Chalepus chromaticus (pp. 70, 121). | 
To the Mexican localities given, add :—Atoyac in Vera Cruz (Z. A. Smith). 
Chalepus propinquus (p. 71). 
To the localities given, add :—Mexico, Teapa in Tabasco (#. H. Smith). 
Three specimens. 
Chalepus angulosus (pp. 73, 121). 
To the localities given, add: —Mzxico, Teapa in Tabasco (H. H. Smith); GUATEMALA, 
Panzos (Champion). | | 
Chalepus subhumeralis (p. 74). 
To the localities given, add:—Mexico, Atoyac in Vera Cruz, Teapa in Tabasco 
(Hl. H. Smith). 
45 (a). Chalepus maculicollis. | 
Elongate, rather narrow, subparallel, slightly shining; black, the prothorax with an oblong fulvous vitta on - 
either side; the legs and antenne black. Head subopaque, almost smooth; the front moderately 
produced, the interocular space longitudinally grooved in the middle behind, feebly carinate anteriorly, 
and with a short shallow groove on either side. Antenne short, not one third the length of the body, 
thickening outwardly ; the joints cylindrical, 3 a little longer than 2 and much shorter than 4, 4 and 5 
about as broad as long, 6-10 transverse, 11 much longer than 10, acuminate. Prothorax strongly trans- 
verse, convex, narrowed anteriorly, with rather prominent dentiform anterior angles, the sides bisinuate ; 
the surface (a smooth space-down the middle excepted, this being finely canaliculate in the centre) closely 
covered with coarse, oblong, foveolate punctures, and broadly transversely depressed before the base. 
Elytra moderately elongate, subparallel, slightly widening from the base to the rounded posterior angle ; 
the lateral and apical margins finely serrulate; the apices separately rounded; each elytron with ten 
regular rows of deep, closely-packed punctures; the second, fourth, and eighth interspaces, together with 
the suture, costate, the second more strongly than the others. Legs short and stout. 
Length 24 lin. 
Hab. Mexico, Xucumanatlan in Guerrero (H. H. Smith). 
One specimen. Not very closely allied to any of the species described by Baly, but 
perhaps best placed near C. swhhumeralis. ‘The penultimate joints of the antenne are 
closely, but freely, articulated, and strongly transverse. | 
50 (a). Chalepus yucatanus, (Tab. XIII. fig. 25.) 
Moderately elongate, subparallel, subopaque ; black, the prothorax fulvous, with a rather broad black or 
fuscous median vitta, the elytra with a very broad fulvous lateral patch extending from the base to beyond 
the middle and obliquely truncate behind; the legs and antenne black. Head subopaque, almost smooth, 
the front moderately produced, feebly carinate anteriorly, the interocular space longitudinally trisulcate. 
Antenne very short, not one third the length of the body, thickening a little outwardly ; the joints cylin- 
drical, 3 much longer than 2 or 4, 4-10 transverse, 11 longer than 10, acuminate. Prothorax opaque, 
strongly transverse, a little flattened on the disc, transversely depressed behind, the sides feebly bisinuate 
and converging from the base, the anterior angles feebly dentiform ; the surface closely covered F$ith deep 
foveolate punctures. Llytra rather broad, moderately long, subparallel, slightly widening from the base
