XANTHOLINUS., ATT 
5, Xantholinus oculatus. 
Nitidus, rufus ; capite nigro, abdominis segmentis 3°-6™ late nigricantibus; capite punctis impressis tantum 
paucis; prothorace absque seriebus dorsalibus, utrinque versus marginem anteriorem punctis duobus ; 
elytris sublevigatis serie discoidali punctorum majorum. 
Long. 11 millim. 
Hab. Nicaracua, Chontales (Janson). 
Head narrowed in front, with large and rather prominent eyes, with only a very few 
punctures, one on each side between the eye and the termination of the frontal furrows, 
one or two just behind the eye, and some others about the vertex. Thorax very 
slightly narrowed behind, of a shining red colour; the only punctures it bears in addition 
to those at the margins are two on each side placed transversely near the front. Elytra 
rather longer than the thorax, pale red, shining, only obsoletely punctured, but with a 
distinct discoidal series of about six distant punctures, and a more indistinct sutural 
series. Hind body with the base red and the extremity broadly yellow, the intervening 
segments being blackish, their margins, however, remaining red. 
6. Xantholinus levipennis. 
Rufus, capite abdomineque nigris, hoc apice pedibusque flavis, pronoto piceo ; capite angusto, punctis impressis 
perpaucis ; prothorace absque seriebus dorsalibus, utrinque prope latus puncto singulo, et versus marginem 
anteriorem punctis duobus transversim positis ; elytris sublevigatis, seriebus discoidalibus et suturalibus 
tantum distinctis. 
Long. 10 millim. 
Hab. Mexico, Tuxtla (Sal/é). 
Head rather narrow, with large and rather prominent eyes, and with very few 
punctures, but with an oblique groove on each side at the margin of the eye. 
This species is similar to X. oculatus; but in addition to the dark pronotum it is 
distinguished by the narrower form, and the head being more distinctly quadrisulcate. 
Only one badly-preserved example is known to me. 
7. Xantholinus rudis. (Tab. XII. fig. 21.) 
Niger, nitidus ; elytris, pectore pedibusque rufis, antennis rufo-obscuris, basi picea; capite fortiter punctato, 
medio levigato; elytris seriebus dorsalibus irregularibus 10—12-punctatis, lateribus crebre irregulariter 
punctatis. 
Long. 12 millim. 
Hab. GuareMAaLa, near the city, San Gerénimo, Mirandilla 1700 feet ( Champion). 
Allied to X. pectoralis, Er., but readily distinguished by the more numerous punc- 
tuation of the thorax. The head is a good deal narrowed in front, with rather 
numerous moderately coarse punctures that are wanting on the middle. The thorax is 
a little narrowed behind, its punctures are coarse, and in addition to those of the dorsal 
series there are about twenty others on each side. ‘The elytra are as long as the thorax, 
coarsely punctate; the hind body is sparingly but distinctly punctate and pubescent.
