PINE TUBE- WORM. 791 



tricidre of North America, this common European species feeds in 

 Europe on the beech, birch and oak (Heinemaun), and according to 

 Walsh, is in this country an iuquiline in galls of C. salicis-strobiloides. 

 It could not have been mixed with other Tortricids in my breeding tin 

 box, as it was the only Tortricid in the little box, hence I think there 

 is no doubt but that it at least occasionally feeds on the white pine. 

 The larva is very characteristic and easily recognizable. 



Moth, — Costtv full near the base; slightly excavated before the falcate apex; outer 

 margin full and rounded below the apex. Ground color flesh-red brown, with scat- 

 tered leaden scales ; a median white spot, beyond which are a number of lead-colored 

 scales; an oblique row of leaden scales goes from this spot to the costa at a point 

 beyond the inner third of the costa, and the other to a point half way between the 

 costal end of the first liue and the apex ; a few white scales on the first line. Hind 

 wings lead-gray. Length of body 6™'" ; expanse of wings 14 to 16™™. 



124. The pine amorbia. 



Amorbia Immerosana Clemens. 



This leaf-rolling moth was bred from the white pine m Maine, the 

 moth appearing in May. It is a large species of Tortricidfe, the fore 

 wings with the costal edge full. The head, thorax, and forewings are 

 whitish ash, with dark specks, but with no distinct lines and markings. 

 There are two whitish patches in the middle of the forewings. on each 

 side of which are a few fine black specks; in the middle of the outer 

 fourth of the wing is a whitish patch. There is a marginal row of fine 

 black points. The fringe is pale; the hind wings are pale gray slate 

 color. Expanse of wing, 24™™. The larva was not described. It has 

 been bred from the benzoin bush and the poison ivy by Mr. L. W. 

 Goodell. The species ranges from Canada and Maine to Pennsylvania. 



125. The pine tupe-buildek. 



Toririx politana Haworth. 



Order Lepidoptera; family Tortricid^e. 



Cutting off the ends of white pine needles, and spinning together a tube of the 

 stumps, in September, and also to be met with ])robably early in summer, a pale-green 

 leaf-roller, pupating late in September. 



About ten years ago I found, in September, on the young white pines 

 in the grounds of the Massachusetts Agricultural College, at Amherst, 

 Mass., numerous pretty tubes such as are figured in the adjoining en- 

 graving. Thelarva, probably in August and early in September, gathers 

 together about fifteen needles of the white pine, tying them into a bundle 

 by silken threads ; then, usually eating off about one-third of the ends, 

 forms a tube, within which the worm lives. Some full-grown larvje 

 were found September 22 which had gathered the leaves together with- 

 out cutting them olf, the tube extending the whole length of the leaves. 

 It is possible that the larvtie of the first brood early in summer cut off 

 the ends of the tube, while the approach of cold late in September pre-
