Lopidea reuteri new species. (Fig. 5.) 



Very close to cacsar in size and color but differing greatly 

 in the form of the male genital claspers (fig. 5). 



rj . Length, 7.1 mm.: width, 

 2.54 mm. Deep carmine red, 

 fuscous on the scute! him and 

 ps bordering the commissure of 

 the hemelytra; not so broadly 

 fuscous on the corium and cu- 

 neus as in cacsar. Head mostly 

 black, calli fuscous. Legs 

 black; sternum, genital seg- 

 ment and usually the low- 

 er side of three adjoining seg- 

 ments blackish. 



Antennae: segment I, length, 

 .65 mm.j width. .17 mm.; II, 

 2.42 mm.; greatest width, .14 

 mm.; incrassate, tapering from 

 the middle toward the apex: 

 III, 1.60 mm., linear and slen-

 Fig. $.-Lo/>idea reuteri, male genital claspers. prominent coarse hairs: almost 



,, tight clasper, lateral aspect. identical in structure to cacxar. 



b right clasper, dorsal aspect. 



c left clasper, ventral aspect. 9. Structurally and ill colr 



d left clasper, dorsal aspect. . ., 



very similar to the male; no 



antennal differences between the sexes. Very hard to distinguish 

 from the female of cacsur, which species usually has less fuscous shad- 

 ing on the scutellum. 



In Missouri the species was found breeding on witch-ha/.-l 

 (Hamamclis rin/itiiiina*) and probably has the same food plant 

 in the northern localities.
