Both the styles, connective and oedagus of this species are so en- 

 tirely different from the corresponding parts in the two preceding 

 species that it does not seem possible that they could be members 

 of the same genus. 



Distribution. This species occurs abundantly in the Southern 

 states and in more limited numbers as far north as Connecticut, and 

 Canada in the East and Montana in the West. It has been reported 

 from Florida, Virginia, Pennsylvania, Georgia, Missouri, Texas, 

 Iowa, Montana, Colorado, New York, Connecticut, New Jersey, 

 Ottawa, Can., Utah, Arizona, Mississippi, Tennessee, Alabama, 

 North Carolina, Louisiana, Kansas, Iowa, Lower California, Mex- 

 ico, and the West Indies. 



Hosts. Wildermuth records this species from the following hosts: 

 Alfalfa, cowpeas, tomato, almond, Bermuda grass, Johnson grass, 

 wheat, barley, oats, bur clover, yellow sweet clover, soy beans, red 

 clover, vetch, Hordeum murinum, beans, sunflower, cocklebur, 

 Erigeron canadensis, mesquite, cottonwood, Sporobolus airodes and 

 Trichlaris mendocina. 



Genus Acutalis Fairmaire. 

 In this genus are small species with the prothorax dark and with 

 five apical cells in the tegmina, the veins of which are quite distinct. 

 A single species is reported from Kansas.

Funkhouser gives the following technical description: 



Small elongate species, very black, with eyes, undersurface of body and in 

 some cases lateral margins of pronotum white, apices of tegmina abruptly 

 hyaline. 



Head twice as broad as long, densely black, smooth, not punctate nor pu- 

 bescent; eyes prominent and white; ocelli small, white, about equidistant 

 from each other and from the eyes; clypeus foreshortened, smooth, extending 

 only slightly in a semicircular curve below inferior line of face. 



Pronotum intensely black above, finely punctate, not pubescent, lateral 

 margins and tip of posterior process in some cases marked with white; dorsal 

 crest low, weakly convex; posterior process nearly straight, slightly decurved, 

 more or less tectiform, extending beyond abdomen and almost to end of apical 

 cells of tegmina, but not reaching apex of hyaline border. 



Tegmina opaque black for basal two-thirds, apical third suddenly hyaline;
