470 RHYNCHOPHORA. 
Guatemala city, Teapa, Atoyac, Higuito (Costa Rica), St. Vincent, &c., and these seem 
all referable to one variable species, with which B. corrusca, Boh., B. confinis, Lec., 
and B. manaquensis, Solari, may have to be included. B. erea is chiefly distinguishable 
by its small size, ovate or oblong-ovate shape, eneous, shining surface, and very short, 
stout, comparatively smooth rostrum ; the elytral interstices are finely seriate-punctate, 
the ninth raised towards the apex, the small setiform scales varying in size, and 
sometimes very minute or even wanting; and the legs and rostrum are often reddish. 
The rostrum varies in length, and the prothorax is often more rounded at the sides in 
the female than in the male. I have seen the types of B. corrusca, B. nicaraguensis, 
and B. managuensis, as well as various examples of B. wrea from Texas. The Costa 
Rican examples sent by Biolley, like those of B. setosella from the same locality 
(Higuito), were labelled as having been found on a Composite plant, Calea axillaris *. 
Two closely related S.-American forms have been described by Kirsch, the types of 
both of which have also been examined f.

Described from a single example, kindly communicated by Signor Solari. This is a 
form of B. wrea with the prothorax closely, coarsely punctate, and the elytral 
interstices somewhat coarsely uniseriate-punctate, the punctures each bearing a very 
minute scale. Some of our specimens from Guatemala city and Chilpancingo 
approach it very closely. 
28. Baris setosella. 
Baris setosella, Solari, Ann. Mus. Genova, xi. p. 418 (1906) '. 
Hab. Mexico (Truqui, in Mus. Brit.), Atoyac (H. H. Smith), Motzorongo (Osborn, 
in US. Nat. Mus.); Guaremata, San Gerénimo (Champion); Nicaragua, Managua 
(Solari!) ; Costa Rica, Higuito (Biolley). 
This is a form of B. wrea with the prothorax and elytral interstices densely 
punctured, the punctures on the elytra conspicuously setulose, the prothorax with a 
more or less distinct smooth median line. The second elytral interstice is confusedly 
punctured in the type and in several of the twelve specimens here referred to the same 
species.

+ B. erubescens, Kirsch, from Bogota, is a little more elongate than B. area, and has a slightly longer and 
stouter rostrum, a more convex prothorax, and deeply striate elytra, with the interstices coarsely uniseriate- 
punctate. B. enescens, Kirsch, from Peru, has scattered very minute punctures along the elytral interstices.
