NO. 2189. NEW FOSSIL BEETLES FROM FLORISSANT— WICKHAM. 465 



Legs in poor preservation, rather short. Length, from apex of man- 

 dibles to abdominal tip, 10.25 mm.; of elytron, 6 mm. 



Type.— Cat. No. 63443, U.S.N .M. 



Described from one specimen. Evidently this insect is not iden- 

 tical with any of those described by Scndder and it differs in protho- 

 racic outline from any of the Florissant fossil Carabidae with which it 

 might be compared. At first sight, it looks hke a Tenebrionid of the 

 UloTYia type, but the prothoracic hypomera are those of a Carabid. 

 The aspect, in this family, is decidedly harpaloid, whence the generic 

 reference which is to be given a broad interpretation. 



HARPALUS REDIvrVUS, new species. 



Plate 39, fig. 1. 



Form stout, similar to that of the recent H. ohlitus. Head short 

 and broad, rugose laterally beneath, the jaws not prominent. Anten- 

 nae obscure. Prothorax distorted but evidently rather short, pmic- 

 tured beneath at sides, prosternum nearly smooth. One elytron is 

 extended from the body and twisted so as to expose the upper sur- 

 face; this shows the striae to have been moderately deep with dis- 

 tinct transverse punctures closely placed, the interstitial spaces con- 

 vex, almost smooth. The other, overlapped by the abdomen, exhibits 

 only the general courses of the striae. Legs of moderate size. Length 

 of elytron, 10.85 mm.; of head and prothorax, 5 mm. 



Type.— Cfii. No. 63444, U.S.N.M. 



The single specimen indicates a species approached in the Floris- 

 sant fossil fauna only by Harpalus maceratus which is larger and has a 

 strongly projecting muzzle. It cannot possibly be confused with any 

 of Scudder's Carabidae. 



Genus ANATIS Mulsant. 



ANATIS RESURGENS, new species. 



Plate 38, fig. 1. 



Preserved hi ventral view. Antemiae wanting. Form subor- 

 bicular but with the edges, as preserved, interrupted at the j miction 

 of the prothorax and elytra. Head moderately large. Prothorax 

 subcrescentic in outline, the side margins not in good condition, the 

 base regularly arcuate, apex deeply emargmate, with a rounded lobe 

 at middle. Elytra, taken conjointly, of nearly circular outline appar- 

 ently with a wide side margin. On this margin are shown one or two 

 indistmct marks which appear to represent the similar creases in cor- 

 responding position on the underside of the elytra in the recent North 

 American Anatis 15-punctata. Length, 8 mm.; width, across elytra, 

 5.75 mm.
