RUPELA SEGREGA, new species 



Plate 23, Figures 6-6d : Plate 30, Figure 32 



Male. — Wings shining white. Fore wing with veins 11 and 12 

 separate; 4 and 5 approximate or connate. Hind wing with 4 and 

 5 connate or stalked. Anal tuft white. 



Alar expanse, 26-33 mm. 



Genitalia with gnathos beaklike but with lateral arms (attaching 

 to tegumen) developed; posterior margin of central basal part 

 rounded; inner surface finely scobinate; apex upturned. Uncus with 

 basal part slightly humped, stout, subquadrate, deeply excavate 

 posteriorly and dorsally; apical two-thirds digitate, laterally com- 

 pressed on dorsum at apex (as in leucatea and 'pallidula). Harpe 

 simple; cucullus but slightly narrowed; basal process of costa mod- 

 erately^ produced, fusing with a very weakly sclerotized transtilla; 

 sacculus not i)roduced at apex. Anellus consisting of ventral plate 

 and a somewhat roughened dorsal piece, tlie latter bearing one pair 

 of long, stout spines and two pairs of shorter spines; ventral plate 

 with upper margin incised, lateral margins deeply incised, Aedea- 

 gus Avith a})ex cleft, l:iterally expanded and spined on lateral 

 margins. 



Female. — "Wing color and venation as in the male. Anal tuft 

 white. 



Alar expanse, 28-38 mm. 



Genitalia with genital plate Avell defined and somewhat similar 

 to that of aJlmieUa but with caudal margin more acutely angled; 

 genital opening almost as wide as plate, the lower (outer) margin 

 concave; ductus bursae strongly sclerotized (and brown) for a short 

 distance from genital opening. 



Type and paratypes. — U.S.N.M. no. 51859. Paratypes also in 

 British Museum. 



Tyj)e locality. — South Bay, Lake Okeechobee, Fla. 



Remarks. — Described from male type, eight male and five female 

 paratypes, the paratypes distributed as follows : Florida, Glenwood, 

 one male, Fort Meade (April), two males and one female, Coconut 

 Grove (E. A. Schwarz), two males, Koyal Palm State Park (F. M. 

 Jones, March), one male (W. S. Blatchley, April) and one female. 

 South Bay, one female, Dade City (September), one male, Biscayne 

 Bay, one female; North Carolina, Havelock on Lake Ellis (F. Sher- 

 man, June), one female; also one male without any locality label. 



A North American species apparently confined to the southern 

 part of the United States. Specimens of segrega (as well as sejrmcta 

 and white Florida females of tincteUa) have hitherto been identified 

 as alhlnella Cramer. The latter as far as I know does not occur 

 in the United States.
