32 COLEOPTERA. 



European species, is shining pitchy brown, with rather prominent 

 mandibles, and measures about half an inch in length. The genus 

 Nemozoma, Latr., differs considerably from the rest of the family 

 in shape ; Nemozoma Elongatum, Linn., the typical European 

 species, is very long and narrow. It is black, with reddish- 

 yellow legs and antennse, and measures about one-fifth of an inch 

 in length. This beetle and its larva live in the galleries of wood- 

 boring beetles, and devour their larvse. 



FAMILY YttlCofydiidce. 



Tarsi four-jointed ; front and middle coxae globular ; hind coxae 

 transverse. 



Includes a number of small species, most of which are found 

 under bark, or among rotten wood and other decaying vegetable 

 substances. The European species of the typical genus Colydium, 

 Fabr., are rather long and narrow beetles, about a quarter of an 

 inch in length, and are black, with reddish legs and antennas. 



FAMILY IX. Cucujidce. 



Tarsi four-jointed ; antennse long, hardly clubbed ; body long, 

 parallel, and flattened. 



A family of small extent, but more interesting than the last. 

 Most of the species are exotic, and the majority of those whose 

 habits are known live under bark, though some are found in ants' 

 nests. 



Passandra Brasiliensis, Chevr., is of a pitchy-black colour, and 

 nearly an inch long. It somewhat resembles a Scarites in 

 appearance, but is flatter, and its four-jointed tarsi would im- 

 mediately distinguish it. The species of the typical genus Cucujus, 

 Fabr., are bright scarlet insects about half an inch long ; about six 

 or eight species are known, which are met with in Europe, North 

 America, and the East Indies. Most of the Cucujidce, however, 

 are of a shining black colour. 



FAMILY X. Cryptopliagidce. 



Tarsi five-jointed (hind tarsi four-jointed in the females of same 

 species) ; antennse with a well-marked club ; first segment of the 

 abdomen very large. 



The beetles of this family are all of small size, and are gener- 

 ally found among decaying vegetable matter, in fungi, under bark, 

 among dead leaves, etc. Cryptopliagus Lycoperdi, Herbst, a reddish-
