a shallow, rounded impression between the eyes. Prothorax longer than 
wide, sides slightly rounded, near the apex and base, hind angles rectangu- 
lar, rounded at the extreme tip, finely not densely punctured, with a few 
erect hairs towards the sides, base not margined. Elytra finely not densely 
punctured, punctures here and there, forming rows (but not indicating 
strie); there are some erect hairs, especially near the tip, and at the sides. 
Pygidium sparsely punctured. Beneath punctured, last ventral segment 
not impressed. Length 2.5 mm.; .10 inch. 
Florida, Georgia and South Carolina; under pine bark. I 
have adopted the name which it bears in the collection of 
Dr. Zimmermann. This species is more slender than H#. par- 
allelus, and difters by the sparse, erect hairs, by the punctures 
of the elytra being less fine and more distant, and by the 
pygidium being sparsely punctured. In these respects it 
agrees with /Z. thoracicus, but difters in color, and by having 
fewer erect hairs. 
Three new species remain in my collection, which may be 
described on the present occasion ; the subjoined table gives 
the essential characters of all the species in our fauna. 
124. Hypophieeus substriatus, n. sp.—Very dark-brown, cylin- 
drical, Jess convex than the other species. Head punctured, transverse line 
well impressed, vertex with a faint, transverse impression, anterior to 
which the surface is more convex. Prothorax scarcely longer than wide, 
punctured, side margin stronger than in the other species, base margined, 
Elytra rather strengly punctured, punctures in rows except near the sides 
and tips, without hairs. Pygidium densely, finely punctured. Beneath 
punctured; last ventral segment broadly impressed, apical part convex. 
Length 4.2 mm.; .18 inch. 
Oregon ; collected by Lord Walsingham. Much larger 
than H. parallelus, and easily distinguished by the less con- 
vex form, more strongly margined prothorax, and by the 
elytral punctures being stronger, and placed in rows. 
125. Hypophleeus opaculus, n. sp.—Cylindrical, convex, biack- 
ish, not shining. Head feebly punctulate, transverse line bounded behind 
by an obtuse, transverse ridge ; epistome convex. Prothorax a little wider 
than long, sides broadly rounded, apex not emarginate, sides very finely 
margined, base indistinctly margined, surface finely, rather densely punc- 
tured. Elytra finely punctured, punctures here and there in rows. Py- 
gidium densely, finely punctured. Beneath sparsely punctured ; 5th ven- 
tral with a small, apical tubercle. Length 3.2 mm.; .13 inch. 
Southern California; one specimen collected by Mr. Hardy,
