AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



25 



edge; inner margin from base to antemedial line nar- 

 rowly bordered by reddish scales; subterminal line 

 narrow, slightly outcurved between vein 6 and lower 

 fold, pale gray, inwardly bordered by a narrow black 

 line; a blackish fuscous patch outwardly bordering the 

 antemedial line from costa to cell ; a similar dark shade 

 on costa near apex; these blackish patches shading into 

 the dark central area of wing; black discal dots at end 

 of cell distinct and separate; some obsciu-e dull red 

 shading in terminal area toward tornus; along termen 

 a narrow discontinuous black line. Hind wing pale 

 smoky fuscous with veins, terminal margin, and apical 

 area darker. Alar expanse, 16-20 mm. 



Male genitalia similar to those of caliginella except 

 transtilla broader at apex and arms of anellus stouter. 

 Female genitalia differing from those of caliginella 

 chiefly in that there are no patches of small scobina- 

 tions in bursa near its junction with ductus bursae. 



Type locality.: Vancouver, British Columbia 

 (type in Canadian Nat. Coll.). 



Food plant: Cotoneaster. 



Known so far only from the type series from Van- 

 couver. It is distinguished from caliginella chiefly by 

 its generally darker color. 



4. Genus Trachycera Ragonot 



Trachycera Ragonot, Monograph, pt. 1, p. 2, 1893. (Type of 

 genus, Rhodophaea pallicornella Ragonot.) 



This genus is close to Rhodophaea, being distinguished 

 from it chiefly by male characters. The male of 

 pallicornella from which these were drawn is apparently 

 lost. Clarke was unable to locate it at Paris, where it 

 should have been; and, as no other males agreeing with 

 Ragonot's description or figure (Monograph, pi. 5, 

 fig. 20) are available, we are unable to check his charac- 

 ters. Ragonot separates Trachycera from Rhodophaea 

 widely in his generic key (Monograph, pt. 1, pp. xliii 

 and xliv) on the basis of the trifid or bifid condition of 

 the median vein of hind wing. This is an error, how- 

 ever, for the true Rhodophaea species are no more bifid 

 than is Trachycera. The female of pallicornella has 

 essentially the same venation as the type of Rhodophaea 

 (advenella). 



The distinguishing male characters given by Ragonot 

 are: Serratiform male antenna; very short labial palpus 

 (scarcely reaching to middle of face); and minute maxil- 

 lary palpus. 



The female has a pair of small signa in the bursa 

 copulatrix, developed as granulate cups (as in Davara).

The holotype of pallicornella is a female labeled in 

 Ragonot's handwriting "ty. or. PI. V, fig. 20." Accord- 

 ing to Clarke the Ragonot figure represents it accu-

rately. Unfortunately it is a mended specimen and 

 the glued-on abdomen is spurious. Its genitalia are 

 pyraustine rather then phycitid. 



I have before me a female which is an exact match for 

 Ragonot's figure. It is somewhat smaller (15 mm.) 

 than the type ("19 mm.") but this difference is easily 

 within the normal range for many species of medium- 

 sized Phycitinae. It was collected at Devils River, 

 Tex. (May). The genitalia are figured from this 

 specimen. 



Forewing pale gray with some blackish dusting on 

 base, especially on base of costa; a faint purplish gray 

 shade on lower part of postmedian area; antemedial 

 band rather broad, red narrowly lined with black on 

 inner and outer sides, the back outer margin somewhat 

 widened at costa; subterminal line narrow, nearly 

 vertical, with an outward bulge between vein 6 and 

 lower fold, whitish, bordered inwardly by a narrow 

 black line and by a black outer patch at costa near apex ; 

 discal and terminal dots obsolete. Hind wing dull 

 whitish with a faint yellow tint and shading to pale 

 fuscous towards apex. Alar expanse, 15-19 mm. 



Type locality: Texas (type in Paris Mus.), 



Food plant: Unknown. 



5. Anabasis, new genus 



Type of genus: Myelois ochrodesma ZeUar. 



Tongue well developed. Antenna pubescent; on 

 male, basal segment enlarged and angulate (as in 

 Acrohasis), shaft simple. Labial palpus upturned 

 reaching to vertex (slightly longer on female than on 

 male). Maxillary palpus rather broadly scaled. Fore- 

 wing with a transverse, antemedian ridge of raised 

 scales; 11 veins; vein 2 from before but near lower 

 outer angle of cell; 3 from the angle, approximate to 2 

 at base, nearer to 2 than to 4 ; 4 and 5 closely approxi- 

 mate for some distance from base; 6 from below upper 

 angle of cell, slightly bent towards base; 10 from the 

 cell; male without costal fold. Hind wing with vein 2 

 from well before lower outer angle of cell ; 3 from before 

 but very near the angle ; 4 and 5 from the angle, closely 

 contiguous (or more or less anastomosed) for about 

 half their lengths ; 7 and 8 contiguous or weakly anasto- 

 mosed for some distance beyond cell; cell one-third 

 the length of wing; discocellvdar vein curved. Eighth 

 abdominal segment of male with ventral hair tuft and 

 a pair of modified, ventrolateral tufts. 



Genitalic characters as in Acrohasis except: Harpe 

 with a transverse, sclerotized ridge from base of costa 

 to lower outer angle of sacculus; a cluster of modified 

 scales on outer edge of inner margin in the angle be- 

 tween sacculus and cucuUus; terminal margin of 

 vinculum more rounded. (These may be only specific 

 characters.) 



A development from and quite close to Acrohasis, 

 which it replaces in tropical America; distinguished 

 from that genus chiefly by shorter cell and the con- 

 tiguous position of veins 4 and 5 of hind wing. Except
