HABITAT: Antigua (_Drury_). "In Americæ meridionalis insulis" (_Fabr._).
Head small and hairy, being concealed beneath the thorax. The upper part
shines like silver. Mouth of a greyish colour, and furnished with four
palpi, whereof two are long and the other two short and thick. Eyes not
to be discerned. Antennæ about half the length of the insect; small, and
filiform, but full of joints. Thorax and abdomen dark lead-coloured,
shining like polished metal; being furnished along their sides with short
hairs. The former has a cream-coloured stripe crossing it from side to
side; it is also margined. In some specimens, the middle part of the
abdomen, from the thorax to the tail, is of a silvery white; but in
others the last ring only is so. At the extremity of the abdomen are
placed three tails, of equal lengths, like bristles, but very hairy.
These tails are in length about one-third of the whole insect; and, when
the creature is alive, are always carried in the position {77}represented
in the figure. The middle one seems immoveable, the others are not. All
the under part of the insect appears of a shining, silvery, white colour;
and near the extremity of the abdomen are placed four little horny
filaments, two on a side. Legs silvery. Thighs and tibiæ broad and thin.
