LoMECHusA, Aleochara^ Grav., 



Which have no spines on the legs, and of which the antennae 

 from the fourth articulation, form a perfoliated club, or like 

 an elongated spindle, and the palpi terminate awl-like. The 

 antennas are often shorter than the head and corslet.* 



Tachinus, Grav., 



Which have spinous legs. The antennas are composed of 

 articulations like a reversed cone, or a pear, and thickening 

 insensibly, and whose palpi are filiform. -f- 



Tachyporus, Grav., 



Similar to the Tachini in the limbs and the antenna?, but 

 having the palpi terminating awl-like.J 



• Some have the corslet smooth, and not raised over its edges. Such 

 the Aleochara, bipmictata, lanuginosa, nitida {Staphi/Jimis bi-pustulatus, Lin. 

 Oliv. Col. III. 42, V. 44.) fumata, nana, of Gravenhorst, or his families, 

 iii. vi. (Col. Micropt. tom. 2.) The others have the edges of the corslet 

 raised, and form his genus Lomechusa ; L. paradoxa ; Slaphyl'mus emargi- 

 natus, Oliv. ibid- ii. 12; L. dentata, Grav. j Staphylinns strumosus, Payk. V.

 ib. v. 47; S. lunulatiis, Jau, See also, as well for this sub-genus as the 

 following, the second part of the first volume of the Insects of Sweden, 

 of M. Gyllenhall. There will be found excellent remarks on the several 

 differences of many species, and the application of which may be very 

 useful. 



The Tachini, which, such as atricapillus, have the corslet almost as long 

 as broad, the muzzle advanced, the four posterior tarsi sensibly longer 

 than their respective legs, appear proper to form a particular section.
