34 TERTIARY COLEOPTERA OF NORTH AMERICA. 



NoTHOPUs KiNGii sp. nov 

 PI. IV. fig. 2. 



A single fractured specimen represents a species somewhat larger than 

 the living American form, but which agrees with it in all essential points. 

 Of the head only a fragment remains. The prothorax is broad and short, 

 being fully twice as broad as long, with rounded sides, sharp angles, barely 

 perceptible impressed median line and a smooth surface, with some slight 

 corrugations next the posterior border. The elytral striaj are in all respects 

 similar to those of iV^. zahroides LeC. without punctures, and the interspaces 

 are very gently convex, almost flat, and, so far as can be seen, without 

 punctures. The humeral stria, not shown in the plate, is closely approxi- 

 mated to the first stria, and is shorter than in N. mhroides. The scutellum 

 is larger than in the living species and sparsely covered at base with short 

 hairs. The specimen shows an obverse in which the striae appear as ridges. 



Length of specimen, 16 mm.; of elytra, 11 mm.; breadth of elytron, 

 4 nun. 



Florissant, Colorado; one specimen. No. 5984. 



Named for Clarence King, first Director of tlie United States Greological 

 Survey. 



HARPALUS Latreille. 



Of this dominant cosmopolitan genus, of which nearly fifty species are 

 now found in North America, fourteen species have been found in the earlier 

 Tertiaries of Colorado in the New World and, in the Old, at Oeningen, Aix, 

 Radoboj, Rott, and Brunstatt in Alsatia, besides being recognized in amber. 

 Two extinct species are also known from the Pleistocene of Switzerland and 

 Galicia, besides one from the Pliocene of England; a single existing species 

 is also recognized in the Swiss Pleistocene. 



Harpalus nupeeus sp. nov. 



PL III, fig. 6. 



A species is indicated near H. nitidulus Chaud., but it is rather obscure. 

 The head is a little longer only than broad, at base with very straight and 

 parallel sides. The prothorax is a third as broad agam as the head, and 

 nearly twice as broad as long, with well-rounded sides and especially with
