Excerpt from The Entomologist, 1919-1921: An Illustrated Journal of General Entomology; Volumes 52-54 There are certain groups of insects of apparently primitive type, represented by comparatively few living species, scattered widely over the earth. Such forms attract the attention of all students of insect evolution, and give rise to many speculations concerning their origin and history. Two such insects are represented in a small quantity of Burmese amber, just received from Mr. R. C. J. Swinhoe, of Mandalay. The specimens will be placed in the British Museum, to which they have been presented by Mr. Swinhoe. The amber occurs in Miocene clay, and is doubtless at least a million years old. It was, however, washed into the clay from other beds, and may be very much older than Miocene. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
