I know this species only from the above description, and it 
may not be correctly placed in this genus. 
48. Nepticula belfrageella Cliaml)pr.s 
A'cpticula belfrageella Chainliers, Can. Ent., vii, 7r>, 1S7.5; Dyar’s Xo. 6187. 
“Face ])ale 3 ’ellowi.sh ; eye-caps white; antennae brown; thorax and prima- 
ries pale gray, darker toward the apex of tlie primaries, and with a fuscous spot 
at the apex. Al. ex. from 2\ to over three lines. Season, April.” 
, Locality . — Bosque County, Te.xas (C’hambers). 
49. Nepticuia latifascielia Chambers 
Nepticula latifasciella Chambers, Bull. Geol. Surv. Terr., iv, 106, 1878; Braun, 
Can. Ent., xlvi, 18, 1914; Dyar’s X"o. 6200. 
Tuft on the face ocherous, dark brown on the vertex; collar and e}'e-caps 
cream}'. Thorax and extreme base of fore wings creamy-buflf. Remainder of 
fore wing deep purple brown, with a very broad creamy-buff fascia just before 
the middle; two or three crearny-buff scales at the extreme apex forming with 
the creamy-vhite cilia around the apex a conspicuous pale spot. Cilia else- 
where gray. Hind wings and cilia gray. Legs creamy-buff, outer surfaces 
fuscous. Abdomen dark brown. 
Expanse. — 4 to 4. .5 mm. 
Localities . — Kentucky (Chambers); Falls Church, Virginia 
(Busck); Ohio; Allegheny^ County, Bennsylvania (Alarloff). 
The larvae mine leaves of red and scarlet oaks, and probably 
chestnut (Chamliers). Although the mine varies in length from 
3 to 5 cm. on different species of oak, with a breadth of about 1.5 
mm. at its end, it has in general the same appearance (Fig. 47). 
The frass is at first deposited in a broad lilackish line through the 
center, later dispersed across the entire breadth, and toward the 
end collected into a broad band. The larva is bright green and 
escapes from the mine through the lower epidermis of the leaf. 
Cocoon whitish or occasionally ochraceous. 
This is one of the earliest species to appear in the spring; moths 
maybe found resting on tree trunks during the latter part of April. 
Mines may be found in June, the latter part of July, in Septem- 
ber, and often during late October. 
50. Nepticula crataegifoliella Clemens

No. Am., 173, 1872; Braun, Can. Ent., xlvi, 17, 1914; Dyar’s Xo. 6194. 
Palpi pale oeherous. Tuft ocherous, faintly tinged with red above. An- 
tennae ocherous, partly suffused with fuscous, eye-caps ocherous. Thorax
