890 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxv. 



This species which, by its peculiar coloration, probably imitates bird- 

 droppings can not be mistaken for any other described species and is 

 at once recognized b}^ its pure white head, palpi, and apical third of 

 the forewings. 



GELECHIA FUSCOTyENIAELLA Chambers. 



GelecMa fuscotccniaella Chambers, Bull. U. S. Geol. Snrv., IV, 1878, pp. 89, 143. — 



BuscK, Dyar's List Amer. Lep., No. 5776, 1903. 

 Gelechia fuscotanniella Riley, Smith's List Lep. Bor. Am., No. 5374, 1891. 

 GelecMa fuscolinianella Riley, Smith's List Lep. Bor. Am., No. 5370, 1891. 



Type no. 451 in the U. S. National Museum of this species is labeled 

 by Chiiuiherfi yuscotmuiella, which, through misreading, led Riley to 

 inchidc^ the name fuscoliniaeUd in his list. This name consequently 

 refers to the present species. 



The type is identical with specimens in the Museum of Comparative 

 Zoology in Cambridge, rightly labeled by Chambers. Both are in 

 rather poor condition, but easily recognized from description by the 

 pure white forewings with the sharply limited dark brown base. 



The types are from Texas; in the National Museum there is also a 

 better preserved specimen from Colorado.

GELECHIA ADAPTERELLA Walker. 



Gelechia adapterella Walker, Cat. Lep. Het. Brit. Mus., XXIX, 1864, j). 590.— 

 BusCK, Dyar's List Amer. Lep., No. 5778, 1903. 



This species was omitted in Riley's list. The type should be 

 examined in the British Museum. Habitat not given by Walker. 



GELECHIA ALBISTRIGELLA Chambers. 



Gelechia (tlhistrigella Chambers, Can. Ent., IV, 1872, p. 171.— Hagen, Papilio, 

 IV, 1884, p. 98.— Riley, Smith's List Lep. Bor. Am., No. 5:!04, 1891. 

 BuscK, Dyar's List Amer. Lep., No. 5779, 1903. 



Two types of this species are in the Museum of Comparative; 

 Zoology in Cambridge, but in so poor condition that the}^ can not ba 

 recognized with any degree of positiveness. Thev are, however, prob^ 

 abl}^ authentic, and remind one, as Chambers says, of Strohlsla. As 

 far as can be made but, without injuring the specimens, the forewnngsj 

 which are ol)tusely rounded, have 11 veins, 8 coincident with 7, 3 anc 

 4 stalked, llindwings with 8 veins, 3 and 4 connate, 6 and 7 connatGj 

 Labial palpi with second joint consideral)ly thickened with smoothlj 

 appressed scales, abruptly cut off at apex; terminal joint short 

 than second joint. 



However, it was so difficult to examine these specimens that I fee 

 uncertain a})out ih<^. characters and nuist at present leave the specie 

 as unrecognized.
