apical teeth veiy small and broadly rounded, distal teeth larger and more 

 sharply pointed; bear no secondary teeth; tip bears no teeth; area of ducts 

 conspicuous, ducts elongate, rather straight, circular openings visible; open 

 along ventral apical edge (twenty-two), at extreme apex (one), along dorsal 

 edge of toothed area, very noticeably in teeth three and four, in each of which 

 three to four ducts open, and in the basal rod; the two valves of the pair are 

 joined one to the other by a distinct, elongate, narrow, heavily chitinized con- 

 nection present on the dorsal edge of the basal rod. 



Tinobregnius vittatus Van Duzee. 



(PI. XXXIII, fig. 1.) 



Length, 2.7 mm.; greatest width, 0.19 mm. Long, narrow and rodlike, apical 

 toothed portion only shghtly wider than basal rod. tapers caudad at apex; no 

 preapical prominence; distinctly curved, tip evenly naiTOwed, extreme apex 

 rounded, chitinization moderately heavy, heavier than in Jasms olitorius; 

 strengthening rod extends caudad as far as eighth dorsal tooth. Toothed area 

 on dorsal edge occupies apical third; teeth ten to eleven in number, apical 

 teeth small and broadly rounded, distal teeth larger and more sharply pointed; 

 bear no secondary teeth; tip bears no teeth; area of ducts conspicuous, ducts 

 elongate, rather straight, duct openings visible; open along ventral apical 

 edges (twelve), at extreme apex (one), along dorsal edge of toothed area, and 

 in the entire length of basal rod; the two valves of the pair are joined one to 

 the other by a distinct, elongate, narrow, heavily chitinized connection present 

 on the dorsal edge of the basal rod, occupying about one-fifth of the length of 

 the basal shaft. 



This ovipositor is very similar to that of Jassus olitorius. 



Cicadula punctifrons var. repleta Fieber. 



(PI. XXIV, fig. 9; pi. XXXIII, fig. 3.) 



Length, 2.2 mm.; greatest width, 0.17 mm. About the same width for entire 

 length, narrows ■ caudad at apex; no preapical prominence; slightly curved, tip 

 narrowed by curving ventral edge, bears a finely toothed prominence on the 

 dorsal edge, extreme apex narrowly rounded, chitinization very light; strength- 

 ening rod extends caudad as far as fourth dorsal tooth from apex. Toothed 

 area on doi"sal edge occupies the apical two-fifths; teeth fifteen in number, 

 rather large, rounded, regular as to size, shape and spacing; bear a few fine 

 secondary teeth on both edges, continuous around the apices of the primary 

 teeth, those on caudal edge larger and more distinct than those on ventral 

 edge, two to eight present on the ventral edge; there are fine, radiating hues 

 extending from the interior of each tooth to the margin; the tip is notched 

 with small teeth on both edges, not continuous around the tip, twenty-five on 

 ventral edge; area of ducts inconspicuous, ducts invisible except for circular 

 openings, which are easily visible; open along ventral apical edge (five), at 

 extreme apex (one), along dorsal edge of toothed area, and in the basal area; 

 the two valves of the pair are joined one to the other by a poorly defined, 

 elongate, hghtly chitinized connection present on the dorsal edge of the basal 

 area, occupies about one-fourth the entire length.
