ture of the elytra is subgranulated; shoulders rounded, not prominent, sides straight 
and slightly margined ; apex somewhat obliquely truncate; sutural apical angles right- 
angled, exterior apical angles rounded. Abdomen faintly punctate; fimbriæ raised and 
prominent. Legs testaceous. 
From Panama. I owe this well-marked species to the kindness of M. de Motschulsky.

Section ANGUSTE-FIMBRIATA. 
Abdomen fimbriis angustatis vel vix perspicuis. Elytra haud striata*. 
Genus CTILODES (xridoc, a ram (battering-ram) ; eidoc, appearance). 
Caput oculis haud basin attingentibus; epistomate protenso, medio profunde excavato; sulcis antennariis 
convergentibus. Labrum bifidum, membranaceum, barbatum, elongatum.  Mandibule magne, apice 
bicuspidate, interne dentate. Abdomen fere sine fimbriis ; segmentis ultimis duobus expositis ; 
secundo et tertio brevioribus. 
Large, subcylindrical, oblong-ovate, irregularly punctate. Head large, broad, and 
when at rest dependent. Eyes not large, not projecting, and not reaching to the base of 
the head.  Epistome conical and projecting, but at the point deeply excavated, leaving a 
* But for some exceptional species in the previous section, I should have added the presence or absence of striæ on 
the elytra to the breadth of the fimbrie as a character for separating the sections. The whole of the Anguste- 
fimbriata (with the exception of those I have placed as transitional genera) have the elytra without stris. The whole 
of the Late-fimbriata (with the exception of a few Colasti) have them more or less distinctly striated.
