Some peculiarities in the early stages of some Butterflies
When rearing butterflies from eggs or larvae, one aims at obtaining perfect specimens or, if studying the life history, is satisfied with his observations on a batch of eggs reared under normal conditions. Only when broods are reared under abnormal and even drastic conditions such as scarcity of food, alternate foods or withering food, is the wonderful tenacity of some species revealed. This tenacity perhaps accounts for the appearance of certain species in a district where severe drought seemed to have exterminated everything. After drought migrants repopulate a district, but I refer to those species which do not migrate.

Notes on the distribution of some South African Butterflies
All collectors of butterflies welcomed the publication of Dr. G. van Son's first volume of ""The Butterflies of Southern Africa "". But the prolonged absence of an up-to-date complete work on our butterflies prompts me to add to earlier notes I have published in the JI. ent. Soc. Sthn. Africa, 1940, Vol. 3, p. 130 and 1946, Vol. 9, p.20 to assist collectors and observers.

A description of the Woodborer Oxypleurus nodieri Muls. (Coleoptera: Cerambycidae)
Because of the widespread occurrence of this woodborer in the Western Cape Province, it is felt that an accurate descriptionption of the insect is necessary, to aid entomologists and foresters in identifying it, especially as publications dealing with the taxonomic descriptionption of Oxypleurus nodieri Muls. are practically unobtainable in this country.

The genus lobocentrus Stal (Membracidae)
Since 1870 the lobocentrus Stal was descriptionbed and classifies differently by various researchers. The significant feature of the genus is the well developed, downwardly produced lobe of the posterior process, which almost or quite touches the apex of the scutellum. It seems desirable to review each species of the genus before descriptionbing the new species from South Africa. It differs in very important particulars from L. suffulta Dist., but more material is needed for further study.
