ular and sparsly punctured ; elytra dull reddish 
brown, with a slight perlaeeous reflection ; striae 
well indented, impunctured ; interstitial spaces 
depressed, third space with an impressed punc- 
ture beyond the middle : feet yellowish piceous, 
posterior pair darker. 
Length less than three-tenths of an inch. 
Much like the parmatus. Say, it is more slen- 
der. 
FERONIA, Latr. Dej. 
(Poccilus, Bon.) 
1. convexicollis. Say. Resembles F. chalci- 
tes, Say, but is shorter, the thorax more convex, 
and the punctures of the third interstitial striae 
of the elytra are three, of which the terminal is 
near the tip. 
(Steropus, Meg.) 
2. F. ohsoleta^ Blackish-ferruginous ; elytra, 
striae obsolete each side and at tip. 
Inhab. Indiana. 
Body very dark rufous, polished : lahrum^ pal- 
pi^ mandibles at base, antennae, feet and abdomen 
honey -yellow : head impunctured ; a slight rais- 
ed line over the antennae, inside of which the 
front is slightly corrugated transversely each 
side : thorax with the surface obsoletely corru- 
gated, visible in a particular direction ; dorsal 
line acute, slightly impressed ; basal lines in- 
dented, single, viewed from above orbicular, de- 
finitely and rather deeply impressed ; base a 
little emarginate,. not wider than the abdomi- 
nal petiole ; elytra with punctured, not deeply 
impressed striae, obsolete at tip and on each side ; 
marginal ocellate punctures about seventeen, in 
a continuous series rather sparse in the middle ; 
near the tip very slightly sinuated ; third inter- 
stitial space with a puncture near the middle of 
the second stria. 
Length two-fifths of an inch. 
Closely allied to S. illigeri, Panz.,butthe tho- 
rax of that species is not so narrow at base, and 
its elytral striae are not obsolete at tip, and not 
even decidedly so on the sides. It is exceeding- 
ly like S. ventralis, N., but it is more robust and 
the sides of the elytra are more arquated. 
The characters of this species agree very well 
with the description of tenebricosa, Dej., except- 
ing that the elytra are not “ assez fortement sin- 
uees posterieurement.” 
3. F. obscura. Black ; tibiae and tarsi dark 
rufous ; elytral striae obsolete each side. 
Inhab. Indiana. 
Body black ; labrum and base of mandibles 
tinged with rufous : palpi dull honey -yellow : 
antenncB blackish-ferruginous: front with two 
indented lines : head impunctured : thorax not so 
narrow at base as the petiole ; dorsal line acute, 
not deeply impressed ; basal lines well indented, 
definite, impunctured, not orbicular viewed in 
any direction, very slightly arquated ; elytra Bin-
