1920] Ball: Review of the Genus Gypona 93- 



shorter and less angled and the front is distinctly shorter and 

 broader. The females are usually much longer and lighter 

 colored than the males, grayish cinereous with minute fuscous 

 spotting. The males are usually heavily irrorate, with fine 

 brown points on vertex and pronotum, while the elytra are 

 brown with the veins lighter and milky spots irregularly dis- 

 tributed in the cells. 



This species occurs along the Atlantic and Gulf coast from 

 Connecticut to Texas and Mexico. It does not seem to be a 

 common species far inland, except possibly in the South. A 

 single male from Chicago has been examined. It is probable 

 that the eastern records for cinerea all belong to this species 

 and that these two species scarcely if at all overlap in range. 



3. Gypona (Prairiana) fraudulenta Spangb. 



Gypona marmorata Fowl. 



Resembling miliaris in general form, but with the ocelli 

 widely separated, and the antennal sockets touching the eyes. 

 Golden yellow, heavily ornamented with brown and fuscous as 

 follows: A line under the vertex margin, a pair of round spots 

 on the vertex behind the ocelli, irregular markings on the anterior 

 portion of the pronotum, two lines on the scutellum and 

 irregular lines in the areoles. A single female from Glen Echo, 

 jyiaryland, is at hand. 



This species is somewhat intermediate in character between 

 Gypona and Prairiana, but until the whole group is worked up 

 and- its affinities established, it should remain in the latter 

 genus. 



Spangberg, page 59, of Species Gyponee, describes a species 

 as marmorata that is quite different from the one Fowler 

 described so his name would fall in any case. 



Subgenus Ponana n. sub. gen. 



Resembling Gypona in general appearance, the body inclined 

 to be cylindrical rather than so definitely flattened. Vertex 

 often much shorter than wide, usually convex, with a rather 

 definite depression before the thickened anterior margin, which 

 is usually indicated above and below, but not produced more 

 than its own width. Vertex and front meeting in nearly a 

 right angle. Ocelli on the disc before the middle. Elytra 

 long and narrow, closely folded. Venation regular.
