claim to be regarded as Ceramlyces is founded not only 
upon oeconomy and habit, but likewise upon character, 
these insects exhibiting all the genuine characters of that 
genus, particularly the lunar or rcniform eyes, so happily 
noticed by DeGeer, who arranges them with those Ceram- 
lyces that have a globose depressed thorax, from which 
Mr. Marsham has judiciously separated them. 
Fabricius originally considered this family as forming 
part of his genus Callidium ; but in his Sy sterna Eleuthe- 
ratorum , after Schrank, he has made a new genus of them, 
under the name of Clytus. Latreille, however, a most 
accurate observer, and who has entered more deeply into 
the anatomy of insects than almost any entomologist of the 
present age, still regards them merely as a family or section 
of Callidium. (Hist. Nat. Gen. et Part, des Crustac. et des 
Ins. t. iii. p. 217 .) 
The body of Ceramlyx fulminans is black beset with 
cinereous hairs, which underneath and upon the legs are 
so thinly scattered as scarcely to obscure their blackness. 
Head channelled longitudinally. Antennse of the length 
of the body, at the base whitish with cinereous hairs. 
Thorax with a large obcordate velvety black spot, and two 
smaller oblong-oval lateral ones. Scutellum black edged 
with cinereous hair. Elytra dehiscent at their apex, black, 
pencilled with unduiato-angular cinereous transverse lines, 
formed of hair. A cinereous crescent also ornaments their 
tips. Wings black. 
The males in this genus have usually longer antennae 
than the females; a circumstance which will account for a 
difference observable between the description of Fabricius 
and that above given. He says: “ Antenna breves ,” 
whereas in our specimen they arc as long as the insect. 
He also describes the body of his as fuscous : in ours it is 
quite black. Notwithstanding these differences, we make 
our reference to him without hesitation, since in every 
other respect our specimen answers exactly to his descrip- 
tion.
