S. neglectus, Mars. Mon., 1855, p. 491, pi. 18, fig. 108. 



Oval, convex, surface distinctly bronzed. Head moderately punc. 

 tured. Thorax moderately coarsely punctured at the sides, more tinely 

 along the apex, and with a few coarse punctures along the basal margin. 

 Elytra rather coarsely, but sparsely punctured, punctures extending 

 sUglitly in front of middle and outside of the first stria to the base ; ex- 

 ternal subhumeral stria not distinct from the marginal, internal moder- 

 ately long joining the humeral ; first dorsal extending slightly beyond 

 the middle, second extending two-thirdSj third and fourth equal to the 

 first, fourth arching at base -with the sutural which is entire. Propy- 

 gidium densely punctured, pygidium more sparsely punctured. Anterior 

 tibia} multidenticulate, middle and hind tibiic spinulose. Length .12 

 inch ; 3 mm. 



This species is closely allied to those of the preceding group, with 

 which it had been associated. The prosternum is, however, acutely 

 carinate. In this species may be seen the rather curious tendency of the 

 striae to be prolonged by smooth lines between the punctures. This 

 character is, however, much better shown in Jimbriatus. 



This species occurs in Georgia. 



S. mbriculus, Mars. Mon., 1855, p. 489, pi. 18, fig. 107. 



Oblong oval, moderately convex, ferruginous brown, shining. Head 

 finely and densely punctured. Thorax sparsely punctured over the entire 

 surface, slightly more densely at the sides. Elytra sparsely punctured, 

 jtunctures coarser in front, and denser at apex, extending slightly in /ront 

 of middle, and also between the striai ; external subhumeral absent, in- 

 ternal short apical ; first dorsal extending two-thirds the length of the 

 elytra, 2-3-4 gradually shorter, the latter arching at base, sutural at- 

 taining the apex interrupted at base, continued by fine punctures to the 

 arch of the fourth dorsal. Pygidium moderately convex densely and 

 moderately coarsely punctured. Anterior tibia; 5-6 denticulate, middle 

 and hind tibite spinulose. Prosternum carinate, striae very indistinct. 

 Prosternal fosste linear uniting at the summit of the carina in front. 

 Length .09 inch ; 2.25 mm. 



The type of this species is before me, and although not properly au- 

 thenticated as far as habitat is concerned, is introduced into the present 

 essay from its decidedly American aspect. From all the species of 

 Saprinus in our fauna it may be distinguished by the curious form of the 

 jirosternal fossae in which the striae terminate. In place of being merely 

 rounded pits as is usual when they occur, these fossae ai'e linear and 

 extend to the summit of the prosternal carina parallel with the anterior 

 margin of the lobe, which is also more prolonged than is usual in the genus. 

 The interrupted sutural stria is also peculiar to this species in the present 

 group.
