The fossil is provisionally referred to the Exothecine Xenarcha, but it probably should form a distinct genus. It may perhaps belong to Heterospilus, which it also closely resembles. It may also be compared with Ecphylus. No disposal of it is satisfactory, but I do not like to propose a new generic name. Bathystomus (?) peritus, sp. n. (Fig. 17.) Anterior wing 3*1 mm. long; thorax with abdomen 22 mm. ; the thorax was apparently dark, the abdomen very pale luteous. Wings clear, stigma pale reddish, nervures colourless or almost. The wings are large and broad, the width of anterior wing a little over 1 mm. Abdomen sessile, not compressed. Fig-. Bathystomus (?) peritus, sp. n. Stigma large j second long, with a broad angle about middle above ; b. n. meeting „ which is in a line with its lower end ; disc. 1 broadly meeting second , I. 9671 (B.). The wing agrees exactly with Bathystomus, except that in the modern genus the b. n. goes a considerable distance basad of The abdomen also agrees well enough. The wing is much like that of Histeromervs, but in the latter the radial nervure is not angled at the second Accelius and some Meteorus {M. unicolor, Westm.) run to B. peritus in the above table, but are actually very Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London, Taylor and Francis, Ltd
