240 Teneina of the United States. 



brown annulus at the base and another about the middle. Vertex, 

 thorax and forewings whitish suffused with ocherous, the forewings 

 marbled as above stated and with an irregular brown spot in the apical 

 part, the basal and dorsal portions however are but little marked with 

 brown : under surface of body, and the legs, pale ocherous, the first pair 

 of legs being distinctly marked with dark brown on the basal joints 

 and but faintly so on the others, except the tarsi which are annulate 

 with dark brown; the intermediate and posterior legs are but faintly 

 marked with dark brown. Al. ex. -^-^ inch. Kentucky. 



The larva feeds in September and October inside of the seed cap- 

 sules of the 'hog weed' (Ambrosia trifida). It, while small, severs the 

 capsule at its base, and eats into it at that point, I have also bred 

 from the same gathering a beautiful little moth, belonging to the Tor- 

 trickke, and I am not certain that I have seen the Gelechia larva when 

 it was very young, as I am inclined to refer all of the very small 

 larva? to the Tortrix. The smallest Gelechia larvffi were already more 

 than one-fourth grown; they are then pale green with the head and 

 shield a little darker green ; the next two segments have each a trans- 

 verse row of six greenish fuscus spots on top and another spot on each 

 side. The remaining segments have each two spots on each side, and 

 on top are two transverse lines or bands of the same greenish fu.^cus 

 hue, the hinder band scalloped near each end, both before and behind. 

 But it is probable that the color and arrangement of the marks varies 

 with each moult, as the larva in its last stage has the head pale fun- 

 gineous with the other segments, yellowish white, and the transverse 

 bands and spots almost obsolete, and very pale dusky green, while two 

 longitudinal pale reddish lines extend along the back on, all the seg- 

 ments except the head. In the breeding jar the larva leaves the cap- 

 sule to pupate, and passes the pupa state among the decaying bracts 

 and small leaves; but frequently like the larvse of G. Hermanella, and 

 some other species it eats its way into the pith of corn stalks or into 

 pieces of cork or other soft substances, and mixes the comminuted par- 

 ticles with its cocoon. 



On page 222, vol. 6, of the Canadian Entomologist, Miss Murtfeldt 

 has mentioned an undescribed species as G. chamhersella and has 

 obligingly favored me with a specimen. It is quite distinct from G. 

 avihrodceeUa though allied to it, and though feeding on a species of 

 Ambrosia it feeds on the leaves and not on the seed. G. ambrosiceella 

 i.s more distinctly marked then Miss Murtfeldt's species, and the wings 

 are clouded with fuscus spots and patches. Some specimens emerge 

 in October and November, some pass the winter the pupa and some in 

 the larva states.
