LIMNOBARIS., 351 
the prothorax, two interrupted fasciz on the elytra (one just below the base, and the other at about one- 
third from the apex), and the metathoracic episterna, somewhat thickly clothed with rather coarse, narrow 
white scales, the rest of the under surface and the legs with scattered minute white scales. Head 
transversely grooved between the eyes; rostrum rather slender, feebly arcuate, barely as long as the 
prothorax, finely punctate, smooth along the middle, the antennal club ovate. Prothorax transverse, 
rounded at the sides, narrowed and feebly constricted in front ; sparsely punctate on the disc, densely so 
along the outer margin. Elytra a little wider than the prothorax, oblong; narrowly striate, the strie 
distinctly punctate towards the suture, the interstices broad, flat to near the apex, the bare portions 
smooth. Beneath very sparsely and finely, the prosternum closely and coarsely, punctate, the latter 
unimpressed. Anterior coxe separated by about their own width, Tarsi with the bilobed penultimate 
joint broad and joint 2 of the anterior pair strongly transverse. 
Length 3), breadth 14 millim. (@.) 
Hab. Panama (coll. Fry, in Mus. Brit.). 
One female. The albo-bifasciate elytra and the white-margined, laterally-rounded 
prothorax distinguish the present species. It is more shining than L. bicincta, the 
prothorax is more rounded at the sides and more sparsely punctate on the disc, the 
mandibles are strongly decussate, and the rostrum (@ ) is slender and feebly curved. 
14. Limnobaris desidiosa, sp.n. (Tab. XVIII. figg. 4, 4a.) 
Oblong-ovate, shining, piceous or rufo-piceous ; above and beneath (the flanks of the prothorax excepted) some- 
what sparsely clothed with coarse, narrow, whitish scales, which are condensed on the prothorax into a 
broad marginal stripe and on the elytra into a single line down each interstice. Head minutely punctate, 
transversely sulcate between the eyes ; rostrum strongly arcuate, about as long as the head and prothorax, 
rather stout, sparsely, very finely punctate, the antenne inserted near the middle. Prothorax transverse, 
rounded at the sides anteriorly, feebly constricted in front; coarsely, closely punctate, except along the 
narrow smooth median space. Scutellum very small, smooth, triangular. Elytra gradually narrowing 
from the base, very little wider than the prothorax ; deeply punctate-striate, the interstices about twice 
the width of the strie and somewhat coarsely uniseriate-punctate. Beneath closely, coarsely punctate. 
Prosternum unimpressed behind the deep transverse subapical groove. Anterior cox separated by a 
little less than their own width. Tibi strongly unguiculate. 
Length 33-34, breadth 13-13 millim. (2 ?) 
Hab. Mexico, Vera Cruz (fége). 
Three specimens. ‘The coarse vestiture, the deeply striate elytra with conspicuously 
uniseriate-punctate interstices, and the coarsely punctured prothorax, distinguish 
L. desidiosa. The mandibles are acutely dentate within. 
15. Limnobaris discreta, sp.n. (Tab. XVIII. figg. 5, 5a, 3.) 
Oblong-ovate, flattened above, shining, piceous, the legs (and in one specimen the rostrum also) ferruginous ; 
the prothorax with a spot at the middle of the base and a marginal stripe on each side, and the elytra in 
part (a large, common patch on the disc below the base, and small spot on each of the humeral and sub- 
apical callosities, remaining bare), somewhat thickly clothed with oblong whitish scales; the under 
surface and rostrum sparsely set with similar scales. Head minutely punctate, transversely grooved 
between the eyes; rostrum cylindrical, arcuate, moderately stout, about as long as the head and prothorax, 
seriato-punctate, the antenne inserted at (2) ora little beyond ( ¢ ) the middle, the antennal club ovate. 
Prothorax broader than long, narrowed and feebly constricted in front, rounded at the sides anteriorly ; 
closely punctate, except along a narrow space down the middle and on an oblong space towards the sides. 
Scutellum minute, triangular. Elytra barely twice the length of the prothorax, conjointly rounded at
