THE ECPODA, OE PIIYTOPOAGA. 
207 
The little Lamprosoma concolor is so exceedingly 
unlike its allies, both in size, shape, and colour, as to 
seem at first sight misplaced in this tribe ; by some 
authors it is placed under a different one, the Eumol- 
pina. Its structure will be readily understood from 
its old generic name, Odmorphus, or egg-shaped ; and 
it much resembles certain species of Phsedon in the 
Chrysomelina. 
The Cuyptoceph alina, also, have the head vertical, 
and sunk in the thorax; the body being cylindrical, 
and seeming to be truncate in front. Their antennae 
are long and filiform ; their thorax margined ; their 
pygidium not entirely covered by the elytra, and their 
eyes kidney-shaped. 
Our single genus, Cryptocephalus, contains many 
brilliant species, found on hazel, oak, birch, sallow, 
&c. They are only to be seen during fine weather, 
and chiefly in the hottest part of the day, retiring 
when the sun is overclouded. The approach of the 
net, and sometimes even the step or shadow of the 
collector, is enough to make these wary little beauties 
drop from their leafy perch. Their larvae are enclosed 
iu cases somewhat like those of Clytlira, supposed to 
be formed of earth, but which in one case has been 
found to consist of the excrement of the larva, moulded 
into shape with its mandibles. 
The sexes vary somewhat in this genus, the males 
being usually less bulky, and having longer legs and 
antennae. In G. coryli, found on hazel bushes at 
Darenth in June, the female is entirely red, while the 
male has a black thorax. 
G. sexpunctatus, found in the same place, and at 
Cobham, Kent, is elegantly spotted ; though the palm
