similar in the two sexes ; shorter and broader in the male, very 

 narrow, cylindrical in the female. Eastern N. America. 



Eul^salis Lac. 



Antennae with outer four or five joints ovate or subovatc, last joint 



strongly anuminate. 



Thorax very sparsely and finely punctate, beak of male of the 



larger specimens very short and broad with prominent stout 



mandibles E. viinuta OHv. 



Thorax distinctly punctate, beak of large males elongate and 



narrower var. lecontei Pow. 



Antennas with outer five joints cylindrical or sub-cylindrical, last joint 

 long ; beak of male elongate narrow ; thorax very sparsely and 



finely punctate subsp. Sallei Pow. 



Outer joints of antennas broader 3 



3. Joints two to eleven gradually increasing in length and width 5 



Joints two to eight of antennae equal in width or very nearly so, last three 



joints slightly broader, forming a feeble club 4 



4. Suture between first and second ventral segments distinct and deeply 



impressed Vasseletia Sharp. 



Brown, opaque ; rostrum of male in front of antennal insertion mod- 

 erately broad and slightly dilated at apex, of female narrow and 

 cylindrical ; head and posterior part of rostrum impressed above ; 

 prothorax constricted in front, surface with longitudinal broad, 

 median impression ; elytral intervals alternately convex and not 

 punctate, the other intervals with large somewhat perforate punc- 

 tures. (Lower California) V. vasseleti Boh. 



Suture between first and second ventral segments obliterated at middle, 



visible at sides Trachelizus Schonh. 



Brown, more or less shining, rostrum nearly alike in the two sexes. 

 except that the basal part is as long as the apical in the male and 

 of equal width, while the female has the basal part shorter and 

 broader than the apical ; prothorax nearly impunctate with a strong, 

 longitudinal median impression ; elytra nearly parallel with strongly 

 impressed sutural strije which are impunctate, the other striae repre- 

 sented by rows of feebly impressed punctures, except the three near 

 side margin, which are deeply impressed. Femora and tibiae mutic. 

 (Key Largo and Elliott's Key, Florida.) T. ui'ciiuanus Boh. 



5. Head strongly constricted behind, vertex sulcata with basal angles slightly 



projecting backwards, behind each eye an angular projection.

Color piceous or castaneous ; prothorax elongate, oval, convex, not 



longitudinally impressed ; elytra with flavous spots nearly as in 



Enpsalis miiuifa and varieties. Rostrum nearly alike in both sexes,
