384: Rev. T. A. Marshall on new Genera 
with or without cyaneous blotches or black dots, usually four in 
number, upon the elytra, which, in a few instances, are wholly 
cyaneous. ‘The thorax is always testaceous. 
Four species have hitherto been described—4-maculata, Oliv., 
granulata and chloroptera, Germ., and testacea, Fab. Chevrolat 
(D’Orbigny’s Dict. s. v. Metazyonycha) gives Eumolpus pictus, 
Perty, as appertaining to the genus. I have a specimen of this 
insect before me, from the Marquis la Ferté’s collection, where 
it stands as Endocephalus pulchellus, De}. It belongs to a widely 
different group, and will probably form a new genus, allied to 
Endocephalus. 
Eighteen or twenty undescribed species appear to exist in 
collections. Those which I have before me may be thus tabu- 
lated :-—
