to the rounded posterior angle ; the apices almost conjointly rounded; the lateral margin finely serrulate, 
the apical margin denticulate ; each elytron with ten rows of punctures; the second, fourth, and eighth 
interspaces throughout, and the sixth at the base, costate, the second and fourth more broadly and 
strongly than the others. Legs rather short. 
Length 3 lin. 
Hab. Mexico, Temax in North Yucatan (Gaumer). 
Two specimens. ‘This species is nearest allied to C. hepburni, Baly, but it has much 
more strongly costate elytra, the sixth interspace also being costate towards the base ; 
and the prothorax is more opaque and has obtuse anterior angles. The coloration 
resembles that of C. contubernalis and C. chapuisi, Baly; but both these species are 
more elongate, and have a short additional row of punctures at the base of the elytra, 
and longer antenne. The penultimate joints of the antenne are closely, but freely, 
articulated and transverse. | 
Chalepus acuticornis (p. 79). 
To the Mexican localities given, add:—Dos Arroyos, Rincon, and Acapulco in 
Guerrero, Atoyac in Vera Cruz (H. H. Smith), Temax in North Yucatan (Gauwmer). 
Sent in abundance from Teapa. 
Chalepus chapuisi (p. 81). 
To the Mexican locality given, add:—Atoyac in Vera Cruz, Teapa in Tabasco 
(H. H. Smith), Temax in North Yucatan (Gaumer). 
Chalepus waterhousii (pp. 81, 121). 
This insect has been found in abundance by Mr. Smith at Teapa, the specimens 
showing no variation in colour. In the males the anterior and posterior tibiz are 
each armed with a sharp triangular tooth on the inner side near the apex. The legs 
are long and slender in both sexes. | 
Chalepus mediolineatus (p. 122). 
To the Mexican localities given, add:—Amula and Chilpancingo in Guerrero 
(H. H. Smith). 
Eight specimens. This insect is closely allied to, and perhaps not really distinct 
from, C. contubernalis, Baly. 
Chalepus omogerus (p. 83). 
To the Mexican localities given, add:—Xucumanatlan, Chilpancingo, Amula, and 
Tepetlapa in Guerrero, Cuernavaca in Morelos, Atoyac in Vera Cruz, Teapa in Tabasco
