The moth expands 10 mm . The head, thorax, and abdomen are densely covered 

 with long hair-like scales, of a dull gray-brown color with bluish reflections. Basal 

 half of primaries of similar color, but with more intermingling of blue and brown 

 scales. About the middle the wing is crossed by a broad, irregularly outlined band 

 of rich brown, sparsely intermingled with silvery scales, and the terminal third is 

 quite evenly mottled in brown and leaden gray, the costal edge of this portion being 

 ornamented with alternate oblique light and dark streaks extending about one- 

 fourth across the wing ; cilia bluish gray ; secondaries lustrous pale brown, shading 

 to cinereous on costal edge ; cilia dingy white. 



Professor Fernald, to whom a specimen was shown, considers it iden- 

 tical with Olemens's S. salicicolana, which I believe breeds in willow galls, 

 but Dr. Eiley pronounces it distinct, and he has types of Olemens's 

 species. 



Gelechia intermediella ? Chambers.— This pretty Tineid appears 

 in its larval form on the tender leaves of apple early in May and again 

 in September. It gnaws the parenchyma from the upper surface, giv- 

 ing the leaves a burned and eroded appearance. 



Larva. — 8 mm in length when mature, slender, cylindrical, tapering slightly in both 

 directions from middle ; incisions deep, giving it a submoniliform appearance. Gen- 

 eral color bluish green, acquiring a purple hue at maturity, with faint longitudinal 

 stripes of cream white. Head pale brown with a tinge of green, ornamented with 

 cream-colored markings on each side and a row of graduated cream-colored dots down 

 the middle of the face. First segment narrow, without perceptible shield. Thoracic 

 legs long, whitish, proceeding from papillated projections on the ventral surface. 



This larva covers the leaves with fine web, in which it moves with 

 great agility, and in which it rests suspended, without touching the 

 surface of the leaf, except when feeding. It is semigregarious and very 

 irregular in its development, some clusters of the leaves showing very 

 recently hatched young, while on other clusters they will be full grown. 

 It pupates on surface of the leaf under a little round cover of dense web, 

 similar to those under which some spiders protect their eggs. The 

 moths emerge in about 3 weeks after pupation and hibernate in the per- 

 fect state. 



Adult. — A beautiful species, expanding 12 or 13 mm . Head and thorax dark gray, 

 more or less suffused with crimson ; palpi dark gray, annulated with rosy white or 

 pale pink. Ground color of primaries leaden gray and rosy white ; scales about 

 evenly intermixed. Three very irregular and variable, often interrupted, bands of 

 rich olive brown cross the wing, intermingled with some light golden brown or 

 ochreous scales ; near the base and center of the wing these form quite distinct 

 patches. The apical third of the wing is margined with alternate dark brown and 

 rosy patches ; cilia gray. Secondaries cinereous, with paler cilia. This species is 

 closely allied to both roseosuffusella Clem., and rubensella Cham., resembling in colora- 

 tion the latter and in size the former. Mr. Chambers says of it : " Intermediate be- 

 tween roseosuffusella Clem., and rubensella Cham., with one or the other of which it 

 has hitherto been confounded. The third joint of the palpi is longer and more 

 acute than in rubensella, more like that of roseosuffusella, but the fore wings are much 

 less roseate than in either of the two other species, frequently showing no tinge of 

 the roseate hue. * * * As in rubensella (and sometimes in roseosuffusella), the first 

 dark band does not cover the base of the wing. The second band is like that of 

 roseosuffusella, but the third extends across the wing, the dorsal portion being, how- 

 ever, paler than the costal, and the costo-apical part of the wing is ochreo -fuscous.
