well diftinguiilied from other fpecies, by a black longitudinal wedge, furrounded by a
white border. The wedge is obtufe towards the anterior parts, and fliarp towards the anus.
A fafciculus of long hairs on the upper part, gives the refemblance of a V. where the abdomen
joins the thorax. The V. itfelf is compofed of black hairs, whitifli on the inner part.

and with black fides, marked next the legs with a greyiih line. The abdomen longiih,
ovate, hairy; for the moil part white above, marked with two white dots, near the thorax;

it made its efcape, from a hole in the box in which it was kept, and which I had forgot to
clofe after feeding it: hence it is not in my power to defcribe particulariy the arms and

of the fame fpecies in the fame place, very often, but in vain. Whether a windy feafon, or
a rainy one was the caufe of their abfence, or whether the ufual period of their coming there
had expired, I cannot tell. Plate 7, fig. 7.

mark, and then into a very deep black. It has alfo a white lucid margin next the legs; and
has alfo a quantity of long hair of a dark colour upon it. The abdomen ovate, blackiih,
