BARIS.—ERACHYBARIS. ATS 
84. Baris rubicundula, sp.n. (Tab. XXII. figg. 27, 27 a.) 
Oblong, narrow, convex, shining, piceous, the elytra and legs rufessent ; almost glabrous above, the punctures 
at the sides of the prothorax and on the under surface and legs each bearing a very minute scale. Head 
sparsely, minutely punctate, with a smooth, shallow, transverse groove between the eyes; rostrum curved, 
very stout, about as long as the prothorax, slightly widened towards the tip, sparsely, finely punctate. 
Prothorax transverse, distinctly narrowed behind, the sides gradually and obliquely converging forwards 
to the constricted apical portion ; closely punctate, with indications of a smooth median line. Scutellum 
small, transverse. Elytra a little wider than the prothorax, subparailel in their basal half and arcuately 
narrowing thence to the apex, the humeri obtuse; sharply and narrowly punctate-striate, the interstices 
broad and flat on the disc, narrowly costate at the apex, each with a row of extremely minute scattered 
punctures. Pygidium short, vertical. Beneath closely, the abdomen more sparsely and finely, punctate. 
Prosternum unimpressed behind the transverse subapical groove. Anterior cox rather small, separated 
by a little more than their own width. Legs short ; tibixe almost straight, the anterior pair with a short 
tooth at the inner apical angle; tarsal claws very small, free. 
Length 24, breadth 1, millim. (@ ?) 
Hab. British Honpuras, Rio Hondo (Llancaneaua). 
One specimen. A small, narrow, convex, rufescent form, with the upper surface 
polished and almost glabrous, the prothorax distinctly narrowed at the base, the 
elytral interstices narrowly costate at the apex, the pygidium very short. It is not 
closely related to any of the other species here described, and bears a certain resemblance 
to the N.-American lesiobaris albilatus, Lec. 
BRACHYBARIS. 
Brachybaris, Faust, Deutsche ent. Zeitschr. 1886, p. 3871. 
This genus includes a small, short-ovate, compact, eneo-piceous form, with the 
prothorax margined at the sides *, and deeply excavate and smooth on the flanks, the 
rostrum stout and extremely short, the basal joint of the antennal club shining, the 
eyes very large and almost contiguous beneath, the anterior tibize bi-unguiculate in the 
male (fig. 28 0) and uni-unguiculate in the female, the prosternum shallowly sulcate, 
the tarsal claws minute and free, the pygidium very large and oblique in the male, 
smaller, transverse, and convex in the female.

Hab. Mexico? (Truqui, in Mus. Brit.), Ventanas in Durango (Hoge: ¢ ?); Britis 
Honpuras, Rio Hondo (Blancaneaua); Nicaragua, Chinandega (Baker: ¢ 2 ).— 
CoLomBIa ?. 
We hare received six examples of this species, agreeing with the types of Boheman 
* Baridius thoracicus, Kirsch, from Peru, has a somewhat similarly margined prothorax, but in that insect 
the pygidium is covered by the elytra, &c.; it will probably have to form the type of a uew genus of 
“ Centrinides.”
