There can be little doubt that eugonatus is closely related to the 

 Eiu-opean zonatus Erichson, and I am hiclined to believe they are 

 conspecific, though possibly representing geographical subspecies. 

 Since melampus is related to eugonatus in the same way zonatus is to 

 nigripes (Zetterstedt) , and melampus is indistinguishable from nigripes, 

 it could well be that all these "species" are subspecies or variations of 

 zonatus. 



Ogcodes iOgcodes) melampus Loew 



Oncodes melampus Loew, Berliner Ent. Zeit., vol. 16, p. 60, 1872. 



Ogcodes vielampus, Cole, in part, Trans. Amer. Ent. Soc, vol. 45, p. 61, 1919. —

Sabrosky, Amer. Mid. Nat., vol. 39, p. 424, 1948. 



Diagnosis: Species of group ii. Very similar to the preceding 

 species except that the general habitus of melampus is black instead of 

 brown and the legs are nearly all black. 



Types: 26", 19, co types, California (H. Edwards, MCZ). 



Distribution: This species inhabits the Upper Sonoran and Tran- 

 sition Zones of California, and ranges north through Washington and 

 British Columbia to Alaska. The Minnesota record is the only one 

 east of the Pacific Coast, and indicates that the distribution is prob- 

 ably much wider than is now known (see text fig. 5) . 



Recorded distribution: Alaska, California (Alviso, Santa Cruz 

 Mts., Carrville), Nevada (Ormsby County), and Washington (Mt. 

 Rainier), all recorded by Sabrosky (1948, p. 425).
