11. Nemicelus marginipennis Lec.—The two sexes differ from 
each other most remarkably and might be easily mistaken for two distinct 
species. The form described by LeConte (Proc. Ac. Nat. Sc. 1854, p.79), 
I take to be the f. The female differs chiefly by the following characters : 
Less elongate, opaque above, color of upper and underside darker. Head 
densely rugosely punctulate with an obtuse tooth behind the eyes, eyes 
smaller, less elongate and less oblique, more convex ; antenne with the 
first joint only one-half longer than wide, shorter than the two following to- 
gether. Thorax hardly longer than wide anteriorly, more dilated in front, 
not emarginate at apex, apical edge thickened, base much less lobed in 
the middle, surface densely rugosely punctulate. Elytra almost entirely 
covering the abdomen, less truncate at apex, distinctly pubescent, densely 
punctulate, stri less evident. Prosternum shining, punctate, process be- 
tween the front coxe hardly visible, propleure opaque, sculptured as the 
thorax; mesosternum much smaller, less broadly rounded in front, dilated 
behind, shining punctate; metasternum and abdomen opaque, the latter 
less elongate, last segment not longer than the preceding with a large shal- 
low impression. Hind tarsi 4-jointed as in the male. | 
The genus Nemicelus was first described by Dr. LeConte, 
and is certainly distinct from Hemipeplus. 
12. Nemicelus microphthalmus, Y n.sp.—Linear, pale, yellow- 
testaceous. Head quadrate, subconvex, behind the eyes straight, then 
suddenly narrowed and forming a short neck, somewhat shining, sparsely 
and obsoletely rugose ; eyes small, round, convex, very coarsely granula- 
ted, mandibles deeply emarginate and black at tip; antenne a little longer 
than head and thorax, first joint stout one-half longer than wide, shorter 
than the two following together, joint 2 globular, the following 4 joints as 
long as wide, equal, 7 and 8 a little larger than the preceding, the three 
last joints abruptly larger, 9 and 10 hardly transverse, terminal joint oval

A single specimen from Enterprise, found in May, attracted 
by the light, is before me, another specimen from Tampa is 
in the cabinet of Dr. LeConte. Smaller and narrower than 
the smallest females of JN. marginipennis and very distinct, 
especlally by the form of the head and by the small, round 
eyes. 
19. Philothermus puberulus, n. sp.—Elongate-elliptical, trans- 
versely convex, dark chestnut-colored, shining, above with distinct, fine, 
erect pubescence and with some longer hairs at the sides. Head sparsely 
punctured, antenne shorter than in Ph. glabriculus, apparently 10-jointed, 
joints 2 and 8 slender, the following six joints small, 7-9 strongly trans- 
verse, joints 10 and 11 forming a solid club as in Cerylon. Thorax less 
transverse and less strongly margined than in Ph. glabrieulus, rounded on 
the sides, moderately sparsely punctured. Scutellum transverse, shining, 
with a few punctures. Elytra strongly striate-punctate, interstices finely, 
sparsely punetulate. Prosternum and propleure distinctly, not densely, 
metasternum and first ventral segment in the middle finely and sparsely, 
at the sides very coarsely punctured, segment 2-4 each with two trans- 
verse rows of strong punctures, last segment more finely punctulate ; legs 
testaceous. Length 2 mm. ; .075 inch. 
Abundant in Florida under old bark of Pinus palustris. 
Smaller, narrower and more convex transversely than P. 
glabriculus, with the sculpture above and beneath stronger and 
at once distinguished by the much more evident pubescence 
and by the form of the antennal club. By this last charac- 
ter Ph. puberulus forms a passage to Cerylon. Sexual charac- 
ters are not evident ; some specimens have the sides of thorax 
less rounded ; these are probably the males. 
acuminate. Thorax but little longer than wide anteriorly, feebly and 
broadly emarginate in front, sides oblique, convergent towards the base, 
subsinuate anteriorly and broadly sinuate before the hind angles ; base al- 
most straight, not lobed, apical edge thickened, anterior angles obtuse; 
rounded at tip, posterior angles obtuse ; surface somewhat shining, indis- 
tinctly, rugosely punctulate with a faint trace of an impressed median line, 
basal impressions large and deep. Scutellum opaque, subquadrate and a little

14. Olibrus princeps, n. sp —.Rounded-oval, pale rufo-testaceous, 
thorax with a large brownish discoidal spot. Elytra black each with a 
large, oval, bright orange-colored spot at the suture before the middle, 
outer half of the basal margin and the lateral margin narrowly, apex 
broader yellow ; very finely striate, strie minutely and remotely punctu- 
broader behind, apical side rounded, Elytra almost covering the abdomen, late, interstices obsoletely sparsely punctulate, punctures more distinct 
subopaque, paler than the head and thorax, darker at the sides and with a \ near the lateral margin. The sutural stria alone is deeper impressed ; mes-
