of September. It is cylindrical and snbmoniliform ; tapers an- 

 teriorly and posteriorly ; with punctiform points and isolated 

 hairs ; first segment with rather abundant dorsal hairs ; three 

 pairs of thoracic feet and five abdominal pairs. Head small, 

 ellipsoidal, brown ; body dark yellowish green, tinged with red- 

 dish anteriorly ; hairs blackish and short. Early in October the 

 larva enters the pupa state, wearing an elongated, dirty white, 

 ribbed cocoon, and appears as an imago during the latter part of 

 the following April, or early in May." The present species 

 seems to be undescribed, and may be called Bucculalrix thuiella. 

 It belongs to the extensive Tineid family, and its general ap- 

 pearance is sufficiently indicated by the drawing. The body and 

 wings are pearly white, and the antennae are white, with brown 

 wings, while there is a low broad tuft of white scales between 

 the antennjB, the crest being much flatter than in the species 

 living on the apple. The fore wings are white, and crossed in 

 the middle by a broad brown band, and beyond this band by 

 alternating white and brown stripes, crossing from the front edge 

 (costa) of the wing. On the end of the wing, and in the middle 

 of the outer edge, is a conspicuous black spot, like the eye in a 

 peacock's feather. To describe the wing and its markings more 

 fully, — the basal half of the wing is white, unspotted, except a 

 short, transverse brown band, extending from the inner edge, 

 not quite to the middle of the wing. On each side of this 

 band is a row of two or three minute dots. The middle band is 

 broadest on the hind edge. Beyond and arising from the costa, 

 where they are broadest, and extending to the opposite side of 

 the wing, are six brown lines, alternating with white interspaces. 

 These lines run together in the middle of the wing, brown dots 

 being added, but which end as distinct lines on the inner end 

 of the wing. The three outermost lines are much curved, and, 

 with the curve of the fringe, form a circular area, in the middle 

 of which, on the base of the fringe, is the curvilinear, rather 

 thick, dark brown spot. The longfringe on the end of the wing 

 is white at base, and brown at the end. The hind wings are pale 

 brown, acutely pointed, with a long silvery fringe. The tibiae 

 and tarsi of the fore legs are brownish, while the hind legs are 

 white, with a long fringe on the hindermost tibiaj. The length 

 of one fore wing is .18 j and the length of the body is .18 inch. 

 The cocoon is white, tough, dense, slender cylindrical, and
