Female puparium varying in colour; circular in outline, usually flat, sometimes rather convex; pellicles usually in the centre.

Male puparium rather longer than that of the female, the pellicle at one end; not carinated above.

Groups of spinnerets usually four, sometimes five, and in one American species (A. sabalis, Comstock) six; or, in a few cases, altogether wanting.

Adult females usually peg-top shaped.

([Plate IV.], Fig. 1.)

Female puparium circular, flat, brown; diameter, about 1/20in. The pellicles in the centre form sometimes a sort of boss or protuberance, of lighter colour than the rest.

Male puparium oval, flat, brownish, about 1/36in. in length.

Adult female light-yellow in colour, of the usual peg-top shape of the genus; length, about 1/30in.; corrugated—the last abdominal section, being very small, is much overlapped by the rest. Four groups of spinnerets, upper pair with fifteen orifices; lower pair, nine or ten. Abdomen terminating in several lobes, of which the four median are the largest; between the lobes scaly serrated hairs.
