with median carina, each side pustulated. Scutellum tricarinate, with 

 numerous pustules outside of the lateral carinae. Elytra short, trun- 

 cate behind, the outer corners well-rounded, nervures slightly raised 

 but on account of their pale color rather indistinct. Dorsum of ab- 

 domen with a median ridge, a partially double row of pustules on 

 sides of each segment, which are weaker in the male. 



In the female the elytra and entire body is a dull sordid testaceous, 

 in the male a rosy or orange-yellow color. Legs pale testaceous. The 

 single macropterous female on hand is marked with fuscous in places 

 and the elytra are long, pale translucent, the nervures pale but distinct. 



The male plates or genital styles are rather long and thick, and 

 are narrowed to an incurved pointed apex. 



Length of male, 2.50 mm., of female 3.50-4 mm. 



Redescribed from a brachypterous series of two males 

 from Cat Island, seven miles off the Mississippi coast, Sept. 

 7, 1920, and six females and five males from Pascagoula, 

 Miss., Aug. 6, 1921, all taken by the writer sweeping marsh 

 grass, Spartina patens. At the latter place a number of 

 last instar nymphs were taken. The writer has also ex- 

 amined Prof. Osborn's series of ten brachypterous females 

 and three males also, and a macropterous female, collected 

 at Ames, la., and a female taken by H. S. Severin at Capa, 

 So. Dak,. Aug. 27, 1919. 



Metcalf has evidently redescribed the male of this species 

 under the name of Aphelonema rosa Metcalf, being misled 

 by the remarkable difference in coloration between the 

 sexes in this species. His name rosa must therefore fall 

 as a synonym of simplex UHLER as pointed out by Dr. Ball. 



Aphelonema simplex var. obscura Van Duzee 

 (1912 Bui. Buf. Soc. Nat. Sci., x, p. 499) 



Recorded from Ga., Fla., Kans. and Iowa. 



Originally described from Georgia material as a distinct 

 species but recently Ball has placed it as only a variety of 

 simplex. 



"Allied to simplex but smaller and darker in color. Vertex trans- 

 verse very short, but little broader than the bounding carinae. Frons 

 ovate oblong, distinctly narrower than in simplex; median carinae 

 feeble; clypeus but moderately incurved, feebly carinate. Pronotum 

 regularly rounded before without the slight angle observable in 

 simplex, evenly but obscurely pustulate, median carina obtuse; hind 

 margin but feebly arcuated; mesonotum with the smooth median area
