THE ZOOLOGIST. 



Addenda. 



There are a few American species of Rhynchota, with whose 

 classified position I was not sufficiently familiar to place them in 

 the body of my paper; thanks to Mr. A. Butler and the Editor, 

 however, I am now enabled to refer them to their approximate 

 situations.! 



Brochymena arbor ea, Say.* 

 Trissolcus brochymence is given as preying upon this species, 

 of whose position I am still uncertain (though Brochymena is a 

 genus of Pentatomids), by Ashmead (Florida Agric. 1881, p. 193). 



Euschistus servns, Say.* 

 From this Pentatomid, Ashmead has recorded (Bull. U. S. 

 Nat. Mus. 1893, p. 162) his Proctotrypid Trissolcus euschisti. 



Murgantia histrionica, Hahn.* 



This is another Pentatomid, from which the same author 

 (loc. cit. p. 163) records his Trissolcus murgantice. 



Acanthocerus galeator y Fabr.* 

 Some doubt exists respecting the parasitism of Hadronotus 

 rugosus, How., upon this Coreid, as given by Ashmead (L c, 

 p. 232). 



Acanthocephala femorata, Fabiv ;: 



This Coreid is destroyed by Hadronotus floridanus, Ashm. 

 (Amer. Entom. 1887, p. 148 ; cf. also D. T. Cat. v. 498). 



Anasa tristis, DeG.* 

 Two species of the Proctotrypid genus Hadronotus attack 

 this Coreid ; H. anasce is reported from it by Ashmead (Bull. 

 Ent. U. S. Dept. Agric. 1887, p. 23), and Dalla Torre tells us 

 (Cat. v. 498-9) that Riley and Howard have raised both this 

 species and H. rugosus, How. 



f It is not within my province to investigate the error which led Dalla 

 Torre to insert (Cat. v. 67) Misocampus nigricornis as the Khynchotal host 

 of Eulophus verbasci. It is, of course, itself a Chalcid of the genus Tory- 

 mus as placed by D. T. himself (lib. cit. 310). That notice should be drawn, 

 however, is necessary, since the statement is copied by de Gaulle (Cat. Hym. 

 France, 109).
