Case II.

Order COLEOPTERA, or Beetles, commences with 
the families of the Cicindelidac and Carabidse, or Ground 
Beetles. 
(B.) Carabidse continued. Byticidse and Hydrophilidse, 
or Water Beetles. 
(C.) Staphylinidae, Buprestidse ; the elytra, or wing cases 
of some of the insects belonging to the latter family* are 
frequently used iu India to ornament ladies’ dresses. Lam- 
pyridae; the common glow worm belongs to this family; 
but the female insect only is apterous, and emits a phos¬ 
phorescent light. Silphiadae, or burying beetles. Sca- 
rabseidse; there are two specimens in this compartment of 
the celebrated Sacred Beetle of the Egyptians ( S. sacer ), 
of which numerous representations in stone, &c., may be 
seen in the Gallery of Antiquities. 
Case 12. 
(B.) Bynastidse and Cetoniidse: to the former family 
belong some of the largest coleopterous insects, and the 
latter are remarkable for their brilliant colours, and metallic 
tints. 
(E.) Lucanidae: in this family is the Stag Beetle 
{ L . cervus), a German specimen of which is exhibited, re¬ 
markable for its enormous mandibles. This compartment 
contains many interesting specimens illustrative of the 
Heteromerous Coieoptera. Curculionidse ; amongst these 
is the Diamond Beetle ( Eniimus imperialis), an interesting 
object for the microscope.
