veins distinct, broad, and slightly pubescent ; fi\e apical and two discoidal 

 cells; hind wings iridescent. Two anterior pairs of legs broadly spatulate and 

 lightly pubescent at margins; posterior tibiae armed with black-tipped spines; 

 tarsi much produced and lighter in color. Undersurface of body chocolate 

 brown. 



Length: from head to apices of elytra, 5 mm.; from tip of promotal horn 

 to apices of elytra, 8 mm. Width between humeral angles, 2 mm. 



Internal male genitalia. Styles with long flattened anterior proc- 

 ess, widest apically, with a distinct prominence at attachment to 

 connective, caudad of which they are peculiarly wrinkled and show 

 a small but distinct mesal lobe, then widest just caudad of wrinkled 

 portion, after which they curve laterad, ending in a doubly pointed 

 apex, of which the terminal tooth is larger and more slender than 

 the anterior one, the apical third of the styles bearing a few short 

 hairs; connective short and wide, basal half with a heavily chitinized 

 and flattened V-shaped portion; oedagus, viewed laterally, stout and 

 broadly V-shaped, widest at the distinctly notched base, the upper 

 basal process also slightly notched, narrowest at the bend and then 

 widening till near the apex, the caudo-dorsal portion of which is only 

 slightly chitinized, the functional orifice being at about the middle 

 of this slightly chitinized area, the upper portion of the apex bearing 

 a few distinct file-like teeth. 



Distribution. Van Duzee gives the following distribution for this 

 species: Ontario, Maine, Vermont, New York, New Jersey, Penn- 

 sylvania, North Carolina, Illinois, Iowa, Kansas, Missouri, Colo- 

 rado, Wyoming, Montana, Texas, New Mexico, Arizona, and Cali- 

 fornia. Osborn reports it from Florida. It is thus seen to extend 

 throughout the United States. 



In Kansas specimens have been taken in the following counties: 

 Douglas, Ottawa, Pratt, Hodgeman, Clark, Pottawatomie, Labette, 

 Bourbon, Wabaunsee, Russell. Riley, Ellis, Ellsworth and Wyan- 

 dotte. 



Hosts. Funkhouser gives the following hosts for this species: 

 Aster, daisy, joe-pye weed, alfalfa, prickly lettuce, wild carrot. 

 Miss Branch mentions golden rod and sensitive rose. Gillette and 

 Baker report it from Glycyrrhiza lepidota, Psoralea tenuijiora and 

 Apocynimi androsacniifolium. The writer has found it very abun- 

 dantly on alfalfa. 



Genus Enchenopa Amyot & Serville. 

 But two members of this genus are known to occur in the United 

 States. The widely distributed E. binotata occurs in Kansas.
