Forewing brownish gray with some faint whitish dust- 

 ing on basal and median costal areas; antemedial line 

 but slightly oblique, rather faint, dull whitish with a 

 more or less obscured dark outer border; subterminal 

 line obsolete or very faintly indicated; discal dark dots 

 at end of cell separated, only the lower one distinct and 

 always distinguishable. Hind wings dull smoky white 

 to pale fuscous ; veins darkened slightly in several speci- 

 mens; a narrow dark line along termen. Alar expanse, 

 20-24 mm. 



Male genitalia similar to those of coniella except scle- 

 rotized costal margin of harpe abruptly terminated before 

 apex of cucullus and not projecting as a free spur at apex. 

 Female genitalia with a small weak signum; bursa 

 weakly sclerotized, finely scobinate, and with a longi- 

 tudinal sclerotized groove in area near ductus bursae; 

 ductus bursae very short; ductus seminalis from biursa 

 well towards its terminal end. 



Type localities: "North America" {subtetricella, in 

 Paris Mus.); north Illinois {zonulella, in BM); Canada 

 {obnupsella, in AMNH, ex Rutgers). 



Food plant: Unlaiown. 



Distribution: United States: New Hampshire, 

 Hampton; Massachusetts, Cohasset (July), Forest Hills 

 (May, June), Framington (May), Winchendon (May); 

 Pennsylvania, Beaver County (May), New Brighton 

 (May, June), Pittsburgh (May); Illinois, Arlington 

 Heights (May), Chicago (May), (^uincy (June); Ohio, 

 Calla; Florida (no specific locality, Mar.). Canada: 

 Alberta, Bilby (June), Edmonton (May); Manitoba, 

 Aweme (May, June). 



The species is quite distinct and easUy identified by 

 male and female genitalic characters. The Florida rec- 

 ord cited above is from a spurious "tjrpe (male)" of 

 Myelois immundella Hulst, originally in the Fernald Col- 

 lection and now in the U. S. National Museum. It is 

 not immundella, and in genitaha, color and markings 

 agrees perfectly with other males of subtetricella. Rag- 

 onot's zonulella was described from four females in the 

 British Museum labeled "N. lU." and bearing the num- 



ber "82-54." I have examined the genitalia of two of 

 these and they agree in all details with those of the type 

 of subtetricella. As Ragonot designated no holotype I am 

 selecting as lectotype one of the specimens I examined.

 Myelois minutularia (Hulst) McDunnough, Check list. No. 6064, 



1939. 



The status of this species is in doubt. It is known 

 only from females which look like small dark examples 

 of coniella, of which it may be only a race or variety. 

 However, the ductus bursae of minutularia is longer than 

 that of typical coniella and the bursa shows considerably 

 more scobination. Hind wing semihyaline, smoky 

 white. Alar expanse, 11-13 mm. 



Type locality: Blanco County, Tex. (type in 

 AMNH, ex Rutgers). 



Food plant: Unknown. 



The only knoAvn distribution is Texas; examples be- 

 fore me are from Blanco and Burnet Counties. The 

 statement by Hulst in his original description that his 

 types are males is an error. The male is unknown.

Forewing ash gray more or less dusted with fuscous, 

 general color varying from pale ash gray to grayish 

 fuscous (but not so dark as some specimens of coniella) ; 

 antemedial line oblique, indicated by its narrow, black 

 outer border which is shortly and sharply out-angled 

 at middle; subterminal line rather close and paralled 

 to outer margin, sinuate, sharply indented between 

 costa and vein 6, very slightly so at lower fold, often 

 obscure, sometimes with a distinct inwardly bordering 

 black line; discal dots separated, black, lower one (at 

 least) always distinct. Hind wing semihyaline smoky 

 white, somewhat darkened towards apex and with more 

 or less darkening of the veins; a fine dark line along 

 termen. Alar expanse, 20-26 mm. 



Male genitalia with transtilla a thin, weakly 

 sclerotized sub triangulate plate. Harpe with costa 

 broadly sclerotized, produced at apex, but not extending 

 to apex of cucullus. Female genitalia with a small 

 signum; a rather large round area of dorsal surface of 

 bursa thinly sclerotized.
