I have seen little pictures made with the scales of butterflies' wings, with blue skies and green trees and everything. So you see a butterfly paint-box is not altogether a make-believe, though it is not an easy paint-box for young people to paint with. TWO WONDERFUL WASPS (JUNE) I expect you all must know the Common Yellow Wasps--the kind that come buzzing into the jam at tea-time; and I want to tell you this about them--that I don't think they ever really get angry if there is jam about and you leave them alone, though, when small people jump up and scream, and edge away from the table, and make bad shots at them with spoons, they get so frightened and bewildered, poor things, that they may sting somebody, because they feel they really must do something exciting. [Illustration: This is one of Spinipes' burrows opened up. There is an egg at the bottom on the left-hand side and a caterpillar on the right-hand side. The egg is hanging by a silk thread, but you can't see this] Perhaps some of you do _not_ know that there are seven different kinds of these Yellow Wasps to be met with in this country of ours, and I should be surprised to hear that any of you know _much_ about the two Black Wasps whose story I am going to tell you. I say "black," because they _look_ black, though both of them have yellow girdles on their bodies. I wish they had English names; for I am sure they both deserve them; and English names are much easier to remember than Latin ones. However, Latin names are the only ones I know for them, so we must make the best of it, and call one of them Spinipes (you must read this as if it were Spiny Peas) and the other Crabro. We will take Spinipes first. If you look at the picture on the opposite page, you will see what she is like, and, if you look at the picture in Spinipes the Sand-Wasp (p. 151) you will see one of the clever things she does. [Illustration: This is a little picture of Spinipes bringing up a grub, which she is clasping beneath her body] She is building a little tube out of sand which is so delicate that the slightest touch from one of our own clumsy fingers will knock it down like a card-house, but it is strong enough for her to crawl inside; and she has to crawl inside very often, as you will see. I expect you will all want to know how she builds it, and what it is for. I will tell you how she builds it to begin with. You must know first that she has a pair of jaws which work quite differently from ours. Instead of moving up and down, they move across each other from side to side just like a pair of scissors.
