Posterior abdominal segments somewhat attenuated. Subanal plate apical, large, pale, spinosely imbricated, with 80-90 hairs varying in size from small and fine to long and stout (cf. that of vivipara with only 10-12 hairs): subgenital plate large but not obviously demarcated; presence indicated by 2 transverse groups of variously sized, fine, pale hairs; each group with 30-40 hairs (cf. that of aptera vivipara, with 2 rows each of usually 6 hairs). Gonapophyses borne on 3 pronounced tubercles, the outer tubercles, 42-64 /mi long, both inclined postero- lateral^ and each with 4-6 hairs; inner tubercle shorter, 35-50 /mi long, some- times appearing faintly bifid at apex; with 6-8 hairs (cf. viviparae whose gono- pophyses consist of 4 groups each of 2-5 hairs, which are very rarely borne on 3 very small, flat, pale tubercles). For further comparison with other morphs, see Table 2. An internal structure, which persists after maceration, is very conspicuous in the abdomen of some oviparae. This structure consists of two large, broad, irregularly shaped, greenish arms which are united posteriorly by a narrow isthmus. It is also present in oviparoid nymphs, but the arms are not united. Dissection and serial sections showed that the structure corresponded to the accessory glands of the reproductive system. The sections also showed that the accessory glands contain a refractile green substance which is not removed by ordinary histological solvents. The precise nature and function of this
