Labial palpi, face and head white; anteniiii? with brown annulations. 

 Thorax white; patag-ina golden 3'ellow. Forewing's golden 3'ellow, 

 mottled with silver}- white, as follows: A narrow basal central streak 

 reaching to basal third; a small basal dorsal spot, two costal and two 

 dorsal rather ill-detined outwardly oblique streaks meeting or nearly 

 meeting at the center of the wing; a series of small costal and dorsal 

 apical dots round the tip of the wing. Extreme apex black. Cilia 

 golden 3'ellow, with silver^' base. Hind wings pale ochreous fuscous. 

 Forewings with veins 7 and S stalked. 



Alar expanse. — 8-9 mm. 



Food plant. — Junlperus.

1 have examined the t3'pe of fveiidla at Merton Plall, England, and 

 also Zeller's specimens of the supposed ahdominal'ix.^ which are in the 

 Musemn of Comparative Zoology. There is, as suggested b3' Lord 

 Walsingham, no doubt that they are identical but difierent from the 

 true ahdoriiinalis of Europe, which thus should be excluded from our 

 American list. 



In the U. S. National Museum is a large series, compared with the 

 t3'pe, bred in the insectar3' of LJ. S. Department of Agricultun? from 

 Juniperas., received from Cadet, Missouri. 



This series was wrongl3'^ placed and labeled as Bucculatrlx thaleUa 

 Packard. (See p. 23.)

Head, face and palpi white; antenna? annulated with black. 

 Thorax white. Forewings silvery white, largel}"^ suppressed b3^ the 

 extensive golden-yellow markings which caused Chambers to regard 

 that color as the groundcolor. The basal costal part of the wing is 

 light goklen and reaches on the costa out to a darker golden, inwardl3^ 

 oblique, broad fascia on the middle of the wing; this fascia is edged 

 and parti}" overlaid with dark brownish scales on its dorsal half. The 

 white groundcolor occupies the dorsal base of the wing and projects 

 as a spur up along the central fascia nearly to the costal edge; it also
