Stenocranus vittatus Stal. 

 (1862 Berliner Ent. Zeits., VI, p. 315). 



This species, described from Carolina and Pennsylvania by 

 Stal as Delphax vittatus, has not since been recognized. I have 

 on hand a single female, collected at Gainesville, Fla., by the 

 writer in 1917, a series of four females and two males collected 

 by C. J. Drake at the same locality. May 5, 1918, one male 

 from Hattiesburg, Miss., Aug. 10, 1921, and a series of two 

 males and a female taken by the writer sweeping grass and 

 sedges in a swamp near Meridian, Miss., Aug. 14, 1921, that 

 I place as this species. 



Although very strongly resembling dorsalis and probably long 

 confused with that species, it is quite distinct and is easily distinguished 

 by its smaller size and the shape of the male genital styles. 



Identical in structure and wing venation with dorsalis. General 

 color darker brown with the median white dorsal vitta very distinct 

 itself and made very prominent by the deeper fuscous of the pronotum, 

 scutellum and elytra. Intra-carinal spaces of front and clypeus dark 

 fuscous. Antenna pale. Elytra of a much darker fuscous on corium 

 than in dorsalis and there is a dark brown macula towards apex, with 

 the apical nervures prominently infuscated. Tergum of female marked 

 with fuscous and red, darker in male. Femora and tibiae lineated with 

 fuscous. 



Female pygofer pale fuscous, broad, foliaceous, greatly resembling 

 that of dorsalis, but broadest apically and not so closely appressed to 

 the genital segment. 



Male pygofer fuscous, comparatively smaller than in dorsalis; 

 genital styles broad at base, abruptly narrowed almost midway, thence 

 deeply emarginate, and then roundingly drawn out to acute tip; anal 

 tube with two acute lateral processes on ventral margin. 



Length of body, 2.25 mm. ; length to tip of elytra, 3.50-4.25 mm. 



I include here the original description in Latin and a transla- 

 tion of the same : 



''Delphax vittata Stal. — griseo-straminea, supra infuscata; fronte 

 clypeoque fuscis, pallido-carinatis ; vitta verticis thoracis scutellique 

 nee non commissura pure stramineis ; tegminibus fuscescentibus apicem 

 versus obscurioribus, maculis duabus parvis marginis commissuralis 

 prope apicem, parteque lata costali subvinaceo-hyalinis, venis trans- 

 versis apicalibus hujus partis fuscis et fusco-marginatis ; capite modice 

 prominente. 9 . Long, cum tegm. 5 millim. 



"Patria: Carolina meridionalis et Pennsylvania. (Mus. Holm.)." 



Delphax vittata Stal. — gray-stramineous, infuscated above; frons 

 and clypeus fuscous, palely carinated; the vitta on vertex, thorax, and 

 scutellum bright stramineous and also the commisure, stramineous. 

 Tegmina fuscous, rather obscure towards the apex, with two small
