the posterior edge, which is raised : elytra punctate-striate, the interstices fine, 

 convex and transversely rugose : beneath blackish ; feet dull brownish. 



3. U. trilineatus. Black; elytra with three longitudinal raised lines; thorax 

 with the anterior and lateral margins yellowish. 2 1. long ; less than 1 1. wide. 

 Pennsylvania. 



Black, with a reddish-brown tinge: head piceous ; mouth dull testaceous: 

 antenna; blackish, not compressed, with three basal joints piceous, second joint 

 half as long as the third, which is somewhat shorter than the fourth, tho latter 

 and fifth sub-equal : thorax as in the preceding species, but the anterior margin 

 is also yellow, and the edge obtusely rounded ; the medial groove distinct and 

 nearly entire : elytra black, with a tinge of reddish, and with the anterior lateral 

 fourth obsoletely rufo-piceous; each elytrum with three longitudinal raised lines; 

 lateral edges and suture raised ; beneath and feet blackish. The obtusely round- 

 ed anterior margin of the thorax, and the peculiar sculpture of the elytra, serve 

 to distinguish this species from the preceding. 



Lychnuius, Dej. Catal 



L. morio. Black; lateral thoracic margins dull testaceous; elytra four-ribbed. 

 5J I. long; 2 1. wide. Pennsylvania. 



Black or black-brown ; antenna compressed, black-brown, with the joints sub- 

 equal: thorax inequal.or each side of the middle impressed; triangular, with tho 

 sides slightly sinuated a little behind the apex, which is acutely rounded : minute- 

 ly and densely wrinkled, black, with the anterior and lateral, margins dull tes- 

 taceous : scutel acute-triangular : elytra finely granulate or shagreened with four 

 or rather five longitudinal raised lines, which are more or less abbreviated before 

 the apex : beneath and feet black, with the terminal ventral segment dull testa- 

 ceous. Form and size of hampyris laticornis, Fab., to which it is closely 

 allied, but it differs from it in having the apex of the thorax more acutely round- 

 eJ; in the lateral margins being less broadly testaceous, the disk more inequal, 

 and in the raised lines of the elytra being more distinctly defined. 



Ellychnia, Dej. Catal. 



E. autumnalis. Black-brown ; sub-margins of the thorax whitish, with a ro- 

 saceous spot. 4 j I, long; 2 1. wide. Pennsylvania. 



Lampyris autumnalis, Melsh. Catal. 



Oblong-oval, black-brown ; antennas moderately compressed, subfiliform, black, 

 with the second joint about half as long as the third : thorax semioval, confertly 

 and minutely wrinkled, with the disk suborbicular-convex, black, glossy ; sub- 

 margins whitish, with an oblong rosaceous spot; exterior margins black and not 

 attaining the apex; basal edge very slightly sinuate; scutel glabrous; elytra 

 finely shagreened, with about three obsolete, longitudinal raised lines ; beneath 

 and feet black ; pleurae within the margins whitish, tinged with rosaceous. 

 Bears a resemblance, in the dispositions of the colors of the thorax, to Lampyris 

 corrusca, Fabr., but it can hardly be confounded with that species, as itis almost 

 three times smaller, and has the elytral lines obsolete. It also resembles I.. 

 nigricans, Say, but apart of inferiority of size, it differs from that species in 

 having the lateral thoracic margins exteriorly black, and the disk orbicular-con-
