third and fourth together, the sutures straight to the margin. Under sur- 
face punctate like the thorax, but somewhat more finely. 
Length, excluding rostrum, 6™™; height, 2-4"; length of elytra, 45™"; 
of rostrum, 3°6™™. 
It bears a close general resemblance to Balaninus flexirostris from the 
same beds.

ERYCUS Tournier. 
This genus is principally European, half a dozen species being known 
there, of which one is also found in North America, together with an addi- 
tional species found in the northernmost United States and northward. 
Flach figures two of the European species as found in the Pleistocene 
deposits of Hésbach, Bavaria, and a single fossil species has been found at 
Florissant. The Hésbach specimens are known principally: by their elytra, 
that of E. acridulus being not unlike ours, but the proportions of.the thorax 
are widely different, and our fossil is a much larger species. 
ERYCUS BREVICOLLIS. 
Pio ehios 19s 
Head feebly and not finely punctured; eye large, transversely broad 
ovate and pointed beneath, situated low down at the base of the rostrum, 
which is twice as long as the prothorax, strongly and regularly arcuate 
Prothorax half as high again as long (in this respect disagreeing with Ery- 
cus), regularly arched above, with broad and rather full but not very distinct 
postocular lobes, the surface closely and distinctly punctate. Elytra gradu- 
ally tapering in the apical half, the humeri rounded, strize with long quadrate 
approximate punctures, the interspaces feebly punctate. Legs much as in 
our FE. puncticollis LeC., but with less abruptly clavate thighs, not toothed, 
the appearance of a tooth on the fore femora being an accident of preser- 
vation.
