304 RHYNCHOPHORA. 
on the elytra, without visible pygidium in either sex. In one of the two males from 
Chiriqui and the one from Motzorongo the vestiture is as coarse as in L. @raria, but 
the ventral depression is similar to that of the same sex of L. eneola. The N.-American 
I. concinna (Lec.) is extremely like the present species, differing from it in its larger 
size, duller surface, and coarser vestiture. 
20. Limnobaris eraria, sp. n. 
Very like Z. wneola, but with the vestiture longer and coarser, arranged in a close line along each elytral 
interstice; the rostrum slightly longer in both sexes; the elytral strie rather deeper, the first 
conspicuously depressed before the middle; the first ventral segment of the g with a broad, shallow, 
closely-punctate, pilose depression. 
Length 2, breadth 3-59, millim. (do 2.) 
Hab. Sauvavor (coll. Solari: 2); Nicaragua, Chontales (Janson: 3 Q ). 
Four specimens, the three females narrower than the male, but apparently all 
belonging to the same species. From L. concinna (Lec.) the present insect may be 
known by its narrower form. 
21. Limnobaris pygmea, sp. n. 
Oblong-ovate, narrow, moderately shining, black, with a faint brassy lustre, almost glabrous. Head trans- 
versely grooved between the eyes; rostrum strongly arcuate, rather stout, a little longer than the 
prothorax, closely punctate, in the slightly longer and smoother. Prothorax transverse, rounded at 
the sides anteriorly, narrowed and feebly constricted in front ; closely punctate, except along the median 
line, Elytra depressed along the suture below the base, finely striate, the strie feebly punctate, the 
interstices flat. Prosternum unimpressed behind the transverse subapical groove, the latter shallowly 
foveate in the middle in the ¢. Metasternum at the apex and first ventral segment deeply sulcate in 
the g, the anterior tibiz strongly unguiculate in this sex. 
Length 13-2, breadth 4-3 millim. (do 9.) 
Hab. Mexico, Teapa (H. H. Smith); Guaremata, Chiacam and Tamahu in Vera Paz 
(Champion), Trece Aguas (Schwarz and Barber, in U.S. Nat. Mus.). 
Four males and four females. Darker and more convex than L. eneola and LL. eraria, 
the surface almost bare (above and beneath), the rostrum more curved, the ventral 
sulcus of the male long and deep. L. pygmea superficially resembles Cerpheres 
glabrescens (antea, p. 256), but the latter has a conical prothorax, relatively broader 
elytra, a deep prosternal sulcus extending backward between the coxe, &e. Li. (Baridius) 
Junerea, Kirsch, from Peru, is extremely like the present species, but it is more elongate, 
the prothorax is less transverse and more finely punctate, and the antennal club is 
longer. 
22. Limnobaris rufula, sp. n. (Tab. XVIII. figg. 7, 7a, ¢ ) 
5D°* 
Oblong-ovate, narrow, shining, rufescent, the head and prothorax piceous; glabrous above, subglabrous 
beneath. Head with a few minute punctures, transversely depressed between the eyes; rostrum about 
as long as the head and prothorax, curved, cylindrical, rather slender, sparsely, very finely punctate, the 
antenng inserted at the middle, the antennal club ovate. Prothorax transverse, narrowed and feebly
