the largest of all, the eighth joint very minute, and the apical joint much acuminated. Thoraa short, 
shorter but broader than the head, widest near the base, deeply and closely punctured, with the interstices 
strongly alutaceous ; sides and front continuously rounded ; basal margin faintly sinuated, with the angles 
rounded. Scutellum rather small, triangular, deeply punctured. ilytra broader and one half longer than 
the head and thorax, widest before the middle, deeply and very closely punctured in almost straight 
transverse rows, the sides margined, the apex obtuse. Legs moderate, castaneous; tibize spinose, armed 
with spurs at the apex; anterior tarsi strongly dilated ( ¢?).

Body oval, rather narrow, moderately convex, pale castaneous, posteriorly piceous, densely clothed with golden 
pubescence. Head moderate, rather broad, deeply punctured, with the interstices alutaceous; eyes 
moderate ; antenne moderate, rufescent, with the apical joint pale. Zhorax small, broader but scarcely 
longer than the head, widest near the base, deeply and closely punctured in irregular transverse rows, 
with the interstices alutaceous ; sides rounded and margined ; basal margin faintly sinuated, with the angles 
obtuse. Scutellum moderate, triangular, deeply punctured. lytra rather long, posteriorly piceous, one 
half longer and rather broader than the head and thorax, widest near the middle, rather deeply and 
strigosely punctured in nearly straight transverse rows, the sutural stria moderate, the sides rather 
broadly margined, the apex obtuse. Legs moderate, rufescent ; tibi spinose. Underparts castaneous. 
Hab. GuatemMata, San Gerdnimo 3000 feet (Champion). 
This species appears to differ from C. terminans, Lec., in the rounded posterior angles 
of its thorax ; it is distinguished from others of the genus by its rather narrow form 
and semipiceous colour. 
PTOMAPHAGUS. 
Ptomaphagus, llliger, Kugel. Verz. Kif. Preuss. p. 84 (1798). 
Body oval or oblong, sometimes rather depressed, pubescent. Head not retractile, fitted by an abrupt ridge to 
the front of the pronotum, generally subtriangular. Thoraw often rather large, widest at the base, gene- 
rally transversely strigose. lytra more or less oblong, often partially truncate at the extremities, 
generally transversely strigose. Antenne moderate, sometimes rather short, gradually incrassated towards 
the apex ; 11-jointed, with the eighth joint much smaller than the seventh or ninth. Prosternum very 
short, scarcely enclosing the coxal cavities in front; episterna moderate ; epumera large, enclosing the 
coxal cavities behind; coxal cavities large, contingent. Mesosternuwm moderate, elevated between the 
coxal cavities; episterna large, humeral ; epimera short and very broad, reaching to the coxal cavities ; 
coxal cavities large, oval, and oblique, separated by the mesosternum. Metasternum moderate, not 
extending to the sides of the body ; episterna small, scarcely reaching the coxe ; epimera long, extending 
beyond the cox ; cox moderate, oval. Venter composed of six segments. Leys: anterior rather short, 
the tibie much dilated towards the apex, the tarsi dilated in the males; intermediate long, the tarsi 
slightly dilated in the males ; posterior long, the tarsi long and simple ; all the tarsi 5-jointed.
