348 RHYNCHOPHORA. 
‘3. Prosternum armed with two short spines, and with a shallow excavation between them ; first ventral 
segment excavate down the middle. 
Length 3-34, breadth 14-13 millim. (¢ 9.) 
Hab. Mexico, Mexico city (Hoge). 
Four females and one male, the latter with the apex of the abdomen somewhat 
dragged out and the pygidium, in consequence, visible*, Longer and duller than 
L. evanescens, the elytra more parallel-sided and with the interstices rather coarsely 
uniseriate-punctate, the sides of the body beneath more coarsely and more densely 
punctate. L. puteifer, Casey, from Indiana, is probably a near ally of the present 
insect. - 
8. Limnobaris angustata, sp. n. 
Oblong-ovate, narrow, somewhat depressed above, black, with a faintly brassy lustre, the antenna, prosternal 
spines, knees, and tarsi obscure ferruginous ; the elytral interstices each with a dense line of rather 
coarse, hair-like, whitish scales, the sides of the prothorax, legs, and under surface also clothed with 
minute similar scales. Head transversely grooved between the eyes ; rostrum about as long as the head 
and prothorax, curved, cylindrical, closely punctate, striate at the base, smoother and more slender in 
the 2. Prothorax transverse, closely, finely punctate, except along a narrow space down the ntiddle. 
Elytra deeply striate, the interstices each with a single row of minute, closely-placed punctures. 
Beneath closely punctate. Anterior coxe separated by a little less than their own width. 
¢. Prosternum armed with two short spines, and with a deep excavation between them; first ventral 
segment depressed down the middle. 
Length 23, breadth 1,1, millim. (¢ @.) 
Hab. Mexico, Vera Cruz (H. H. Smith). 
One pair. Smaller and narrower than L. confusa, the elytra more shining and with 
the vestiture coarser. From the N.-American LZ. concinna (Lec.) it may be separated 
by its less parallel form and the more closely uniseriately-arranged vestiture of the 
elytra. 
9. Limnobaris dentifer, sp.n. (Tab. XVIL. figg. 35, 35a, b, ¢.) 
Oblong, flattened above, shining, piceous, the rostrum, antenne, prosternal spines, and legs obscure ferruginous ; 
the elytral interstices each with a line, becoming double at the base, of fine, hair-like, yellowish-white scales, 
the sides of the prothorax, under surface, and legs sparsely clothed with similar scales. Head closely, 
very finely punctate, transversely grooved between the eyes; rostrum a little longer than the head and 
prothorax, curved, slender, striate, and feebly punctate, the antenne inserted behind the middle, the 
club ovate. Prothorax nearly as long as broad, feebly constricted and narrowed in front ; closely 
punctate, obsoletely granulate at the sides, the disc without definite smooth median space. Scutellum 
trapezoidal. LElytra oblong, very little wider than the prothorax ; deeply striate, the interstices minutely 
nniseriate-punctate and somewhat concave. Beneath closely, the inter- and post-coxal portions of the 
prosternum sparsely and more coarsely, punctate, the anterior portion of the latter smooth. Prosternum 
tumid, unimpressed, armed with two moderately long spines and dilated behind the widely-separated 
anterior coxee. Legs rather stout; tibia widening from the base, the anterior pair (fig. 35 5) broad and 
* As in Boheman’s type of Cenérinus confusus.
