more or less suffused with orange scales and the orange form less fre- 

 quently with gray scales. This is the most remarkable case of dimor- 

 phism with which I am familiar in the family, and points strongly to the 

 important bearing of biological facts on a true classification. The di- 

 morphic coloring is not sexual, but occurs in both sexes. The eggs of 

 this species are very flat, circular and translucent, with a diameter of 

 0.7 njm , and are laid singly on the underside of the leaf near the mid rib. 

 The species belongs to the genus Tents, and as Packard's specific name 

 oxycoccana has priority, the insect should be known as Teras oxycoccana, 

 Pack. The insect, according to Mr. Brakeley. who gives an account of 

 it in the Eeport of the Seventh Annual Convention of the New Jersey 

 Cranberry Association (1879, p. 7), commonly affects, also, the high-bush 

 whortleberry. The gray form of the moth is most frequent in autumn. 



GELECHIA GALL.ESOLIDAGIXIS, N. Sp.Lan-a. Length 0.60 [inch, - 15 mm ]. Cyl- 

 indrical. Color dark dull-brown, without shine. Largest on middle segments ; taper- 

 ing from 4th to head, and from 9th to extremity. Each segment impressed transversely 

 in the middle, thus forming two folds, the thoracic segment having other such folds. 

 Six small piliferous spots, two each side of dorsuru and one above stigmata, which, 

 together with the stigmata, are shiny and of a lighter brown than the body. Head 

 and cervical shield light shiny-brown. 



Chrysalis. Length 0.50 [inch, = 12.5 mm ]. Mahogany-brown. Form normal. Blunt 

 at extremity. 



Perfect moth. Average length 0.38 [ = 9.5 mm ]. Alar expanse ? 0.95 [inch, = 24 mm ], 

 $ 0.75 [inch, = 18.8 mm J. Fore wings deep purplish-brown, more or less sprinkled 

 with carneous. A light carneous band starts from the costa near the base, and curves 

 towards the middle of the inner margin, which it occupies to a little beyond the be- 

 ginning of the cilia, where it curves upwards towards the tip, reaching only half way 

 up the wing. Here it is approached from above by a somewhat diffuse spot of the 

 same color, which starts from the costa just behind the apex, and runs down to the 

 middle of the wing. 



In the plainly marked individuals there is an extra line running from the middle of 

 the inner margin, outwardly obliquing to the middle of the wing, and then back to 

 the inner margin a little beyond where the cilia commences, but in the great majority 

 of specimens this mark is indistinct. Cilia light carueous. Hind wings slate-gray, 

 with the cilia lighter. Anteume finely aunulated with the same two dark and light 

 colors. Head, thorax and palpi light, with a sprinkling of the dark brown. Body 

 dark, with light aunulations. The species varies in the distiuctn'jss of its markings, 

 and the light parts of the front wing appear finely sprinkled with brown under the 

 lens. Male generally smaller than female, with the antenna; proportionately a little 

 longer. 



Described from numerous bred specimens. 



It seems to resemble G. longifasdeUa of Clemens, in coloration and pattern ; but un- 

 fortunately our late lamented inicrolepidopterist, failed almost always to give the 

 measurement of the species he described, and it is impossible to tell how much mine 

 resembles that species. Yet, as longifcLSciella was described from two mutilated speci- 

 mens, received from A. S. Packard, jr.. and as that gentleman has seen my insect and 

 declared it an nndescnlied species, there can belittle doubt of the fact. [First Rept.,

PTEROPIIORUS CARDUI, X. Sp. Larva. Average length 0.60. Largest in the middle 

 of body, tapering thence each way. Color light straw-yellow greener when young. 

 Somewhat darker, partly translucent, dorsal, >ubdorsal and stigmatal lines. Two 

 lateral rows of black spots, the lower spots rather smaller and placed behind the
