A complete synonymy has been presented to indicate the incorrect 
author citations for this species. All the American lepidopterists 
have been in error in following Hampson’s citation of Boisduval as 
author of sabulosa. Boisduval gives a complete, accurate reference 
to the Felder plate and figure and credits the name to Felder. Hamp- 
son gave no reason for his use of Boisduval as author. It is possible 
that he did not consider the Felder treatment to constitute a descrip- 
tion. The original description by Felder consists of only a colored 
illustration of the moth and the name “A. sabulosa F.” Felder 
figured 25 moths on table 107 including 10 species assigned to Agarista. 
He used the complete generic name for the first species of the genus 
but used only the abbreviation ‘‘A.”’ for the remainder. 
This species is recorded in the literature from San Francisco, 
Calif. (Felder, Felder, and Rogenhofer, 1875), New Mexico (Hamp- 
son, 1901), Arizona (Neumoegen and Dyar, 1894), Mexico and Guate- 
mala (Druce, 1896) and Porto Rico (Méschler, 1890, noctuiformis). 
It is doubtful that this species occurs in the United States. The 
records from Arizona and New Mexico are undoubtedly referable to 
Gerra sevorsa (Grote). G. sevorsa (Grote) does occur in those States 
and was treated as a synonym of sabulosa by Neumoegen and Dyar 
(1894) and by Hampson (1901). Hampson (1920) corrected the 
erroneous synonym, but he did not change the recorded distribution 
for sabulosa. The type locality “San Francisco, California’ must 
certainly be an error. Twerta sabulosa (Felder) is known to occur in 
Mexico, Guatemala, El Salvador, and Porto Rico. Tuerta insulica 
Hampson from Trinidad is referred to the synonymy of sabulosa in 
the present paper so that locality may be added to the known distri- 
bution. Figures 22 and 23 illustrate the upper and lower surfaces of 
the wings of the type of insulica in the British Museum (Natural 
History). It is a battered example of sabulosa in which the white 
areas of the right forewing are aberrant. There is one specimen in 
the collection of the U.S. National Museum, via the Dognin collection, 
labeled “Paraguay, Pouillon.’”’ I do not know whether this locality 
record is authentic. 
There is considerable variation in amount and position of white 
coloration on the forewings of sabulosa. Draudt (1919) named two 
forms, albiplaga (a white spot present distad of reniform spot, median 
area otherwise dark gray) and albidisca (a white spot present distad 
of reniform spot, but median area around ordinary spots and to the
