Re.\dio: Ovipositors of Cicadellid.e. 257 



medium size, of a general triangular shape, with the caudal edge longer than 

 the cephalic and the apex rounded broadly, fairly regular as to size, shape, 

 and spacing, though not entirely so; bear small secondary teeth on caudal 

 edge and a few also bear a single secondary tooth on the cephalic edge; tip 

 notched with small teeth on both edges, not continuous around the tip, those 

 on ventral edge larger and more distinct, about fourteen present on ventral 

 edge ; area of ducts conspicuous, granular in appearance, circular duct openings 

 visible; present along ventral apical edge (twelve), at extreme apex (one), along 

 dorsal edge of toothed area, and in basal region where elongate ducts are visible; 

 the two valves of the pair are joined one to the other by a distinct, heavily 

 chitinized, rather short, rectangular connection present on the dorsal edge of 

 the basal area. 



Thamnotettix longidus Gillette and Baker. 



(PI. XXXII, fig. 4.) 



Length, 1.3 mm.; greatest width, 0.17 mm. Apical portion distinctlj^ wider 

 than basal portion, tapers caudad at apex; no preapical prominence; slightly 

 curved, tip narrowed, extreme apex narrowly rounded, chitinization medium; 

 strengthening rod extends caudad as far as sixth dorsal tooth from apex. 

 Toothed area on dorsal edge occupies somewhat more than apical half; thirty- 

 one primarj' teeth present, in the general shape of an obtuse triangle, of 

 medium size, fairlj' regular as to size and shape but not entirely so, uneven in 

 spacing; bear small secondary teeth on both edges, four to twelve on caudal 

 edge and one to four on cephalic edge, secondary teeth continuous around the 

 apex of each tooth; tip notched with small teeth on both dorsal and ventral 

 edge, not continuous around the apex, eight on ventral edge; area of ducts 

 conspicuous, granular in appearance, duct openings visible; open along ven- 

 tral apical edge (eight), at extreme apex (one), along dorsal edge of toothed 

 area (about one to each tooth), and in the basal area; the two valves of the 

 pair are joined one to the other by a distinct, elongate, heavily chitinized 

 connection present on the dorsal edge of the basal area, occupies less than a 

 fifth of the entire length. 



Genus Chlorotettix Van Duzee. 



The ovipositors of two species of this genus have been examined 

 and found to be generally similar. The basal third may or may not 

 be narrower than the apical two-thirds, which tapers to the apex 

 and bears teeth along its dorsal edge. The primary teeth differ in 

 number, shape, and number of secondary teeth in the two species. 

 The tip is notched on both edges with small teeth, not continuous 

 around the tip. The area of ducts is granular in appearance and 

 the duct openings are visible. The two valves of the pair are joined 

 one to the other by a chitinous connection present on the dorsal edge 

 of the basal area.
