Readio: Ovipositors of Cicadellid^. 263 



very small, lobular tooth for a short distance on its dorsal edge; the longer, 

 wider \alvo bears thirteen primary teeth along the apical sixth of its dorsal 

 edge, medium in size, somewhat triangular in shape, with the caudal edge 

 longer than tlu^ cephalic, fairly regular in size, shape and spacing; bear small 

 secondary teeth along caudal edge, three to seven in number; tip of longer 

 valve notched with small teeth, continuous around the tip, thirteen on ventral 

 edge; area of ducts inconsiiicuous, ducts invisible except for circular openings; 

 open at ajiex. along dorsal edge of toothed area, and in basal shaft. 



Enipoasca mali (LeBaron). 



(PI. XXXIII, fig. 13.) 



Length. 0.8 mm.; greatest width, 0.03 mm. Very narrow and rodlike, apical 

 toothed portion only very little wider than basal shaft; greatly curved, 

 tip slightly narrowed, extreme apex narrowly rounded, chitinization light; 

 strengthening rod extends caudad as far as third dorsal tooth. The two 

 valves of the pair are not identical; the shorter, narrower valve bears only 

 very small, regular teeth along its dorsal edge for a short distance ; the longer, 

 wider valve bears eighteen primary teeth along the apical sixth of its dorsal 

 edge, these of medium size, regular as to size, shape and spacing, smaller 

 apically, and bear a few very fine and indistinct secondary teeth on the 

 caudal edge; the tip of the longer valve is notched with small teeth on both 

 edges, not continuous around the tip, about seven on the ventral edge; area 

 of ducts inconspicuous, ducts invisible except for circular openings; open 

 at apex and a few in the basal shaft. 



Genus Erythroneura Fitch. 



The ovipositors of two species of this genus have been examined 

 and found to be similar one to the other and also to the ovipositors 

 of the genus Enipoasca. In this genus the two valves of the pair 

 are not identical, but differ as to length, width, and size and number 

 of teeth. In one species the small, more numerous teeth are borne 

 by the longer, wider valve; in the other species the condition is 

 reversed. The teeth do not occur except on the apical fourth of the 

 valve. The area of ducts is inconspicuous, ducts when visible elon- 

 gate, duct openings visible. 



Erythroneura tricincta Fitch. 



(PI. XXXIII, fig. 8.) 



Length, L2 mm.; greatest width, 0.09 mm. Narrow and rodlike, the apical 

 toothed portion only slightly wider than the basal shaft, tapers caudad at 

 apex; distinctly curved, tip narrowed, extreme apex rounded, chitinization 

 very light ; strengthening rod extends caudad to a point about two-fifths the 

 length of the toothed portion of the longer valve. The two valves of the 

 pair are not identical ; the longer, wider valve bears a great many very small, 

 regular teeth along its dorsal edge for the apical fourth; the shorter, narrower 

 valve bears slightly larger, less numerous, regular teeth along its dorsal apical 

 edge; tip notched with teeth on both edges, not continuous aroimd the tip.
