BARIS. 463 
Hab. Nicaracua (Sallé), Chontales ! (Belt, Janson). 
A large, shining, golden-cupreous, almost glabrous form, with a short, abruptly 
bent, apically flattened rostrum, a gibbous, coarsely punctured prothorax, a rather 
large, rounded, transverse scutellum, and undulate, deeply striate, coarsely punctate 
elytra, the intermediate and posterior tibie straight on their outer edge, the prosternum 
hollowed to receive the antenn, the mesosternum depressed, the pygidium carinate. 
‘The six specimens received by us are all of the female sex; the type isa male. ‘The 
S.-American B. metallescens, Boh., has similar sexual characters. 
11. Baris rugosissima, sp. n. (Tab. XXII. figg. 16, 16a, 2.) 
Oblong-ovate, rather dull above, shining beneath, black; the punctures on the elytral interstices, under 
surface, and legs each bearing a very minute scale. Head closely punctate, transversely grooved between 
the eyes; rostrum stout, short, barely as long as the prothorax, abruptly bowed from the middle, densely 
punctate. Prothorax transverse, arcuately narrowing from the base, feebly constricted in front; densely 
impressed with coarse, rounded punctures. Scutellum transverse. Elytra oblong, much wider than the 
prothorax, strongly undulate ; deeply, sinuately punctato-sulcate, the interstices almost flat, densely, 
coarsely, uniseriate-punctate, the third confusedly punctured, the ninth raised towards the apex. 
Beneath coarsely and closely, the abdomen more finely, punctate. Prosternum slightly depressed along 
the middle. ibis almost straight, narrow, feebly toothed at the outer apical angle. 
Length 44, breadth 2 millim. (@.) 
Hab. Mexico, “ Sierra de Durango” (Hége, ex Solari). 
One specimen, kindly presented to us by Signor Solari. An isolated form, with 
strongly undulate elytra, the punctures in the interstices as coarse as those of the 
strie, the prothorax coarsely punctate, the rostrum short and strongly bowed, the 
tibie narrow. B. aspera is perhaps the nearest allied Central-American species. 
12. Baris zapotensis, sp. n. 
Elongate-ovate, shining, black, the legs and antenne piceous or rufo-piceous; glabrous above, the punctures 
on the elytra and under surface each bearing a minute scale. Head very sparsely, minutely punctate, 
deeply, transversely grooved between the eyes; rostrum abruptly arcuate from the base, moderately 
stout, shorter than the prothorax, sparsely, finely punctate. Prothorax transverse, abruptly narrowed 
in front, the sides subparallel behind ; sparsely punctate, except along the smooth median line. Scutellum 
small, rounded. Elytra a little wider than the prothorax, oblong, gradually narrowing from the rounded 
humeri, feebly undulate on the disc and depressed along the suture from a little below the base to the 
apex ; with sharply-cut, narrow, faintly punctured strie, the interstices broad, flat, narrowly costate 
at the apex, cach with a row of minute scattered punctures. Pygidium separated from the short exposed 
portion of the last dorsal segment by a sharply defined transverse suture in the ¢, entire in the 9. 
Beneath sparsely punctate. Prosternum depressed along the middle. Tibiee almost; straight. 
¢ . First ventral segment somewhat flattened and the fifth with the apical margin slightly thickened at the 
middle. 
Length 33-32, breadth 14-12 millim. (¢ 9.) 
Hab. GuaTemata, Zapote, Pacific slope (Champion). 
Six examples. An oblong black form, with a very short rostrum, abruptly narrowed 
prothorax, a small scutellum, and sharply striate elytra, which are depressed along
