181. Quedius fulgidus Fab., mesomelinus Marsh, groeiilandicus Zett., iracundns 



Say, erythrogaster, melanocephahis Mann., sylvicola Casey. Systematists 

 are not in full accord as to the specific values of the above forms. Omit- 

 tiiig mesomelinus. Dr. Geo. H. Horn refers them to one variable species. 

 T. viii, 158; Eut. Auier. i, 109. Mr. A. Fauvel disposes of them thus: 



Q. fulgidus Fab., iracftHcZits Say. — All North America from Discovery Bay 

 near lat. 83°, and Greenland to Louisiana; Canaries, Europe, Barbary, 

 Asia Minor. Siberia, uortheru India, Java, Australia, Tasmania. New 

 Zealand. 



Q. mesomelinus Marsh, groenlandicus Zett. — Greenland, Canada, Maine, 

 Massachusetts, New York, Ohio, Nevada, Oregon, California, etc.; Peru, 

 Australia, New York, Europe. 



182. Q. erythrogaster Mann., from Sitkha, California and Nevada, he regards 



as a valid species. Melanocephalus and sylvicola he had not seen. To 

 preserve uniformity in the Lists two species are tabulated as in Cat. iv, 

 but from an examination of examples of iracundus Say taken here in 

 Pennsylvania, and erythrognster from Queen Charlotte Island, B. C, 

 apart from color, I can see no permanent differential characters and the 

 differences as such seem to indicate variations rather than races. 



183. Q. Isevigatus Gyll., plugiatus, longipennis Mann., rufipennis Maek. — Like- 



wise variable in color. "From Alaska to Oregon, Kansas, Canada and 

 Pennsylvania," Horn. California, Nevada, Georgia. I take it here, and 

 have it from Illinois and Michigan ; Massachusetts, Blanchard ; Veta
