excision one-fourth distance to base, the posterior margin of which is produced 

 and angularly notched at middle forming two broad brown teeth. Male valve 

 distinctly triangular and pointed at apex, exceeding length of preceding segment. 

 Plates exceed valve by three times its length, somewhat concavely narrowed 

 from base to small blunt tips. 



Described from twenty-three specimens from Paradise Key, 

 22 collected by D. M. DeLong, Apr. 5-10, 1921, swept from 

 Panicum hemitomum (Maiden cane) in the everglades, and one 

 specimen collected by Schwarz and Barber, U. S. National 

 Museum Collection, Feb. 19, 1919; also one specimen collected 

 at Cleveland, Fla., Apr. 25, 1921, by J. N. Knull. 



Thammotettix virginianus, n. sp. 

 Plate 12, Fig. 2, 2a, 2b. 



Resembling fitchii in size and general appearance but with blunter head, 

 strongly marked with orange stripes and with distinct genital characters. Very 

 similar to Thamnotettix aureooitattus. 1 Length: female, 4 mm.; male, 3.5 mm. 



Vertex blunt, almost rounded, a little longer on middle than next eyes and a 

 little broader at base between eyes than length at middle. Pronotum twice as 

 wide as long, longer than vertex. E'.lytra long, greatly exceeding abdomen. 



Color: Dull yellowish marked with black and orange. Vertex with ocelli 

 and tour spots above margin black. Two approximate ones at apex and a 

 somewhat larger one either side just above ocellus. Vertex washed with orange, 

 a definite longitudinal stripe either side extending across pronotum and onto 

 scutellum. Pronotum with two fainter longitudinal stripes either side behind 

 eyes. Elytra orange shading to dusky orange at apex; veins pale, smoky mar- 

 gined on posterior portion. Beneath dull yellow, marked with orange. 



Genitalia: Female last ventral segment about one-half longer than preceding. 

 Posterior margin convexly rounding and slightly notched either side of a central, 

 rather narrow blunt embrowned tooth, produced at least one-third the length 

 of the segment. Male valve as long as last ventral segment, broadly convexly 

 rounded. Plates two and one-half times longer than valve, broad at base, 

 gradually narrowed to closely appressed tips which together are broadly 

 rounded. 



Described from two female specimens from Cape Charles, 

 Virginia, collected by the junior author, July 31, 1920, swept 

 from tall grasses along the sandy shore; and a male specimen 

 collected at Battle Point, Virginia, June 22, 1918, by the senior 

 author. 



Typhlocyba inscripta, n. sp. 

 Plate 12, Fig. 3, 3a, 3b, 3c. 



A milky white species with bizarre brown markings on apical portion of 

 wings. In general appearance resembling species of Empoa. Length 4 mm. 



Head rounded before, twice as wide between eyes as length at middle. Pro- 

 notum more than twice as long as vertex and much broader, with humeral
