 the subterminal line, tapering acutely at the outer end ; above 

 this portion another small, tapering white stripe. Terminal 

 line forming a blunt angle at about one-third the width of the 

 wing from the costa. Apex white, with a dark-brown patch.

CRAMBUS CARPENTERELLUS. (Plate I., fig. 5.) 

 Crambus carpenterellus Pack., Rep. Hayd. Surv., p. 548 (1873). 



Expanse of wings, 28 mm. Head, palpi and thorax tawny 

 ochreous. Fore wings ochreous fuscous, with a white stripe 

 starting from the base and extending to near the subterminal 

 line, where it ends in a point ; at the basal third, a tooth on 

 the costal side, and another one at the outer third on the 

 opposite side, which ends in a dark line extending half the 

 distance to the cross-line. Between this line and the point 

 of the streak three other dark lines, parallel to this and 

 gradually growing shorter, arise from the white streak. 

 Below the streak the wing is lighter in color than elsewhere. 

 Subterminal line bordered with white on the costa, slightly 

 curving in its first third, nearly straight the remainder of 

 its course and followed outwardly by a silvery line. Upon 

 the apex a brown triangle with a white triangle above it. 

 A series of five dark-brown marginal dashes. Fringes sil- 

 very fuscous. Hind wings much paler. 



Habitat. Mountains of Colorado. Early stages and
