I have seen the types of the species described by Boheman, Kirsch, and Solari, 
and am unable to separate them. The prosternal depression (into which the antennal 
club is received in repose) is broad and deep, and it extends backward between the coxe 
as in the N.-American A. ater and A. elongatus, Lec. The elytra (and sometimes 
the prothorax also) are partly or almost entirely reddish-brown, and very finely striate, 
the sutural stria shallowly catenulate-punctate. The rostrum is stout and arcuate, 
longer in the female than in the male. ‘The length varies from 2-3 mm. 
2. Ampeloglypter sulcifrons, sp. n. 
Oblong, rather convex, very shining, black, glabrous. Head almost smooth, deeply, transversely suleate 
between the eyes ; rostrum stout, arcuate, scarcely so long as the head and prothorax, the basal portion 
sparsely punctate, the antenne inserted at about the middle, the club rather large. Prothorax transverse, 
abruptly narrowed and tubulate in front, the sides rounded anteriorly and subparallel at the base; very 
sparsely, minutely punctate and with a row of coarser punctures along the basal margin. Elytra a little 
wider than the prothorax, transversely depressed at the sides below the humeri and beyond the middle ; 
very finely striate, the striz faintly punctate, the interstices smooth. Pygidium transverse, short, finely 
punetate. Beneath sparsely punctured, the punctures coarse along the sides. Prosternum with an 
oblong-trapezoidal excavation extending backwards between the coxe, which are separated by considerably 
more than their own width. 
Length 22, breadth 13 millim. (<¢.-)
