CARABID.E. 35 



well rounded posterior angles and no sign of any median impressed line. 

 The elytra are somewhat bi-oader than the thorax, rather slender, with nearly 

 parallel sides on the basal half, the humeral angle a little rounded, and on 

 the apical half tapering rather rapidly. As the under surface is exposed, 

 the strise are not shown. 



Length of body, 7 mm.; of elytra, 4 mm.; breadth of lioth elytra, 

 2.75 mm. 



Florissant, Colorado; one specimen. No. 166. 



Harpalus whitfieldii sp. uov. 

 PL IV, tig. r. 



A rather stout species not far removed from H. elli])sis LeC, with the 

 prothorax nearly twice as broad as long, half as broad again as the head, 

 the sides well rounded, a distinct median inapressed line, and the surface 

 slightly rugose posteriorly. The elytra are considerably broader than the 

 thorax, broadest in the middle and considerably narrowed anteriorly as well 

 as posteriorly, the humeral angle being roundly excised, and the opposite 

 sides nowhere parallel; the strite are delicate without punctures, and the 

 interspaces scarcely convex with faint signs of scattered shallow punctures. 



Length of body, 7.5 mm.; breadth of thorax, 2.7 mm.; of elytra, 3.6 mm. 



Florissant, Colorado; thi-ee specimens. No. 10104, and from the museum 

 of Princeton College Nos. 1.574, 1.829. 



Named for the New York jjaleontologist, R. P. Whitfield. 



STENOLOPHUS Dejean. 



Of this widespread genus, tolerably rich in species, of which about 

 a dozen are known in North America, but a single fossil species is known, 

 from Colorado. 



Stenolophus religatus sp. nov. 

 PL IV, fig. 1. 



A rather obscure specimen which appears to be allied to 8. ochrojyeziis 

 Say. The head is large, longer than broad, with straight sides tapermg- 

 anteriorly. The antennae are moderately stout, a little longer than the 

 head and thorax, the joints about twice as long as broad. The prothorax 

 is scarcely broader than the liead, about twice as broad as long, with
