Original description

Content:  Anaulacomera cercalis, new species. (PI. II, fig. 22.)

This inconspicuous green species is allied to sulcata and securifera but the cerci of the male differ decidedly from those of either of these.

Description (male).—Head as described above under apicidentata. The legs are also much as in apicidentata, even as to the second dorsal spine of the intermediate tibiae being absent on one leg. The last dorsal segment of the abdomen is broadly rounded apically, above broadly and shallowly concave; supra-anal plate triangular, the apex rounded; cerci long and conspicuously branched; the basal portion is slightly flattened in the inner side, the apical portion conspicuously so, this apically compressed portion furnished beneath with two broad dull deflexed teeth and a more apical one very short and blunt and turned outward; the tip of the cercus itself is flattened, broad and pointed; at the basal fourth on the inner side is a broad vertically flattened appendage one-half as long as the main body of the cercus and directed at a right angle to the main body; this appendage expands somewhat apically and is dorso-apically deeply notched, forming a sort of open monkey-wrench appearance and bearing toward the base a tubercle; this remarkable cercus is hard to describe adequately and difficult to figure properly, though the general structure and appearances is shown with some accuracy at figure 22.

(female). Very like the male. The ovipositor is decidedly longer than the pronotum, gently curving upward apically, widest in the apical fourth, sides smooth, the margins very finely serrate in the apical half, more distinctly so apically.

Measurements.—Length: pronotum, male , 3.5 mm., female, 4 mm.; tegmina, male, 25 mm., female, 28 mm.; posterior femora, male, 14 mm., female, 17 mm.; cerci, male, 4 mm.; ovipositor, 9 mm. Width: pronotum posteriorly, male, female, about 2.25 mm.; tegmina mesially, male, 4.75 mm., female, 5 mm.; ovipositor mesially, 1.75 mm.

Described from five specimens: type male , October 19, 1906, Iconnicoff; allotype female, November 8, 1906, Iconnicoff; paratypes a and b, males, September, 1908, and January, 1909, Schunke; paratype c, female, November 11, 1906, Iconnicoff.

Type, allotype, and paratype a in the collection of the U. S. National Museum; paratypes b and c in the collection of Iconnicoff.

Cat. No. 21339, U. S. Nat. Mus.
