Anegcephalesis catheretes (Dyar), Ins. Insc. Menstr., vol. 7, p. 

 48, 1919 (food plant and altered spelling). — McDunnough, 

 Check list, No. 6176, 1939. — Bruner, Scaramuzza, and 

 Otero, Bull. 63, Estaoi6n Exp. Agron., Cuba, p. 69, 1945. 



Forewing brownish gray dusted with white; the 

 white shading more pronounced (on the males) in the 

 median area above the base of the cell, as a small spot 

 on inner margin below the dark markings on veins 2 

 to 5, and in outer area beyond the dark outer border of 

 the subterminal hne, on the female the white dusting 

 is more generally distributed over median and outer 

 areas and, on some specimens, on the basal area, giving 

 the wing an ashy gray appearance ; subbasal ridge black 

 bordered inwardly by a white line and followed by a 

 dull ohvaceous ocherous patch; antemedial line well 

 out towards middle of wing, obUque, notched at vein lb 

 and evenly curved above it, outwardly bordered by a 

 continuous black line; subterminal line distinct; in- 

 dented just below costa and very slightly so at lb; 

 discal spots fused into a lunate black line along dis- 

 cocellular vein; a dark brownish smudge over veins 1 

 to 5 adjacent to cell. Hind wings translucent white; 

 the veins very faintly darkened. A narrow brown line 

 along termen. Alar expanse, 20-23 mm. 



Male genitalia with uncus narrowly triangulate. 

 Apical process of gnathos a thin, broadly ovate plate. 

 Harpe with appressed, elongate clasper; sacculus not 

 produced at apex. Aedeagus sharply bent; penis armed 

 with an elongate, flattened, partially bent, platelike 

 cornutus, and some sclerotized wrinklings and granu- 

 lations. 



Female genitalia with signum developed as an elon- 

 gate, strongly spined plate (about half as long as bursa) ; 

 opposite the signum a narrower, much more weakly 

 sclerotized plate beginning at junction of bursa and 

 ductus bursae (this plate about half the length of 

 signum); bursa otherwise smooth; ductus bursae tubu- 

 lar, sclerotized. Eighth-segment collar fused ven- 

 trally. 



Type locality: Nassau, Bahamas (arctella, in Paris 

 Mus. ; cathaeretes, in USNM). 



Food plant: Dipholis salicijolia. 



Distribution: United States: Florida, Miami, 

 Paradise Key (Mar.), Koyal Palm State Park (Feb.). 

 Bahamas: Nassau (New Providence Isl., Feb., Mar., 

 April, May, Sept.). Cuba: Baracoa (Oct.), Santiago 

 Province (Feb., June, Sept., Oct., Dec). 



Ragonot's arctella was described from a single female. 

 His description and figure agree in every detail with 

 Dyar's cathaeretes represented by a large series in the 

 U. S. National Museum. Both were described from 

 the same type locality. There is no doubt that both 

 names apply to the same species. 



50. Magiriopsis, new genus 



Type of genus: Sematoneura denticosella Dyar. 



Characters of Zamagiria except: Antenna of male 

 unipectinate for basal half of shaft, serrate and shortly 

 ciliate beyond; shaft with very shallow sinus near base, 

 containing a few roughened scales and a short row of 

 minute spines but without scale tuft. Labial palpi of 

 male broad, dorsoventraUy flattened and appressed to 

 face (not to each other as in Zamagiria and Anegcephale- 

 sis); hoUowed umer surface; third segment greatly re- 

 duced and completely hidden by scaling of second 

 segment. Male head without scale tuft from upper 

 edge of frons, not deeply grooved between antennae but 

 with an enlarged scale tuft behind antennae. Maxillary 

 palpus of female squamous (of male, as in Zamagiria, 

 in the form of an aigrette). Forewing smooth; vein 2 

 from weU before outer angle of cell; 6 slightly bent 

 towards base but from below upper angle of cell, sepa- 

 rate from stalk of 8-9 at base. Hind wing with cell 

 less than one-third the length of wing. 



Male genitaha with complete transtilla.

Aigrette of male maxillary palpus whitish ocherous. 



Forewing reddish (rust) brown, the costal third lightly 

 dusted with white, especially along the costa and be- 

 tween the veins, the dark color somewhat accented on 

 the veins and, on occasional female specimens, some 

 black scaling on the veins before the usual location of 

 subterminal line; the latter rarely indicated; antemedial 

 line and discal spots obsolete. Hind wing translucent, 

 opalescent with a smoky shade at apex; a dark line along 

 termen and the outer veins faintly darkened. Alar 

 expanse, 32-40 mm. 



Male genitaha with uncus narrowly triangulate. 

 Apical process of gnathos a long, strong spine, sharply 

 hooked at apex. Transtilla a weakly sclerotized, shield- 

 like bridge attached to costal bases of harpes. Harpe 

 with costa strongly sclerotized for basal third of harpe 

 and terminating in a broad projection; sacculus with a 

 broad projection from base and a broadly projecting 

 clasper from apex. Aedeagus long and stout; penis 

 armed with three clusters of strong spines (about as 

 long as width of aedeagus). Vinculum elongate (two 

 and one-half times as long as greatest width), stout, not 

 appreciably tapering; posterior margin reinforced and 

 squarely excised. 



Female genitalia with two irregularly shaped and 

 strongly spined plates in bursa, and bursa at jimction 

 with ductus bursa strongly sclerotized, the wrinkled 

 sclerotization extending part way into the ductus; 

 ductus bursae otherwise only sclerotized (weakly) at
