THE CANADIAN ENTOMOLOGIST 21 



Fore wings very narrow, steel-gray, with faint greenish golden 

 reflections, the apex very .slightly tinged with purple. Cilia gray, 

 purple tinged around the apex. Hind wings gray.

Two specimens bred from mines on wild pear, Pyrus communis 

 L., at Cincinnati, (). The mine is a short linear tract, brownish 



green in colour, not exceeding 2 cm. in 

 length and gradually increasing in 

 breadth to the end, where it measures 

 1.5 to 2 mm. across. The cocoon is 

 small, obovoid and greenish brown. 

 There are three generations a year, and 

 mines may be collected in the early part

ol June, in July and during the last part 

 of August. 



Its general pale colour, narrow wings and mall size easily 

 distinguish this species from N. pomivorella Pack, which mines 

 leaves of apple. 



Types in my collection. 



Nepticula apicialbella Chambers 



Nepticula apicialbella Chambers, Can. Ent., V. 127, 1873, 

 Cin. Quart. Jn. Sci., II, 118, 1875; Dyar, List N. A. Lep., No. 6185 

 1902. 



Syn. leucostigma Braun, Jn. Cin. Soc. Nat. Hist., XXI, 88, 

 1912. 



A larger series, among them a flown specimen in which the 

 white scales at the extreme apex are lacking, and merely the apical 

 cilia are white, establishes the synonymy above given Apicial- 

 bella was described from flown specimens. This is the only species 

 I have seen with the oblique fascia. 



Nepticula altella n. sp. 



Palpi silvery gray. Tuft rust red, a little yellowish behind 

 Antenna; fuscous, eye-caps yellowish white. Thorax dark purp- 

 lish brown.
