INSECT RIVALS OF THE RAINBOW sitism. Man is the great para site, the unbridled thief of all that is fit to eat. He steals the milk from the lamb, he steals the honey from the children of the bee, even as the Melecta bee pilfers the pottage of the An thophora bee's sons." The species reproduced are: Crocisa crucifera Ckll. (Plate XII, figure 3), occurring in the Philippine Islands; Triepeolus quadrifasciatusSay. (Plate XII, figure II), inhabiting North America. Anthophora Bee Family (Anthophoridac). This family of bees is widely distributed throughout the world. In North America nearly 1oo species have been described, but the habits of only a few of these have been studied. The nests of fa miliar species usually are built in steeply inclined or perpen dicular banks of earth, prefer ably in those of compact clay. Nearly all of the species are gregarious, hundreds of indi viduals building their nests close together in the same bank of earth. In the construction of their homes the Anthophoras build a cylindrical tube of clay, extending outward and down ward from the entrance of the tunnel. The outside of this tube is rough, but the inside smooth. It is composed of small pellets of earth compacted together, which have been brought out of the tunnel when wet and molded into the desired form. In ex cavating the tunnel the bees find the clay hard, so they visit a watering place and convert themselves into insectean tanks to carry sufficient supply to the burrow to soften the clay and make it workable like putty. The Anthophora bees have many foes, before whose attacks they are practically helpless. The species reproduced is An thophora sonata Linn. (Plate XII, figure 5), found in south ern Asia, Malay Peninsula, and Philippine Islands. TRUE FLIES (Order Diptera) Plate XIV This large order of insects embraces all the two-winged flies, which include the horse A CHINESE CRICKET ARENA In the bowl is the cricket house with the lid on, at the upper left a food rack with a bean lying beside it, and at the upper right a water trough (see, also, page 63). Photographs by James Dorsett CRICKET GLADIATORS The fighting ring is made of a portion of a large bamboo culm. Betting in China on the results is as lively as that at a horse race or at a game of jai alai in Cuba.
