Possibly they are for the respiration of the larva before it transforms to pupa and it re- mains in the cocoon unchanged through the winter, transforming to pupa only the following spring and shortly before the appearance of the true insc :t. When the adult hatches it gnaws its way out of the cocoon and so on up through the burrow to the surface of the ground, thus accomplishing its life-round in a full year. This big digger wasp is very abundant in mid-summer throughout the southern states. It stings severely, and, it is per- haps needless to say, should be avoided. The Socia! Wasps and their Allies. (Super-family VespoiJea.) All of the social wasps belong to this super-family, and there are also brought into it a number of solit;iry wasps, as well as the so-called cuckoo of the old family Chrysididi-, and some strange insects that were formerly plived in the parasitic family Proc- totrypida.'. but which are now made a family by themselves under the name Bethylidu;. There are other parasitic groi ps in this super- family, and it also contains the curious creatures known as cow-kil- lers, cow-ants, solitary ints. or velvet ants of the family .Mutillidie, which have habits, but closely re- semble the true ants. All these forms, differing however widely m habit, teed tor the most part in their early stages upon other insects or upon the remains of other insects.
