Psorosa texanella Hulst, Canadian Ent., vol. 32, p. 174, 1900. 

 Hulstea texanella (Hulst), U, S. Nat. Mus. BuU. 52, p. 432, 1903.— 

 McDunnough, Check list, No. 6342, 1939. (New synonymy.) 



Similar to celtidella in color and maculation except: 

 Ocherous basal area of forewing more or less shaded with 

 reddish purple and similar suffusions over much of the 

 median and outer areas; also a broad blackish suffusion 

 over the area of the antemedial line and extending some- 

 what beyond it; the inner dark border of subtermiaal 

 line more nearly continuous and the outer bordering 

 dashes much fainter except in dark and very well 

 marked examples. Alar expanse, 17-20 mm. 



Male genitalia figured from type of texanella Hulst, 

 which agree in every detail with those of typical rubri- 

 sfarsella and of the male type of croceella. They differ 

 from those of celtidella in having a longer, more strongly 

 sclerotized clasper, and different cornuti (shown in lat- 

 eral view in our figxu-es). The cornuti lie side by side 

 in both celtidella and rubrisparsella, but in the former 

 species they are of equal length while in rubrisparsella, 

 one cornutus is much shorter than the other — ^not too 

 reliable a character, but apparently consistent here. 

 Transtilla, on dissection, distinguishable as a complete 

 band, but central area very weak and in balsam prepa- 

 ration only the well sclerotized lateral elements easily 

 seen. 



Female genitalia with a broad granulate band par- 

 tially encircling middle of bursa, similar to that in sub- 

 fv^cella except that in subjuscella it is chiefly over the 

 ventral surface of bursa while m. rubrisparsella it is on 

 the dorsal. 



Type localities: United States {rubrisparsella, in 

 Paris Mus.); Texas (rufibasella, in Paris Mus.); Blanco 

 Coimty, Tex. {croceella and texanella, in AMNH, ex 

 Eutgers). 



Food plant: Celtis. 



Distribution: Texas, Black Jack Springs, Blanco 

 County, KerrvHle (June); Oklahoma; Missouri, St. 

 Louis (June); Illinois, Lacon (July), Putnam County 

 (July); West Virginia, Jefferson County (Aug.); Mary- 

 land, Plummers Isl.; District of Columbia, Washington 

 (May, June). 



Very close to celtidella and distinguished from it 

 chiefly by its genitaUa and squamous male maxillary 

 palpi. Hulst's texanella was described from an ab- 

 normal specimen with vein 4 lacking in the hind wing. 

 I have before me two similar abnormal females (from 

 Oklahoma and Illinois) and in the following species 

 {gilvibasella) a couple of examples, out of a long series 

 of normal specimens, that also have vein 4 absent. 



The type of croceella in addition to the Hulst name 

 label also bears the following label in Ragonot's hand- 

 writing: "Nephopteryx rubrisparsella Ti&g.=rwfibasella 

 Rag."

Salebria lacteella Hulst, Canadian Ent., vol. 32, p. 71, 1900. — 

 Barnes and McDunnough, Contributions, vol. 3, p. 197, 

 1916. 



Much paler than the preceding species {rubrisparsella) 

 and without its blackish shadings. Ground color pale 

 gray with a very faint bluish tint; extreme base of wing 

 ocherous orange, this shade extended somewhat on 

 inner margin and indicated on many specimens in 

 median area over the lower fold; a broad band of the 

 same color immediately preceding the antemedial line 

 and extending from inner margin to middle of cell; 

 above it a blackish shade extending to costa; lower half 

 of antemedial line clearly indicated, narrow, whitish, 

 bordered outwardly by a narrow black line which fuses 

 towards costa into the blackish shade above the ocher- 

 ous patch; subterminal line faintly bordered inwardly 

 by a faint blackish line; discal dots small, separated, 

 sometimes obscure, but usually distinct; a row of weak 

 but discernible blackish dots along termen. Hind wing 

 subpeUucid; whitish with a very faint ocherous tint; a 

 weak, pale brown Une along tei-men; the veins not 

 appreciably darkened. Alar expanse, 17-20 mm. 



Male genitalia similar to those of rubrisparsella. The 

 eighth-segment tufts much simpler, reduced to two 

 lateral pairs with scales of a uniform shape and size. 



Female genitalia with a broad granulate band on 

 biu-sa similar to that in rubrisparsella; bursa bulged into 

 a small, strongly granulate lobe at its left posterior 

 angle (this lobe opposite to that giving off ductus 

 seminalis) ; also a narrow row of moderately long spines 

 across upper side of bursa at junction of bursa and 

 ductus bursae. 



Ttpe localities: Not given {gUvibaseUa, in AMNH, 

 ex Rutgers) ; Blanco Coimty, Tex. {lacteella, in AMNH, 

 ex Rutgers). 



Food plant: Unknown. 



Distbibution: Texas, Blanco County (Sept.), 

 Brownsville (Mar., July), San Benito (Mar., Apr., 

 May, July, Aug., Sept.). 



The species is close to but distinct from rubrisparsella. 

 The types of gilvibasella and lacteella are both females 

 with identical genitalia. A long series from Browns- 

 ville and San Benito are before me.

Forewing ash gray more or less suffused by somber 

 purplish or gray brown, shading into blackish brown on 

 the borders of the transverse liaes; the pale color limited 

 to a rather narrow band preceding the inner border of 

 the antemedial line, part of the median area following
