Type.— Male, Cat. No. 21317, U.S.N.M.; Sierra de Guerrero, 

 Mexico, June, 1915 (R. Miiller). 



An old specimen in the Schaus collection from Jalapa, Mexico, is 

 labeled: '■^Bocchoris sp." in Hampson's writing; but I can not make 

 it fall in that genus. 



Genus BOCCHORIS Moore. 



BOCCHORIS CONTORTILINEALIS Hampson. 



Bocchoris contortilineaUs Hampson, Ann. Mag. Nat. Hist., ser. 6, vol. 16, 



p. 336. 

 Nacolcia verroniac Dyak, Ins. Ins., Menstr., vol. 5, 1917, p. 89. 



I make this synonymy on the close general resemblance of the two 

 forms. Hampson described contortilineaUs from Grenada; I have it 

 from Dominica, Jamaica and Cuba. N. var7'oniae I described from 

 British Guiana. The difference between Bocchoris and Nacoleia 

 Hampson gives as only " f rons fiat and oblique " in Bocchoris and 

 " frons rounded " in Nacoleia. Now, in contortilineaUs, the frons 

 may well be described as ." flat and oblique." The antennae set well 

 back and there is a distinct flattening before them. In N. verroniae, 

 however, there is no perceptible flattening, the frons is convex and 

 the antennae seem normally placed. A structural difference, there- 

 fore, exists between the continental and insular forms, but I cannot 

 consider it specific and, therefore, not generic. 



Genus SYNGAMIA Guenee. 



SYNGAMIA SUBNEBULOSALIS, new species. 



Fore wing gray-brown; inner line blackish, angled on median 

 vein ; discal mark a bar, oblique, a little bent ; outer line curved, from 

 costa to vein 2, black, white-edged without, preceded by white be- 

 tween the radial nervules, dislocated to a point under reniform and 

 continued obliquely to inner margin. Hind wing gray-brown; a 

 thick black line from end of cell obliquely to inner margin, followed 

 by white below vein 3; another outer bar from costa at outer third 

 to anal angle, followed by white from costa to vein 3; terminal line 

 black; fringe white, interlined with brown. Expanse, 16 mm. 



Type.— Female, Cat. No. 21318, U.S.N.M.; Cuernavaca, Mexico. 

 November, 1914 (R. Miiller). 



Genus LYGROPIA Lederer. 



LYGROPIA FALSALIS. new species. 



Fore wing pale subhyaline yellow ; costa purple brown ; a spot in 

 base of cell, orbicular and reniform, fused to costa, each with a 

 yellow center; outer margin broadly purple-brown at apex, narrow- 

 ing below, widening again abruptly at vein 2 to inner margin; a
