RHYNCHOPHORA. 
close rather fine granules, behind moderately shining, closely and rather strongly impunctate, the non- 
elevated median line and a spot on either side impunctate. Scutellum obtuse-triangular. LElytra scarcely 
so wide as the prothorax and a little more than one-half longer, parallel-sided, not narrowed behind and 
conjointly rounded at apex; regularly lineate-punctate, the sutural row impressed, the interstices flat, 
shining, and with fine seriate hairs towards the apex ; declivity convex, obsoletely punctate, with a hardly 
perceptible flattening and no sulcus on each side, the sutural margins subelevated. Underside lighter or 
darker fuscous, subglabrous. Antenne and legs yellowish. 
Hab. Mexico, Jalapa ({Hége) ; Guatemana, Capetillo (Champion). 
Three specimens from each locality. The examples from Jalapa are darker, with a 
more evident prothoracic constriction, and the rows of punctures on the elytra slightly 
stronger. The differences are probably not specific, but due to maturity. This species 
is superficially like Dryocetes macilentus, from which it is easily separated by the tibial 
structure. The lighter specimens somewhat resemble small examples of P. guate- 
malensis, a species also occurring at Capetillo, from which they may be distinguished 
by the absence of tubercles on the apex of the elytra. 
11. Pityophthorus cincinnatus, sp. n. 
Elongatus, subnitidus, pallide pilosus, niger, antennis pedibusque piceis ; prothorace longiore quam latiore, 
anterius confuse granulato, posterius tenuiter punctato; elytris ad apicem rotundatis, persubtiliter 
lineato-punctatis, interstitiis alutaceis, declivitate convexa, integra, impunctata, longius seriato-pilosa. 
Long. 2:2 millim. 
Elongate, not very shining, black, the antennee and legs piceous. Head (? 2) with an oblong shining space 
over the mouth, closely surrounded with a dense mass of curled yellow hairs, vertex granulate, mouth 
densely fringed ; antennal club large, oval. Prothorax longer than broad, widest at base, the sides very 
slightly curved and converging towards the apex, the latter rather obtuse in the middle; surface with a 
median, transverse, slight elevation, shortly pubescent, its anterior half granulate, its posterior half mode- 
rately closely and weakly punctured, except over the median line and two lateral spots. Scutellum 
rounded, shining, Hlytra as wide as the prothorax and two-thirds longer, parallel-sided, strongly rounded 
and not subacuminate at apex, with rows of very fine punctures, the sutural row scarcely impressed, 
interstices flat, finely alutaceous, set behind the middle with slender, pale, erect hairs in single rows ; 
declivity convex, not impressed nor punctate, with the suture just visibly elevated. Underside black. 
Legs piceous. 
Hab. GUATEMALA, Quiché Mts. (Champion). 
The solitary example received cannot be readily mistaken for any other Central- 
American species, save P. confinis, which it somewhat resembles. 
It is distinguished by the extremely fine punctuation and alutaceous insterstices of 
the elytra, and the pale erect pubescence of the declivity. The structure of the forehead 
is characteristic, at least for the sex to which the specimen described belongs. 
12. Pityophthorus obsoletus, sp. n. 
Oblongus, subnitidus, glaber, piceo-fuscus, subtus piceus, antennis, coxis pedibusque testaceis; clava antennarum 
angusta; prothorace semielliptico, antice confuse granulato, postice sat subtiliter punctato, linea media 
levi; elytris quam subtilissime lineato-punctatis, interstitiis coriaceo-rugulosis, declivitate convexa, integra. 
Long. 1°5 millim. 
Oblong, not elongate, slightly shining, glabrous above, piceous-brown, the antenne, coxe, and legs pale 
testaceous. Front with an impression margined by a forwardly directed fringe of pale hairs. Antennal
