The genus Choleva, or, as it used to be called, Catops, contains more 

 than a hundred species, the majority of which are found in Europe and 

 the adjacent countries ; representatives, however, are known from North 

 and South America (Caraccas, Chili, &c.), and also from Tasmania, and 

 it is probable that the genus is very widely distributed ; they are of a 

 dull black or fuscous, occasionally red-brown colour, and are found 

 chiefly in the carcases of birds or small animals, or in fungi ; a few live 

 in ants' nests ; they are exceedingly active in their movements and are 

 in many cases soft and fragile, so that care is required in their preserva- 

 tion, and they should, if possible, be mounted soon after their capture ; 

 they may be distinguished from Colon by the small eighth joint of the 

 antennse, and by their abdomen having six distinct segments instead of 

 five ; in many points, such as length and stoutness of antennae, pubes- 

 cence, size, shape, dilatation of tarsi in male, &c., they differ considerably, 

 and in consequence have been divided into several genera by Thomson 

 and others ; one of these, Catoj>s, Payk, is evidently distinct, but it 

 seems better to consider the others as at the most sub-genera ; the species 

 vary considerably in size (froin 1 or 1| to 5 mm.), and are of an oval or 

 oblong-oval form, with more or less distinct fine pubescence ; the elytra 

 are, as a rule, very finely sculptured, and, except in the first sub-genus, 

 the striiie, with the exception of the sutural stria, are either entirely 

 wanting or very obsolete. 



The larva of C.fusca is described and figured by S<hi6dte, I. p. 36, PI. x., Pig. 1 ; it 

 is broad in front and much narrowed behind, pale, with the corneous parts fuscous; 

 the head is small, about one-fourth as broad as the prothorax ; the antenna) are longer 

 than the head and have the second joint elongate ; the prothorax is large and ample, 

 considerably rounded in front, longer than cither meso- or metathorax. but of equal 

 breadth wiuh these segments; the abdominal segments are all considerably narrower 

 tlian the thoracic segments, and gradually decrease in size; the nintli is much 

 narrower than the eightii, and bears two very long slender ccrci ; the anal appendage 

 is cylindrical, longer than the ninth segment; legs long aud slender; the dorsal
