LIMNOBARIS. | 347 
prosternal spines, is very like an unnamed example from New Jersey sent me by 
Mr. Wickham, the other, labelled as from ‘“‘ Panama,” having very long spines, much as 
in a male from Florida sent me by the U.S. Nat. Museum; the female from “ Mexico ” 
has the prothorax more parallel-sided than the one from Costa Rica. They all have 
the upper surface finely alutaceous and rather dull, the prothorax closely and finely 
punctate, except along the narrow smooth median space, the vestiture sparse and very 
fine, and the interstitial puncturing of the elytra close, confused towards the base. 
6. Limnobaris evanescens, sp. n. 
Oblong-ovate, rather narrow, shining, black, the legs partly or entirely piceous ; the punctures at the sides of 
the prothorax and those along the elytral interstices each bearing a minute, hair-like, whitish scale, the 
under surface and legs also clothed with similar scales. Head with minute scattered punctures, trans- 
versely grooved between the eyes ; rostrum arcuate, about as long as the head and prothorax, in the ¢ 
thickened towards the base and closely punctate, in the @ smoother, more slender, and subcylindrical ; 
antennal club ovate. Prothorax transverse, rounded at the sides anteriorly, narrowed and feebly 
constricted in front; closely, coarsely punctate, except along a narrow space down the middle. Scutellum 
- subquadrate. Elytra a little wider than the prothorax, narrowing from about the basal third; deeply 
striate, the stria feebly punctate, the interstices flat and each with a row of minute scattered punctures. 
Beneath closely punctate. Anterior coxse separated by a little less than their own width. 
$. Prosternum armed with two short spines or conical tubercles, and with a very deep or shallower circular 
excavation between them ; first ventral segment deeply excavate down the middle. 
Q. Prosternum shallowly foveate in the middle in front, the intercoxal portion triangular and slightly 
hollowed. 
Length 23-3, breadth 14-13 millim. (¢ @.) 
Hab. Mexico, Cordova, Toxpam (Sallé), Orizaba (Osborn, in U.S. Nat. Mus.; H. H. 
Smith), Teapa (H. H. Snmvth); GUATEMALA, Purula, Panima, Tamahu, and Chiacam in 
Vera Paz (Champion); Nicaracva, Chontales (Janson); Costa Rica, San José (Knad, 
in U.S. Nat. Mus.). 
Found in numbers at Purula. The minute, uniseriately-arranged, scattered punctures 
of the elytral interstices, the coarsely-punctate prothorax, and the shining upper 
surface chiefly distinguish this species. The prosternal spines vary in length, but are 
never very long. 
7, Limnobaris alutacea, sp. n. 
Oblong-ovate, finely alutaceous, rather dull, black, the antenne and tarsi fusco-ferruginous; the under 
surface, the sides of the prothorax, and the legs somewhat thickly clothed with small, hair-like, white 
scales, the seriate punctures along the elytral interstices also each bearing a very minute white scale. 
Head transversely grooved and obsoletely foveate between the eyes; rostrum arcuate, moderately stout, 
about as long as the head and prothorax and somewhat thickly punctate in the ¢, a little longer, 
smoother, and more slender in the @. Prothorax much broader than long, narrowed and feebly 
constricted in front ; coarsely, closely punctate, except along a narrow space down the middle. Elytra 
a little wider than the prothorax, subparallel for a short distance below the somewhat prominent 
humeri ; punctato-sulcate, the interstices flat and conspicuously uniseriate-punctate from the base to the 
apex. Beneath coarsely and densely, the median portion of the ventral segments’ more finely and 
sparsely, punctate. Anterior coxee separated by a little less than their own width.
