and find that it m ust be associated with the marginatus group 

 by reason of the fourteen elytral striae as stated by Dr. Horn. 

 It is abundantly distinct from that species, or any of its al- 

 lies, however, in general form, and is distinguishable at once 

 from any other of the group by its black coloration ; it can in 

 no sense be considered a variety of marginatum. 



Tragosoma Serv. 

 Two species of this holarctic genus have previously (Col. 

 Xot.,11, p. 491) been made known by the writer, making, with 

 the two previously described, four well- characterized species. 

 Two more equally distinct are now added in the following 

 table, which includes also the European form for comparison : 



Elytral sculpture uniform throughout, the punctures coarse and 

 subconfluent; fine ridges distinctly traceable to the basal mar- 

 gin ; antennse glabi'ous 2 



El5^tral sculpture not uniform, the punctures distinct and widely 

 isolated throughout, becoming much coarser, deep and conspic- 

 uous toward base, where the tine subcostiform lines become ob- 

 solete in about basal third ; antenna) pubescent G 



2— Anterior tarsi rather strongly dilated in the male; prothorax 

 nearly twice as wide as the head and conspicuously hairy 3 



Antei'ior tarsi narrow and very feebly dilated in the male; prothorax 

 small, only slightly wider than the head, very broadly and 

 feebly rounded at the sides, with the process slender, abrupt 

 and spiculiform. V. n 



3— Sides of the prothorax acutely triangular between the apical and 

 basal angles, with the sides of the angle nearly straight and the 

 lateral process anguliform, broadening continuousljMrom its
