separated by more or less than their own long diameters. Interstitial 

 spaces flat, broad, pubescent but scarcely visibly punctulate. Only 

 one leg shows, which is of moderate size. - Length of fragment, 13.40 

 mm.; of prothorax, along median line, 3.50 mm. 



Described from one specimen. 



Type. — In the Museum of the University of Colorado. It was 

 collected at Station 14, Florissant, Colo., by S, A. Rohwer. 



Placed in Athous because of the form, the coxal plates (only in- 

 distinctly seen), the frontal margin and the very long prosternal lobe 

 which shows through as indicated, Plate 6, fig. 5. In this figure, the 

 dotted lines will show the courses of the elytral striae, but the punc- 

 tures are actually somewhat smaller and more numerous than the dots 

 which might be taken to represent them. It seems smoother than 

 the recent North American species known to me. 



Paranomus exanbl^tus, sp. nov. 

 Plate 6, fig. 6, 7. 



Form only moderately elongate. Head practically smooth. An- 

 tennae not well enough preserved to show the relative sizes of most 

 of the joints, but they are quite weakly or scarcely serrate, reaching, 

 in life, beyond the prothoracic hind angles. Prothorax in poor 

 condition and probably somewhat distorted, but as shown it is a little 

 more than one fifth broader than long, wider in front of the middle, 

 front angles a little acute, sides moderately arcuate in anterior three 

 fourths, thence sinuate, in reverse curve, to the hind angles which 

 are sharp and slightly divergent, base broadly emarginate in front 

 of the scutellum, sinuate each side, surface minutely, sparsely punc- 

 tured. Scutellum suborbicular. Elytra three times the length of the 

 prothoracic median line, conjointly rounded apically, not striate nor 

 visibly punctured but finely pubescent. Underside nearly smooth. 

 Length, 7.00 mm. ; of elytron, 4.30 mm. 



Described from one specimen, with counterpart. 



Type. — In the collection of H. F. Wickham. Wilson Ranch, 

 Florissant, Colo. With it is associated, somewhat doubtfully, an- 

 other from the same source. 



Most probably a Paranomus, but more finely sculptured than P. 

 costalis or P. estriatus, the only recent species know to me. 

 The prosternal sutures are moderately curved, the hind coxal
