central disc by distinct curved carinae which unite at the vertex. The 

 frons, genae, antennae, and clypeus yellowish-brown without mark- 

 ings. Pronotum about as long as the vertex, obtusely-angled in front, 

 with two impressed spots on the disc. Scutellum as long as the pro- 

 notum, indistinctly carinate, with two dark spots between the carinae. 

 Elytra twice as long as broad, rounded behind, the longitudinal veins 

 distinct, curved outwards posteriorly, with the outer ulnar vein forked 

 near its base, the numerous cross-veins mostly simple; the surface of 

 the elytra is spotted with pitch brown to black making the veins that 

 are light-colored stand out more prominent. Wings smoky brown. 

 Beneath brownish-yellow, at times greenish, abdominal segments 

 marked with fuscous on the disc and small black dots on the sides, 

 the apex fuscous. Legs very thickly and finely dotted, with a small 

 black point on the tip of the femora; the ridges of the tibiae, the 

 tips of the spines, and the claws, dark fuscous. 



Length to tip of elytra 6.50-7 mm.; width 3-3.25 mm. 



Fig. 24 Adult Thionia bullata (Say), enlarged (original). 



Redescribed from a series of both sexes taken by the 

 writer in Mississippi at Longview, June 27, 1920, Port Gib- 

 son, July 22, 1921, and Tupelo, July 1, 1921; a female taken 

 by sweeping grass and low shrubbery in pine flatwoods at 

 Pascagoula, Miss., July 6, 1920. 



Oak is without question the principal host as adults and 

 nymphs of all stages were abundant on this tree in many 

 localities. Hickory is a possible host as the writer took a 

 specimen on this tree at Columbia, South Carolina, Aug. 11, 

 1917.
