Pompilus takes hold of her spider anywhere, but always drags it over the ground, walking backwards. Oxylelus clasps her fly with her hind legs ; Bembex with the second pair. Each works after her own fashion in a way that is relatively uniform for each species. The general style of the uest, its mode of construction, and its method of closure, are always performed, says Dr. Peck- ham, by each species in a similar manner, not indeed in circumstantial detail, but quite in the same way in a broad sense. Variation or modification is always present, but the tendency to depart from a nest of a given type is not ex- cessive. Some dig in the ground 2urved tunnels, with or.
