Marquette, Lake Superior. The punctures of the entire 
surface are coarser than in any other of our species. It must 
be considered the intermediate form between those with the 
long and those with the broad thorax. 
34. Pedilophorus subcanus. Longer-oval, convex, rounded be- 
hind, obliquely narrowed in front of the elytra, black, irregularly mot- 
tled with very short gray pubescence like hoar frost, and thinly clothed 
with short erect black bristles. Beneath finely, densely punctured, finely 
pubescent, legs piceous; tarsi paler, fourth joint with a long lobe. 
Length 4.4 mm ; .17 inch. 
Escanaba, Lake Superior. In form and pubescence this 
species resemembles Byrrhus, but the tarsal lobe requires its 
reference to the present genus, with which it also agrees in 
having the mandibles not covered by the prosternum in re- 
pose. 
35. Paromalus teres. Cylindrical, but not slender, shining black ; 
head and prothorax punctulate, elytra finely not densely punctured, each 
with faint traces of two oblique striz near the base; sutural stria want- 
ing. Pygidium very finely punctulate, under surface finely and sparsely 
punctured ; mesosternum emarginate in front, marked with a fine lateral 
line ; prosternum flattened without striz. Length 2 mm ; .08 inch. 
Sault St. Marie ; one specimen. This species only differs 
from P. seminulum by the cylindrical form, in which it de- 
ceptively resembles Teretrius americanus; by having the ely- 
tra more finely punctured, and by the entire absence of the 
sutural stria. 
The following species may be conveniently described on 
the present occasion. 
36. Hetzrius Blanchardi. Oval-quadrate, brown, shining, of the 
same form as H. brunneipennis, sparsely pilose with long slender sub-erect 
yellowish hairs. Head opaque, finely punctulate, broadly concave. Pro- 
thorax with the sides slightly nicked at the middle, lateral lobes of the 
dise obsoletely punctulate, divided behind the middle by a transverse 
groove, hinder part deeply margined on both sides ; the impressed groove 
separating the lateral lobe from the disc is much deeper and broader at 
the base. Elytra with three very fine striz, the inner one effaced behind 
the middle. Pygidium opaque, very finely and densely punctulate. Pros- 
ternum narrow, flat, densely punctulate, lateral edges well defined. Length 
2mm; .08 inch,

chard, to whom I dedicate it with much pleasure, asa mark
