ally changing into the piceous colour of the remainder. Stria? very indistinctly 

 punctured. Third interval with three impressed points rather indistinct. In- 

 habits New York. 



24. Badisteii testaceus. Nob. Length 2 lines ; breadth | lines. 

 Smooth, shining, testaceous, inclining to piceous o n head and elytra : joints of 



the antennae gradually increasing in thickness to the extremity: frontal impres- 

 sions deep and rounded. Thorax obcordate, lengthened, scarcely wider than 

 the head ; anterior angles rounded, posterior acute, anterior transverse impression 

 tolerably marked, posterior one obsolete : longitudinal line well marked and en- 

 tire: basal impressions deep, oblong. Elytra wider than the thorax, parallel, 

 almost plane, deeply striate, stria? impunctured, sides of the strife covered with 

 small transverse wrinkles a little oblique, which cutting the stria?, give them an 

 almost reticulated appearance. Inhabits Pennsylvania. 



25. Badisteii micans. Nob. Length 4 J- lines ; breadth 1| lines. 



Black: head, rhinariurn, and upper lip testaceous, palpi ferruginous, with a 

 black spot on the last joint : antenna? brown, the first two joints rufous : frontal 

 impressions rather larger, distinct : an impressed point near each eye. Thorax 

 plane black, margined with rrddish brown :"the margin sinuate near the posterior 

 angles : base rugous : transverse impressions tolerably distinct. Longitudinal 

 lirje deeply marked. Basal impressions large and deep. Elytra piceous, irri- 

 descent, not sinuate at the extremity ; stria? tolerably deep, impunctured : inter- 

 vals broad and plane. Third interval with two impressed points. Body beneath 

 piceous, legs testaceous. Inhabits Georgia. 



This insect differs very much in its general appearance from all the species of 

 this genus, and it may perhaps be necessary hereafter to separate it from the 

 genus in which I have placed it. 



26. Ootjes picipes. Nob. Length 5h lines ; breadth 2\ lines. 

 Resembles the americanus, but is smaller ; the palpi and antenna? are entirely 



piceous ; the thorax is more convex ; the posterior transverse impression is scarcely 

 visible ; the longitudinal line almost obsolete : basal impressions very shallow and 

 indistinct : the elytra are more deeply striate ; and the stria? are impunctate; the 

 third interval with two impressed points : underside of the body black ; legs 

 piceous. Inhabits Georgia. 



27. PniSTONYcnus americanus. Nob. Length 5 1-6 lines ; breadth 1£ lines. 

 Apterous; black, shining; beneath smooth; palpi, antenna?, and legs dark 



ferruginous ; frontal impressions tolerably deep and slightly rugous ; thorax, ob- 

 long, almost square, wider than the head, narrowed behind, the anterior angles 

 projecting, posterior ones rounded ; covered with very slight transverse undulating 

 wrinkles: lateral margin elevated posteriorly ; the base cut almost square: ante, 

 rior transverse impression small, incurved ; posterior deeply marked ; mesian line 

 deep, abbreviated at each end by the transverse impressions, the anterior of which 

 cuts it at right angles : basal impressions oblong, deep, slightly rugous. 



Elytra wider than the thorax, lightly convex ; not sinuated at the extremity '■> 

 deeply striate; stria? impunctured, with two impressed points on the third inter-
