PITYOPHTHORUS. 237 
pubescence finer, scantier, and shorter. Whether an example of P. nitidulus before 
me so named by Eichhoff himself is actually Mannerheim’s species or not, I have no 
means of deciding. 
2. Pityophthorus ameenus, sp. n. 
Subcylindricus, sat nitidus, badius; subtus cum antennis pedibusque testaceus; prothorace latitudine sub- 
longiore, antice subconstricto, dorso anterius granulis in lineas concentricas ordinatis aspero, posterius 
fortiter sparsim punctato, linea media nitida levi; elytris posterius setosis, acuminatis, ad amussim 
striato-punctatis, interstitiis levibus, declivitate utrinque preter suturam impressa, levi, margine utroque 
suturali et callo laterali elevatis, subtiliter tuberculatis. 
Long. 2-2 millim. 
Nearly cylindrical, bright brown, the apex of the prothorax a little darker, the underside, antenne, and legs 
testaceous. Front (@ ?) covered with short, downy, erect hairs; eyes emarginate. Prothorax a little 
longer than broad, widest before the base, slightly constricted in front, the sides behind gently, the apex 
broadly rounded, the hind angles obtuse; dise with a slight median elevation, in front with irregular 
concentric rows of granules, behind subdepressed, somewhat dull, rather strongly and sparingly punctured, 
the median line and two lateral spots impunctate, shining. Scutellum small, obtuse triangular. Llytra 
narrower at the base than the prothorax at its widest and two-thirds longer, the shoulders slightly obtuse 
but not rounded, the sides subparallel, obliquely rounded at the acuminate apex; surface with quite 
regular rows of strong punctures, the sutural row distinctly, the others weakly impressed, interstices 
nearly flat, shining, impunctate ; declivity with a moderately deep, wide, shining, impunctate impression 
along each side of the suture, the margins of the latter and the lateral calli elevated, finely tuberculate, 
the ridge and outer face of the calli pilose with rather long hairs. 
Hab. Guatemata, Duefias (Champion). 
One specimen ; distinguished from the N.-American P. pullus (Zimm.) (=cribripennis, 
Eichh.) by the very regular rows of punctures on the elytra and the shining smooth 
interstices. In other respects it somewhat resembles that species. 
3. Pityophthorus confusus, sp. n. 
Subelongatus, cylindricus, sat nitidus, fusco-ferrugineus, pube brevi tenui vestitus; prothorace fere semielliptico, 
apice medio obtusius rotundato, dorso post medium fortiter punctato, linea media levi; elytris ad apicem 
acuminatis, lineato-punctatis, lineis internis irregulariter compositis ; declivitate preter suturam utrinque 
impressa, impunctata, lateribus elevatis vix callosis, 
“Long. 2°2-2°8 millim. 
Subelongate, cylindrical, moderately shining, ferruginows, prothorax a little infuscate apically; pubescence 
fine, very short, and confined to the extremities of the body. Prothorax longer than broad, widest at 
pase, the sides very slightly rounded behind, gradually more strongly towards the apex, which is some- 
what obtuse in the middle, hind angles rounded, base truncate; surface with a slight median elevation, 
irregularly asperate in front, strongly but not closely punctured behind, except over the median line, 
with an interstitial punctuation of minute points. Scutellum rounded, punctured. Elytra as wide as 
the prothorax and one-half longer, the shoulders rectangular, the sides parallel, the apex acuminate, 
slightly produced at the sutural angles, with rows of strong punctures, the second and third irregular, 
the sutural row not impressed, interstices flat, with a few punctures scarcely distinguishable from those 
ef the strie, closer posteriorly ; apex strongly but obliquely declivous, with an impunctate impression on 
each side of the suture, the margins of which are elevated, but not conspicuously tuberculate. Underside 
scarcely pubescent, the fifth ventral segment deeply incised at apex. 
Hab. Guatemata, San Gerénimo (Champion).
