and find that it ni ust be associated with the mirglnatiis group 

 by reason of the fourteen elytral strias 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

Two species of this holarctic genus have previously (Col. 

 Not. ,11, p. 491) baan 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 

 subcontinent ; tine ridges distinctly traceable to the basal mar- 

 gin; antennae glabrous ......................... ................ 2 



Elytral sculpture not uniform, the punctures distinct and widely 

 isolated throughout, becoming much coarser, deep and conspic- 

 uous toward base, where the flue subcostitbrm lines become ob- 

 solete in about basal third ; antenna: pubescent ................ 



2 Anterior tarsi rather strongly dilated in the male; prothorax 



nearly twice as wide as the head and conspicuously hairy ...... : 



Anterior tarsi narrow and very feeblydilated in the male; prothorax 

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

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

 and spiculiform ................................................ ;> 



3 Sides of the prothorax acutely triangular between the apical and 



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

 lateral process anguliform, broadening continuously from its 

 apex. Northern United States and Canada ........ HARRISI Lcr- 



Sides of the prothorax broadly roundei, with the process spicu 15- 

 form and abruptly projecting from the arcuate limb ........... 4

 and very distinctly reflexed. Europe ........... DEPSARIA Linn- 



Elytra more than twice as long as wide, the lateral edges extremely 

 narrowly reflexed ; body brown in color, shining, the antennae 

 very slender and paler; prothorax strongly and closely, but

5 Pronotum rather finely punctate and conspicuously hairy, deeply 

 and transversely impressed throughout along the apical margin : 

 antennas relatively a little thicker than in the group with more 

 dilated tarsi; in general color, lustre and sculpture very similar 

 to sodalis, the body smaller. Length 24.8 mm ; width 8.0 m in
