484 STAPHYLINIDA, 
Four examples: the one obtained by Mr. Salvin is larger and more elongate than the 
others, and has a greater amount of punctuation on the head, but I think is certainly 
the same species as the smaller examples. 
24. Xantholinus crassiceps. 
Parallelus, nitidus, piceus; capite nigro; elytris fusco-testaceis, antennarum basi, palpis pedibusque rufis 
capite oblongo, utrinque dense fortiterque rugoso-punctato, angulis posterioribus minute subdentatis ; 
prothorace seriebus dorsalibus 4- vel 5-punctatis. 
Long. 7 millim. 
Hab. Mexico, Guanajuato (Sallé), Oaxaca, Cerro de Plumas (Hoge); GUATEMALA, 
Capetillo (Champion). 
This species is closely allied to X. attenuatus, Er., but is rather larger and broader, 
and hasa smaller number of punctures in the thoracic series ; from all the allied species 
in our fauna it may be distinguished by the structure of the head, the space at the sides 
under and behind the eye being unusually broad, very densely rugose-punctate, and 
enclosed by two lines meeting behind, and forming at their junction a very minute angle 
visible only in a certain light; the lower of these lines extends the greater part of the 
length of the head, while the upper is very obsolete, and in fact only definite quite 
near the hind angle; the punctuation on the upper surface of the head is coarser 
and closer than usual, and the smooth space on the middle large; the colour of the 
elytra and hind body vary somewhat; the former are, however, yellow, more or less 
clouded with piceous, and the latter has the sides of the segments near the base pallid 
to a greater or less extent. The prosternum is finely carinate along the middle. 
It is apparently rare, only seven examples having been procured, one of which is 
from Guatemala. 
25. Xantholinus eneotinctus. (Tab. XII. fig. 23.) 
Fuscus, supra sneus, nitidus; antennarum basi, pedibus palpisque rufis; capite subquadrato, versus latera 
fortiter punctato; prothorace parum punctato, seriebus dorsalibus irregularibus, circiter 8-punctatis ; 
elytris quam thorax paulo brevioribus, parce fortiter punctatis, nitidis. 
Long. 8 millim. 
Hab. Guatemata, San Isidro 1600 feet, El Tumbador 2500 feet, Zapote (Champion) ; 
Panama, David, Bugaba (Champion). 
Antenne stout, thicker externally, second and third joints moderately long, the latter 
evidently the longer. Head very shining, broadly impunctate on the disc, with rather 
coarse, not close, punctures on the sides. Thorax evidently narrowed behind, shining 
brassy, the punctures of the discoidal series irregular, especially on the basal portion, 
owing to some supernumerary punctures near the hind angles, and in addition with six 
or eight larger punctures on each side. Elytra quadrate, infuscate yellow, strongly 
tinctured with brassy, with numerous rather distant definite punctures.
