Dicosmcecus atripes (Hagen), 1875, p. 600. (Platyphylax) 
Lectotype, male. — Colorado Mts., August 1873, Comporte.

Dicosmcecus gilvipes (Hagen), 1875, p. 601. {Stenophylax) 
Lectotype , male. — Quesnel Lake, British Columbia, August 
27, Crotch. No. 10716. 
The genitalia of this type are identical with those of atripes 
(Hagen) . The color of the legs, previously used to separate 
the two, was found to vary over a large series of specimens. 
Gilvipes, therefore, becomes a synonym of atripes.
