The wings of the only specimen at hand are rather broader than usual in the genus, 

 approaching somewhat those of A. luteola in form, but otherwise the insect resembles 

 A. ramona."]

 Hab. Noeth America 1 2 , Northern California, on Pacific coast northward to Alaska 

 (coll. L. Bruner). 



Not having access to Scudder's original description of this species, it has been a 

 difficult matter for me to decide definitely as to the insect there described. Then, too, 

 no Arphia? are at hand from the extreme north, hence the selection of the form now 

 under consideration has been made somewhat arbitrarily.]

Arphia behrensi, Sauss. Prodr. (Edip. pp. 71, 72 (1884) \

 Hab. Noeth Ameeica, California x (coll. Calif. Acad. Sciences). — Mexico (Saussure). 



Saussure's description of this insect as it appears in the ' Prodromus CEdipodiorum ' — 

 "Antenna? breviusculse. Vertices scutellum 2 6 piriforme quam latius longius. 

 Caput et pronotum crassius granosa ; crista pronoti incisa," — taken together with the 

 place to which it is assigned in his synoptic table of the species, makes it necessary to 

 settle on the insect now chosen to represent A. behrensi. Then, too, since it was 

 named in honour of James Behrens, of San Francisco, California, we can hardly do 

 otherwise, even though two or three other forms were included as varieties. Possibly 

 both A. ramona, Eehn, and A. decepta, here described, were referred to as such varieties 

 (see notes under those species).
