 and vertical to the hind margin. Subterminal line curved 

 within the apex, then running to the hind margin. Both 

 of these lines are faint, and the subterminal is edged on the 

 outside with silvery scales. Terminal row of black dots in 

 a straight line, not following the margin at the lower part, 

 where it rounds outwardly. Fringes silvery metallic. Hind 

 wings white, slightly stained with pale fuscous on the apex.

CR AMBUS BOLTERELLUS. (Plate II., fig. 15.) 

 Crambus bolterellus Fern., Ent. Am., Vol. III., p. 37 (1887). 



Expanse of wings, 22 mm. Palpi, head and thorax pale 

 ochre-yellow, the palpi touched with fuscous on the outer 

 side ; patagiai overlaid with lead-colored scales. Fore wings 

 white, broadly edged with fuscous on the costa ; behind this 

 edging a dull-colored stripe extending from the basal fourth 

 of the cell to the apex, the remaining intervenular spaces of 

 the same color. An oblique reddish-brown line crosses the 

 w r ing a little beyond the end of the cell, with a slight inward 

 angle near vein 2 and a strong outward angle beyond the 

 end of the cell. A second line crosses the wing rather more 

 than half way between the other and the outer margin, of 

 the same color and similarly angulated below the costa, but 

 following the outline of the outer margin below the angle. 

 A row of six or seven black points on the intervenular 

 spaces, at the end of the wing. Fringes pale silvery metal- 

 lic. Hind wings dull white, with a pale fuscous terminal 

 line not reaching the anal angle. Fringes white.
