It feeds only on living snakes. The fine specimen exhibited is about ten feet in length. The Cobra-de-Capello, {Naja tripudians), of which some fine specimens are shown, is the terror of India, where it kills between 18,000 and 20,000 people annually! This is the m

The female beetle begins to lay her eggs either before orafter the entrance of the coccids. They are deposited singlyalong the edges of the frass ridges and evidently at intervals ofseveral hours or even days, for dissection of the beetles showsthat only a few eggs mature at a time in the ovaries.
