Sept., 1908.] KEARFOTT : TORIkKIHl AM) TlNEINA. 187 



Described from twelve specimens and many cases all taken in 

 the Central Experiment Farms at Ottawa, Ontario, feeding on 

 Elceagnus argentea and the closely allied Hippophoe rhamnoides and 

 Shepherdia argentea. I am indebted to Dr. James Fletcher for the 

 botanical names and to both him and Mr. Arthur Gibson for collecting 

 the winter cases. 



Type in my collection. 



In the middle of June, 1907, the mature cases were found most 

 abundantly, in fact so much so, that the shrubs of Elceagnus and allied 

 plants very perceptibly showed the effect of the operations of the 

 larvae. The latter were not sufficiently full fed at this date and only 

 one completed its transformations on July, 24. In 1908 Mr. Gibson 

 sent me about twenty mature cases, which produced eleven specimens 

 between July 4 and 25. 



Nepticula 9lingerlandella, new species. 



Expanse 3.5 to 5 mm. 



Head and frontal tuft orange, antenna eye-caps and side tufts white ; antenna 

 whitish gray ; thorax bronzy black ; abdomen light gray ; legs yellowish white, pos- 

 terior tarsi finely ringed with black. 



Foreiving. — Bronzy black with a shining white fascia at outer third. Cilia and 

 hind wings light gray. 



Type in my collection, numerous topotypes in Cornell University 

 collection ; all bred from blotch mines on leaves of plum in domestic 

 orchards near Rochester, X. V.,by Prof. M. V. Slingerland, in whose 

 honor the species is named. In a forthcoming bulletin Professor 

 Slingerland will give a detailed account of the life history. 



Incurvaria? dietziella, new species (PI. Ill, Fig. 6). 



Expanse 6.5 to 10.5 mm. 



Antenna finely serrate, thick, about two thirds as long as forewing, purplish 

 black. Labial palpi short, do not extend beyond face, clothed with long yellow 

 hairs mixed with brown. Max. palpi, if present, probably short, folded, concealed by 

 dense hairs on face. Tongue well developed, scaled above. Eyes round, prominent, 

 wide apart. Ocelli present. Head and face covered with long, light ochreous yellow 

 hairs. Abdomen bronzy black. Legs, anterior and middle pair bronzy black, poster- 

 ior pair grayish brown, whitish at joints and the tibiae much thickened with appressed 

 scales, from the upper side of which are emitted a dense pencil or cluster of hair-like 

 scales. 



Forewing. — Ovate-lanceolate, obtusely pointed at apex ; 12 veins, 2 from lower 

 angle of cell, 7 and S stalked both to costa ; I 6 furcate at base. Cell widened in 

 outer third by absorption of accessory vein. Between 3 and 9 transverse vein is not 

 tubular. Color bronzy black, finely dotted with metallic blue. The ground color by 

 reflected light is golden and purple bronze ; the thorax exhibits the same reflections. 

 Cilia grayish below apex, above concolorous.
