THE NORTH AMERICAN SPECIES OF PEDILOPHORUS. 



BY H. F. WICKHAM, IOWA CITY, IOWA. 



The Byrrhidte of this continent have received a comparatively small 

 share of attention at the hands of systematists for many years, so that it is 

 not at all surprising to find novelties among recently-collected material. 

 Two new forms of the genus Pedilophorus have recently been detected 

 among the accumulations in my cabinet, i^oth of them from the west ; no 

 doubt still others remain to reward explorers of the mountain ranges and 

 of the northern districts. The European fauna contains ten species, while 

 but four were previously known from North America. For the sake of 

 better understanding of the new forms, I have constructed the following 

 table, by means of which our native species may be identified : 

 A. Elytral punctuation disposed in broad vittie, alternating with nearly 



smooth stripes. .34 inch Lecontei, n. sp. 



AA. Elytral punctuation not disposed in vittae. 



b. Tarsi simple. A green-bronzed species, clothed with coarse 

 whitish hairs. . 1 7 inch ceneoluSy Lee.
