BEETLES. 79 



Fhricobacis Marginatus, Guer., somewhat resembles a Cassida in 

 the shape of the elytra, though very different otherwise. It is 

 violet-black, with two yellow spots on each of the elytra, and is 

 about three-quarters of an inch in length. 



SECTION XIV.— PSEUDOTRIMERA. 



Tarsi generally three-jointed ; antennae generally short, with a 

 three-jointed club ; elytra covering the abdomen, and never trun- 

 cated at the tips. 



Family I. — EndomycUdcB. 



Body oval ; antennae eleven-jointed, longer than the head and 

 thorax, and inserted on the front of the head, the three terminal 

 joints forming a long club ; maxillary palpi filiform, a little 

 thickened at the end, but not terminated by a large securiform 

 joint ; femora thickened ; claws simple. 



The beetles belonging to this ftimily are not very numerous ; 

 they are generally of small size, and are found in fungi, or under 

 bark. It will suffice to enumerate one or two representative 

 species. In Dapsa Barbara, Luc, the antennae are less thickened 

 than in Endomijclms ; it is an Algerian species, measuring about 

 a quarter of an inch in length, and is of a reddish colour. 



Endomychus Coccineus, Linn., the type of the family, is a bright 

 red beetle, with two large black sjjots on each of the elytra ; the 

 head, antennae, legs, and middle of the thorax are also black. 

 The beetle is nearly a quarter of an inch long, and is not rare in 

 some localities. 



Family II. — Coccinellidce. 



Body hemispherical, rarely oval; antennae insei'ted on the sides 

 of the face near the base of the mandibles, concealed by the head 

 when at rest, generally eleven-jointed and clavate, seldom as long 

 as the head and thorax ; maxillary palpi with the last joint large, 

 and generally securiform; claws simple or bifid; habits carnivorous, 

 at least in the typical species. 



The Coccinellidce or Lady-birds comprise an extensive series of 

 beetles, generally of small or moderate size, and of varied colours. 

 Most of the European species are black, with red or yellow spots, 

 or red or yellow, with black spots. Two of the commonest species 

 are the Seven-Spot Ladybird (Coccinella Scptempunctata, Linn.), and
