the ordinary subrecumbent pubescence. In the form of the genital 

 armature this genus differs greatly from any of those allied to 

 Cistela, for in the male this part is not at all bilobed, and, what is 

 still more exceptional in the family, it is more strongly sinuate at 

 apex in the female than in the male; it is almost equally exposed 

 and prominent in both sexes. 



This genus differs from the European Cteniopus in having the 

 anterior coxse more widely separated, in the short third antenna! 

 joint, in its unextended front, and in the longer basal joint of the 

 hind tarsi. 



Andrimus will probably prove to be a moderately large genus in 

 our Grulf States, but the species are rather closely allied among 

 themselves, and may be difficult to discriminate from description, 

 especially as there is nearly always more plasticity and specific 

 variability in the genera with non-lobed tarsi, thau in the others. 

 The material which I have examined indicates five species, appa- 

 rently without much doubt ; these may be distinguished by the 

 following characters : — 



Basal angles of the prothorax prominent laterally murrayi 



Basal angles not prominent. 



Humeri very narrowly exposed at base l>rumieil$ 



Humeri widely exposed at base. 



Basal pronotal foveas almost obsolete COncolor 



Basal fovese small but deep and distinct. 



Eyes in the male separated by their own width nigrescens 



Eyes in the male separated by distinctly less than their own width.

A. murrayi Lee. — New Spec. Col., 1866, p. 141 (Cteniopus). — Oblong- 

 oval, shining and rather pale piceous-brown throughout ; pubescence rather 

 long, semi-erect and sparse on the elytra. Head nearly flat above, with a 

 transversely oval, deep impression involving the base of the epistoma and 

 margin of the front ; surface rather finely but deeply, somewhat densely punc- 

 tate, the punctures all distinct ; eyes separated by their own width, bordered 

 internally by a fine groove ; antennae scarcely one-half as long as the body, 

 slender, filiform, the third joint much more than twice as long as the second 

 and fully three-fourths as long as the fourth. Prothorax three-fifths wider 

 than long, rather campanulate in form, the basal angles right but distinctly 

 prominent laterally, the sides before them at first feebly sinuate then nearly 

 straight and parallel to anterior two-fifths, then strongly rounded to the apex 

 which is truncate and two-thirds as wide as the base, the latter transverse, 

 the sinuations rather narrow and feeble ; disk almost evenly convex, finely, 

 sparsely punctate, with a narrow impunctate median line ; basal foveas small
