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. 

 h y b r i d a Er., (Ins. DeutschL 75) but that is an elongated species with a dis- 

 tinctly punctured thorax. 



6. A.obsoleta, rotundata, convexa, rufa, thorace lateribus rotundati?, basi 

 truncata vix sinuata, subtilissime parce punctulato, elytris subtiliter punctato- 

 striatis, interstitiis obsoletissime punctulatis, 3io parce punctato. Long. '075.

Pennsylvania : for a typical specimen I am indebted to Dr. Melsheimer. His 

 description difFcfrs 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.

1. C. eg en a, subglobosa, testacea nitida, parce subtilissime punctulata, 

 elytris subtiliter striato-punctatis, tibiis posticis valde 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 el3'^tra 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 

 g 1 o b o s a, on more close examination proves to belong to Liodes. 



COLENIS -Er. 



1. C. impunctata, subglobosa, testacea, nitida, thorace Inevissimo, elytris 

 impunclatis, transversim obsoletissime strlgosis, 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 aie 

 alike in all, they are probably females. This species will be easily distinguished 

 from the European C. d e n t i p e s 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 antennae 

 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 ? 1 aev i s , globosa, nigra, nitida lasvis, 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 antennas it appears to belong to this genus ; 

 the club of the antennae 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 equal in 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 tibiae 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 striae or
