42. Pseudobaris plicata, (Tab. XXI. figg. 28, 28a, ¢.) 
g. Baridius plicatus, Boh. in Schénh. Gen. Cure. viii. 1, p. 180°. 
Hab. Mexico!, Omilteme in Guerrero (H. H. Smith), Toxpam, Oaxaca (Sallé) ; 
GUATEMALA, Quiché Mts. (Champion). 
The type of this insect, a somewhat immature male, eneous in colour, kindly 
communicated by Dr. Sjéstedt, is more elongate than P. acutipennis, and has the 
prothorax straight at the sides and abruptly constricted in front, the elytra subparallel 
at the base and undulate on the disc, and the first ventral segment sulcate down the 
middle. Various specimens from Omilteme, Toxpam, Oaxaca, and Quiché are pro- 
visionally referred to it; these examples, however, have the prothorax less abruptly 
constricted in front and the first ventral segment simply flattened down the middle in 
the male. 
43. Pseudobaris subcaudata, sp. n. 
Oblong-ovate, shining, black with a faint brassy lustre; the third elytral interstice with a small oblong patch 
of narrow whitish scales at the base; the punctures of the under surface and legs each bearing a minute, 
hair-like, white scale. Head finely punctate, transversely depressed between the eyes; rostrum (¢ ) 
arcuate, stout, a little longer than the head and prothorax, closely, finely punctate, (2 ) much longer, 
smoother, and comparatively slender, the antenne inserted at (¢) or behind( @ )the middle. Prothorax 
transverse, gradually narrowing from the base, constricted in front; rather sparsely punctate, smooth 
along the median line. Elytra moderately long, very gradually narrowing from the rounded humeri, 
undulate on the disc, and each with an angular prominence at the apex; sharply striate, the interstices 
broad, flat, sharply costate at the apex, obsoletely uniseriate-punctate, 3 widened at the base. Beneath 
closely and coarsely, the abdomen sparsely and finely, punctate ; first ventral segment flattened down the 
middle in the ¢. Prosternal sulcus deep, straight, and sharply margined. Legs rather slender; femora 
unarmed. 
Length 34-4, breadth 13-14 millim. (¢ 9.) 
Hab. Guaremata, Duefias, San Gerdnimo (Champion) ; Panama, Volcan de Chiriqui 
4000 feet (Champion). 
Nine specimens, all but one from Guatemala; these latter are taken as the types. 
‘This insect has exactly the facies of P. apicalis (Boh.), and occurs with it in the two 
Guatemalan localities, but is easily separable therefrom by the dentate apices of the 
elytra, the more slender legs, and the slender, narrower, and less flattened rostrum of 
the female. The single example from Panama has the apical prominences feebly 
developed. P. subcaudata is more elongate than P. acutipennis and P. callosipennis, 
approaching P. plicata in this respect. 
44, Pseudobaris gibbicollis, sp. n. (Tab. XXI. fig. 29, ¢.) 
Oblong-ovate, very shining, nigro-eneous ; the third elytral interstice with a short streak of narrow whitish 
scales at the base, the. punctures on the under surface and legs each bearing a minute scale. Head 
sparsely, minutely punctate, transversely depressed between the eyes ; rostrum arcuate, about as long as 
the head and prothorax, stout, sparsely, very finely punctate, in the 2 a little longer, smoother, and 
more slender, the antenne inserted at (¢) or slightly behind ( ) the middle, the club large and with 
cuuspicuous sutures. Prothorax much broader than long, arcuately narrowing from the base and
