Cernotina Oklahoma new species This species differs from calcea in the short cerci without mesal armature, fig. 60. Maxillary Palpus '. Fig. 59.— Ccrnolina calcea c? Genitalia Fig. 60.—Cernotina Oklahoma Male.—Size, color and general char- acteristics same as for the genotype. Diagnostic characters present only in the genitalia. Genitalia as in fig. 60. Tenth tergite incised as with calcea; the lateral lobes separated slightly more at their apex and more nearly triangular in shape. Cerci not projecting beyond lobes of tenth tergite; they are broad at the base and angle sharply mesad at the apex, the apical portion much more slender than the basal, and its distal corner produced into a short, narrow, fingerlike process. At the base of the each cercus is an angulate ventro-mesal lobe bearing at its apex a group of 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 Illinois.
