Necrodes, Wilk, Silpha, Lin. Fab. 



Have the antennae manifestly longer than the head, termi- 

 nated in an elongated knob, of five articulations. The 

 second is larger than the third. The body is an oblong-oval, 

 with the corslet almost orbicular, broader in its middle, the 

 legs narrow, elongated, a little widened at the end, and ter- 

 minated by two spurs of ordinary size, and the cases truncated 

 obliquely. 



Species of this sub-genus are found in Europe, in the 

 equatorial countries of the New World, in the East Indies, 

 and New Holland.* 



Sometimes the body is ovaliform, or ovoid, with the head 

 but little or not at all strangulated posteriorly, and more nar- 

 row than the corslet. The corslet is either almost semi-circu- 

 lar, and truncated in front, or trapezoid, and broader behind. 

 The elytra are rounded, or simply emarginated at their 

 posterior extremity. The hinder feet do not differ at all, or 

 at least very little, sexually. 



The jaws are armed internally with a tooth or scaly 

 crotchet. 



Silpha (Proper), Lin. Fab. Peltis^ Geoff., 



Whose body is almost in the form of a buckler depressed, or 

 but little elevated, with the corslet semi-circular, truncated, 

 or very obtuse in front, the elytra strongly edged, and hol- 

 lowed into a gutter externally, the palpi filiform, and the last 

 articulation is almost cylindrical and terminated in a point in
