The colour was exactly that of the long dry grass in which it was moving--yellow. Length of body and neck, fourteen inches, and the size of a small straw; the legs were very long--five inches; the knee-joint half-way up; the arms had two joints--the regular elbow, and two-thirds of the distance another that doubled up, so that it could pick the food and carry it to its mouth. These again vary in size and colour from one inch in length to the size above described. The female is much larger than the male, which is a light-brown, the former of a sea-green colour. I think the mantis and the trap-door spider the most curious of the insect-world in South Africa. Many specimens of moths I collected in my waggon after dark, some of them very beautiful; the larger kinds I mostly found in the long grass on the plains. Butterflies were very plentiful in some parts, in others rarely any would be seen; each locality had its peculiar species. The wasps also amused me when standing in any particular locality for some time; the large black with purple wings was a constant visitor. When about making a nest to lay their eggs, they would fly into my waggon, examine every part minutely, and after fixing upon a particular corner, would fly away and return with a ball of mud the size of a pea, and commence to plaster the side of the waggon fixed upon. This would go on for two or three days, the two wasps, male and female, bringing in these little balls of mud, going and returning every minute until it was completed, leaving a little circular hole to each cavity in the clay nest, one-eighth of an inch in diameter when so completed. They would commence with one of the holes, there being five; the female would deposit the eggs, then the two would go out and return with a green caterpillar each, which they would push into the hole containing the eggs, then leave and return with balls of clay, and plaster up the hole so cleverly that it would be impossible to find it from the outside. The same labour was bestowed upon the other compartment of the nest, and when completed would be left for time to bring forth the young. Two other kinds of wasps were of quite a different shape, their slender bodies extended for half an inch, leaving a large egg-shaped ball at the end. These made exactly the same form of nest as the one described. A fourth kind, I noticed, would build their nest in the roofs of buildings; these would be suspended by a thin stem of a glutinous nature, upon which would be fixed from five to twenty cells similar to those of the bee. There have been eight and ten of all these kinds of nests in my waggon at one time, and during the intense heat of the weather, 106 degrees and sometimes 116 degrees in the shade, being too hot to move about, I have amused myself in watching the methodical way in which they so cleverly and beautifully completed their work, and in so short a time. The bees generally make their nests in
