area brownish ocherous, shading to brown at extreme 

 base and with a clouding of white in midbasal area ; ante- 

 medial line complete, weU out on wing, oblique, inwardly 

 notched at vein lb, white, bordered outwardly by a 

 narrow blackish line; subterminal line also complete, 

 further back from termen than in the two preceding 

 species, oblique (parallel to termen), whitish ocherous 

 with a narrow blackish inner border; discal dots distinct, 

 separated, black. Hind wing dark brown; the fringe 

 whitish ocherous with a dark median band. Alar ex- 

 panse, 24 mm. 



Male genitalia similar to those of scobiella except: 

 Uncus narrower and tapering to more narrowly rounded 

 terminal margin; vinculum longer in proportion to its 

 width; spines on aedeagus fewer and coarser. 



Type locality: "VUla Anna, F. S. C. Fe., Argentina" 

 (type in BM). 



Food plant: Unknown. 



Described from imique male, collected by K. J.

76. Genus Pyla Grote 



Pyla Grote, New check list of North American moths, p. 55, 

 1882. — Ragonot, N. Amer. Phycitidae, p. 9, 1887; Mono- 

 graph, pt. 1, p. 481, 1893. — Hulst, Phycitidae of N. Amer., 

 p. 161,1890. (Type of genua: Nephopieryx scintillans Giote.) 



Tongue well developed. Antenna finely pubescent; 

 on male with sinus and scale tuft in base of shaft. 

 Labial palpus oblique; second segment broadly scaled, 

 somewhat flattened laterally, reaching above vertex; on 

 male with a slight groove to hold the maxillary palpus; 

 third segment short, less than one-third the length of 

 second, porrect. MaxiUary palpus of male in the form 

 of an aigrette, semiaigrette (i. e., the scales hairlike 

 but short), or more or less squamous. Forewing smooth; 

 11 veins; vein 2 from near lower outer angle of ceU; 3 

 from the angle, slightly nearer to 4 at base than to 2 ; 

 4 and 5 slightly separated at base, parallel for a short 

 distance beyond ceU; 6 from below upper angle of cell 

 straight; 8 and 9 stalked from one-half to a third of 

 their lengths; 10 from the cell, slightly separated at 

 base from the stalk of 8-9; male without costal fold. 

 Hind wing with vein 2 from before but rather near 

 lower outer angle of cell; 3 from the angle, connate with 

 4; 4 and 5 stalked or anastomosed for half or slightly 

 less than half of their lengths; 7 and 8 contiguous or 

 very weakly anastomosed for a short distance beyond 

 cell; cell less than half the length of wing; discocellular 

 vein curved, outwardly produced at lower angle and 

 connected with vein 3 by a short spur. Eighth abdom- 

 inal segment of male with a pair of ventrolateral hair 

 tufts (fig. 372b), or two or three pairs containing some 

 modified scales (fig. 367c). 



Male genitalia with uncus broad, more or less trian- 

 gulate. Apical process of gnathos a short, stout hook. 

 Transtilla absent. Harpe usually with base of costa 

 produced into a strong projecting hook, or spine, or 

 spined lobe; frequently a strong hooked or spined clasper 

 from median basal area; sacculus simple; costa strongly 

 sclerotized but sclerotization rather abruptly terminated 



before apex of harpe. Aedeagus usually partially divided 

 (bifurcate) or armed with projecting spine or spines, 

 rarely simple; penis unarmed (except for a very weak 

 cornutus in/ifscci). Vinculum stout, slightly tapered to 

 truncate or more or less broadly roimded terminal 

 margin. 



Female genitalia without signum; bursa copulatrix 

 usually simple, sometimes with strongly sclerotized, 

 convolute, longitudinal bands near junction of bursa 

 and ductus bursae and extending a short distance into 

 the ductus; ductus bursae short, widening to broad gen- 

 ital opening, usually strongly and elaborately sclero- 

 tized towards genital opening; genital opening rarely 

 simple (fasciolalis, mridisujffusella)] ductus seminalia 

 from biu-sa near junction of bursa and ductus bursae. 



The genus as here defined includes what superficially 

 appears to be two distinct entities, one group of species 

 with gray forewings and another with shiny brown 

 wings, the latter the typical Pyla of authors. For con- 

 venience of identification I am designating them as 

 species groups. The division is not supported by any 

 consistent structural character or combination of char- 

 acters. The differences exhibited by the several species 

 in male and female genitalia, male maxUlary palpi, and 

 male abdominal tufts are striking, but apparently only 

 of specific significance. 



Nothing is known of the food habits or early stages of 

 any of the species except fusca, which is recorded from 

 Erica in the Old World. I suspect that the Ericaceae 

 will prove to be the chief hosts of the genus.

Maxillary palpus of male squamous. 



Forewing gray finely powdered with white, giving the 

 wing an ashy gray appearance; antemedial line distinct 

 throughout, whitish, oblique, notched at top of ceU and 

 on lower fold, bordered outwardly by a black line begin- 

 ning as a black smudge on costa, inwardly by a mod- 

 erately broad black line extending from inner margin to 

 ceU ; subterminal line well marked, bulged at middle and 

 more or less dentate, bordered inwardly by a blackish 

 band and outwardly by a somewhat broader, fainter 

 dark band, these dark borders strongest near costa ; 

 discal dots distinct, small, normally separated, occa- 

 sionally partially coalesced; a row of small black dots 

 along termen. Hind wing smoky white with a pale 

 brownish tint ; veins very faintly darkened ; a narrow dark 

 shade along termen. Alar expanse, 27-30 mm.
