Le Conte, Agassiz’? Lake Superior, 221. 
One specimen from Eagle Harbor. This species is remarkable for the sculp- 
ture of the elytra; the punctures of the interstitial spaces are almost invisible, 
and are usually placed in the transverse scratches ; the sutural stria is deeply im- 
pressed posteriorly. By its sculpture this species is nearly related to A. 
hybrida Er., (Ins. Deutschl. 75) but that is an elongated species with a dis- 
tinctly punctured thorax. 
6. A.obsoleta, rotundata, convexa, rufa, thorace lateribus rotundatis, basi 
truncata vix sinuata, subtilissime parce punctulato, elytris subtiliter punctato- 
striatis, interstitiis obsoletissime punctulatis, 3i0 parce punctato. Long. -075.

Pennsylvania: for a typical specimen I am indebted to Dr. Melsheimer. His 
description differs somewhat from the one here given,as the power of the lens 
used by him was not sufficient to enable the specific characters to be clearly 
perceived. 
Cyrtusa Er. 
1. C.egena, subglobosa, testacea nitida, parce subtilissime punctulata, 
elytris subtiliter striato-punctatis, tibiis posticis vaide dilatatis. Long. -05. 
Two specimens from Habersham county, Georgia. This species agrees in 
every particular with the description of C. latipes Er., (Deutschl. Ins. 80) 
except that the thorax is more distinctly punctured at the sides; the sutural stria 
is impressed from the middle of the elytra to the tip. The posterior femora of 
the male are armed beneath, at the extremity, with a very large, slightly re- 
curved tooth, as in C. latipes. 
The insect described by me in Agassiz? Lake Superior, as Cyrtusa 
globosa, on more close examination proves to belong to Liodes. 
Cotents Er. 
1. C.impunctata, subglobosa, testacea, nitida, thorace levissimo, elytris 
impunctatis, transversim obsoletissime strigosis, stria suturali pone medium dis- 
tincta. Long. -03—-:05. 
Two specimens, found in Pennsylvania, were given me by Mr. Ziegier, a 
much smaller one was found by me in upper Georgia ; as the posterior thighs are 
alike in all, they are probably females. This species will be easily distinguished 
from the European C.dentipes Er., (Deutschl. Ins. 83) by the thorax being 
smooth and shining, even when viewed with a Stanhope lens, and by the entire 
absence of punctures on the elytra. 
The genus will be easily distinguished by the seventh joint of the antenne 
being but little larger than the 8th, so that the club appears 3-jointed, the third 
joint is as long as the second; the middle and posterior tarsi are four-jointed. 
2. C?lxvis, globosa, nigra, nitida levis, thorace margine omni diaphano, 
elytris stria suturali nulla, ore antennarum basi corporeque subtus rufis, metas- 
terno medio nigro. Long. -04. | 
Georgia. I considered this little insect as anon-globatile Agathidium, but on 
relaxing a specimen and examining the antenne it appears to belong to this genus ; 
the club of the antennez is, however, more slender than in the preceding, so that 
the seventh joint really appears to enter into the club. The third to the sixth 
joints are equalin length. The anterior margin of the front is broadly rounded, 
as in the preceding genus. The mesosternum is strongly carinate. I cannot be 
absolutely certain that the posterior tarsi are not 3-jointed, in which case it 
would be necessary to place it in Agaricophagus ; the tibie are apparently with- 
out spines. | 
The head is fully one-half as wide as the base of the thorax, and black, with 
the mouth yellowish. The thorax is very short, deeply emarginate in front, 
slightly rounded on the sides, broadly rounded at the base; the sides and basal 
margin are diaphanous and yellowish. The elytra are entirely without strie or
