A recently found fossil from the old Scudder pit (?) appears to be a large female horntail. It shows the ventral aspect. Compared with modern Siricidae, the length of its ovipositor in relation to the body proper suggests modern Xeris spectrum. Unfortunately the venation is incompletely preserved on both wings. In addition to this the forewings and hindwings overlap to some extent on each side. What venation is decipherable is seen in the two sketches. It does not seem to agree with any of the modern genera examined but approaches that of Sirex more closely than any other. Both antennae are faintly indicated. They are stout, many-segmented and in keeping with those of Siricidae. Both hind legs are preserved faintly almost throughout their length. They are stout, and the individual segments are clearly defined.
