arc broadly truncate behind: the Stli stria is entire, and the 9tli continues around the 

 extremity, almost to the sutural stria, as in Lachnophori. The paraglossse are longer 

 than the iigula, and pointed at their extremity: the mentum is not toothed: the palpi arc 

 acuminate a1 tip: the last joint of the maxillaiy palpi is scarcely longer than the preceding. 

 The antenna are filiform, with only the first joint shining: the joints are equal in length 

 excepting the 2d, which is one half shorter. The thorax is rounded, slightly cordate, being 

 narrowed behind, with a short broad lobe at the middle of the base. The feet are Blender, 

 the terminal spurs distinct, the posterior tarsi long. Mazoreue is probably allied to this 

 genus, but I have had no opportunity of examining it, and can only judge by description.

One specimen, New Orleans, Mr. Guex. The margin of the thorax is wider towards 

 the posterior angles and reflexed: the disc is slightly convex, the longitudinal line entire, 

 and the transverse impressions distinct: the elytra are iridescent, about twice as wide as 

 the thorax, and one third longer than wide: they have no scutellar stria: the third inter- 

 stice is bipunctate.

This group approaches the Harpali, but independent of sexual characters, is at once to 

 be distinguished by the glabrous 3d joint of the antenna'. From Pterostichi its separation 

 would appear more difficult; but the impressed labrum and edentate mentum do not oc< ur 

 in that group. 



The first two or three joints of the anterior tarsi of the male are broadly dilated with 

 rounded angles, and covered beneath with a dense brush of hairs. The 8th Btria of the 

 elytra and its punctures arc in the normal position. 



The oid-. ra found in the United State- are Badister, Diplochila, and Dicselus, all of 



which have three joints of the male tarsi dilated: some of the Bpeciea of the first genus 

 have the 3d joint of the antennas hairy, but not rough as in the Harpali. 



To the three species of Badister noted in the fourth volume of the Innate of the Lyceum 

 must be added the two follow ing: 



1. B. maculatus, niger, tlioracc subtransvc : profundi) 



impresso, angolis posticis i lytria Btriatis, interatitiifl fere planis, macula magna hnmerali, 



fascia tenui iutcrrupta pone medium, pedibosqne B I iceifl. Long. '24, 



A single specimen of this pr< tty species, found at Lancaster, Pa., was given me l>\ Mr. 

 S. S. Rathvon. The aides of the thorax are slightly reflexed toward- the posterior am 

 the basal impressions arc small, the posterior transverse one deep. The humeral Bpot ol 

 the elytra is subquadrate, so the anterior third of their disc appears yellow, the suture 

 alone remaining black: the posterior hand i- narrow, and consists of a common rransvi 

 -pot, and a smaller one each side near the lateral margin: the epipleura are dull yellow : 

 the feet are bright yellow, and the palpi testaceous; the antennas are fuscous, with the 

 first joint testaceous.
