NORTH AMERICAN NEPTICULIDAE 
Four specimens, in the National Museum collection, bred from 
mines on leaves of cranberry {Oxycoccus macrocarpus). The 
mine (Fig. 21) is a serpentine track, closety following the margin 
of the leaf for the greater part of its length; it is sometimes bent 
back on itself, but then the two parts are contiguous. Cocoon 
ocherous. The imagoes appeared in i\Iay and July. 
This species is closely allied to N. ostryaefolieUa in which, how- 
ever, the entire tuft is ochraceous and the fascia is a little more 
posterior. 
21. Nepticula myricafoliella Busck 
Nepticula myricafoliella Busck, Proc. U. S. Nat. Mus., xxiii, 238, 1900; Dyar’s 
No. (5204. 
“Antennae silvery fuscous, extreme tip white. Face and head tufted, light 
golden yellow. Eye-caps silvery white. Thorax and fore wing deej) bluish 
black with strong metallic reflections. At two-thirds from base is a transverse, 
silvery white fascia, a little broader on the dorsal than on the costal edge. 
Dorsal cilia at the fascia white; rest of cilia dark pur]:)li.sh gray. Hind wing 
light gray. Abdomen shining black above, silvery below. Legs ])urplish. 
All tarsi white. 
“Alar expanse, 2.8 mm.” 
Locality . — Florida (Dyar). 
The specimens, from which the above description by Mr. Busck 
was made, were bred from upper serpentine mines on Myrica 
cerifera. The mine (Fig. 22) is extremely narrow, measuring 
scarcely 1 mm. across at the extreme end where the larva makes 
its exit. 
22. Xepticula altella Braun 
Nepticula altella Braun, Can. Ent., xlvi, 21, 1914. 
Tuft orange-ochraceous in front, becoming pale behind. Antennae fuscous, 
eye-caps creamy white. Thorax dark purplish browm. Fore wings before the 
fascia purple brown, beyond it brown with purple reflections; the general 
color to the naked eye is deep purple before the fascia and browm beyond it. 
A silvery fascia crosses the wing at three-fifths, and is usually a little broader 
on the margins of the wings. Cilia gray, hind wings deep purple, becoming 
brown towmrd the tip. Legs fuscous, tarsi of the middle and hind pair silvery. 
Abdomen purplish browm. 
Expanse. — 6.5 to 7 mm. 
Locality .—Southwestern Ohio, locally in pin oak forests. 
The species has but one generation a j^ear; moths appear in 
May. The mines occur on the first leaves of the pin oak {Quercus 
palustris) that appear in the spring, never on the leaves that come
