AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



55 



vein 3 ; a faint concentration of the black dusting on the 

 other veins. Hind wing semitransparent, more or less 

 smoky white ; darker on female than on male ; the veins 

 darkened, a broad dark shade along costa and a narrow 

 dark line along termen. Alar expanse, 22-24 mm. 



Male genitalia figured from type. On another male 

 in the British Museum from the type locality (June) the 

 stem of uncus is broader, the terminal part of vinculum 

 less constricted and its terminal margin less sharply 

 angled. (Another example of the amount of individual 

 variation that may be expected within specific limits in 

 this genus.) Female genitalia figured from specimen in 

 British Museum. The signum consists of thi-ee closely 

 grouped, moderately large, bluntly rounded disks. 



Type locality: Rio Negro, Amazonas, Brazil (May; 

 type in Paris Mus.). 



Food plant: UnknowTi. 



Known only from the type locality. A distinct 

 species easily identified by the contrasted black trans- 

 verse lines on the ash gi'ay forewing. 



105. PBeudocabima arizonensis, new species 

 Figure 698 



Similar in color and markings to the preceeding 

 species (nigristrigella) but darker, the black dusting 

 heavier (especially on basal area), giving the wing a 

 coarser, more pepper-and-salt appearance; no rust- 

 colored scahng between the veins; the antemedial and 

 subterminal lines blackish bordered on both sides but 

 the borders (especially of antemedial line) much less 

 contrasted than in nigristrigella; subterminal line acute- 

 ly angled at middle; somewhat expanded black streak- 

 ing on veins 2, 3, the stalk of 4, 5, and sometimes 6 for 

 a short distance from ceU; terminal dots fused into a 

 continuous black line along termen. Hind wing shining 

 white on male, pale smoky white on female; veins very 

 faintly darkened; a fine dark line along termen. Alar 

 expanse, 24-27 mm. 



Male genitalia exhibiting no specific characters. 

 Female genitalia with signum a compact cluster of 

 numerous, closely appressed disks. 



Type locality: Redington, Ariz, (type in USNM, 

 61324; paratypes in Paris Mus., Cornell Univ., Trans- 

 vaal Mus. (Janse Coll.), and BM). 



Food plant: Unknown. 



Described from male type and 2 male and 6 female 

 paratypes from the type locality; 8 male and 11 female 

 paratypes from the Baboquivari Mts., Ariz. (June, 

 July, Aug., Sept.) ; and 4 male and 1 female paratypes 

 from Mohave County, Ariz. (Aug., Sept.). 



So far, this is the only species of the genus recovered 

 from the United States. In general habitus it resembles 

 Euzophera nigricantella Ragonot, also from Arizona. 



106. Pseudocabima expunctrix (Dyar and Heinrich), new combina- 

 tion 



Figures 224, 692 



Myelois expunctrix Dyar and Heinrich, Proo. Ent. Soc. Washing- 

 ton, vol. 31, p. 116, 1929. 



Forewing slate gray; some black scaling on the veins 

 and (under magnification) a faint scattering of white 

 scales over outer area; antemedial and subterminal 

 lines and discal spots lacking; a row of black dots at 

 the vein ends along termen. Hind wing semitrans- 

 lucent white, a smoky shade at apex, along costa, and 

 on the veins (especially of the female, the veins of the 

 male wing not appreciably darkened) ; a fine dark line 

 along termen. Alar expanse, 22-30 mm. 



Female genitalia with signum a long chain of pointed, 

 thornlike disks. 



Type locality: Baia, Brazil (type in USNM). 



Food plant: "Stems of leguminous tree." 



Known only from the type series. The only reared 

 species of the genus and the only one without any 

 trace of transverse marldngs. One of the male para- 

 types proves to be a specimen of Fundella argentina 

 Dyar. In the forewing veins 4 and 5 are somewhat 

 longer stalked than in other species of the genus except 

 perrensiella, the stalking being for a half to slightly 

 more than half their lengths. 



107. Pseudocabima perrensiella (Ragonot), new combination 

 Figure 695 



Myelois perrensiella Ragonot, Nouv. Gen., p. 8, 1888; Mono- 

 graph, pt. 1, p. 52, 1893. 



From Ragonot's description and figure the species 

 must be similar to expunctrix except for the presence 

 of a distinct pale subterminal line, a trace of an ante- 

 medial line, and a thin dark line along discocellular vein. 

 Veins 4-5 are "long-stalked," as in expunctrix. Alar 

 expanse, 28 mm. 



The female genitalia differ from those of all other 

 described species of the genus in having a sharp, par- 

 tially sclerotized, deeply wrinkled, and densely scobi- 

 nate bend in ductus bursae near its junction with bursa 

 copidatrix; the signum consists of a curved band of 

 bluntly rounded, closely impacted, thornlike disks. 



Type locality: Goya, Argentina (type in Paris 

 Mus.). 



Food plant: Unknown. 



Known only from the female type. 



108. Pseudocabima rubrizonalis (Ilainpson), new combination 

 Figures 225, 694 



Crocidomera rubrizonalis Hampson, Ann. Mag. Nat. Hist., ser. 

 10, vol. 4, 353, 1929. 



Forewing pale gray; the costal edge and the veins 

 beyond cell purplish brown; the basal area suffused 

 with some faint dark dusting on the male, considerably 

 darker on the female; antemedial line at middle of wing, 

 vertical or nearly so, dull white, bordered on inner and 

 outer sides by reddish brown bands, the outer one the 

 wider and somewhat broadened in cell; subterminal 

 line faint, when distinguishable, grayish white, set well 

 back from outer margin (the space between it and 

 antemedial line correspondingly reduced), sharply out- 

 angled, the apex of the angle in the fork of veins 4-5; a 

 black line, slightly curved, along discocellular vein;
