$ Macaria arenisca, Dognin, Ann. Soc. Ent. Belg., xl, 145 
(1896). 
$ Semiothisa inexcisa, Warren, Nov. Zool., iv, 480 (1897) 
(nov. syn.). 
IVIetan, Salta, in coll. Dognin. 
Very generally distributed in the Neotropical Region, 
from the West Indies and Colombia to nortliern Argentina. 
Dognin described from nine ^s from Ecuador, Warren from 
a $ from Trinidad. The two are certainly synonyms, 
though there may be some slight sexual differences. 
162. Macaria ramparia (Schaus). 
Semiothisa ramparia, Schaus, Tr. Amer. Ent. Soc., xxvii, 
168 (1901). 
Tucuman, in coll. Dognin. 
Schaus’ type was from S.E. Brazil, and I have not seen 
specimens from any other country, excepting M. Dognin’s. 
163. Macaria subclathrata (Warren). 
Semiothisa subclcdhrata, Warren, Nov. Zool., iv, 432 (1897). 
Tucuman, in coll. Dognin. 
Likewise described from S.E. Brazil. Known to me 
also from Paraguay and British Guiana. 
164. Tephrinopsis rectilineata (Warren).

Parana, Entre Rios (type and a series of both sexes), in 
coll. Rothschild ; Buenos Aires, fairly common, especially 
at light, from February to April (A. F. Bayne); San Juan, 
one December 21,1903, in coll. A. F. Bayne ; ? Tucuman 
and Los Vasquez, in coll. Dognin. 
Also occurs at Sapucay, Paraguay. 
A decidedly variable species in the strength of the lines, 
the presence or absence of a duplicating line or shade, 
wider or narrower, distally to the postmedian, etc. It is 
not impossible that the specimens which I refer to the 
following species really represent another form of this, 
in which case the range of variation is still wider.
