The specimens labeled simply "Arizona" in the LeConte, Horn, and 

 United States National Museum collections probably all belong to the 

 original series of specimens of this species collected by H. K. Morrison 

 in the southern part of Arizona. In the Horn collection are three 

 specimens labeled "Texas," and unfortunately one of these females has 

 been designated as the lectotype by Chamberlin.

Figure 4. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (0) and of female (D) of Chrysobothris arizonica. 



Male. — Narrowly elongate, subcylindrical, moderately shining, bronzy brown, 

 with a distinct cupreous tinge ; beneath uniformly reddish cupreous, with a slight 

 purplish tinge. 



Head bronzy green in front, becoming cupreous on occiput, with a vague, smooth, 

 longitudinal carina on occiput ; front slightly convex ; surface coarsely, rather 

 densely, shallowly punctate, sparsely clothed with short, erect, inconspicuous 

 hairs, the intervals finely, densely granulose ; clypeus broadly, deeply, arcuately 

 emarginate in front, broadly rounded on each side. Antenna uniformly piceous, 

 with a faint bronzy-green tinge, gradually narrowed to apex; intermediate seg- 

 ments compact, wider than long, subtruncate at outer margins; third segment 

 subequal in length to the fourth. 



Pronotum three-fourths wider than long, slightly wider at apex than at base, 

 widest along apical half; sides nearly parallel from apical angles to behind 

 middle, then arcuately converging to posterior angles ; anterior margin slightly 

 sinuate, with a broadly rounded, median lobe ; base arcuately emarginate on 

 each side, the median lobe broadly rounded, and subtruncate in front of scutellum ; 

 disk strongly convex, without distinct callosities or depressions ; surface coarsely, 

 rather densely, shallowly, uniformly punctate, slightly rugose toward sides, 

 sparsely clothed with long, erect, inconspicuous hairs, the intervals densely, finely 

 granulose.
