UNITED STATES NATIONAL MUSEUM BULLETIN" 207 



a small tuft in lower fold just beyond antemedial line; 

 dark gray finely peppered with white making the ground 

 color a dark ash gray; the subbasal scale ridge, outer 

 border of antemedial and inner border of subterminal 

 lines, and the small raised patch following antemedial 

 line, black strongly contrasted against the ground 

 color, the outer border of antemedial line somewhat 

 fainter than the other black markings; subbasal scale 

 ridge narrow, reaching almost to costa; between it and 

 antemedial line a broad pale band; antemedial line 

 obscure, indicated chiefly by its blackish outer bordering 

 Une which is almost vertical and parallel with the scale 

 ridge; subterminal line also faint, pale gray, outwardly 

 angled at middle, bordered inwardly by a narrow black 

 line; discal spot obscure, a narrow grayish white line on 

 discocellular vein; a fine, strongly contrasted, black line 

 along terminal margin. Hind wing white, on female a 

 faint smoky tint towards apex; the outer parts of the 

 veins faintly darkened and a narrow brown line along 

 terminal margin. Alar expanse, 23-25 mm. 



Male genitalia with uncus rather short in proportion 

 to width; its terminal margin broadly rounded. Harpe 

 narrow and rather short. Penis armed with two 

 groups of subterminal spines and a single, straight, 

 slender, rather short posterior spine; one of the anterior 

 groups consisting of a line of short spines along lateral 

 margin of penis near its apex. 



Type localitt: Fort Wingate, N. Mex, (type in 

 USNM, 61356). 



Food plant: Unknown. 



Described from male type and one female paratype 

 from the type locality (July), and one female from Glen- 

 wood Springs, Colo. (Sept.) which McDmmough had 

 identified as gulosella Hulst. They are superficially 

 similar to the type of that species except for the stronger 

 contrast of the black markings on fore wing; but are 

 easily separated by their radically different genitalia. 

 The expanded (bulbous) shape of the caudal end of the 

 female ductus bursae is found in only one other Ameri- 

 can species of Dioryctria {clarioralis) and there in a 

 lesser degree.

MaxiUary palpus of male squamous. 



Forewing with a weak subbasal ridge of raised scales 

 (the species has always been included in the smooth- 

 winged Dioryctria group, but unrubbed and unpressed 

 examples always show some traces of a raised subbasal 

 ridge) ; ground color grayish brown with black patches 

 and more or less white shading in the median and ter- 

 minal areas; a broad blackish band preceding the ante- 

 medial line, paling towards inner margin, bordered in- 



wardly by the black raised-scale ridge and outwardly by 

 the thin, black inner border of the antemedial line; the 

 latter thin, obhque, sometimes weakly notched below 

 costa and more rarely at lower fold, white without (or 

 with only an occasional trace, near inner margin) the 

 normal black outer bordering hne; a more or less ex- 

 tended black smudge in cell, sometimes extended as 

 far as the black inner border of subterminal line and 

 usually completely obhterating any trace of a white 

 discal spot; some white streaking on lower vein of cell; 

 subtermraal hne distinct, sharply indented between 

 costa and vein 5, thence vertical and straight to inner 

 margin, whitish with a thin black inner border; a fine 

 line of confluent black dots along terminal margin. 

 Hind wing smoky gray or brownish; the veins more or 

 less darkened; a fine dark line along termen. Alar 

 expanse, 22-29 mm. 



Male genitalia with uncus triangulate, appreciably 

 longer than greatest width, evenly tapering to very 

 narrowly rounded apex. Female with ductus biu:sae 

 broadened near genital opening but less so than in 

 subtracta; bursa much larger and more heavily spined 

 than that of subtracta, at least as long as ductus bursae. 



Type localities: "United States" (clarioralis, in 

 BM); Tryon, N. C. (brunneella, in USNM). 



Food plant: Pinus palustris. This record from a 

 specimen received from L. A. Hetrick reared from larva 

 feeding in the cone. 



Distribution: Florida, Dunediu (Mar.), Fort Myers 

 (Apr.), Miami; North Carolina, Tryon (May, June); 

 Massachusetts, Martha's Vineyard (June, July). 



Another intermediate between the smooth-winged 

 and rough-scaled species, easily distinguished by its 

 genitaUa and wtog pattern.

 pt. 1, p. 153, 1893. — Janse, Joum. Ent. Soc. South Africa, 

 vol. 4, p. 156, 1941. (Type of genus: Oryctometopia fossula- 

 tella Ragonot.) 



Tongue well developed. Antenna of male with a 

 slight sinus and scale tuft in base of shaft; pubescent. 

 Labial palpus obliquely upturned, reaching to or a trifle 

 above vertex; third segment about two-thirds the length 

 of second, bluntly pointed, more or less deflected for- 

 ward. Maxillary palpi of both sexes broadly squamous, 

 the scales forming a flat cover over the face. Forewing 

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

 outer angle of cell; 3 from the angle, equidistant at base 

 from 2 and 4, parallel with 2 from just beyond base for 

 its remaining length; 4 and 5 connate or very shortly 

 stalked; 6 from below upper angle of cell, straight; 8 

 and 9 stalked for about two-thirds the length of 8; 10 

 from the cell, approximate to stalk of 8-9 at base; male 

 with costal fold containing a row of coarse scales. Hind 

 wing with vein 2 from before lower outer angle of cell; 

 3 from the angle; 4 and 5 stalked for about half their 

 lengths; 7 and 8 closely approxim;ate beyond cell at least 

 for half their lengths; all veins long; cell about one- 

 fourth the length of wing; discocelliilar vein slightly
