424 . RHYNCHOPHORA. 
Hab. Mexico, Guanajuato (Sallé), Amula in Guerrero (H. H. Smith), Cuernavaca 
in Morelos (Wickham ; Barrett, in U.S. Nat. Mus.). 
Seventeen specimens, varying greatly in size. The elongate, subcylindrical shape, 
the long basal joint of the funiculus, and the immaculate elytra readily distinguish 
T. perlonga. 
2. Trepobaris inornata, sp. n. 
Elongate-ovate, narrow, shining, black ; glabrous above, the punctures on the under surface and legs each 
bearing a minute hair-like white scale. Head and rostrum as in 7’. perlonga, the funiculus with joint 1 
about as long as 2-4 united. Prothorax nearly as long as broad, convex, very gradually narrowing 
from near the base, feebly constricted in front; coarsely, closely punctate. Elytra moderately long, very 
gradually narrowing from the rounded humeri; sharply striate, the interstices flat, each with a regular 
row of fine scattered punctures, 3 not dilated at the base, 9 raised posteriorly. Anterior femora with 
a small tooth. First ventral segment slightly hollowed down the middle, and the anterior tibia with 
the apical uncus elongated, in the ¢. 
Length 3-4,4,, breadth 1;4,-1? millim. (¢ 9.) 
Hab. Mexico, Chilpancingo and Tepetlapa in Guerrero (H. H. Smith), Matamoros 
Izucar in Puebla (Hége), Puente de Ixtla ( Wickham). 
Found in numbers at Chilpancingo and Puente de Ixtla. Less elongate and less 
cylindrical than 7. perlonga, the basal joint of the funiculus relatively shorter, the 
interstitial series of punctures in the elytra finer and more scattered. 
3. Trepobaris elongata. 
Trepobaris elongata, Casey, Ann. N. York Acad. Sci. vii. p. 519°. 
Hab. Norra America, ‘Texas 1.—Mexico, Monterey in Nuevo Leon (Hoge). 
One male, agreeing perfectly with a Texan specimen communicated by the 
Smithsonian Institution, both insects having a few white scales at the base of the 
third elytral interstice. Casey’s description was taken from a single male example. 
The apical uncus of the anterior tibia is about equal in length in the two sexes, 
4. Trepobaris yucatana, sp. n. 
Oblong-ovate, rather narrow, shining, black; the elytra with a few small white scales at the base of the 
third interstice, the punctures of the under surface and legs each bearing a minute hair-like whitish 
scale. Head finely punctate, transversely grooved between the eyes ; rostrum abruptly bowed from the 
base, moderately stout, a little longer than the prothorax, sparsely, finely punctate. Prothorax broader 
than long, feebly constricted in front, the sides rounded anteriorly and subparallel behind ; closely, 
moderately coarsely punctate, except along the smooth median line. Elytra slightly wider than the 
prothorax, gradually narrowing from the rounded humeri; with deep, feebly punctured strie, the 
interstices flat, regularly uniseriate-punctate, 3 slightly widened at the base. Pygidium closely punctate, 
large and somewhat convex in the ¢, smaller and vertical in the 9. Beneath closely, the abdomen 
more sparsely, punctate; ventral segment 1 shallowly suleate in the g. Prosternal sulcus narrow, 
deep. Femora unarmed. Anterior tibie with the apical uncus elongated in the ¢. 
Length 33-4, breadth 12-1,% millim. (¢ 9.)
