ASPIDIOTUS. 21. 
It is hardly possible that this is a native of Mexico, as it belongs to an Old-World 
group, and apparently comes close to Maskell’s A. dysoxyli. Prof. E. Henry (‘ Feuille 
des Jeunes Naturalistes,’ June 1898) has indicated an Aspidiotus fraxini from Europe 
but it proves that the name was based on a Mytilaspis.

Zool. & Ent. Iowa Agricultural College, no. 3 (1899), p. 23, figs. 5, 6. 
Hab. Mexico: Frontera (Townsend). Also a variety with lateral exuvie and a 
convex scale, Frontera, on ‘‘barenjeno chiquito,” June 9, 1897 (Townsend); for this 
Mr. Wilmon Newell has proposed the name parrottt. 
The variety could be taken for A. crawi, but it has not the circumgenital glands of 
that species. Also a variety with the scale a little smaller, more convex, lighter, with 
more lateral exuvie, Ometusco, April 29, 1898, on a malvaceous shrub or tree called 
“malvon,” with crimson flowers (Townsend). Also this species on “ chaya,” Jatropha, 
sp., Minatitlan, April 25, 1898 (Zownsend).
