Geographic range : British America, Fabricius 1781, p. 418 ; appears 

 to be a more northern species in its range than U. flnripcniiis though 

 they are often taken in same localities.

Cimhvx aincricaiHi Leach. (Det. T. & C). Taken in rock clearing near 

 water's edge on north side Conglomerate bay (106) ; also one larva in 

 alcohol which may belong to this or the next species. 



Geographic range : The earliest record for this species is Abbot 

 1792, plate 61, under the name of fcmorata Linne. Leach described it 

 in 1817, p. 33, and since that time many authors have written upon 

 the species which is rather a common insect throughout most of the 

 regions in Xorth America where willows are found. The larva of this 

 and probably the following species feed on willow leaves.
