Gcometridac of the Argentine Republic. 341 
Iridopsis, which I noted as perhaps a form of the same 
species. 
250. Melanolophia apicalis (Warren). 
Cymatophora apicalis, Warren, Nov. Zool., vii, 195 (1900). 
Buenos Aires (H. Wilkinson), 2 1 ^ in coll. Br. Mus. 
Warren’s type was from S.E. Brazil; I know of uo 
further distribution. 
The Buenos Aires $ is larger and of a warmer, darker 
brown than the ^s. 
The name of Cymatophora (Hiibner, Tent., indescr.; 
Packard, nom. praeocc.—nec. Treitschke) is clearly unten¬ 
able for this group, which indues argilaria, Guen., coin- 
motaria, Mssn., and many others. On the other hand, it 
is certainly referable to Melanolophia, Hulst, Tr. Amer. 
Ent. Soc., xxiii, 357 ; the agreement of the South American 
representatives with canadaria, Guen., the type of that 
genus, is very close structurally, and even superficially. 
251. Melanolophia (?) granillosa (Dognin). 
Cymatophora (?) granillosa, Dognin, Ann. Soc. Ent. Belg., 
xlvi, 349 (1902). 
Tucuman, in coll. Dognin. 
Dognin’s type description does not give any definite clue 
as to the generic affinities. 
252. Melanolophia (?) eobusta (Warren). 
Cymatophora robusta, Warren, Nov. Zool., viii, 477 (1901). 
Parana, Entre Rios, type in coll. Rothschild. 
From the figure in the British Museum Collection (I 
cannot now compare the type), I do not think this can 
really be a Melanolophia. The shape, and the style of 
pattern, much rather suggest that it is related to usti- 
fnmosa, Warren, which I have provisionally placed with 
Stenalcidia. 
253. Melanolophia (?) gnamptographa (Prout), 
nov. sp. 
7. 38 aim. Head, body and legs brown, more or less tinged 
with reddish. Forewing reddish brown, irrorated with dark fuscous ; 
lines brighter brown, with a slight olivaceous tinge ; anteraedian ill- 
defined, from before one-fourth costa to before one-third inner
