p. 223, 1925; Proc. Ent. Soc. Washington, vol. 30, p. 135, 



1928. 



Male: Like that oi fernaldialis except that pectina- 

 tions of antenna are about half the length of those on 

 fernaldialis; transverse pale markings on forewing obso- 

 lete in some specimens. Alar expanse, 34-40 mm. 



Male genitalia similar to those oi fernaldialis except 

 smaller; harpe not so markedly creased. 



Female: Similar in color and markings to the female 

 oi fernaldialis. Alar expanse, 33-43 mm. 



Female genitalia with sclerotized ventral plate in 

 ductus bui'sae at genitalic opening larger and the oppos- 

 ing small plates on the dorsal wall of the ductus 

 narrower than those of fernaldialis. 



Type localities: Tres Marias Isl., Mexico (longi- 

 pennella, in BM); Orizaba, Mexico {elongalella, in 

 USNM). 



Food plant: Unlcnown, probably Ferocactus. 



Distribution: Mifixico: Orizaba, Oaxaca, Tehuacdn 

 (June), Cuernavaca (June, July), Zacualpdn (Mar., 

 Oct.). 



I have seen no examples from the type locality of 

 longipennella. 



541. Cactobrosis maculifera Dyar 

 Figures 525, 1051 



Cactobrosis maculifera Dvar, Proc. U. S. Nat. Mus., vol. 47, p. 

 407, 1914; Proc. Ent. Soc. Washington, vol. 30, p. 136, 

 1928.— Heinrich, Proc. U. S. Nat. Mus., vol. 86, p. 398, 1939. 



Male: Antenna strongly serrate and fasciculate. 

 Palpi, head, and thorax pale clay color ("luteous"). 

 Forewing luteous gray shaded and spotted with dark 

 grayish fuscous, the luteous tint pronounced on basal 

 third of costa and over the submedian area of the wing; 

 transverse antemedial and sub terminal lines obsolete; 

 a fuscous shade from costa before middle to cell, another 

 from costa at middle, and, below these, corresponding 

 streaks or spots on lower vein of cell and on vein lb; 

 a thin blackish line on the fold from its base to near its 

 middle; a similar dark streak on vein lb at outer thii'd; 

 short, broken, dark streaks on the veins at or near the 

 cell ; a clouded fuscous spot at end of cell ; outer half of 

 costa shaded with fuscous; a row of dark spots along 

 termen at or very close to the vein ends. Hind wing 

 white, semihyaline with only the faintest indication of

a fuscous line on termen toward apex. Alar expanse, 

 32-45 mm. 



Male genitalia agreeing in size and nearly all details 

 with those of longipennella except that the arms of the 

 anellus are a trifle longer in maculifera. 



Female: In color and pattern like the male except 

 that there is some gray shading on the head and thorax 

 and considerably more gray on the forewing (the single 

 specimen before me is in much better condition than 

 the males, which may account for some of the differ- 

 ences); basal third of wing clouded with dark fuscous; 

 terminal area more faintly clouded; subterminal line 

 faintly indicated, sharply angulate at middle, broken 

 below; the luteous shade more contrasted than in the 

 male, but restricted to middle of cell and the area be- 

 tween veins lb and the fold. Hind wing white, semi- 

 hyaline with a narrow fuscous shade along termen and 

 on the veins near their apices. Alar expanse, 37 mm. 



Female genitalia similar to those of insignatella but 

 with sclerotized ventral plate in ductus bursae at gen- 

 ital opening smaller. 



Type locality: Oaxaca, Mfeico (type in USNM). 



Food plant: Unknown. 



Distribution: Mexico: Oaxaca, Salina Cruz 

 (Sept.). 



This species may be distinguished from other species 

 of Cactobrosis by the strong luteous (pale clay) shade 

 on the forewing and the serrate-fasciculate male 

 antenna.

 1928.— Heinrich, Proc. U. S. Nat. Mus., vol. 86, p. 399, 1939. 



Male: Unknown. 



Female: Palpi, head, thorax, and forewing of a soft, 

 nearly uniform grayish fuscous (with a more brownish 

 than slate-gray tint) . Forewing wathout discal spot or 

 transverse dark markings; costa at base very slightly 

 paler than ground color of wing, concolorous with collar 

 of thorax; an obscure pale shade on midcosta and the 

 faintest indication of a pale subterminal line, the latter 

 broadly angulate at middle; some faint dark shading 

 on the veins from cell to termen and a row of small, 

 dark dots along termen near the vein ends. Hind wing 

 white, semihyaline, with a pale fuscous line along ter- 

 men; cilia white with a narrow, pale fuscous, subbasal 

 line. Alar expanse, 37-40 mm. 



Genitalia with the dorsal plates in ductus bursae at 

 genital opening strongly sclerotized; ventral plate at 

 opening slightly larger than in any of the other species. 



Type locality: Oaxaca, Mexico (type in USNM). 



Food plant: Unknown.

 the latter are more slate colored. The slight genitalic
