the surface coarsely, equally, and rather closely punctured; scutellum rather large, subtriangular, coarsely 
punctured ; elytra moderately long, rather strongly impressed on each side at the base within the broadly 
rounded humeri, subparallel in their basal half and thence rounded and narrowing to the apex, with rows 
of rather coarse and somewhat closely placed punctures which become coarser towards the sides and finer 
towards the apex, the interstices flat and each with a median row of punctures which upon the disc are 
almost as coarse as those of the striw; beneath sparsely pubescent, ceruleous with bronzy tints, the fifth 
ventral segment fusco-testaceous; the metasternum longitudinally impressed in the middle, very sparsely 
and finely punctured, and with coarse impressions at the sides, the ventral surface finely and more closely 
punctured, the fifth ventral segment with coarse scattered impressions in the middle; legs and antenne 
ceruleous, thickly clothed with bristly hairs. 
¢. Anterior tibie sinuous within. Fifth ventral segment flattened, almost transparent, very long and 
projecting, the sides subparallel and visible from above, the apical angles rounded, the apex broad and 
emarginate, the base deeply transversely impressed in the middle and articulated to the preceding 
segment by a broad membranous space; apical margin of the fourth segment sinuate-emarginate and a 
little thickened. The lateral lobes of the last ventral segment very broad, long, and curved, and some- 
what spoon-shaped, and broadly rounded and a little thickened at the apex. 
Length 63 millim.; breadth 23 millim. (¢.) 
Hab. Panama, Bugaba 1000 feet (Champion).

A large number of species have been referred to this genus, chiefly from the tropical 
regions of the Old and New Worlds. Eleven species only from Central America are 
here included in it, the numerous allied forms being referred to other genera. Alle- 
cula at present contains a very heterogeneous assemblage of species from all parts of 
the world ; and, when the numerous forms existing in collections are all described, will 
doubtless have to be extensively divided. The three North-American species referred to 
it belong to Lobopoda as here understood. In the Central-American species the anterior 
and intermediate tarsi have the third and fourth joints, and the posterior tarsi the 
penultimate joint, more or less lobed (very broadly in A. castaneipennis) beneath ; in the 
males of 4. ferox, A. gawmeri, and A. pilipes the first and second joints of the anterior 
tarsi are also lobed. In the male of A. feror the lateral lobes of the last ventral 
segment are greatly developed and each divided into two parts (one above the other), 
and in the female the fifth ventral segment exhibits a peculiar modification, the species 
thus differing in a remarkable way from the allied forms. 
In A. belti and A. pilipes the mandibles are truncate at the apex, and in A. ferox they 
are also broad and subtruncate, though feebly notched; but on this character alone it 
is not advisable to separate these species, connected as they are by intermediate forms. 
In all the species here included in the genus the antenne are very long and more or less 
filiform in both sexes ; in one or two, however, joints 4-10 are each a little dilated at 
their inner apical angle. A. depressa and the following three species differ from the
