] 4 PROCEEDINGS OF THE NATIONAL, MUSEUM vol. 79 



Palpus ocherous blotched on outer side with fuscous. Basal joint 

 of antenna fuscous. Face and head tawny-ocherous. Thorax and 

 fore wing pale tawny-ocherous peppered with blackish scales, the 

 latter arranged in transverse lines on fore wing and but faintly 

 visible to the naked eye, most conspicuous as a dark shading at end 

 of cell; cilia pale ocherous-ferruginous. Hind wing but slightly 

 darker than fore wing, a trifle more fuscous. 



Male genitalia as in nivelguttana Grote, except that cucullus of 

 harpe is somewhat more slender. 



Alar expanse. — 18 to 19 mm. 



Type and paratj/pes.— U.S. 'NM. No. 43260. 



Type locality. — St. Petersburg, Fla. 



Food plant. — Unknown. 



Remarks. — Described from male type and two male paratypes from 

 the type locality ("3-3-15," R. Ludwig). 



A distinct and easily recognized species. It lacks altogether the 

 strong pattern markings and white cell dot of the other two species 

 of the genus and has the hind tibia even less tufted than that of 

 nivelguttana. Its genitalia, however, are distinctly of Phaecasio- 

 pliora type and scarcely distinguishable from those of niveiguttana. 



TSINILLA, new genus 



Plate 5, Figure 17 



Genotype. — Ewcostna lineana Fernald (North America). 



Description. — Thorax with posterior tuft. 



Fore wing smooth; termen concave; 12 veins, all separate; T to 

 termen; 8 and 9 approximate at base; upper internal vein of cell 

 from between 9 and 10; 3, 4, and 5 not approximate at termen; 2 

 strongly bent and running up to termen parallel to 3; Ic indicated 

 by a distinct fold in the wing in both sexes, the fold running into 

 vein 2. 



Hind wing with 8 veins ; 6 and 7 approximate toward base ; 3 and 

 4 connate; 5 approximate to 4; termen slightly sinuate below apex; 

 in male a chitinous ridge on inner margin. 



Hind tibia of male with hair pencil from base. 



Male genitalia with harpe narrowly elongate, rather evenly spined 

 from sacculus to apex; cucullus small, less than half the length of 

 the harpe; cornuti a cluster of long deciduous spines; uncus weakly 

 spined. 



Female with two thornlike signa in bursa; ductus bursae moder- 

 ately long, strongly chitinized toward genital opening. 



A monotypical tropical genus extending into southern Florida. 

 Shows affinities to Eunmrozia, Zomaria, and Hedia.
