punctulate, striz 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 ou’ er one. Under surface scarcely perceptibly punctulate. 
Length 2.2 mm.; .085 inch. 
Capron; one specimen. Easily known by the short strize, 
and very fine pubescence. 
88. Hemiptychus auctus, n. sp.—More elongate-oval, convex, 
equa'ly rounded before and behind, sub-opaque, indistinctly 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 5d stria, in the 
direction of which is situated a large granule. Beneath indistinctly punc- 
tulate. Length 1.5 mm.; .06 inch. 
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. Sc. Phila. 1865, 239), 
between 7. ventralis and obsoletus. Several other species al- 
hed to HZ. 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 tine pubescence. Length 
1.1 mm.; .045 inch. 
Enterprise ; two specimens. This species is slightly more ro-
