Type locality: Verdi, Nev. (type in USNM, 61354). 



Food plant: Unknown. 



Described from unique male collected by A. H. 

 VachelJ, "June 1 to 10." This specimen had been in

306. Pyla TiridigufTusella Barnes and McDunnough 



Figures 381, 851 



Pyla viridisuffuiella Barnes and McDunnough, Canadian Ent., 

 vol. 49, p. 406, 1917.— McDunnough, Check list. No. 6245, 

 1939. 



Maxillary palpus of male in the form of a short 

 aigrette. 



Forewing heavily suffused with light, bronzy green, 

 irridescent scaling, especially strong over basal area and 

 in a line indicating the subterminal line; two transverse 

 blackish bands, an oblique, antemedial one and another 

 forming an inner border to the subterminal line; discal 

 dots, when distinguishable, confluent, forming a line 

 along discocelMar vein. Hind wing very dark brown. 

 Alar expanse, 17-20 mm. 



Male genitalia with harpe simple. Aedeagus bifur- 

 cate to middle, the divided elements asymmetrical (one 

 longer than the other). Female genitalia with a pair 

 of strongly sclerotized, convolute bands extending from 

 posterior end of bursa well into ductus bursae; genital 

 opening simple. 



Type locality: Tuolumne Meadows, Tuolumne 

 County, Calif, (type in USNM). 



Food plant: Unknown. 



Distribution: California, Humphreys Basin (Fresno 

 County, Aug.), Johnsons Park (Sierra Nevada Mts.), 

 Kernick Meadows (9,250 ft., July), Mineralking (Tulare 

 County, July, Aug.), Tuolumne Meadows (July, Aug.). 



The most brilliant of the Pyla species. Its genitalia, 

 both male and female most resemble those of fasciolalis 

 Hulst. 



Genera 77 and 78: Diorydria and Orydometopia 



IVenational division D. Forewing with veins 4 and 6 closely 

 approximate for a short distance from cell {Dioryctria) , or connate 

 or very shortly stalked {Oryctometopia) ; vein 6 straight or bent 

 towards base; 10 from the cell. Hind wing with cell less than 

 one-third the length of wing; discocellular vein curved; veins 4 

 and 5 stalked for at least half their lengths. Male antenna with 

 a shallow sinus or slight incurvation in base of shaft, containing 

 a row of fine spines or a weak scale tuft. Male genitaha with 

 transtiUa incomplete or absent; harpe with costa strongly scle- 

 rotized and produced at apex (Dioryctria) or with one or more 

 short, stout, thornlike spines from lower margin of sacculus.]

Tongue well developed. Antenna finely pubescent 

 or very shortly cihate, rarely unipectinate (in males of 

 some Old World species, pineae Staudinger, mendacella 

 Standinger); on aU males a shallow sinus in base of 

 shaft, containing a short row of minute black, thornlike 

 spines, more or less concealed by rough scaling. Labial 

 palpus upturned, reaching to or a trifle above vertex; 

 second segment grooved on inner side; third segment 

 short (less than one-third the length of second), acumi- 

 nate. Maxillary palpus of male small and squamous or 

 (rarely) in the form of an aigrette. Forewing smooth 

 or with two or more tufts or raised (ruffed) scales; 11 

 veins ; vein 2 from before lower outer angle of cell ; 3 from 

 the angle, slightly nearer to 4 than to 2 at base ; 4 and 5 

 from the cell, approximate at and for about one-fourth 

 their distance from cell; 6 bent towards base and from 

 close to upper angle of cell (in type species, straight and 

 from well below the angle on some specimens); 10 from 

 the cell, approximate to the stalk of 8-9 for some dis- 

 tance beyond ceU; 8 and 9 long stalked; male without 

 costal fold. Hind wing with vein 2 from before lower 

 outer angle of cell ; 3 from the angle, long (almost as long 

 as 2) ; 4 and 5 stalked for half or slightly more than half 

 their lengths; 7 and 8 closely approximate for less than 

 half their lengths beyond ceU; rarely shortly anasto- 

 mosed; cell less than one-third the length of wing; dis- 

 cocellular vein curved, outwardly extended at lower 

 angle. Eighth abdominal segment of male with com- 

 pound ventral scale tufts. 



Male genitalia decidedly elongated (least so in gido- 

 sella). Uncus broad, stout, its terminal margin more or 

 less broadly rounded. Apical process of gnathos a 

 short, stout hook. TranstiUa incomplete or absent; its 

 lateral elements, when distinguishable, slender and 

 usually attached to costal base of harpe. Harpe with 

 costal area broadly sclerotized and produced at apex; 

 cucullus narrowly elongate, bluntly pointed or very 

 narrowly rounded at apex; sacculus short, simple; 

 clasper present, erect, usuaUy finely haired at or near 

 apex, but not bearing strong spines, thorns, or serra- 

 tions. Anellus with well-developed lateral lobes. Ae- 

 deagus long, moderately stout; penis with strong cor- 

 nuti, consisting of numerous straight, slender spines (as 

 long or nearly as long as width of aedeagus) and usually 

 one or more longer, stouter spines placed back of them 

 on the penis. Vinculum stout; longer than broad 

 (frequently considerably elongated), gradually tapering 

 to a moderately broad, rounded, or abruptly angled 

 terminal margin. 



Female genitalia with well-developed signa, consisting 

 of two or three clusters of strong, slender spines, their 

 bases in each of the clusters more or less fused into 

 sclerotized plates; the clusters in end of bursa near
