LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 183 



transverse red stripes and two dark cervical spots. Pupation is outside the 

 mine. Occasionally this species is injurious by girdling the twigs and small 

 branches. 



Connecticut to Virginia. 



4. M. fasciella Chambers. Similar to M. salictella; ground lighter, and dis- 

 tinctly brown; each fascia black-edged on the inner side, the first two fasciae equal, 

 and as wide as the space between them; third fascia sometimes broken; second 

 tascia straight; maxillary palpi pale. (JEsyle Chambers, Acrocercops of authors.) 



Quinquenotella Chambers is generally considered an aberration of this species. 

 In it the second fascia is broken into squarish costal and dorsal spots, the dorsal 

 one lying farther out than the costal. 



o. M. opuntiella Busck. Paler and more mottled than salictella; distinctly black- 

 powdered on a whitish ground; first fascia obscure, second only nearly complete; 

 palpus with a black band on third segment; maxillary palpus pale yellowish. 



'ihis species was described from Texas, but probably occurs as far north as the 

 prickly pear, its food plant. The larva makes a long, irregular, winding mine under 

 the epidermis of Opuntia. 



0. M. smilacisella Chambers. Similar to M. salictella, but with the silvery mark- 

 ings more restricted, even the antemedial fascia being sometimes reduced to a bar 

 on inner margin. (Phyllocnistis Chambers.) 



The larva makes a very complexly winding and anastomosing linear mine with 

 a central frass-line on leaves of Smilax hispida and glabra. The mine is about 

 2 mm. wide. 



Cincinnati, Ohio; southern Kentucky. 



7. M. serotinella Busck. Ground dark brown, slightly shining, not powdery. 

 Similar to J/. salictella, but with the first fascia nearly as wide as long, and much 

 widened on the inner margin, with a sharply bent outer boundary; twice as wide 

 as second fascia. Fasciae not black-edged. 



Larva on Prunus serotina (type only seen). 



M. pomonella, a dark species with small alternating spots only, similar to 

 opuntiella, is a western species feeding on apple; and is to be looked for in the 

 north of our territory. 



8. M. apocynella Braun. Head whitish on face, more yellow above, fuscous, as 

 usual, on vertex; palpi whitish, second joint tipped with fuscous; antennae gray. 

 Fore wings black; antemedial fascia straight; an oblique fascia at middle, slightly 

 angulate above inner margin; a larger costal and a minute dorsal one two-thirds 

 way out; a white, costal streak before the apex; tip of fringe whitish. Legs black, 

 annulate \yith white; f(,ur outer segments of tarsi mostly white. 



Larva in a long, whitish, serpentine mine on Apocynum cannabinum; cocoon 

 typical, with bubbles. Larva in early July, the moth later in the month. 



The moth is smaller than salictella, with a yellower head and more oblique 

 median fascia. 



southern Ohio. 



9. M. auratella Braun. Golden bronze; face metallic lead-gray; including 

 antennae; tips of both palpi whitish; fore wing with brilliant, silvery markings; 

 antemedial fascia a fourth way out, wider below fold; an oblique costal streak 

 halfway out, and a more erect one just beyond it on inner margin; triangular 

 costal and dorsal streaks two-thirds way out, nearly meeting; and a fine streak 

 across wing near apex. Apical fringe white. 6% mm. 



There are two broods, in early June and in early August. The larva is a bast- 

 miner in Rudbcckia laciniata (so far as known, only in the cultivated golden 

 glow) and in Dahlia. The mine is long, serpentine, usually tending downward, 

 in .the lower part of the stem. The cocoon is spun in a flap loosened from the 

 cover of the end of the mine, opening not directly outward but by a silk-lined 

 tunnel through the tissues of the flap; it is without pearl globules. This species 

 possibly was introduced, with its food, from Mexico. 



Southern Ohio.
