By the kind intervention of Sir William Dawson, the Rev. H. H. Higgins has sent me two new Carboniferous Insects of sufficient interest to bring to the attention of English palæontologists. They are both preserved in the Liverpool Museum, one having been presented to it by Major Chambers as long ago as January, 1858; while the other was mentioned by Mr. Higgins in his presidential address to the Liverpool Naturalists' Field Club in 1871, figured on the plate of the Ravenhead fossils in the Liverpool Museum (fig. 15) which accompanies it. Both the wings are gigantic.
