Until recently this species has been represented only by the unique 

 type in the United States National Museum collection. In 1915, 

 however, Mr. Miller of the Pacific Slope Station at Ashland, Oregon, 

 of the Branch of Forest insects reared several moths from larvae 

 feeding in the cones of Pinus ponderosa (Hopk. U. S. No. 12534e-2) 

 and Pseudotsuga taxifolia (Hopk. U. S. No. 132092) collected at Ash- 

 land, Oregon, by Messrs, Sergent and Keen. Busck's specimen is a 

 male, unfortmiately without an abdomen, collected at Humboldt 

 County, California, in July, and has an expanse of 22 mm. The 

 Oregon specimens average a little smaller (15 to 18 mm.). Otherwise 

 they agree with the type and I believe they are the same species. 

 Mr. Busck has also examined them and verifies my determination. 

 The genitalia of the male is shown in figures 14 and 15. 



GELECHU NATALIS, new species. 



Plate 4, fige. 23, 24. 



Palpi white sprinlded with grayish blue; base of second joint 

 greyish blue; brush well developed, white, with a sprinlding of blue 

 tipped scales; terminal joint grayish blue more or less speckled 

 with white. Face, head, thorax, and forewings white scaled with 

 the tips of the scales bluish, giving the entire insect a grey blue color 

 of varying intensity in different specimens. Costa of forewings 

 in most specimens near the base lighter than the rest of the wing; 

 a faint streak of dark scaling on basal fourth of costa; a similar spot 

 on outer third of costa; near base of cell before middle a faint dark 

 streak, and two dark spots in the cell on its outer costal margin, 

 there often fusing and forming a single short, indistinct, longitudmal 

 streak; in most specimens a narrow, faint, white, outwardly angu- 

 late fascia from just beyond outer third of costa to tornus ; on outer 

 margin of wing at base of cilia 6 or 7 faint dark dots; cilia bluish 

 gray, slightly paler than the wmgs. Hind wmgs pale, a trifle smoky 

 toward apex and along the veins; cilia concolorous. Legs heavily 

 dusted with darker scales on the outer sides, grayish white on the 

 inner. Male genitalia of type as figured; harpes divided, weakly 

 chitinized, costa produced into a narrow, moderately long, fre& 

 arm, rest of harpe greatly reduced; aedoeagus thick and heavily 

 chitinized, tibular at base only terminal two-thirds produced into
