Ventral margin of the male pygofer with a short median tooth; 

 genital styles deflexed downwards at apex, and curved backwards 

 somewhat hook-shaped. 



Length of body 3.50 mm.; length to tip of elytra 4.50 5.75 mm. 



Redescribed from three females taken by the writer at 

 Okolona, Miss., June 28, 1921, and Tupelo, Miss., July 1, 

 1921, and several specimens in Prof. Herbert Osborn's col- 

 lection from Iowa and New York. 



Oliarus franciscanus STAL 

 (1859 Freg. Eugen. Resa., Ins., p. 273, Cixius). 



Widely distributed over most of the entire United States 

 and is also known from the West Indies. 



Form and general appearance of aridus, but much 

 smaller. Smaller and narrower than humilis and without 

 the infuscated apical portion of the elytra. The small size 

 and unmarked nervures readily distinguish this species. 



Vertex very long and narrow comparatively, definitely produced 

 in front of the eyes and angulate with the frons, nearly a half longer 

 than broad; black with the carinae pale. Frons enlarged to apex, 

 brown with the lateral edges and median carina pale. Pronotum 

 short, fuscous with the lateral carinae and margins paler. Scutellum 

 5-carinate, dark fuscous, paler on the disc. Elytra long and narrow, 

 subhyaline, the nervures yellow and only very obscurely and minutely 

 marked with black dots before the stigma; in apical portion these 

 nervures are more or less smoky and punctured with black. Beneath 

 testaceous to fulvous-brown. Legs testaceous-brown. 



Redescribed from two females and a male taken by the 

 writer by sweeping Juncus and sedges at edge of a bayou 

 at Ocean Springs, Miss., June 26, 1921, and numerous fe- 

 males in the Osborn collection from N. J., D. C., N. H., and 

 Ohio. 



Oliarus quinquelineatus SAY 



(1830 Jr. Acad. Nat. Sci. Phila., vi, p. 241; Compl. Writ, 

 ii, p. 375, Plata). 



This is our most abundant and widely distributed North 

 American species of the genus. Recorded from Quebec, 

 Ont, N. Y., N. J., Ohio, N. C., Fla. and Colorado. 



Closely related to vicarius but proportionately broader 

 and shorter, with heavier elytral maculations, a blacker 

 and nearly quadrate stigma and a distinctly broader frons. 



Vertex rather broad, fuscous with a white spot on each side next 

 to the eye. Frons greatly broadened to apex, with a prominent
