PSEUDOBARIS. 447 
strongly constricted in front, transversely depressed on the disc behind ; very sparsely, minutely punctate, 
except along the abbreviated, smooth, narrow median space. Elytra much wider than the prothorax, 
undulate on the disc, each armed at the apex with an acute dentiform prominence; with faintly punc- 
tured fine strie, the interstices broad, flat, narrowly costate on the apical declivity, each with a row of 
excessively minute scattered punctures. Beneath very sparsely, finely punctate. Prosternum with a 
sharply-defined sulcus ending abruptly between the cox, the basal process flattened and almost smooth. 
Legs slender ; femora unarmed. 
Length 3-34, breadth 14-13 millim. (d 2.) 
Hab. Muxico (Truqui, in Mus. Brit.), Zacualtipan in Hidalgo (Hoge). 
Four specimens. A species nearly related to P. acutipennis, but with the upper 
and under surfaces much smoother, the prothorax transversely depressed at the base 
(so as to appear gibbous in front when viewed in profile), the antennal club larger. 
45. Pseudobaris subrugosa, sp. n. 
Oblong-ovate, subopaque, black, beneath shining and with a faint zneous lustre; the punctures on the under 
surface and legs each bearing a minute scale. Head closely punctate, transversely depressed between 
the eyes; rostrum strongly arcuate, stout, about as long as the head and prothorax, closely punctate, 
in the ¢ smoother and more slender, the antenne inserted at (d ) or slightly behind ( Q ) the middle. 
Prothorax transverse, arcuately narrowing from the base, constricted in front; closely, rather coarsely 
punctate, except, along the median line, the interspaces finely alutaceous. Elytra much wider than the 
prothorax, oblong, depressed along the suture, the humeri not prominent, the apices each armed with a 
triangular tooth; with sharply-cut, feebly punctured stria, the interstices broad, flat, narrowly costate 
on the apical declivity, strongly, transversely strigose. Beneath coarsely, the abdomen sparsely and 
finely, punctate. Prosternal sulcus deep, straight. Legs rather slender ; femora unarmed. 
Length 3-3,5, breadth 12 miliim. (d .) 
Hab. Mexico (Truqui, in Mus. Brit.), Amula in Guerrero (I. H. Smith). 
‘Two specimens. LP. subrugosa may be described as a form of P. callosipennis with 
strongly, transversely strigose elytral interstices, and broader and deeper strie, the 
third interstice neither widened nor squamose at the base, and the prothorax more 
coarsely punctured. P. rugipennis has somewhat similarly sculptured elytra, but in 
that insect the prothorax is broader and very coarsely sculptured, and the elytra are 
unarmed at the apex. 
46. Pseudobaris minuscula, sp. n. 
Oblong-ovate, moderately shining, black with a brassy lustre, the punctures on the under surface and legs 
each bearing a minute scale. Head minutely punctate, transversely grooved between the eyes ; rostrum 
(¢) arcuate, stout, about as long as the head and prothorax, finely punctate, (Q)a little longer and 
smoother, the antenne inserted near the middle in the ¢ and arising from nearer the base in the @. 
Prothorax coarsely, closely punctate. Elytra sharply striate, the striz becoming deeper and more coarsely 
punctate anteriorly, the interstices flat, narrowly costate at the apex, each with a single row of fine, 
shallow, transverse punctures, the apices (as seen in profile) usually very feebly and obtusely produced. 
Beneath coarsely, the abdomen finely, punctate. Prosternal sulcus deep, straight, sharply margined, 
open behind. Femora unarmed, 
Length 23-8, breadth 1-12 millim. (¢ ¢ .)
