Xylomyges ochrea Hampson 1909: 273. Spodoptera ochrea; Todd & Poole 1980: 733; Poole 1989: Diagnosis. — Forewing streaking much lighter than in S. albula and S. eridania. Ground color cream. Reniform spot pale gray and indistinct
projecting arms on upper third of tegumen (Fig. 36). Female genitalia with median projection of ventral plate of ostium bursa shorter than in S. albula, and with a broadly round distal margin (Fig. 445); fine dense scales on 8th segment black.
Description. Adult Male. — Head: Basal segment of labial palpus cream with a few rufous scales; median segment cream variably mixed with rufous and black scales and mixed with black and brown scales in basal half, cream apically; apical segment cream. Frons with short scales white; long scales cream and rufous, or light brown; lateral spots at eye margin rufous (can coalesce into a bar); vertex white (speckled with brown). Antenna filiform; scape white; flagellum white.
Thorax: Patagium cream to light brown (a few specks of black in some specimens). Tegula cream to light brown (a few specks of black in some specimens). Mesothorax cream. Underside of thorax white. Prothoracic femur cream, fuscous, and rufous; tibia with lateral scale tufts not extending beyond first tarsal segment, cream (some scales tipped with a combination of fuscous and rufous), subapical spot absent; tarsal segments cream. Mesothoracic femur cream; tibia cream and rufous, inner spur more than twice length of outer spur, mediolateral surface devoid of scales on large spur; tarsal segments cream. Metathoracic femur cream; tibia cream and rufous; tarsal segments cream.
Forewing: Length, 11.5-14 mm; ground color cream; basal line absent; R vein not a contrasting color; basal scale patch between R and Cu veins absent; basal half circle scale patch below Cu vein absent; antemedial line absent; claviform spot absent; basal scale patch absent; gray patch covering anal cell and half of cell CuA2 absent; oblique
brown mark from fifth outer marginal spot to vein CuA2 absent; curved white line from antemedial line to postmedial line absent; orbicular spot round, white, very faint, with a few brown scales in center; reniform spot pale gray, indistinct; white scales along Cu vein and bases of M3 and CuAl veins absent; postmedial line absent; postmedian band undifferentiated; black scale patches in middle of cells in postmedian area absent; subterminal line absent; apex lacking a white patch; minute black spots along outer margin; fringe pale gray to buff. Underside ground color white with cream on leading edge and along veins; outer margin with black spots; reniform spot darker, indistinct.
Hindwing: Ground color white; no other markings, immaculate; fringe white. Underside ground color white; costal cells C and Sc white speckled with gray scales; no spot on underside.
Abdomen: Dorsum white to cream; venter cream and gray; disto-lateral black spots on sternites absent; 8th tergite with spiculate patches absent on caudal margin.
Genitalia: Uncus evenly curved; slender, gradually narrowing toward pointed apex; setae absent or few. Scaphium elongate, weakly developed. Tegumen with lateral swellings at basal twothirds. Costa convex (Figs. 319, 349). Costal process narrow, elongate; at base of costa on inner edge; perpendicular to costa of valve. Cucullus broadly rounded. Anellifer with lightly sclerotized plate bearing setae absent. Ampulla short, triangular shaped lobe, apex round. Clasper proper apex round, curved toward sacculus (Figs. 319, 349). Clavus absent. Sacculus broad to half its length, tapering distally; apex pointed. Valvula narrower than valve; well differentiated from valve, apex free; apex produced and curved toward costa; indentation absent. Coremata moderately elongate, approximately 0.5 or less length of valve; composed of a single lobe. Juxta a narrow rectangular band, median process wide at base and constricted near apical third, ventral margin a broad inverted V-shape. Anellus with a patch of enlarged spines at apex of aedoeagus. Vinculum round. Aedoeagus straight; coecum equal in diameter to shaft; patch of spines absent on apex of membranous sheath surrounding aedoeagus. Vesica curving ventrally; short, less than 0.75 length of aedoeagus; apicobasal cornutal patch a wide ribbon; elongate, extending beyond middle
of vesica; cornuti in form of minute flat granules; lateral cornutal patch a wide elongate ribbon; composed of short, conical spines; dense cornutal patch at apex of vesica; distal cornutus absent.
Adult Female. Essentially as described for male except:
Forewing: Length, 13-16.5 mm.
Abdomen: Fine dense scales on 8th segment gray.
Genitalia: Ventral plate of ostium bursa wider than high; distal margin with a single median projection; ventrolateral invaginated pocket of 8th sternite absent. Ductus bursae moderately elongate (length 2-3 times width); completely sclerotized. Appendix bursae membranous. Corpus bursae bulbous, length less than twice width; a few striae. Signum in apical half of corpus bursae; elongate, length greater than 1.15 mm; almost vertical.
