The closing years of the royal line of the Middle Kingdom, commonly called the Twelfth and Thirteenth Dynasties, are marked by a special variety of beetle, which has a high back (particularly at the _prothorax_, where the scarab is thickest) and a narrow waist, produced by an indent on either side at the point where the _prothorax_ and _elytra_ adjoin. The head shows _clypeus_ and eyes: the legs are usually shown in outline only, while the _elytra_ are not marked. There is a second type, characteristic also of these times, which is in reality a development from earlier forms, as may be seen by comparing the example in fig. 64 with that previously illustrated in fig. 60. The tendency to decorative effect seen in this case is further exemplified by a number of scarabs which seem to follow the prototype of fig. 61, though failing to preserve the quality of the lines and cutting. [Illustration: Figs. 64 and 65.] [Sidenote: The Hyksos Period.] As previously mentioned, the type of back in which no _elytra_ are shown remains the common variety through the Hyksos period. A short notch on each side indicates the point of division of the _prothorax_ from the body, and in the example shown in fig. 65 the legs are suggested only. The head and _clypeus_ are plain; the eye is sometimes represented. A decorative effect is produced in some instances, as in fig. 66, by representing hairy legs upon the back of the beetle. A unique example for the period is illustrated in fig. 67, where the back is scored with lines diagonally in each direction. Another typical form is shown in fig. 68, in which the threading holes are supported by a ring carved with the scarab, while the beetle itself is developed apparently from the type in fig. 63. In such scarabs the hairy legs upon the back occasionally may be noted. Another Hyksos type characteristically represents the human head (fig. 69, and compare the scarab of King Apepŷ figured in Plate I) upon the body of the scarab with or without the legs over the back.
