Cotyleceps delicata Fowler 



(1905 Biologia Central!- Americana, Rhyncota, vol. I, p. 86, 



Metabrixia) 



Color a blackish-fuscous, paler beneath; frons clouded with brown, 

 the carinae paler. Dorsal surface black with a broad pale fulvous 

 vitta covering the entire vertex and the pro- and mesonotum on the 

 disc between the lateral carinae, and this vitta is continued along the 

 elytral commissure where it is paler in color, gradually narrowing 

 and becoming obscured. Elytra, macropterous, smoky with the veins 

 fuscous. Legs testaceous. 



Length to tip of elytra 6. mm. 



A series of six females and four males were taken by 

 the writer during 1921 at the following localities in Mis- 

 sissippi: Ocean Springs, July 24, 1920, and Aug. 3, 1921; 

 Pascagoula, Aug. 7, 1921; and Columbus, June 23, 1921. 

 Three specimens collected by F. M. Hull at Harlingen, 

 Texas, July 12, 1921, and a small series taken by the writer 

 in low woods near New Orleans, La., July 23, 1922, are at 

 hand- A pair in Prof. Osborn's collection taken by Wm. 

 Palmer at N. Alexandria, Va., July, 1907, and a female from 

 Orangeburg, So. Car., Aug. 18, 1914, F. H. Lathrop, have 

 also been studied. 



Van Duzee redescribed this species under the name of 

 Cixius dorsivittatus from a single female example from 

 Florida and Metcalf figures this same species (Fulgoridae 

 of Eastern No. Amer., Plate 44, fig. 77) and erected the 

 new genus Ciocixius to contain it. 



The Arrow Head, Sagitaria latifolia, is a definite food 

 plant of this species. This plant grows in low, moist places 

 in deep deciduous woods, and the writer took most of his 

 specimens sweeping pure stands of this plant at various 

 localities. Several specimens were also taken at bright 

 light traps. 



Cotyleceps aspersa Fowler 

 (1905 Biologia Centrali- Americana, p. 87, Metabrixia) 



This species is very close to the preceding one but is 

 distinguished by its slightly larger size, more mottled elytra, 

 and in having the commissural vitta decidedly less distinct. 

 Legs testaceous but somewhat variegated. Its length varies 

 from 6.5 to 7 mm.
