456 RHYNCHOPHORA. 
19. Pseudobaris atitlana, sp. n. (Tab. XXI. figg. 17, 174, 6, 3.) 
3. Oblong-ovate, very shining, black, the elytra with a small spot ef white scales at the base of the third 
insterstice, the punctures of the under surface and legs each bearing a minute white scale. Head finely 
punctate, transversely depressed between the eyes ; rostrum strongly arcuate, about as long as the head 
and prothorax, stout, slightly flattened at the tip, closely, rather coarsely punctate. Prothorax conical, 
constricted in front, sparsely, finely punctate, smooth along the median line. Scutellum transverse, 
smooth, flat. Elytra somewhat undulate, with rows of small oblong punctures placed in fine strix, the 
first and second strie becoming almost obsolete at the base, the interstices broad, flat, narrowly costate 
on the apical declivity, each with a row of excessively minute punctures. Beneath very coarsely, the 
abdomen sparsely and finely, punctate. Prosternum with the median sulcus abruptly terminating 
between the coxee, the basal process flat, broadly emarginate behind (fig. 176). Anterior femora with a 
blunt tooth, the others obsoletely serrulate. Anterior tibie strongly sinuate within, the uncus stout. 
Length 4, breadth 2 millim. 
flab. GUATEMALA, Panajachel 5000 feet (Champion). 
One male, found, in Dec. 1880, in the arid district bordering the Lake of Atitlan. 
Very like P. oscillans, differing from it in the much more distinctly punctate elytral 
strie, the smooth, flat scutellum, the emarginate basal process of the prosternum, the 
strongly sinuate anterior tibie, and the less cylindrical rostrum (¢), the anterior 
femora with one small tooth only, and the others obsoletely serrulate. 
20. Pseudobaris biolleyi, sp. n. 
3. Oblong-ovate, very shining, black; the third elytral interstice with a few narrow whitish scales at the 
base, the punctures on the under surface and legs each bearing a minute scale. Head closely punctate, 
transversely depressed between the eyes; rostrum arcuate, about as long as the head and prothorax, 
rather slender, finely punctate, the antenne inserted at the middle. Prothorax somewhat convex, much 
broader than long, strongly constricted in front, the sides rounded anteriorly ; sparsely, finely punctate; 
except along the smooth median line. Elytra oblong-subtriangular, undulate ; finely striate, the strie 
distinctly punctate at the base, the interstices broad, flat, narrowly costate at the apex, each with a row 
of scattered very minute punctures, the third with several additional impressions at the base. Beneath 
coarsely, the abdomen finely, punctate ; fifth ventral segment shallowly foveate at the apex. Prosternal 
sulcus shallow, not margined. Legs rather long and slender; anterior femora with a distinct tooth, the 
others obsoletely dentate, the posterior pair shallowly sulcate in their outer half; anterior tibie with a 
long apical uncus. 
Length 34, breadth 12 millim. 
Hab. Cosra Rica, Guatuso near Cartago 1500 metres (Biolley). 
One male. Not unlike P. atitlana, but with the prothorax shorter and more 
constricted in front, the rostrum more slender and subcylindrical, the elytra undulate 
and more deeply striate, the prosternal sulcus shallow, &c. The posterior femora have 
a shallow sulcus beneath, the others being excavate at the apex only. 
. 21. Pseudobaris dentipes, sp.n. (Tab. XXI. fige. 18, 18a, ¢.) 
Oblong, shining, black; the elytra with a dense oblong patch of narrow yellowish-white scales at the base, 
the rest of the upper surface almost bare, the punctures on the under surface and legs each bearing a 
small whitish scale. Head closely punctate, transversely depressed and foveate between the eyes; 
rostrum stout, arcuate, a little longer than the prothorax, densely, rugosely punctate, much smooth
