CHALEPUS. | 55 
Head smooth, impunctate; front impressed with three short longitudinal grooves ; 
interocular space moderately produced. Antenne nearly half the length of the body, 
filiform, rather slender, slightly thickened towards the apex ; joints cylindrical, first and 
second short, equal, slightly thickened. Thorax rather broader than long, subconical ; 
sides converging from base to apex; transversely convex, transversely depressed on the 
hinder disc, closely punctured ; the hinder margin elevated. Elytra broader than the 
thorax ; sides parallel, very slightly enlarged towards the posterior angle ; apex obtusely 
rounded, outer margin nearly entire, obsoletely serrulate behind the middle and at the 
apex; each elytron with eight, at the extreme base with nine, rows of large, deep punc- 
tures; second, fourth, and sixth interspaces moderately costate. 
Resembles in coloration C. congener, but half the size, and rather less parallel in form, 
the elytra with an additional row of punctures at the base:

Head smooth, slightly produced between the eyes. Antenne nearly half the length 
of the body, slightly thickened towards the apex; joints cylindrical, the two lower 
ones short, nearly equal, the third distinctly longer. Thorax broader than long; sides 
obsoletely angulate, straight and parallel from the base to the middle, thence converging 
and slightly sinuate to the apex; anterior angle obliquely produced into a distinct 
subacute tooth ; transversely convex, faintly excavated transversely behind the middle, 
coarsely and closely foveolate-punctate, the punctures rather more distant on the medial 
— jine; the lateral margin, together with a broad discoidal vitta, black, the apical margin 
narrowly edged with piceous. Elytra rather broader than the thorax; sides parallel, 
very faintly constricted in the middle, obsoletely serrulate; apex regularly rounded, its 
serratures rather more distinct; each elytron with eight, at the extreme base with nine, 
rows of punctures; the second, fourth, and sixth interspaces costate.

parallelis, apice rotundatis, margine serrulatis; utrisque octo- basi nono-seriato-punctatis, interspatiis
