TRICHODES ORNATUS Say.

In consequence of some correspondence lately had in refer- 

 ence to this insect and the apparent incredulity that two forms 

 seen, which differ less than any two figures on the subjoined il- 

 lustration, were merely varietal differences, I have thought it 

 desirable to select a few forms illustrative of variation in two 

 directions from the typical form. 



The thorax varies in color from blue to green, through brassy 

 and cupreous. The elytra are usually deep blue or blue-black, but 

 may be bright blue or green. The pale bands are of a Cicindeloid 

 type, and may be bright yellow or orange-yellow. The legs are 

 blue, the anterior four tarsi pale, but those specimens with the 

 wider bands of yellow often have pale tibiae also. 



On the accompanying illustration are five specimens selected 

 from my series showing the extent of variation in the markings. 

 The central figure is the common form in the region from which 

 Say obtained his specimens, near the base of the Rocky Moun- 

 tains. The humeral and the median band are often united along 

 the outer side. Fig. 2 represents a form quite usual in Owen's 

 Valley, Cal., and western Nevada, the yellow being quite equal 

 to the blue color. Fig. 3 shows a form from Utah in which the
