Moderately robust, shining, dark blue, clothed with long, rather 

 sparse pubescence; fasciae of elytra red or yellow and variable in 

 extent, often greatly reduced. Head blue or green, moderately, not 

 very densely punctate. Thorax about equally as broad as long; 

 sides at apical fourth somewhat compressed, strongly compressed at 

 base; surface moderately coarsely, rather densely punctate. Elytra 

 blue ; a basal fascia, broad at the shoulders (the umbones blue) , extends 

 across base to near suture along which is it prolonged posteriorly, and 

 is generally dilated at its apex; a more or less oblique median fascia, 

 usually interrupted at the suture, is narrowly united at the flanks 

 with the basal fascia; an oblique fascia at apical fourth is likewise 

 frequently interrupted at the suture; surface feebly but rather 

 densely punctate. Body beneath, abdomen and legs blue; the tibiae 

 usually and the tarsi pale testaceous. Length 6.7-14.5 millim.

Var. tenellus LeConte. (Trichodes tenellus Lee., Proc. Acad. Nat. 

 Sci. Phila., 1858, p. 72; Horn, Ent. News, n, 1891, p. 6.) 

 This variety occurs in Colorado, New Mexico, and southern Cali- 

 fornia. It differs from the typical form in being more slender, the 

 elytra more coarsely, regularly punctured and the markings are also 

 slightly different, the median fascia being very oblique; the size 

 averages smaller, being 5.5-8 millimeters. This seems quite poorly 

 connected with the typical form, but as ornatus is known to be an 

 extremely variable species in color markings and size, the writer does 

 not feel warranted in placing tenellus as a valid species. Dr. Horn 

 (Ent. News, u, 1891, p. 6) gave a valuable contribution on the varia- 

 tion of the elytral markings in this species; in some examples the 

 elytra may be almost entirely red, while in others they may be blue 

 with a reddish spot at middle of their length, but this spot is never 

 contiguous to the lateral margin. 



This is a western species, while nuttalli is found in the eastern
