Host. — Adults were reared from larvae mining the bark and wood 

 of dying and dead stems of ocotillo (Fouquieria splendens Engel- 

 mann) collected in Arizona by G. Hofer. 



The color and sculpture of the dorsal surface of the body are 

 rather constant. The sides of the pronotum are either sinuate or 

 arcuately rounded at the middle, and the sides of the elytra are 

 usually parallel from the humeral angles to the apical third, but 

 occasionally specimens are found with the elytra widest behind the 

 middle. In some examples the prosternum is vaguely lobed in front, 

 but none could be considered as having it distinctly lobed. In the 

 females the apex of the last visible abdominal sternite is either 

 narrowly notched or rounded and serrate. The length is from 10.5 

 to 13 mm. 



Horn (1886) states that the prosternum is distinctly lobed in front, 

 but in the type the anterior margin is arcuately rounded in front, 

 although it cannot be considered as having a lobe. 



The species resembles schaefferi, but it is readily separated from that 

 species by the shape of the clypeus, which has a tooth on each side 

 of the median emargination, whereas in schaefjeri the sides are 

 arcuately rounded.
