I have seen thirteen specimens of this species, including the type, all but one being 
from Mexico. It is an oblong, shining, black or eneous form, with numerous rather 
coarse, decumbent, whitish sete on the elytra, in addition to the white spot at the 
base. The elytral interstices are less coarsely and more sparsely punctured than in 
P. cribripennis, the second and third relatively wider and with an irregular double 
series of impressions. The rostrum is very stout, arcuate, and about as long as the 
head and prothorax in both sexes. The prosternal sulcus is straight, shallow, and 
margined at the sides. 
25. Pseudobaris binotata, sp.n. (Tab. XXI. figg. 21, 21a, ¢.) 
Oblong-ovate, convex, shining, black; the elytra with a dense oval patch of narrow white scales at the base 
of the third interstice and several widely scattered decumbent white setz along the interstices 3, 5, 7, 
and 9; the punctures of the under surface and legs each bearing a small white hair-like scale. Head 
closely punctate, transversely depressed between the eyes; rostrum stout, arcuate, a little longer than 
the prothorax, closely punctate, smoother towards the apex in the 2, the antenne inserted at the 
middle. Prothorax transverse, rounded at the sides anteriorly, feebly constricted in front; coarsely, 
closely punctate. Elytra rather short, narrowly punctate-striate, the interstices broad, flat, subcostate 
at the apex, each with a closely-packed row of moderately coarse transverse punctures, 3 widened at the 
base. Beneath closely punctate. Prosternal sulcus deep, straight. Femora unarmed. 
Length 23-3, breadth 1,,-14. (¢ 2.) 
Hab. GuateMaLa, Cahabon in Vera Paz (Champion: 3 2); Panama, Taboga I. 
(Champion: @) 
Three specimens. Very like the smaller specimens of P. cribripennis, but more 
convex, the white patch at the base of the third interstice larger, the scattered sete 
on the alternate interstices finer and less elongate. More convex than P. cylindricollis, 
the prothorax arcuately narrowing from near the base, the anterior femora unarmed.
