AMPELOGLYPTER. 389 
One male. Smaller and much smoother than the N.-American A. ater, Lec., the 
anterior coxee more widely separated, the prosternal excavation narrower, the antennal 
club larger. 
3. Ampeloglypter speculifer. (Tab. XIX. figg. 22, 22a, 3.) 
Ampeloglypter speculifer, Solari, Ann. Mus. Genova, xlii. p. 429 (1906) '. 
Hab. Mexico (Truqui, in Mus. Brit.), Teapa (LH. H. Smith); Brititsn Honpuras, Rio 
Hondo (Blancaneaux) ; GuatTemMALA, San Gerénimo and San Juan in Vera Paz 
(Champion) ; Nicaragua, Managua! (Solar) ; Cosra Rica, Surubres (Biolley) ; Panama, 
Bugaba, Taboga I. (Champion). 
The types of this species, like the various specimens found by myself in Panama, 
have the greater part of the under surface so densely punctate as to appear opaque, but 
in the four examples from ‘“ Mexico,” Rio Hondo, and San Gerdénimo the puncturing 
of this portion of the surface is more scattered and the narrow interspaces are shining. 
The prosternal excavation is deep and oval in shape, but it does not extend backward 
between the coxe. The elytral strive are a little more distinct than in A. ovalis. 
4, Ampeloglypter binodosus, sp. n. 
Oblong-subrhomboidal, somewhat flattened above, very shining, black, glabrous. Head minutely punctate, 
transversely depressed between the eyes above and shallowly sulcate between them beneath; rostrum 
strongly arcuate, rather slender, considerably longer than the head and prothorax, the basal portion 
sparsely, finely punctate, the antenne inserted behind the middle. Prothorax transverse, conical, 
constricted and tubulate in front; sparsely, minutely punctate. Hlytra a little wider than the prothorax, 
subtriangular, transversely depressed below the base; finely punctate-striate, the striz very faint, the 
interstices smooth. Pygidium transverse, small, densely punctulate. Beneath sparsely, rather finely 
punctate. Prosternum broadly flattened down the middle and with a deep oval fovea in front, the basal 
process sulcate and binodose. ‘Tarsal claws connate at the base. 
Length 3, breadth 12 millim. ( 2.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One female. Smaller than A. plicatipennis; the elytra less uneven, with more 
distinctly punctate striw, and the humeri not so prominent; the head not foveate 
beneath ; the legs less elongate; the basal process of the prosternum distinctly 
binodose. 
5. Ampeloglypter plicatipennis, sp. n. (Tab. XIX. figg. 23, 23a, 2.) 
Oblong-rhombvidal, somewhat flattened above, very shining, black, the antenne rufescent at the base, glabrous. 
Head sparsely, minutely punctate, transversely depressed between the eyes above and deeply foveate 
between them beneath; rostrum rather slender, arcuate, considerably longer than the head and prothorax, 
the basal portion sparsely, finely punctate, the antennee inserted at about the middle. Prothorax 
transverse, conical, abruptly constricted and tubulate in front; sparsely, minutely punctate. Elytra 
rather long, subtriangular, wider than the prothorax, transversely depressed before and behind the 
prominent humeri, at the ‘sides beyond the middle, and before the apex, the suture also depressed 
anteriorly ; faintly punctate-striate, the second stria almost obliterated below the base, the interstices
