250 HETEROMERA. 
surface closely and coarsely punctured, the punctuation becoming very much finer beyond the middle; legs 
entirely testaceous; fifth ventral segment shallowly transversely depressed in the middle and truncate at 
the apex in the male. 
Length 23-24 millim. (¢ 9.) 
Hab. Guatemata, Yzabal (Sallé), Rio Naranjo (Champion). 
Eleven examples, ten from the Pacific and one from the Atlantic slope. Extremely 
close to A. fulvipes, La Ferté, and only separable by the longer and stouter antenne 
and by the male having the fifth ventral segment transversely concave in the middle. 
It also approaches A. lutescens, but differs from that species in having the thorax more 
densely and more minutely punctured (and consequently more opaque), the elytra more 
truncate at the base and more uniformly punctured (the punctuation much coarser on 
the basal half), and the pubescence longer and coarser. 
Fam. MORDELLIDZE. 
Group ANASPIDES. 
The three known North-American genera are all represented within our region, and 
anew genus is required for some of the Central-American forms. The group is not 
nearly so numerous in species as the Mordellides in the warmer regions of the earth, 
and seventeen only are here recorded from Central America; of these ten belong to 
Pentaria, one to Diclidia, one to Anaspis, and five to a new genus. 
All the Central-American members of the group were obtained at a considerable 
elevation above the sea. 
DICLIDIA. 
Diclidia, Leconte, Proc. Acad. Phil. xiv. p. 48 (1862); J. B. Smith, Trans. Am. Ent. Soc. x. p. 75. 
The single species from Guatemala referred to this genus agrees accurately with 
Leconte’s definition. The compressed and much elevated mesosternum (this being very 
sharply carinate between the middle coxe in front) and the bilobed penultimate joint 
of the anterior and middle tarsi are its chief characters. The male of the Guatemalan 
insect, like that of the North-American one, possesses very peculiar appendages to the 
abdomen. ‘The sixth ventral segment is well exposed in the male, but it is covered by 
the fifth and not visible in the female. 
1. Diclidia undata. (Tab. XI. fige. 1, 9; la, terminal ventral segments of 
the abdomen, ¢ .) 
Moderately elongate, densely and very finely pubescent, finely transversely strigose above ; testaceous or flavo- 
_testaceous ; the prothorax irregularly mottled with piceous (between which ill-defined spots of the 
ground-colour are visible); the elytra with an irregular oblong patch on the middle of the disc at the 
base, a common strongly angulated rather broad median fascia, from which a branch extends upwards on 
either side of the suture, a broad anteapical fascia (extending forwards at the suture and sometimes on the
