All North American specimens of this 
species are referable to the variety lateralis 
Hahn (1834, p. 85). The typical unifascia- 
tus has the pale areas broader than does uni- 
fasciatus lateralis; the embolium and corium 
of this variety are pale brown except for 
a small fuscous patch on the apical area of 
the corium. 
Foop PLant.—Northern bedstraw (Ga- 
lium boreale). 
- Known DistrisutTion.—This is a Eu- 
ropean species, now known from Alberta, 
British Columbia, Colorado, Illinois, Iowa, 
Maine, Minnesota, New York, North Da- 
kota, Nova Scotia, Quebec.  Blatchley 
(19264, p. 737) records this from Cham- 
paign, Ill., June 14, at light, under the name 
Polymerus unifasciatus (Fabricius). Speci- 
mens of the typical form from North Amer- 
ica have not been seen by the writer.

Polymerus illini new species 
This differs from flavocostatus Knight by 
the longer rostrum, and from punctipes 
Knight by the black tibiae, the partly black 
femora and the red orange cuneus.

Mave.—Length 4.85, width 2.50. Head 
width 1.18, vertex 0.44; black, a glabrous, 
pale spot either side of vertex. Rostrum, 
length 1.43, just attaining posterior margin 
of mesosternum. Antennae black with last

and ventral edge pale. Clothed with silvery, 
sericeous pubescence intermixed on hemely- 
tra with simple, black pubescence. General

Polymerus proximus Knight 
Polymerus proximus Knight (19234, p. 601). 
This is closely related to migritus 
(Fallen), but may be distinguished from it 
by the uniformly dark tibiae; the length of 
the first antennal segment is equal to the 
width of the vertex, while in nigritus the 
length of the first segment is less than the 
width of the vertex. 
Mate.—Length 5.30, width 2.70. Head 
mostly black with a yellow spot on either 
side of vertex near eye. Rostrum barely at- 
taining hind margins of middle coxae. An- 
tennae, first segment black; second very 
dark brown, black at base; third dark 
brown; fourth black. Pronotum with pos- 
terior half of disk strongly convex, trans- 
versely wrinkled, uniformly black, slightly
