the inferior surface of the thorax. 

 Such is the 



Adelocera, Lat.(3) 



Others, with antennae also of equal thickness throughout, have 

 the joints of the tarsi entire, but the inferior pellets prolonged or 

 projecting in the manner of little palettes or lobes. Their head is 

 exposed. They form the 



Lissomus, Dalm. Lissodes, Lat. Drapetes, Meg. Dej.(4) 



Others again have equally filiform antennae, but their second and 

 third joints are flattened, larger than the following ones, and are 



(1) I have seen three species, all from Brazil. One of them has many points of 

 resemblance to the Melasis tuberculata, Dalman Anal. Entom. The maxillse ter- 

 minate in a very small and pointed lobe. 



(2) Count Mannerheim has published a splendid Monograph of this subgenus, 

 an extract from which, with the plates, is found in the third volume of the An- 

 nates des Sciences Naturelles, accompanied by some observations from myself on 

 the too great extent given to the subgenus by that author. The species he calls 

 the capucinus is in my opinion the only one that belongs to it, and such was the 

 original idea of him who established it. 



(3) Elater ovalis, Germ.; Elater fuscus, Fab., and some others from the East 

 Indies, collected there by M. de Labillardiere. 



(4) Dalm., Ephem. Entom., 1824. His Lissomus punctulatus is closely allied to 

 the Drapetes castaneus of Count Dejcan, and the Elater Ixvigatus of Fabricius. 



One species of this subgenus is found in Europe, the Elater equestris, Fab. ;
