LIMNOBARIS. 349 
armed with a minute curved tooth on the lower edge towards the apex, the apical uncus almost obsolete ; 
tarsal claws narrowly separated. 
Length 3, breadth 14 millim. (<¢.) 
Hab, Nicaraava, Chontales (Janson). 
- One male. A narrow, oblong, flattened form, with finely seriato-squamose elytra, 
tumid, unimpressed, bispinose prosternum, and broad tibiz, the anterior pair armed 
with a minute curved tooth on the lower edge towards the apex. J. dentifer is of 
about the same size and shape as the N.-American L. tabida, Casey, except that the 
elytra are more parallel-sided. The males of various species of Centrinites have a 
somewhat similar tooth on the intermediate and posterior tibiz, and that of Platybaris 
lamellifer a lamelliform prominence on the anterior tibie; but these insects are not 
otherwise very nearly related to Limnobaris. 
10. Limnobaris uniformis, sp.n. (Tab. XVII. figg. 34, 34a, 2.) 
Centrinus uniformis, Schm. in Mus. Brit. 
Elongate-ovate, flattened above, nigro-piceous, the antenne (the club excepted) and tarsi ferruginous ; above 
and beneath sparsely clothed with very small, narrow, cinereous scales, the vestiture on the prothorax 
confined to a broad space along the sides, that on the elytra arranged in two or three close lines down 
each interstice (the first with one line only). Head sparsely, very finely punctate, with a sharply-defined 
transverse groove between the eyes; rostrum feebly curved, very slender, about as long as the head and 
prothorax, punctured at the base, the antenne inserted at about the middle, the antennal club acuminate- 
ovate. Prothorax a little broader than long, constricted in front, the sides rounded anteriorly ; closely, 
finely punctate, the punctuation becoming denser at the sides and sparser on the disc. Scutellum bare, 
oblong. Elytra long, a little wider than the prothorax, obliquely truncate at the shoulders; sharply, 
narrowly striate, the interstices closely punctate. Beneath closely punctate. Prosternum foveate at the 
middle of the subapical groove. Anterior coxe separated by about their own width. Tarsi with joint 3 
large, the anterior pair with joint 2 strongly transverse. 
Length 44, breadth 2 millim. (9.) 
Hab. Nicaraaua, Mosquito coast (Mus. Brit.). 
One specimen (with the pygidium dragged out), which has stood for many years 
under the above-quoted MS. name in the British Museum. It has the upper portion 
of the mesothoracic epimera visible from above, the mandibles acutely toothed on their 
inner edge, the penultimate tarsal joint largely developed, and the elytral interstices 
closely punctate. The long, slender rostrum (@ ), the transversely-grooved head, the 
more widely-separated anterior cox, the sparser vestiture of the under surface, &c., 
distinguish Z. wniformis from the nearly-allied L. T-album (L.), of Europe. LL, recti- 
rostris (Lec.) is very like L. wniformis, but it has a more coarsely punctured prothorax, 
sparsely punctured elytral interstices, and scattered vestiture. 
11. Limnobaris languida, sp. n. (Tab. XVII. figg. 86, 36 a, ¢.) 
Oblong-ovate, flattened above, rufo-piceous, the antenne and legs ferruginous ; uniformly clothed with small, 
narrow, flavo-cinereous scales, which are arranged in two lines down each elytral interstice (the first with 
one line only); the vestiture of the under surface closer, fine, and whitish. Head finely punctate ; 
rostrum arcuate, about as long as the head and prothorax, moderately stout, closely punctate, and
