and Central and South America only about as many more. Two species 
have been found fossil in Europe and two in America, the latter at Florissant 
only. One of the European species, 7. manderstjernai Heyden from Rott, 
appears to be quite too large for a Tychius and is preserved in such a 
position as hardly to allow proper comparison with the American fossils; 
the other, 7. latus Forster from Brunstatt, differs much from the American 
species, is stouter, and has the beak imperfectly preserved.

TYCHIUS SECRETUS. 
Plvyr, Fis: 12: 
Body moderately elongate, the dorsum well and regularly curved. 
Head small, eye moderately large, transversely oval; beak as long as head 
and prothorax together, barely arcuate, moderately slender, very delicately 
punctulate. Thorax tapering rather rapidly from base, less than half as 
high again as long, uniform, rather coarsely and densely punctate. Elytra 
fully twice as long as broad, rather finely striate and apparently very faintly 
punctate in the strize.

‘T'YCHIUS EVOLATUs. 
Pl. v1, Figs. 11, 13, 17. 
Body rather elongate, the dorsum moderately curved. Head small, 
not much higher than long, feebly but not very finely punctate; eye of 
moderate size, circular, or slightly oval in a transverse sense; beak some- 
what longer than the prothorax, almost straight or feebly arcuate, slender. 
Thorax tapering regularly from base, considerably more than half as high 
again as broad; densely, heavily, but not very coarsely punctate. Elytra 
fully two and a half times longer than broad, punctato-striate, the inter- 
spaces flat and apparently feebly and obscurely punctate.
