Excerpt from The Entomologist's Monthly Magazine, Vol. 24[In this Magazine, vol. xvii, pp. 146, 147, December, 1880 (and also in other publications), I figured and noticed an extraordinary gall on Eucalyptus, forwarded by Baron von Mueller, and attributed to the Lepidoptera on the authority of larvæ in fluid said to have been extracted from similar galls. I also noticed what was supposed to be an undeveloped Lepidopterous chrysalis in a dried form found in the galls sent. A short time ago Mr. W. R. Jeffrey sent some sketches of similar galls made by his friend Mr. Hart, of Adelaide, and which the latter attributed to a species of Coccidœ, and I asked him to obtain further information. This has come in the form of a letter, from which the following extracts have been made, and an excellent figure by Mr. Hart, partially reproduced here for comparison with the figure on p. 146, vol. xvii. The error as to the position of the gall-maker was induced by Baron von Mueller's erroneous association of Lepidopterous larvæ with the galls, and it is somewhat singular that in these days of keen criticism no one has, until now, referred to the paper by Schrader ("read" June 2nd, 1862), in which, in all probability, the same insect and gall are noticed and figured, any slight differences in the form and size of the galls may be due to differences in the species of Eucalyptus, or to the age of the galls. Mr. Hart's figure is reproduced mainly because it possibly indicates the galls of the male in the smaller examples. But some of Schrader's galls were enormous, for he says he found one eleven inches long, and his figure indicates the horns as longer and less incurved at the tips than does mine of 1880, and in this respect Mr. Hart's figure is somewhat intermediate. These gall-making Coccids (Fam. Brachyscelidœ, Signoret) seem peculiar to Australia, and possibly also to Eucalyptus, and are no doubt numerous in species. I am indebted to Mr. Jeffrey for permission to use the drawing. - R. McLachlan.]"Since receiving your letter of November 24th I have done all that my unsatisfactory state of health would admit to clear up the mystery of the long-horned gall of the gum trees.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
