No.i3(M. REVISION OF AMERICAN GELECHIID MOTHS— BUSCK. 879 



The unique tj^pe of this species is found in the Cambridge Museum 

 in excellent condition. A good bred series in the U. S. National 

 Museum carefully compared with the type bears tbe designation 

 " U. S. Dept. of Agriculture Insectary, Nos. 4232 and 5786," and the 

 corresponding ri^cords show that it has been bred twice, first from 

 larva skeletonizing leaves of cottonwood, received from El Paso, 

 Texas, in November, 1887, from which the moths issued in January 

 next year. The note on the larva is very short: 



Greenish white, with a ])ink bhish on dorsal surface. 



Secondly, it was received in July, 1893, from Jetsam, Wj^oming, 

 with the report that the larvae were extremeh" injurious to cotton- 

 wood. With this is the following note on the larva: 



Head pale brown, with posterior margin black; ])ody pale yellowish white without 

 any markings. The moths issued July 3 to 8. 



The Texan specimens average a little lighter and smaller than those 

 from Wj'oming, l)ut they are undoubtedly same species. The type, 

 although from Texas, agrees with the darker Wj'oming specimens. 

 Finally, there is in the National Museum one specimen of this species, 

 bred 1)}" Dr. Dyar from cottonwood in Colorado. 



This species is (^xtremely similar to the following in ornamentation 

 and easily mixed with it. The palpi, however, give a good distin- 

 guishing character. In the present species the brush is normal and 

 well developed, longer at l)ase than at apex of second joint, while 

 Geleehia lynceeUa has a very short and even brush. The palpi also 

 show color differences as pointed out by Zeller.
