238 RHYNCHOPHORA. 
Three examples. The two smaller have the front fringed with long, forwardly- 
directed, incurved, fulvous hairs, and the elytra more deeply impressed at the apex, so that 
the lateral callose elevations are more distinct ; they are probably females. The head 
is hidden in the larger specimen, but appears to be without the frontal hairs. In this 
species, as in P. poricollis and P. cacuminatus, certain of the elytral rows of punctures, 
notably the second, have three or four punctures displaced inwards, each opposite a 
puncture of the interstice on the outer side, so that the row appears to have its 
arrangement broken at intervals by the substitution of a pair of punctures for a single 
one. This is not found in P. amenus. 
‘ 4, Pityophthorus poricollis, sp. n. 
Oblongus, nitidus, subglaber, castaneus; prothorace amplo, latitudine longiore, anterius subconstricto, dorso 
haud gibboso, postice conferte fortiter punctato; elytris haud elongatis, ad suture apicem subproductis, 
sat fortiter punctatis, interstitiis rarius punctatis, declivitate utrinque sulcata. 
Long. 1:7 millim. 
Oblong, not elongate, shining and subglabrous, castaneous, the antenne and legs testaceous. Prothorax longer 
than broad, ample, slightly constricted in front, the apex rather obtusely rounded, the sides dilated behind 
the middle, the hind angles rectangular; surface ferruginous, with no median elevation or posterior 
depression, its apical half lighter, granulate, the granules forming concentric lines anteriorly and confused 
behind, its basal half closely and strongly punctured, with a shining non-elevated median line, the inter- 
spaces with a groundwork of minute punctures. Scutellum rounded-triangular. Elytra narrower than 
the prothorax and barely one-half longer, sides nearly straight, subampliated at the hinder third, then 
incurved, the apex acuminate and slightly produced at the sutural angles when seen from behind ; surface 
with rows of strong close punctures, the sutural row impressed, interstices narrow, not quite flat, with a 
few punctures as deep as those of the rows; apex strongly declivous, with a sulcus punctured in rows on 
each side of the suture, margins of the latter little elevated, finely tuberculate, the lateral calli rather 
strongly raised, tuberculate, sparsely setose. 
Hab. GuateMALa, Cerro Zunil (Champion). 
The head is too far concealed in the single specimen to allow of its structure being 
made out, but it is destitute of any frontal villosity. 
5. Pityophthorus cacuminatus, sp. n. 
Subelongatus, subnitidus, piceus aut piceo-ferrugineus, parce brevissime pilosus ; prothorace latitudine longiore, 
ante medium angustato, nec constricto, dorso postice sat fortiter punctato, linea media elevata levi; 
elytris ad apicem acuminatis, lineato-punctatis, declivitate obliqua, convexa, pube tenui vestita, utrinque 
preter suturam subsulcata. 
Long. 1°8 millim. 
Subelongate, moderately shining, pitchy or pitchy-red, with very short pubescence; the antenne and legs 
testaceous-yellow. Head (? 2) with a frontal impression margined with incurved pale yellow hairs. 
Prothorax longer than broad, nearly parallel-sided behind, narrowed anteriorly, the apex somewhat 
obtusely rounded, the hind angles rectangular; surface with a median transverse elevation, asperate in 
front, the asperities tending to form concentric lines, closely and strongly punctate behind, the median 
line subelevated, shining, narrow, widened at the base. Scutellum rounded. Elytra as wide at the base 
as the prothorax and three-fourths longer, the sides straight, parallel or very slightly divergent to the 
hinder fourth, then inflexed obliquely to the subproduced sutural angles; surface moderately strongly
