fine, separated by a distance at least twice their own diameters, inter- 

 spaces flat and obsoletely, minutely reticulate. Abdomen rather densely 

 punctulate and clothed rather densely, especially at the sides and on the 

 fifth segment, with moderately long, recumbent, luteo-cinerous hairs.

 ft. Beaten from the flowers of Querctis echinoides var. densi- 

 flora in July. 



The specimens before me are apparently all females, the 

 apical margin of the fifth ventral segment is feebly arcuate, 

 and the third joint of the antennae slender. 



This species differs from vicinus in its much finer punctua- 

 tion ; from hudsonicus it is recognized by the broadly rounded 

 basal angles of the prothorax. The pubescence is noticeably 

 shorter than in vicinus y and less bristling and lighter in color 

 than in hudsonicus, the prothoracic proportions are quite dif- 

 ferent in the two species. Obtusus occurs in Colorado and has 

 the elytra finely, sparsely and but slightly rugosely punctate. 

 Expansus which occurs north of San Francisco is more de- 

 pressed in form. 



Casey's synoptic table may be modified as follows for the 

 reception of the above species : 



Pubescence distinctly intermingled with longer erect black hairs. 



Elytral vestiture blackish throughout ; thoracic sculpture rather 

 dense hudsonicus. 



Elytral vestiture luteo-cinerous throughout except the longer erect, 

 black hairs ; thoracic punctures coarse and impressed.. vicinus. 

 Thoracic punctures fine not impressed. Basal angles broadly 

 rounded shastensis. 



Elytral vestiture cinerous, except the longer erect black hairs ; basal 

 angles obtuse and slightly blunt ; thoracic punctures sparse. 



obtusus. 



Elytral vestiture cinerous but becoming dark and inconspicuous be- 

 hind the middle ; elytra broad and depressed . . . expansus.
