b AMERICAN LEPIDOPTERA. 



The seven species and two varieties may be distinguished 

 as follows : 



1. Forewings without fascia 2. 



Forewings with fascia more or less distinct 5. 



2. Unicolorous, pale yellowish-brown 7. vilella. 



Not yellowish-brown 3 . 



3. Pale grayish-fuscous 4. var. simpliciella. 



Dark fuscous-brown 4 . 



4. Basal two-fifths a shade paler 4. var. fiiscopurpurella. 



Basal two-fifths not paler 1. guilaiidinse. 



5. Fascia straight or slightly curved 6. 



Fascia angulated 7 . 



6. With median costal patch 2. lmlstella. 



Without such a patch 6. distinctella. 



7. Ochreous-fuscous, angle of fascia not very acute..3. yucca^colella. 

 Grayish-fuscous, angle very acute 8. 



8. Discal spot within the fascia 5. sagitella. 



Discal spot beyond the fascia 4. plummerella. 



1. B. guilaiidinre Busck. 



Mr. Busck describes this species as follows : 

 " Antennae dark fuscous, basal joint yellowish ; in the male strongly 

 notched beyond first joint, with pecten on this joint ; shortly ciliated 

 in its entire length ; in female simple, basal joint with pecten. Labial 

 palpi smooth, curved, slender, dark fuscous ; tip somewhat lighter. 

 Tongue stout, scaled at base, coiled at the end. Head and thorax 

 yellowish fuscous; forewings dark fuscous with a somewhat lighter 

 shade before apex and along costa. A small deep black spot on middle 

 of cell, two similar black spots at end of cell, one above the other ; 

 below these an indistinct blackish spot and similar indistinct blackish 

 spots along the apical edge. Cilia yellowish fuscous. Hindwings 

 shining, yellowish fuscous. Abdomen shining, dark fuscous ; anal 

 tuft yellow ; underside whitish, speckled with dark fuscous. Legs 

 yellowish with fuscous shadings on the outside ; hairs above posterior 

 tibiae ashy yellow." Alar expanse 14 mm. 



Bred from Gxdlandina handucella, collected by Dr. Dyar at 

 Palm Beach, Florida, March 5, 1900. 



I have seen the type specimens in the Nat. Mus. Coll. 

 There is some resemblance to Holcocera chalcofrontella, var. 

 fumerella, from which it is sufficiently removed by the vena- 

 tion of the hindwings. The third joint of the labial palpi is 

 very slender and nearly as long as the second.
