A. (lensns Lee. Proc. Am. Philos. Soc. 1878, p. 387. — Black, shining. 

 Seutellum with numerous punctures. Elytra slightly longer than wide con- 

 jointly, surface slightly more finely and a little more densely punctured than 

 in 2y)'onus. Antennse piceous, last two joints somewhat paler. Legs yellowish 

 testaceous. Length .28 inch ; 7 mm. 



This species is also closely related to jn-onus but may be distinct. 

 The punctuatioQ of the scutelluin cannot be depended upon in the 

 separation of this species from the preceding, nor can too much stress 

 be laid upon the elytral sculpture, this also being a variable character. 

 I have seen in Mr. Ulke's cabinet a specimen from Maryland, very 

 nearly intermediate between pro?n/s and dcjisu^:, with however a little 

 more resemblance to the latter in elytral sculpture. Until we have 

 more specimens it will be better to retain this species as distinct, while 

 Jiavirollis might be placed as a color variation of pronus. 



Occui-3 in Florida and Maryland. 



A. flavipes Lee, loc. cit. — Black, shining. Head with very few punc- 

 tures at the side behind the eyes. Antennse stouter externally, the last five 

 joints as broad or broader than long. Elytra punctured as in pronus, the 

 jjunctures however relatively longer and less closely approximated. Legs 

 testaceous. Length .18 inch; 4.5 mm. 



This species is very distinct ixom pronus by the characters afforded 

 by the head and antennae, the form is apparently more slender but 

 this is deceptive. 



One specimen, Florida. 



HETEROTHOPS Steph. 



The head in our species has on each side either three or four 

 punctures arranged in nearly a straight line, the anterior being nearly 

 at the middle of the margin of the eye ; behind the eye are a few 

 small setigerous punctures. 



The palpi, both labial and maxillary have the last joint subulate. 



The thorax has in front two punctures on the disc and two smaller 

 at the apical margin. 



The sexual characters are as in Quedius, the sixth abdominal seg- 

 ment emarginate in the male. The tarsi are dilated in both sexes 

 nearly equally. 



The color varies greatly among the individuals of a species, so that 

 names have been given to color variations. 



There seem to be but two species in our fauna distinguished by the 

 following characters : 



Third joint of the antennse as long as the second, eleventh not longer than 

 the two preceding together, head with four punctures on each side.
