568 SUPPLEMENT. 
1. Amaropsis annulicornis. (Tab. XXIII. fig. 18, 2.) 
9. Aineous, very shining, the head in front, the oral organs, and legs ferruginous. Head closely, finely 
punctate, shallowly, transversely grooved in front ; antenne with joints 1 and 2 entirely and the tip of 
each of the following ones rufo-testaceous, for the rest piceous ; prothorax transverse, very much wider 
at the base than at the apex, the sides rounded and rapidly converging from the middle, parallel behind, 
the hind angles subrectangular, the basal fovez oblique, distinct, the surface sparsely, finely punctate ; 
elytra with regular rows of very fine, oblong, approximate punctures placed upon almost obsolete striz, 
the punctures becoming a little coarser towards the base and still finer towards the apex, the interstices 
perfectly flat throughout, each with a single row of exceedingly minute, distantly placed punctures (only 
visible under a strong lens); beneath very shining, sparsely, finely punctate, the venter very finely so. 
Length 5, breadth 27 millim. 
Hab. Mexico, Misantla (Flohr). 
One example. 
PHEDIUS (p. 447). 
Some of the species of Phedius (P. cylindricollis &c.) have rudimentary wings, but 
they are not easily seen unless the elytra are removed. In my definition of the genus 
the body is stated to be apterous. The mandibles in P. lapidicola are deeply cleft, 
the upper tooth longer than the lower one. All the species appear to be rare, very few 
examples of any of them having been received as yet. According to Mr. Flohr, they 
are found beneath stones. 
1 (a). Phedius lapidicola. 
Oblong-obovate, convex, pitchy-brown, the elytra shining, the head and prothorax duller, the entire upper 
surface thickly clothed with long erect bairs. Head densely, somewhat coarsely punctured, very deeply 
transversely grooved in front ; mandibles deeply cleft; antenne ferruginous, very stout, filiform, nearly 
reaching to the middle of the elytra, joint 3 considerably longer than 4; prothorax scarcely wider at the 
base than at the apex, very convex, transverse, widest at one-third from the apex, the sides strongly 
rounded anteriorly and gradually converging behind, the base truncate, the hind angles obtusely rect- 
angular, the entire surface very densely, somewhat coarsely punctured ; elytra oblong-oval, much wider 
than the prothorax, widest beyond the middle, with rows of moderately fine, subapproximate punctures 
placed upon almost obsolete strie, the interstices flat, thickly, confusedly punctured, the punctures of the 
strie not coarser than (and scarcely distinguishable from) those of the interstices and becoming finer at 
the apex; beneath ferruginous, shining, thickly and rather coarsely punctured, clothed with long, decum- 
bent hairs ; legs very stout, obscure ferruginous ; body apparently apterous. 
Length 83, breadth 32 millim. 
Hab. Mexico, Sierra above Cuernavaca (Flohr). 
One specimen. Allied to P. chevrolati (of which additional Mexican specimens have 
been received from Mr. Flohr), but with the head and thorax less rugose, the elytra 
shining and sculptured as in P. cylindricollis and P. obovatus. 
1 (8). Phedius hirtus. (Tab. XXIII. fig. 26, ¢.) 
Obovate, rather broad, convex, piceous, the elytra shining, the head and prothorax duller, the entire upper 
surface thickly clothed with long, semierect hairs. Head very densely, finely punctate, deeply transversely 
grooved in front ; mandibles feebly cleft ; antenne fusco-ferruginous, filiform, slender, reaching to about
