PUNE-411 005 (M.S.India). observations of well over six years, in certain localities in Maharashtra State (M.S.) a southwestern region of India. It forms a part of 'Survey, Taxonomy and Etho-ecological studies on Tetrigids,' an ongoing research project (F.I-20/79-PP) supported by Indian Council of Agricultural Research, New Delhi. Potua sabulosa belongs to sub-family Cladonotinae. The species was first taxonomically described by Hancock (1915) and the habitat was recorded as Venna valley, Mahabaleshwar (M'shwar), Dist. Satara. In our extensive survey, we collected P. sabulosa not only from Venna valley but also from other valleys in M'shwar, namely Blue valley, Krishna valley and Koyana valley. In the region under survey, we also collected these insects from certain other localities of Western Ghats of Maharashtra, such as, Pratapgad, Panchgani in Dist. Satara and Sinhagad, in Dist. Pune. Our collection of P. sabulosa from these new localities constitutes a first record. MATERIALS AND METHODS Samples of living Potua were collected from the above mentioned localities. The insects are somewhat difficult to locate on account of

The correlation between nutrition and reproduction with reference to two grouse locusts, EU$celimena harpaqo (Tetrigidae: Scelirneninae) and Potua sabulosa (Tetrigidae: Cladonotinae) is assessed. As far as Euscelimena harpaqo is concerned the impact of nutrition on reproduction is presented with reference to ovarian development in certain nymphal stages and in the adult. On the other hand, the impact is evaluated from an altogether different angle as far as Potua sabulosa is concerned. This pigmy locust prefers moss as food and tides over winter and hazardous summer as adult. During this period it almost does not feed. This peculiar feature is used as a parameter to assess the nature of impact in P. sabulosa.

Laboratory observations on the post-embryonie development of the grouselocust, Euscelimena harpago Serville (Tetrigidae) is are presented. The eggs are depositOO a loose cluster in moist soil. All hoppers of a given cluster emerge almost at the same time. The fecundity rate is high. Morphometric studies indicate that there is a progressive increase in tho size among different body parts except the Pronotum which increases greatly Immediately alU!r moulting of the last instar into the adult. There are 6 nymphal instars in the male and 7 in the female. It took about 55 days to complete the post-embryonic development in the male and about 70 days in the female. The last instar in the female shows tremendous increase in weJght .nd I prolonged, dormant nymphal period during summer. Field obsel'\l'ations on the various instan indicate that they reed on humus, algae and moss and show structural and behavioural adaptations for semi-aquatic life.
