The larviB went into the ground soon after their receipt, and we hope to obtain the fly from them in due time. Succu- lent galls perish so easily that they cannot well be pre- served, so we have made the accompanying drawing. (Fig. 42) of this Touch-me-not gall, u showing the entire gall, h a cross-section, with the cavities in which lie the larva;, and c the breast-bone of the larva highly magnified.
