A. cubitalis Navas; venation generally similar to that 
species, two or three cross-veins in hind wings before radial 
sector, three in fore wings, about five branches to radial 
sector. The hind wing is so slender that the branches of 
cubitus are nearly simple, only a few forked and no cross- 
veins between them as in A. cubitalis; the marginal hair is 
shorter than in cubitalis. Fore wing, length 16-18 mm., 
width 3.5-4 mm. Hind wing, length 15-17 mm., width 2.5-3 
mm. Abdomen 16-18 mm. long. 
From S. Barbara, 15 March, and N. Gerona, 1 March, 
Isle of Pines, Cuba, both by C. S. Bruner. 
Differs from cubitalis Navas not only in smaller size, 
more slender wing, but also in pronotal marks, cubitalis 
having a single median mark behind; the spots on vertex 
also different. Both specimens lack the spots along cubitus 
seen in cubitalis.
