12 IOWA STUDIES IN NATURAL HISTORY 
(Proc. Ia. Acad. Sei., IV, 231, 1896.) Since that time I have 
not found specimens in the field but in looking over a student 
collection at Ames I discovered a nymph collected at that place 
in the summer of 1915. 
As Van Duzee suggests (l. c.), this species ‘‘is probably con- 
fined to the Mississippi Valley and adjacent fertile plains.’’ 
Stal’s type came from Illinois. So far as I can learn, the only 
other locality records aside from the ones just mentioned are 
those of Uhler for Canada and Nebraska (l. c.) and the more 
recent record of Zimmer for Nebraska. He says (1. c.): ‘‘The 
only addition to this record [Uhler’s] is a single male taken at 
West Point in October, 1884, by L. Bruner.’’ 
Genus CHLOROCHROA Stal 
1872. CHLorocHROA Stal, Svensk. Vet. Handl., 10, no. 4, 33. 
Nine species are placed in this genus; six are found in the 
New World while three are Palaearctic in distribution. In the 
United States the genus apparently reaches its greatest devel- 
opment west of the Missouri river. A single representative has 
been recorded from Iowa. A summation of the principal diag- 
nostic characters includes the following: 
General form broader than Khytidolomia and less produced anteriorly. 
Color clear green. Head and pronotum together forming a shorter and more 
obtuse angle than in that genus, the pronotum more depressed anteriorly. 
Rostrun¥ not extending to posterior coxae, the second segment markedly 
longer than the third, the third and fourth subequal. Antennae long, slendér 
bearing at base a blunt rounded tooth which bears at its base a smaller 
tooth. Buecculae narrow, extending nearly to base of head, expanded into 
rounded flaps anteriorly. Humeral angles rounded, the postero-lateral mar- 
gins nearly straight. Scutellum rather long but proportionately broader 
than in Rhytidolomia. Corium more or less rounded at outer posterior angle. 
Legs furnished with numerous hairs; basal tarsal segment of front legs 
very large, heavy.
