In habitus the moths of Promylea differ strikingly from 

 those of Coptarthria; the transverse lines of forewing 

 being more widely separated and the antemedial line 

 decidedly obUque.

Promylea lunigerella Ragonot, N. Amer. Phycitidae, p. 5, 1887;

 Amer., p. 139, 1890.— McDunnough, Check list, No. 6146, 

 1939, 



Forewing gray or brownish gray, pale in median and 

 most of basal areas and (in many specimens from Van- 

 couver and Washington State) with a faint rosy tint; 

 antemedial line indicated chiefly by its blackish outer 

 border, strongest towards costa and oblique from costa 

 before one-third to inner margin, preceded by reddish 

 brown or ocherous brown patch, broad and inwardly 

 dark-margined on inner margin, attenuated and paling 

 out towards costa; subterminal line pale gray, bordered 

 inwardly by a blackish brown line and outwardly by a 

 much fainter dark line (grayish or reddish brown), out- 

 wardly ciurved between veins 8 and lb; discal dots rarely 

 separated, normally fused into a thin blackish lunule 

 on the discoceUular vein; terminal dots obscure, when 

 distinguishable more or less fused into a line along ter- 

 minal margin. Hind wings pale smoky fuscous ; the veins 

 little if any darkened; a very faint brownish line along 

 termen. Alar expanse, 20-24 mm.

There is nothing to distinguish this from many of our 

 specimens of lunigerella from Washington and British 

 Columbia except some slight differences in genitalia 

 of very doubtful significance, and the name should prob- 

 ably go into synonymy; but untU material is available 

 from intervening areas and something is known of the 

 life history, glendella may be retained as a possible local 

 race. It certainly is nothing more than that. 



Type locality: Glenwood Springs, Colo, (tjrpe in 

 USNM). 



Food plant: Unknown. 



Represented in the National Museum by two males 

 and three females from the type locality (Aug., Sept., 

 Oct.). In addition to the foregoing there are before me 

 five examples of another variety of lunigerella from Fal- 



len Leaf Lake, Calif., Aug. 8 and 12, 1932, H. H. Keifer, 

 collector. They are quite different in color, having 

 paler gray forewings with much fainter transverse dark 

 markings and more whitish hind wings than our other 

 examples of lunigerella. They are probably nothing 

 but a color form and for obvious reasons are going with- 

 out a name at present. 



131. Promylea dyari, new name

 Americana, Lepidoptera Heterocera, vol. 2, p. 564, 1899. 



Dioryctria drucei Dyar, Ins. Insc. Menstr., vol. 7, p. 44, 1919 

 (preoccupied). 



Similar to lunigerella except: Larger and darker; the 

 paler areas of forewing a dark ashy gray; outer black 

 border of antemedial fine broader, forming a small tri- 

 angle on costa; inner border of subterminal fine also 

 slightly stronger, black; the subterminal line itself is 

 more sharply angled below costa and from about vein 6 

 proceeds to inner angle in a slanting almost straight line 

 (a difference that strikes the eye but is hardly signifi- 

 cant; for on some examples of lunigerella the subterminal 

 line is similarly shaped) ; terminal dots confluent, form- 

 ing a conspicuous black line along termen. Alar ex- 

 panse, 30 mm. 



Male genitalia with tegumen and vinculum somewhat 

 stouter (broader in proportion to their width) than those 

 of lunigerella; penis armed with a weak cornutus. 



Type locality: Rinconada, Vera Cruz, Mexico (type 

 in USNM). 



Food plant: Unknown. 



The species is known only from the male type which 

 both Druce and Dyar mistook for a female. The refer- 

 ence to Dioryctria is difficult to understand in Dyar's 

 case; for vein 3 of hind wing is appreciably too short for 

 that genus. The transfer of "Dioryctria drucei Dyar" 

 and "Nephopteryx druceii Ragonot" to the genus Promy- 

 lea makes the former a secondary homsnaym and necessi- 

 tates the new name. It is possible that the two "drucei" 

 represent only different sexes of one species; but this 

 caiOnot be determined without more material of each, so 

 for the present they must be treated as separate species. 



132. Promylea druceii (Ragonot), new combination 

 Figure 722 



Nephopteryx druceii Ragonot, Nouv. Gen., p. 15, 1888; Mono- 

 graph, pt. 1, p. 301, 1893. 



I have not seen any specimens matching Ragonot's de- 

 scription or figure (Monograph, pi. 9, fig. 17) ; but I have 

 before me an excellent photograph of the type supplied 

 by Tarns. This shows a moth similar to dyari but with 

 the dark markings (especially the dark borders of the 

 transverse lines) much more expanded, the outer border 

 of the antemedial line forming a large triangle on costa. 

 According to Ragonot these dark areas have a decided 

 purple tint, rather than the duU black or blackish brown 

 of dyari. The spot on the inner margin before the ante- 

 median line is also piirplish black rather than orange (as
