LIMNOBARIS. 345 
Twelve specimens, one of the males with the prosternal spines almost obsolete. 
Easily recognizable by the stout, oblique, blunt tooth on the anterior femora, ‘The 
uniseriately-arranged vestiture of the eclytral interstices becomes double towards the 
base, and this is particularly noticeable in the male. 
9. Limnobaris carbonaria. (Tab. XVII. figg. 30, 30a, 3.) 
9. Calandra carbonaria, Fabr. Syst. Eleuth. ii. p. 437°. 
9. Centrinus carbonarius, Boh. in Schéuh. Gen. Cure. viii. 1, p. 193 (nec Gen. Cure. ii. p. 748) *. 
Oblong-ovate, flattened above, shining, black, the prosternal spines and funiculus sometimes ferruginous; the 
elytra with an oblong patch at the base of the second interstice and a narrow line at its apex, an elongate 
streak on the fourth interstice beyond the middle, and sometimes some other spots at the base, densely 
clothed with hair-like ochreous scales, the rest of the upper surface almost bare, the under surface with 
scattered, hair-like, minute, ochreous scales. Rostrum arcuate, stout, not or very little longer than the 
prothorax, thickly punctate, the antenne inserted at the middle in both sexes, the antennal club ovate. 
-Prothorax nearly as long as broad, rounded at the sides anteriorly, narrow and tubulate in front ; 
sparsely, finely punctate, the punctuation becoming denser and closer at the sides and on the flanks, the base 
distinctly margined. Scutellum subquadrate. LElytra very little wider than the prothorax, broadly and 
conjointly rounded at the apex, the disc transversely depressed at the sides below the base ; sharply striate, 
the stria feebly punctate, the interstices flat, sparsely, minutely punctate on the disc, seriato-punctate 
at the sides, 6-9 narrowly costate towards the apex. Beneath sparsely punctate. Prosternum flattened 
between the anterior cox, which are separated by about their own width. Femora more or less clavate. 
3. Prosternum armed with two very long sinuous spines which extend beyond the front of the head (fig. 30 a), 
and also with an oblong deep cavity in the middle; anterior tibie sparsely ciliate within. 
Length 43-7, breadth 2-375 millim. (¢ 2.) 
Hab. Muxico, Toxpam in Vera Cruz (Sallé), Teapa (H. H. Smith); GuatTemaa, 
Senahu in Vera Paz (Champion) ; Nicaragua, Chontales (Belt); Panama, Lion Hill 
(Busck, in U.S. Nat. Mus.)—Sovrn Amurica!? (Mus. Brit.). 
Two males and four females. This insect has the general facies of a Cylindrocerus or 
Madarus. The long prosternal spines are similarly formed in the two males received *. 
3. Limnobaris calandriformis, sp. n. (Tab. XVII. figg. 52, 32a, ¢.) 
Subelliptic, rather broad, flattened above, shining, black, the tarsi, tip of the rostrum, prosternal spines, and 
base of the antennee more or less ferruginous; the upper surface almost glabrous, the under surface and 
legs with minute whitish hair-like scales, Head transversely sulcate and shallowly foveate between the 
eyes, finely punctate; rostrum moderately stout, about as long as the prothorax, striate and thickly 
punctate to the tip, tapering and with the apical half smoother in the @ ; joint 2 of the funiculus very 
short. Prothorax nearly as wide as the elytra, broader than long, the short anterior portion tubulate ; 
coarsely, closely punctate, the punctuation becoming sparser and finer along the middle of the disc. 
Scutellum subquadrate. Elytra not much longer than the prothorax, subcordate ; punctato-sulcate, the 
interstices flat, uniseriate-punctate, the series becoming double towards the suture. Beneath coarsely and 
very closely, the ventral segments more finely, punctate. Anterior coxee widely separated. Femora clavate. 
3. Prosternum with two very long sinuous spines and a deep excavation between them (fig. 32a), in unde- 
veloped specimens with two short straight spines placed further from the cox and a shallow excavation ; 
anterior tibiee finely ciliate on their inner edge, the anterior tarsi also with a few long hairs, 
Q. Prosternum flattened, bifoveate in the anterior constriction. 
Length 3-4, breadth 12-2 millim. (¢ 9.) 
* Our artist has unfortunately drawn (fig. 30a) a male with one of the spines broken off at about one-third 
from the base.
