The Strangest Insect In the World. To the Editor of the SCIENTIFIC AMERICAN : With reference to the article on the above subject in No. 1. Vol. lxxiii, of the SCIENTIFIC AMERICAN, will you permit me in the interests of scientific pursuit to remark that up to the present the moth which produces the caterpillar attacked by the fungus Sphaeria Robertsii is not known to scientists. though it is surmised to be a member of the genus Hepialus or swift moths of Europe? It was formerly thought to be Hepialus virescens, the giant green moth of New Zealand, called by the Maoris pppe, but that cannot be, as virescens is a wood borer and undergoes all its transformations chiefly in the lower parts of the trunk of the New Zealand currant or wine berry tree, Aristo-telia racemosa, and occasionally in other trees, such as manuka, leptospermum, the black maire, Oleaapetela, etc. The vegetable caterpillar, hotete (Maori), evidently pupates in the ground, and some must escape the attacks of the fungus spores to perpetuate the species, though the pupa has yet to be satisfactorily accounted for. From information obtained by my eldest son, G. H. Grapes. from the Maoris at Otaki, North Island. it appears tbat the grub or caterpillar pepeaweto (Maori) which begets this curiosity is dark olive green, about 3 inches long and found an inch or so beneath the surface of the soil, but, so far as I can ascertain, bas never been seen by an entomologist. Specimens in my possession prove that the head is not the sole point of attack, but that both extremities are attacked indifferently ; indeed, my experience tends to the belief that the anal extremity is the oftener selected by this singular and mysterious parasitical growth. The twig-like woody appendage is sometimes forked, and in one of my specimens exceeds 9 inches in length. The attacks of Robertsii seem altogether confined to the extremities of the caterpillar, unlike an allied British species, Isaria farinosa, which attacks the larvae of the cabbage moth, Mamestra brassicae. on the anal, dorsal, and abdominal regions indiscriminately. Parasitic fungi are met with in Australia and other countries which attack living and dead larvae, pupae, etc., consisting of upward of twenty-five recorded species, but none are so conspicuous or so remarkable, that I am aware of, as Sphaeria (formerly Torrubia) Robertsii, examples of which may be seen in many museums. Finally, I would observe that A weto is the Maori appellation for the larva of the New Zealand convolvulus hawk moth, Sphinx con-volvuli. frequently seen feeding on the kumara or sweet potato, Convolvulus chrysorrhizus. GEORGE J. GRAPHS. CaerbroiParaparaumu, North Island, New Zealand. How to Make a Million. A sprightly little sheet call Results, published in Chicago. devoted to advertising, gives an accountof a meeting of prominent business men in St. Louis. It was, in fact, a meeting- of commercial clubs of several cities, and among those present were a number of millionaires who were interviewed with the question, How can a man make a million dollars? and these are some of the brief replies : George M. Pullman: Could not tell you—really, I could not. I did not come down here to be interviewed, and, anyway, this is too short notice to give a comprehensive opinion. Marshall Field: Oh, pshaw! What do you ask such a question for ? There is no general recipe that I know of, unless it be industry, economy and a cheerful disposition. P. D. Armour : Oh, my gracious, what aquestion ! I have lost my patent for making money, and now dont know any more about it than anybody else. Go ask Marshall Field. He is making lots of money now. Lyman J. Gage : I did not come here to talk about money making. It occurs to me that men who want to make money will know how and where to proceed. Charles Fargo : What do you ask me for ? Ive got no money. Pullman could tell you, if he would. N K. Fairbank: I could not give you a rule, for there is no such thing in money making. Marvin Hughitt: Work like the devil. and hold on to what you make. A man must solve his own problem—nobody can do that for him. Franklin MacVeagh : Well, that is a poser. I will indorse all that Mr. Hughitt has said, however. E. M. Phelps: Go talk with those men who know—I dont. Which all goes to show, adds Results. that the reporter went to the wrong people. He should have interviewed the financial experts. It is clear that this reporter never did any interviewing for an advertising journal. What does a millionaire know about, making money, or a successful advertiser know about advertising? The men who have really done anything never want to tell how they did it.
