THE CANADIAN ENTOMOLOGIST 251 



Subfamily MiRiN.E. Tribe Myrmecorini. 

 Pithanus maerkelii Herrick-Schaeffer. 



This interesting Mirid was first reported from the United 

 States by Mr. C. E. Olsen (Bull. Brooklyn Ent. Soc.,10 : 34) who 

 took specimens on Long Island, X. Y. A specimen was taken 

 next at White Plains, N. Y., by Mr. Torre Bueno, and during the 

 past year the writer received a specimen from Mr. H. M. Parshley, 

 collected at Eastport, Maine, by Mr. C. W. Johnson. 



The writer took cf , 11 9 's, June 27, 1916, at Honeoye Falls, 

 N. Y., and other specimens were taken at the same time by Mr. 

 Wm. T. Davis who was present on the trip. The species was 

 swept from grasses growing along the edge of land set to nursery 

 stock, and thus may have been imported locally at that place. 

 The writer took one female specimen which had fully developed 

 wings, and this form is, according to Saunders (British Heteroptera, 

 p. 219;, "very rare." 



Species of Doubtful occurrence in North America. 



The writer has recently completed a revision of the genus 

 Lygus, and during the course of researches on the material from 

 North America came to the conclusion that the records of 

 Lygus contaminatus Fallen, Lygus lucorum Meyer, and Lygus 

 viridis Fallen, have been cited in error. In the case of Lygus 

 viridis Reuter (1909), the writer was able to study one of the speci- 

 mens and finds it to be different from the European viridis Fallen: 

 having structural points of difference which will be shown in the forth- 

 coming paper on Lygus. The writer has studied European speci- 

 mens of the above species which were determined by Reuter, and 

 are now to be found in the collection of the U. S. National Museum. 

 The records of contaminatus and lucorum have doubtless been based 

 on certain colour forms of Lygus apicalis which species has a wide 

 distribution in North America. 

 Neobothynotus modestus Wirtner (Ent. News, 28 : 33, 34). 



The writer is unable after a careful study of the literature to 

 find generic points of difference between Neobothynotus Wirtner 

 and Bothynotus Fieber. Furthermore, the description of N. 

 modestus Wirtner does not appear to differ from the description 

 of Bothynotus pilosus Boheman, which species is well described by
