428 RHYNCHOPHORA. 
2. Pseudobaris disparilis, sp. n. (Tab. XXI. figg. 4, 44, 2.) 
Oblong-ovate, very shining, black ; the elytra with a small, oblong patch of narrow white scales on the 4th 
interstice at a little beyond the middle and sometimes a few white scales at the base of the 2nd, the 
punctures of the legs and under surface each bearing a minute hair-like white scale. Head finely 
punctate, the frons depressed or with a shallow longitudinal groove; rostrum (¢) arcuate, moderately 
stout, about as long as the head and prothorax, finely punctate, (2 ) smoother, more slender, and greatly 
elongated, reaching the middle of the metasternum, the antenne inserted at about the basal third in the 
@ and towards the middle in-the ¢., the funiculus rather slender, the club ovate. Prothorax subconical, 
constricted in front; very sparsely, finely punctate. Elytra transversely flattened or depressed at and 
below the base, with feebly punctured, sharp, narrow striz, the interstices broad, almost smooth and 
flat, the 2nd slightly widened at the base. Beneath coarsely, the abdomen very sparsely and finely, 
punctate. Prosternum deeply sulcate, tha basal process margined laterally and truncate or feebly 
emarginate behind. Anterior coxe separated by considerably less than their own width. Femora 
unarmed. . 
Length 53-6, breadth 22-3 millim. (¢ 2.) 
Hab. Mexico, Toxpam and Playa Vicente in Vera Cruz (Sal/é). 
‘Two males and three females, the sexes labelled as distinct species in the Sallé 
collection. Smaller than P. diguttata, the elytra sharply striate throughout, the pro- 
sternal process less developed and truncate or feebly emarginate behind, the funiculus 
not so stout, the antennal club ovate, the rostrum greatly elongated in the female. 
8. Pseudobaris sexguttata, sp.n. (Tab. XXI. fige. 5,5, 2.) 
Subovate, very shining, black ; the elytra each with three small dense patches of narrow white scales—one 
at the base of the 2nd interstice, another at the base of the 6th, and one on the 4th at a little beyond 
the middle,—and sometimes two or three similar scales on the 6th in a line with those on the 4th; the 
punctures on the under surface and legs each bearing a white scale, those on the sternal side-pieces oval 
in shape. Head closely punctate, transversely depressed between the eyes; rostrum strongly arcuate, 
stout, nearly as long as the head and prothorax, closely punctate, smoother at the tip in the 9. Pro- 
thorax transverse, rapidly narrowed from the base, strongly constricted in front; sparsely, coarsely 
punctate, the disc sometimes with a few widely scattered minute punctures only. Elytra rounded- 
triangular, depressed along the suture, with sharply cut, feebly punctured striae, the interstices broad, 
flat, and almost smooth (except upon the squamose spots). Beneath very coarsely, the abdomen finely, 
punctate. Prosternum deeply sulcate, the basal process with a very prorainent, cariniform ridge on 
each side, hollowed within, and slightly emarginate behind. Anterior cox separated by considerably 
less than their own width. Legs short; femora unarmed. 
Length 22—4, breadth 1j-2,1, millim. (¢ 2.) 
Hab. Mexico, Santa Lucrecia in Vera Cruz (Knadb, in U.S. Nat. Mus.), Jalapa 
(Smith, ex Wickham); GuateMALA, Cahabon, Cerro Zunil (Champion); Nicaragua, 
Ometepe 4000 feet (Shimek, ex Wickham), Chontales (Janson), Managua (Solari) ; 
Panama, Volcan de Chiriqui, Bugaba (Champion). 
Kleven specimens, varying greatly in size, and in the puncturing of the prothorax, 
the disc (except along the basal margin) being sometimes almost smooth. P. ser- 
guttata is readily distinguished by the three sharply-defined white spots on each 
elytron and its subovate shape. The coarse punctures on the under surface each bear 
a rather large oblong white scale. The rostrum is of about the same length in the 
two sexes.
