BRITISH BEETLES. 
The Crypticina are here represented solely by 
Crypticus quisquilius (Plate X., Fig. 2), a small, black, 
shining species found in some numbers on sandy banks 
at Deal. It has slender’ legs and tarsi, the hinder 
femora not reaching far beyond the elytra, of which 
the epipleurse are narrow. It is usually winged, but 
individuals occur in which the wings are either im- 
perfectly developed or absent. In this family there is 
a narrow projection between the anterior coxm. 
The Pedinina have the eyes divided into two by the 
lateral margin of the head ; they include one British 
species, Heliopathes gihbus, abundant in hot sandy 
places by the sea. It is deep-black in colour, shining, 
oblong, of clumsy shape, with coarsely punctured 
elytra, the epipleur® of which are conspicuously ridged 
at the shoulder, the anterior tibiae are triangular, and 
the three basal joints of the front tarsi strongly 
widened in the male, in which sex the posterior femora 
are fringed beneath. 
The larva is filiform, cylindrical, whitish, with a 
brown head and thorax, and strong fossorial front 
legs : the head and tail are slightly hairy, and the 
apex of the abdomen is furnished with eight erect 
tubercles. 
The Opatrina have the tarsi simple in both sexes, 
and present numerous other smaller differences from 
the Pedinina, with which they are sometimes asso- 
ciated. Our two species have the eyes divided, and 
the clypeus deeply notched (as in Heliopathes) ; but 
in Opatrum the maxillary palpi have the last joint 
hatcliet-sliaped, whilst in Microzoum it is almost ovate. 
Both are dull black and somewhat depressed ; and 
occur in similar places to the Pedinina. 0. sabulosum
