LeConte.] 408 [Feb. 1, 
ist. Capron. 5.5 mm.;.22 inch. The prothoracic black stripe extends 
from the base to the tip ; the scutellum is dark, the 6th ventral segment has 
a small rounded pale yellow phosphorescent spot, besides the large one of 
the 4th segment. 
9d. Cedar Keys. 3.8 mm.; ‚15 inch. "The prothoracic black stripe ex- 
tends from the base nearly to the tip ; the scutellum is dark, the epipleure 
are piceo-testaceous, and there is no phosphorescent spot on the 6th 
ventral. ۱ 
85. Ozognathus floridanus, n. sp.—Black, shining, scarcely per- 
ceptibiy and thinly clothed with very short pubescence, punctulate, an- 
tenns and legs piceous. Prothorax twice as wide as long, convex, sides 
margined, very much rounded, hind angles very small, rectangular, 
slightly prominent. Length 1.4 mm.; .05 inch. 
Tampa ; two specimens, one of which was most kindly sent 
me by Mr. Schwarz. The sides of the prothorax are very 
much more rounded than in O. cornutus, and the pubescence 
is much shorter. The $ is not known. 
This is an interesting addition to the genera common to 
Florida or the Antilles and California. 
96. Hemiptychus debilis, n. sp.—Elongate-oval, convex, red- 
brown, shining, clothed with very fine prostrate pubescence, almost imper- 
ceptibly punctulate. Prothorax short, rounded at base, slightly emargi- 
nate at apex, side angles deflexed, sub-acute when viewed laterally. Elytra 
with two deep striz extending from the middle nearly to the apex. Be- 
neath sparsely, finely punctured with sparse shallow punctures on the sides 
in front of the middle. Antenne and tarsi yellowish. Length 1.9 mm. ; 
.075 inch. 
Enterprise; one specimen. Resembles .H. ventralis, but 
the lateral stris: of the elytra are longer, and the surface is 
sparsely covered with shallow punctures at the sides near the 
base ; the form is a little less elongate. 
Hemiptychus similis, n. sp.—Elongate-oval, convex, less rounded 
in frontthan behind, blàckish brown, less shining, finely densely punctu- 
late and finely pubescent. Prothorax more distinctly punctured towards 
the sides. Elytra with two deep strie extending from the middle to near 
the tip ; punctures more distinct at the sidesand in front. Beneath finely 
punetulate. Length 2.3 mm.; .09 inch. 
Tampa و‎ one specimen. 
97. Hemiptychus abbreviatus, n. sp.—Oval, convex, equally 
rounded before and behind, dark-brown, with a slight reddish tinge, im- 
perceptibly punctulate and very finely pubescent. Elytra sparsely, finely

punctulate, strie two, deep, beginning about one-fourth from the apex ; 
the outer one meets a very short trace of the sutural stria ; the inner one is 
shorter than the outer one. Under surface scarcely perceptibly punctulate. 
Length 2.2 mm. ; .085 inch. 
Capron; one specimen. Easily known by the short strie, 
and very fine pubescence. 
88. Hemiptychus auctus, n. sp.—More elongate-oval, convex, 
equally rounded before and behind, sub-opaque, indistinetly punctulate, 
reddish-brown, densely clothed with short, yellowish pubescence. Elytra 
with the outer stria beginning just behind the middle, joining a short rem- 
nant of the sutural stria ; 2d stria beginning farther back, and joining a 
trace of the sub-sutural stria inside of the 2d stria; beginning at the middle, 
and running backwards for a short distance is an indistinct 3d stria, in the 
direction of which is situated a large granule. Beneath indistinctly punc- 
tulate. Length 1.5 mm.; .06 inch. i 
Capron ; one specimen. I do not observe anything similar 
to the granule, or elevated puncture above mentioned in any 
other species. It is situated about one-fifth from the apex. 
The species of Hemiptychus here described are to be inca- 
lated in the table (Proc. Acad. Nat. Se: Phila. 1865, 239), 
between H. ventralis and obsoletus. Several other species al- 
lied to H. gravis, are indicated in the collections of Dr. Horn 
and myself, but until larger series of specimens are obtained, 
I think it is undesirable to describe them. 
89. Catorama punctulata, n. sp, —Elongate-oval, convex, black- 
ish-fuscous, rather shining, thinly clothed with fine, prostrate, very short 
pubescence, distinctly but finely punctured. Beneath similarly punctured, 
antenne and front tarsi yellow-brown. Length 2.5 mm.; .10 inch. 
Tampa; one specimen. The pubescence has a sericeous re- 
flection, where it is well preserved. 
90. Catorama holosericea, n. sp.—Elongate-oval, convex, fus- 
cous, densely clothed with short, gray, erect hair, producing a velvet sil- 
very lustre ; elytra each with a large, oblique spot about the middle, and 
a smaller round posterior one without lustre, and consequently appearing 
darker; surface imperceptibly punctulate. Length 1.5 mm.; .06 inch. 
Enterprise; three specimens. 
91. Catorama minuta, n. sp.—Oval, convex, fuscous brown, uni- 
formly finely punctulate, and thinly clothed with fine pubescence. Length 
1.1 mm.; .045 inch. 
Enterprise ; two specimens. This species is slightly more ro-
