The antehumeral (mesepisternal) and the mesepimeral stripes vary in colour in both 
sexes from metallic green to metallic brown or bronzy black, as has also been noted ® 
for this species in Lower (Baja) California. The width of the antehumeral stripe 
varies from one-half to one-fourth the width of the mesepisternum in the males, and 
from one-third to one-fifth, or occasionally one-seventh (a @ from San Gerdnimo), 
of the width of the mesepisternum in the females, the particular width not being 
correlated with locality. The mesepimeral stripe reaches almost to the base of the 
front wings in most of the material examined, but in some individuals (a ¢ from Rincon 
and a ¢ from Misantla, with the interalar dorsal surface pruinose, the 3 ¢ from 
Texas, and the single ¢ and 2 2 from San José del Cabo) it is much reduced in its 
extent upward ; these latter, therefore, approach A. californica, McL. The costa and 
median vein are blackish in all the present material that is not teneral. 
In no case does the nodal sector arise farther from the nodus than 12 cells; in some 
males from Cuernavaca and Guadalajara it begins at less than a cell beyond the nodus, 
in one wing at the nodal vein itself. 
The dimensions vary considerably :—Abdomen, ¢ 50 (Atoyac) —40 (Cape St. Lucas), 
@ 44 (Acaguizotla) -38 (Cape St. Lucas); hind wing, ¢ 88 (Atoyac, Cuernavaca) 
—29 (Cape St. Lucas), 2 39 (Acaguizotla)-32 (Cape St. Lucas) mm. Measurements 
made from a larger number of individuals from Lower California than are before
