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). 



^.Length, 7.1 mm.; width, 

 2.54 mm. Deep carmine red, 

 fuscous on the scutellum and 

 bordering the commissure of 

 the hemelytra; not so broadly 

 fuscous on the cerium 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 L length, 

 .65 mm.; width, .17 mm.; H, 

 2.42 mm.; greatest width, .14 

 mm.; incrassate, tapering from 

 the middle toward the apex; 

 III, 1.60 mm., linear and slen- 

 der; IV, .60 mm.; black, the 

 -first two segments clothed with 

 prominent coarse hairs; almost 

 identical in structure to cacsar. 

 9 . Structurally and in color 

 very similar to the male; no 

 antennal differences between the sexes. Very hard to distinguish 

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

 ing on the scutellum. 



In Missouri the species was found breeding on witch-hazel 

 {Hamamclis virg'uuana) and probably has the same food plant 

 in the northern localities.
