DUCIOLA.—ENDYTOCERA. 45 
8. Duciola punctata. 
Rufo-ferruginea, antennis, palpis pedibusque testaceis, pubescens ; elytris crebre evidenter punctatis. 
Long. 23 millim. 
Hab. Mexico, Acapulco (Hége). 
Antenne slender, with joints 8-10 subequal, each considerably longer than broad, 
the eighth twice as long as the seventh, the terminal joint conspicuously longer than 
the tenth, acuminate. Head elongate, deeply longitudinally bi-impressed ; eyes not 
prominent. Thorax nearly as long as broad, with two very minute tubercles in the 
middle on the front margin of the very deep transverse channel. Elytra rather longer 
than the thorax, somewhat closely and distinctly punctured, pubescent. Basal dorsal 
segment of the hind body much longer than the second. 
This insect also is unique, and I do not know the sex of the example; it has a large 
impression on the apical ventral plate. D. punctata is readily distinguished from 
D. scydmenilla by the punctate wing-cases, and from D. aberrans by the structure of 
the antenne. 
ENDYTOCERA. 
Antenne undecim-articulate, pubescentes, articulis inter se parum discretis; clava maxime elongata, ex 
articulis sex vel septem composita, Cox anteriores valde elongate, parallel. Corpus dense pubescens. 
This genus should be placed near Duciola, Reitter, from which it differs remarkably 
in the structure of its antenne. These organs are of a peculiar nature: the joints fit 
closely to one another, and are covered with a dense pubescence so that the articula- 
tions, especially those of the extremely elongate club, are difficult to count and distin- 
guish ; the first joint is rather large, and pubescent like the head, then follow three 
comparatively small joints, and then apparently six stouter elongate joints complete the 
organ ; the first of the outer six joints has, however, at its base a small joint which can 
only be detected by greatly bending the antenna, and thus there are really eleven 
joints. The palpi are small, the terminal joint slender, fusiform. The head is without 
depressions ; the points of insertion of the antenne are without tubercles, though 
placed on the front of a short prolongation so as to be extremely exposed; the under 
surface is densely pubescent, the pubescence divided by a glabrous suture furcate 
in front, the sides not at all distinct. The prosternum is rather large, densely 
pubescent; the front coxe are very long, parallel; the middle coxe rather prominent; 
the hind coxe contiguous; the metasternum rather long. The ventral rings are 
apparently only five in number, the basal ring being concealed by the coxa; on the 
dorsal surface five rings are visible, and the sides are strongly margined. The epipleure 
are marked off by a very sharp ridge. There are two quite small, very nearly equal, 
claws on the tarsi. 
These characters are taken from £E. vestita; the second species, E. cognata, appears 
to be really congeneric, though it exhibits a slight difference in the structure of the 
front of the head.
