DISTRIBUTION 



From material examined : 



Arizona: Tucson, August 12-14 (H. F. Wickhani). 



Texas: Laredo to Ringgold Barracks, 3 type (Scliott). Laredo, October 10, 1924. 

 Brownsville (H. F. Wickham and C. H. T. Townsend) ; March 23, 1908 (Jones 

 and Pratt) ; August 15, 1922 (T. C. Barber) ; May 1 (C. Schaeffer) : June 

 5, 1904 (H. S. Barber). 



Mexico: Fordale (M. M. Salozano). 



Chamberlin (1926) records the species from Yuma. Oracle, and Hot 

 Springs, Ariz.; Placer Count}', Death Valley, Calif.; and Mesilla 

 Valley, N. Mex., under atdbalipa Castelnau and Gory. 



Host. — Unknown. 



The color and sculpture on the dorsal surface of the body are con- 

 stant, but the foveae on the elytra vary in color from greenish yellow 

 to reddish yellow. The length is from 15 to 20 mm. 



LeConte (1857) applied the name atdbalipa Castelnau and Gory to 

 the specimens found abundantly in Texas, but in 1858 described them 

 as a new species under the name basalis. Saunders (1871) placed 

 basalis as a synonym of atdbalipa and LeConte (1873) states : "Chryso- 

 bothris basalis Lee. is atdbalipa C. & G. and Colobog aster multistigmosa 

 Mannerheim." 



TTaterhouse (1887) has basalis and atdbalipa confused under nudti- 

 stigmosa, in the treatment of which he says : 



The male appears to be dimorphic : numerous examples from various parts of 

 Mexico and one from Salvador have the antenna broad, compressed, and coppery, 

 with the third joint at its apex as broad as its length ; other specimens from the 

 same localities have the antennae comparatively narrow, with the third joint 

 elongate, scarcely widened at its apex. I have not seen an example of the form 

 with the broad antennae from the United States. 



Superficially the specimens of these species resemble one another 

 very closely but the male genitalia and third antennal segment are 

 quite distinct in the different forms and certainly represent valid 

 species. Watefhouse probably did not examine any males of basalis 

 from the United States. 



The type of basalis has been studied, and it agrees with all the speci- 

 mens examined from the United States and northern Mexico, and is 

 distinct from the other two species with which it has been confused.
