AMERICAN MOTHS OF THE StFBFAMlLY PHYCITINAE 



169 



wing with vein 2 from well before lower outer angle of 

 cell; 3 from the angle connected with 4 by a short 

 spur; 4 and 5 contiguous or anastomosed for about 

 half their lengths; 7 and 8 closely approximate for less 

 than half their lengths; cell less than half the length of 

 wing; discocellular vein curved, produced outwardly at 

 lower angle. Eighth abdominal segment of male with 

 two pairs of ventrolateral hair tufts (the tufts stouter 

 and the hairs broadened and flattened in ochripunctella) . 



Male genitalia with uncus broad, hoodlike. Apical 

 process of gnathos a simple, strongly sclerotized hook. 

 Transtilla absent. Harpe elongate, slender; costa 

 strongly sclerotized on basal half; a strongly sclerotized 

 arm or hook arising from the lower edge of the sclero- 

 tized costa at base ; cucullus narrow, tapering to a blunt 

 point. Anellus Mdth short, weak lateral lobes. Penis 

 without cornuti or other appreciable armature. Vin- 

 culum stout. 



Female genitalia with signa strongly developed, con- 

 sisting of two opposed, densel}"- spined plates (in petrella 

 an additional collar of similar spines about the posterior 

 third of bursa); ductus bursae short, funnel-shaped, 

 sclerotized except at junction with bursa where it is 

 more or less finely scobinate; genital opening simple; 

 ductus seminalis from bursa at junction of the bursa and 

 ductus bursae. 



This and the two genera following {Tola and Ufa) are 

 closely related to Elasmopalpus, and each contains a 

 species withdrawn from the latter genus. Such with- 

 drawal was necessary if Elasmopalpus was to be ac- 

 curately defined. With its previous inclusions such 

 definition was impossible.

Head and thorax reddish brown or brownish ocherous 

 with some gray shading on the mesothorax. 



Forewing brownish gray with a fine white dusting in 

 median area especially toward costa; antemedial line 

 very faint, an irregular, interrupted, fine white line well 

 out on the wing, bordered outwardly by two or three 

 small black dots and preceded by a broad brownish 

 ocherous or reddish brown band ; the inner edge of the 

 latter more or less shaded with black heavily dusted 

 with white ; extreme base of wing shaded with blackish 

 gray; subterminal line usually distinct, narrow, and 

 finely dentate, white with a very weak dark inner border 

 except at costa but, on all well-marked specimens, 

 followed outwardly by some black streaklets on the 

 veins; discal dots separated, black, the lower one always 

 distinct, the upper weaker and sometimes obscured; a 

 ro^^• of small black dots along terminal margin set off 



by a narrow dusting of white. Hind wing pale grayish 

 brown ; the veins slightly darkened ; on most specimens 

 a narrow smoky shade along outer margin. Alar ex- 

 panse, 20-27 mm. 



Male genitalia with terminal margin of uncus rounded 

 and with a very slight notch at apex. Apical process 

 of gnathos a very stout hook. Projecting hook from 

 subcostal base of harpe a long, stout, nearly straight 

 arm, nearly as long as costa of harpe. Aedeagus not 

 appreciably widened towards apex.* Female genitalia 

 with bursa considerably elongated, slender for over half 

 its length and with a collar of strong spines near its 

 middle. 



Type localities: North America {petrella, in Mus. 

 Univ. Berlin); United States (rubiginella and rufinalis, 

 in BM); Florida {hapsella, in AMNH, ex Rutgers). 



Food plant: Unknown. 



Distribution: Florida, Coconut Grove, Glenwood, 

 Lake Alfred (July), Orlando (Feb., Mar., Apr.), St. 

 Petersbm-g (Feb.), Tampa, Vero Beach (Apr., June, 

 Sept., Oct., Dec); Georgia (Feb., Mar.); Texas, Browns- 

 vUle, San Benito, Victoria (Mar.); North Carolina, 

 Raleigh (Apr.), Southern Pines (Aug.), Tryon (May, 

 Aug.); Virginia, Vu-ginia Beach (Aug.); District oj 

 Columbia (May, July); New Jersey, Anglesea (Maj'), 

 Woodbury (May); Iowa, Iowa City (July). 



The Walker species {rubiginella and rufinalis) are 

 included in the synonymy on the strength of Ragonot's 

 reference which is probably correct, for he presumably 

 examined theu- types. I have not. Hulst's hapsella 

 agrees in genitalia and all other characters with typical 

 petrella. Its type is a female, not a male as stated by 

 Hulst. Honora obsipella Hulst is also listed as a 

 synonym of petrella in our lists, but incorrectly. It is 

 a synonym of Hulstia undulatella (see p. 196).

Salebria ochripunctella Dyar, Proc. Ent. Soc. Washington, vol. 

 10, p. 59, 1908.— McDunnough, Check list, No. 6202, 1939. 



Forewing mouse gray; the transverse lines obsolete 

 except for a faint indication of the antemedial line which 

 is oblique, nearly straight, and a dull pale ocherous graj^; 

 a similarly faint ocherous discal spot at end of cell. Ex- 

 cept for these markings the wing is unicolorous. Hind 

 wing subpellucid, whitish with a faint smoky tint at 

 apex and narrowly along terminal margin; the veins 

 not appreciably darkened. Alar expanse, 17-21 mm. 



Male genitalia with uncus slightly constricted towards 

 terminal margin, which is slightly concave; its lateral, 

 apical angles produced into short, ventrally projecting 

 lobes. Apical process of gnathos a small hook. Pro- 

 jecting hook from subcostal base of harpe, curved, about 

 half the length of costa of harpe. Aedeagus enlarged 

 (bulging) towards apex, and with some minute scobina- 



* The lateral projection from near apex of aedeagus shown in 

 our drawing (fig. 411a) is merely a partially sclerotized fragment 

 of the membrane connecting aedeagus and anellus and not a 

 proiecting thorn or spine such as occurs in some species of Pyla.
