recorded as having been taken rarely in Ohio and Illinois. Beyond 

 this, but little is known of its distribution in the United States. It is 

 said to occur in the circumpolar regions of Europe. Boisdaval received 

 examjDles of it from Greenland and Lapland.

Caterpillars of this moth were received from Scarsdale, Westchester 

 Co., N. Y., on February seventh, with a statement that they had just 

 made their appearance in a green-house and were injuring the foliage. 

 Some method of destroying them was desired. 



They are of small size, as are most of the family of Tortricidw to 

 which they belong, not much exceeding one-half inch in length, slender, 

 and nearly cylindrical. They are of an apple-green color, of a trans- 

 parency that permits the pulsation of the dorsal vessel (correspond- 

 ing to a heart) to be seen through the skin, and are traversed by a 

 dark dorsal line. The twelve segments of the body are well defined, 

 each bearing several small tubercles or papilloc which give out a small 

 white hair — the four on the back (the trapezoidal spots) being the 

 most conspicuous. The head is flat and shining black, with some 

 whitish hairs, and the collar (upper part of the first segment) is also 

 shining black. The three pairs of legs are black; the prolegs green. 



This species was named and described by Dr. Clemens as Antithesia 

 nimbatana, in I860, and was later referred to the genus Penthina. It 

 is a common species in the vicinity of Albany. 



Mr. D. W. Coquillett states {loc. cit.) that he has found the cater- 

 pillar of this species to be " utterly indistinguishable from a black- 

 headed variety of Caccecia rosaceaiia (Harris)." I have not compared 

 the two, but the moths are so exceedingly unlike that their larvae 

 certainly should show differential features. From my recollection of 

 the larva of P. nimbatana, its green is more yellowish and clearer than
