This bug was taken by T. L. Hankinson June 28, 191 1, in the 

 Bates woods (No. 7678), and July 10 (No. 7693) on the under-

Acanthocerus galeator (Buthoctha) Fabr. (PL LVI, fig. 8.) 



Six large nymphs of this plant-bug were taken on the apical part 

 of a tall herb, AcMnomeris alternifolia Linn., growing in the open 

 glade of the lowland forest (Sta. IV, c; PI. XIV) Aug. 29 (No. 182). 

 This bug has been reported to suck the juice from the plum, and 

 it injures the tender parts of orange plants. Hubbard (Insects Af- 

 fecting the Orange, U. S. Dept. Agr., Div. Ent., p. 163. 1885) gives 

 figures of the adult insect and describes briefly the eggs and young. 

 Forbes and Hart ('00, p. 445) have summarized the little that is 

 known of this insect.

 vegetation (No. 117). It was also taken (Sta. IV) by T. L. Hank-
