346 RHYNCHOPHORA. 
Hab. British Honpvuras, Belize (Blancaneaua: 3 ); GUATEMALA, Panzos (Conradt : 
$ 2); Costa Rica, Paso Real (Pittier: ¢), Puerto Limon (Knab, in U.S. Nat. 
Mus.: 3 Q). 
Seven specimens, the prosternal spines in the three males varying greatly in 
development. Very like Z. latidens, but with the upper surface almost bare, the 
anterior femora unarmed, the anterior cox widely separated, the scutellum sub- 
quadrate, the prosternum of the female bifoveate anteriorly, the second joint of the 
funiculus scarcely longer than the third. The extreme tip of the last dorsal segment 
is usually visible. The undescribed Baris complanata of Dejean is very like the 
present insect. 
4, Limnobaris quadricollis, sp. n. (Tab. XVII. figg. 33, 33 a, 2.) 
Elongate, flattened above, shining, black, the legs and rostrum piceous, the base of the antennze ferruginous ; 
the upper surface almost bare, the under surface and legs sparsely clothed with minute whitish scales. 
Head finely punctate, transversely sulcate between the eyes ; rostrum curved, about as long as the pro- 
thorax, moderately stout, punctate-striate, the apical half more slender and somewhat closely punctate ; 
joint 2 of the funiculus very short, narrower than 3. Prothorax nearly as long as broad, subquadrate, 
the sides rounded anteriorly, the anterior lobe narrow ; closely, rather coarsely punctate, except along a 
narrow space down the middle. Scutellum subquadrate. Elytra subparallel at the base ; deeply striate, 
the striw feebly punctate, the interstices flat, uniseriate-punctate, the second with a double row of 
punctures towards the base. Beneath closely punctate, the punctures on the pro-, meso-, and meta- 
pleura coarse and confluent. Prosternum flattened, bifoveate in the anterior constriction. Anterior 
_ cox distant, separated by more than their own width. 
Length 4-44, breadth 17-13 millim. ( 92.) 
Hab. Brrrish Honpuras, Belize (Blancaneauxr) ; GuaTEMALA, Panzos (Champion). 
Three females. More elongate than L. calandriformis, the prothorax subquadrate 
and nearly as long as broad. Broader, less attenuate, and flatter above than the 
N.-American L. nasutus *, the prosternum doubtless bispinose in the male, bifoveate 
near the apex in the female, as L. calandriformis. 
5. Limnobaris confusa. 
? Centrinus confusus, Boh. in Schénh. Gen. Cure. iii. p. 740'; Mann. Bull. Mosc. 1843, 2, p. 293°. 
Centrinus confusus, Lec. Proc. Am. Phil. Soc. xv. p. 816°. 
Limnobaris confusa, Casey, Aun. N. York Acad. vi. pp. 626, 637 *. 
Hab. Norts America, Southern and Western States *, Florida! ?4, California 1! 2.— 
Mexico (Trugui, in Mus. Brit.: 2), Teapa (1. H. Smith: 3); Costa Rica, Zent and 
Banana River (Krab, in U.S. Nat. Mus.: ¢ 2); tPanama (coll. Fry, in Mus. Brit.: ¢ ). 
Three males and two females are referred to the species identified as Centrinus 
confusus, Boh.f, by Leconte and Casey. One of the males, from Teapa, with short 
* LIimnobaris (Bartdius) ethiops, Kirsch, from Peru, the type of which I have seen, is nearly related to 
LL. nasutus. 
+ Boheman describes C. confusus as having a “semirotundate pygidium,” due probably to the abdomen 
being somewhat pulled out.
