REVISION OF TRIBE ERllHOMEXELLINI OMAN 165 



Ovipositor sheath extending beyond tip of py gofer ; female py gofer 

 with numerous setae. Male valve hidden or very small ; male plates 

 more or less elongate; styles relatively small and curved downward 

 distally ; sternal apodemes absent. 



Type of genus, Pagaronia 13-punctata Ball, 1902. 



Three species in addition to the genotype are recognized as belong- 

 ing to the genus. Tettigonia tHpunctata Fitch, 1851 (New York 

 State Cab., p. 55), which has been referred to Pagwronia, belongs in 

 the subfamily Cicadellinae on the basis of the position of the ocelli 

 and the venation of the hind wings, and for it the genus Plesiommata 

 Provancher,^ 1889 (p. 263), is available. 



KEY TO THE SPECIES OF PAGARONIA 



1. Black markings on head and thorax consisting of numerous ir- 



regular blotches (pi. 5, fig. 1) triunata Ball 



Black markings on head and thorax consisting of small, definite 



spots (pi. 5, fig. 2), or absent 2 



2. Posterior margin of seventh sternite of female not notched 



medially. Terminal processes of aedeagus extending beyond 



shaft of aedeagus (pi. 5, fig. 2B) furcata, new species 



Posterior margin of seventh sternite of female with a faint 

 notch medially. Terminal processes of aedeagus extending 

 laterad, and to some extend back along shaft of aedeagus 

 (pi. 5, figs. 3A, 4A) 3 



3. Aedeagus and its terminal processes slender, the latter not serrate 



(pi. 5, fig. 3A) confusa, new species 



Aedeagus and its terminal processes stout, the latter serrate on 



outer margins (pi. 5, fig. 4A) 13-punctata Ball 



PAGARONIA TRIUNATA Ball 



Plate 5, Figubes 1, lA 

 Pagaronia IS-punctata var. trimiaia Ball, Can. Ent., vol. 34, p. 20, 1902. 



Easily distinguished from other species of the genus by the irregu- 

 lar black markings on the head and the long, slender male plates. 

 Length 7.7-9.25 mm. 



General ground color sordid yellowish white. Clypeus with 11 

 or 12 pairs of short, transverse, brown or fuscous lines laterally, and 

 a small black spot just below the apex of the head medially. An- 

 terior margin of head with a small black spot next each eye and a 

 large, irregular black mark in front of each ocellus, each of these 

 frequently divided to form two irregular blotches. Crown with 

 black to fuscous marks as follows : A small spot medially anterior to 

 ocelli, another next each eye, a pair of elongate spots on posterior 



1 S. E. Crumb has called my attention to the fact that certain copies of Provancher's 

 "Petite Paune Entomologique du Canada," vol. ?•, 1S89, contain the description of Plesiom- 

 mata, which is based on a single species, tiundulata, described as new in the same publi- 

 cation. It is apparent that Plesiommata Mundulata Provanchei', 1889, Is synonymous with 

 Tettigonia tripunctata Fitch, 1851 (new synonymy).
