From the posterior margin of the postocciput, two pairs of apodemes project into the thorax, providing points of attachment for muscles. The longer of these, the occipital condyles (0), extends dorsally from the ventrolateral regions of the postocciput. Dorsal to them are the much shorter lateral apo

Lateral view of G. ooulatus female. Tergum. The prothoracic tergum is a large plate covering- much of the anterior half of the body dorsally (Fig. 1). Much of its area is due to marginal evaginations, and the actual pro- thoracic cavity is comparatively small. These evaginations pro- duce lobes which overlap the postocciput anteriorly and the mesonotum posteriorly. They are especially pronounced along the posterior and posterolateral tergal margins, where they form a broad posterior protergal lohe (LP) (the "tergal flap" of IMalouf, 1933, and the " Hinterlappen" of Larsen, 1945a and b) shielding the anterior part of the mesonotum. The antero- lateral lobes of the protergum are concave anteriorly, conforming to the shape of the head at the bases of the compound eyes. The two walls of all these marginal evaginations are fused together and appear as a single layer. A pronounced transverse ridge.
