T. ELEGANS Er. {occidentalis Gorh.) Brownsville, Texas, June; Mesilla,, 

 New Mexico, August 12. My two specimens are quite different in appear- 

 ance, the one from Brownsville being uniformly dark above excepting the 

 humeral spot and transverse band, while the Mesilla example is black only 

 behind the band, the whole upper surface anterior thereto being testaceous 

 with the exception of the spots and the band which are light colored as in 

 the other and of a similar eburneous gloss. The insect occurs as well in 

 Arizona, Lower California, Mexico, Guatemala, Nicaragua and Peru. 



Cymatodera Gray. 



The species of this genus are comparatively rare and are ordinarily taken 

 by beating trees or bushes of various kinds, seldom occurring on flowers 

 though occasionally resting under bark. It is unusual to take more than 

 one or two examples from a single plant. They are strongly attracted by 

 lights and may be found in the mornings about the doors of buildings 

 where they have crawled in after having been drawn by the illumination. 

 •Partially dead branches yield them more freely than healthy vegetation. 

 The genus is well represented in the arid districts of our southwest.

 bution extends from Western Texas through New Mexico to California and 

 down the Peninsula.
