grasses, in a river bed near Columbus, Ohio, in May and 

 worked out a partial life history. This is the only hint 

 we have of the habits and early life history of the species 

 of Myndus. 



Key to the species of Myndus 



1. Frons distinctly twice-banded 2. 



Frons not banded 4. 



2. Frons yellowish-white 



Elytra with a fuscous apical vitta along the commissure 



pictifrons Stal 



Elytra sordid, without a vitta, the veins fuscous 



sordidipennis Stal 



Elytra without a vitta, veins pale; smaller and paler than 



sordidipennis 5 mm., delicatus Van D. 



3. Frons greenish-white, a basal and apical fuscous vitta, the latter 



outlined above by a fuscous lunate vitta; elytra varied with 

 fuscous; the lunate vitta lacking in the male lunatus Van D 



4. Frons uniform fulvous-brown; elytra black, a slight orange- 



yellow "Saddle" occupying most of the clavus slossoni Ball 



Frons pale brown; elytra soiled yellowish-testaceous 



enotatus Van D. 



Frons testaceous, usually with a horse-shoe shaped light 



mark impiger Ball 



Frons pale with a black spot on each side of median carina 



at base radicis Osb. 



Frons fulvous, immaculate; elytra hyaline, veins distinctly 



brown occidentalis Van D. 



Frons fulvous, immaculate; elytra hyaline, veins very pale, 



4 mm fulvus Osb. 



Frons dull fulvous, immaculate, with carinae pale; elytra 

 whitish-hyaline, veins pale but distinctly granulated; the 



smallest known species, 3^-4 mm., pusillus Van D. 



Frons pale green, immaculate viridis Ball 



Myndus slossoni BALL 

 (1902 Can. Ent, xxxiv, p. 154) 



The head is proportionately larger (broader) in this 

 form than in any other of our species. There is consider- 

 able variation in the extent of the pale saddle on the dorsal 

 line of the elytra. This pretty species is readily distin- 

 guished by this light yellow or orange saddle. 



Short and stout, black with the margins of the elytra and a 

 median "saddle", light yellow. , 



Vertex, frons, legs and pronotum leather-brown, lighter beneath. 

 Vertex very broad, but slightly carinate, scarcely angled with the
