292 Teneina of Colorado. 



The species of Gelechia are much less numerous in this region than 

 in other parts of the United States, as compared Avith species of other 

 genera. 



Plutella. — P. crucifermn, Auct. 



This ubiquitous species was taken at an altitude of 11,500 feet near 

 Berthouds Pass. 



CEcoPHOKA. — CE. boreasella, Cham. 



This species also has a wide range of altitude as well as latitude and 

 longitude. It was first described from a specimen sent to me from 

 London, Ontario, by Mr. Saunders; afterwards I took a specimen in 

 Kentucky, at an altitude of about 1,500 feet, and I have found it on 

 Bellevue Mountain, in the neighborhood of Idaho Springs, at an 

 altitude of about 10,000 feet. 



CE. 4 macuMla (n. sp.) 



The apical half of the antennae is broken off in this specimen before 

 me and the insect has so much the appearance of a Gelechia that I 

 hesitate a little to place it in this genus, notwithstanding the slender 

 palpi and the form and neuration of the hind wings. 



Kich brown ; antennse annulate with white ; forewings each with 

 four white spots, two costal and two dorsal ; the first dorsal is near 

 the basal one-fourth, the second is behind the middle (just before the 

 cilia) ; the first costal is o})posite to the space between the first and 

 second dorsal, and the second costal is a little behind the second dorsal. 

 Hind wings and cilia of both pairs greyish fuscus. Al. ex. over one- 

 half inch. Taken July 28th, at Spanish Bar. Altitude, 7,800 feet. 



GiA'PHiPTERYX. — G. viontisella (n. sp.) 



A very variable species illustrating the insufficiency of the number 

 and position of the white and silvery streaks on the forewings as 

 specific characters in this genus. Taken in great numbers feeding on 

 the flowers of Heliopsis and Helianthus at Spanish Bar. Altitude, 

 7,800 feet. Two or more species might easily be made of single 

 captured specimens, but when the individuals of a species are so 

 abundant as they are in this case, and when all the variations found
