the areole is simple. Mr. Warren, on his favourite char¬ 
acter of the ^ antenna, recognises at least four genera— 
Cyllopoda, Dahn., Atyria (Hiib.) H.-S., Atyriodes, Warr., 
and Paratyria, Warr. 
44. Atyria semidivisa (Warren). 
? Xanthyris basina, Boisduval, Lep. Gnat., 93 (1870).^ 
Cyllopoda semidivisa, Warren, Nov. Zool., iv, 420 (1897).^ 
Flavinia Druce, Ann. Mag. Nat.'Hist., (7) iii, 296 
(1899) (nov. syn.).^ 
Cyllopoda chihcha, ah. mTiet/cra, Warr., Nov. Zool., xi, 15 
(1904) (nov. syn.).^ 
(2) Parana, Entre Rios (types), in coll. Rothschild. 
Also recorded from Bolivia (^) and Paraguay (‘^). The 
British Museum has examples from the latter locality. 
Mr. Warren (in litt.) tells me he considers it to be the 
same as Boisduval’s Xanthyris basina (^) from Guatemala 
and Venezuela; but I suspect, on geographical grounds, 
that the two may be rather close allies than synonyms. 
Even at Santa Catharina, according to Boisduval, basioia 
is replaced by another species (castina, Boisd., nom. nud.). 
45. Atyria durnfordi (Druce). 
Flavinia durnfordi, Druce, Ann. Mag. Nat. Hist., (7) iii, 
296 (1899). 
Buenos Aires (taken by Durnford), in coll. H. Druce. 
Also occurs in Paraguay. 
46. Atyria isis (Hiibner). 
Atyria isis, Hiibner, Zutr., ii, 31, fig. 385-6 (1823).^ 
Fla.vinia dubia, Schaus, Proc. Zool. Soc., 286 (1892) (nov. 
syn.).2 
The northern provinces of Argentina, according to 
Burmeister, Descr. Phys. Arg. Rep., v (1), 420. 
Distribution: Brazil (^) (^); Paraguay (Burmeister, loe. 
cit.). 
Note. —Burmeister (/or. cf^.) also records Atyria osiris. 
Cram.,” from the northern provinces and Parana, Entre 
Rios. I am quite unable to say what species he had 
before him. The true osiris, Cram. {Cyllopoda), is only 
known to me from the Guianas, and the species which is 
often confounded with it, Cyllopoda jatropharia (Linn.),
