longer than the second. Thorax about one third broader than long; sides nearly 
straight and parallel from the base to the middle, thence obliquely converging to. the 
apex; anterior angle armed with a very short obtuse tooth; above subcylindrical, 
closely covered with large foveolate punctures, the hinder disc flattened ; upper surface, 
together with the sides beneath, fulvous; the apical and lateral margins, together with 
the basal lobe, narrowly edged with piceous. Elytra parallel, rounded at the apex, 
finely serrulate, the apical serratures not coarser than those on the lateral margin ; each 
elytron with ten rows of large deeply impressed round punctures, the rows entire ; 
second, fourth, and eighth interspaces, together with the suture, strongly costate ; 
the sixth interspace below its middle also raised, but much less distinctly so than the 
others; middle disc covered with a broad fulvous vitta, which extends downwards from 
the basal margin to the middle of the elytra. |

Elongatus, parallelus, niger, nitidus, femoribus basi flavis; thorace transverso, lateribus angulatis; dorso 
transversim convexo, pone medium transversim excavato, fortiter punctato; lateribus vittaque discoidali 
nigris; elytris parallelis, apice regulariter rotundatis, margine minute serrulatis ; utrisque decem-sefiato-

Front impressed with a broad longitudinal fovea; interocular space moderately 
produced, its apex angulate, a small patch above the antenne obscure rufo-piceous. 
Antenne rather more than one third the length of the body, slightly thickened towards 
the apex, joints cylindrical. ‘Thorax transverse; sides angulate, straight and parallel 
behind the middle, thence obliquely converging and faintly sinuate to the apex; anterior 
angle armed laterally with a small subacute tooth ; upper surface subcylindrical, rather 
deeply excavated transversely on the hinder disc, strongly and deeply punctured. 
Elytra parallel, regularly rounded at the apex, outer margin very finely serrulate ; each 
elytron with ten rows of punctures, the second and fourth interspaces rather strongly, 
the eighth less distinctly, costate. 
46. Chalepus amiculus. 
Angustatus, elongatus, subcylindricus, nitidus ; subtus niger, femoribus anticis basi fulvis; supra fulvus, scutello 
capiteque nigris, hoc macula parva inter oculos fulva; thorace transverso, lateribus rotundatis, ante 
medium sinuatis, ad apicem constrictis; crebre foveolato-punctato, lateribus vittaque lata discoidali nigris ; 
elytris parallelis, lateribus obsolete serrulatis, apice rotundatis, distincte denticulatis; utrisque decem- 
seriato-punctatis; interspatiis secundo, quarto, sexto et octavo costatis; vitta suturali vix ante apicem 
abbreviata, nec non linea marginali, a basi ultra medium extensa, nigris,
