the common bud-worm in not having any transverse rows of teeth 

 around the body. The moth is of an ashen gray color above, 

 whitish and lustrous like satin beneath. The fore wings are 

 very narrow, and are sprinkled with a few black dots, three of 

 which near the middle are larger than the rest. The hind wings 

 are also narrow, blackish, and surrounded by very broad fringes. 

 The antennae are bristle-formed. The palpi, or feelers, project 

 horizontally from the head, in the form of a brush-like snout, and 

 from the middle of the upper side of each of them arises the 

 curved and pointed terminal joint, like a little spur. The tongue 

 is spirally rolled, and, when extended, measures about half the 

 length of the antennse. This little moth rests with the forepart 

 of the body slightly elevated, the narrow wings horizontally in- 

 cumbent upon the body, and the antennse turned backwards and 

 lying straight upon the wings. The insect may be seen on 

 the wing in the evening, soon after sunset; and it may also be 

 found, in considerable numbers, among the grass, at a somewhat 

 earlier hour. 



Some hope may be entertained that the little parasites, alluded 

 to in the foregoing account, may tend greatly to check the future 

 undue increase of the palmer-worms. Should a second genera- 

 tion of the latter appear during the present summer, or should we 

 have another visitation of them next year, or at any future time, 

 some means for arresting their depredations may become ne- 

 cessary. Showering the trees with soap-suds, or a solution of 

 whale-oil soap, or with lime-water, dusting ashes or air-slacked 

 lime on the leaves, when wet with dew or rain, or casting dry 

 sand upon the trees, may be found serviceable. 



Dr. Burnett stated, on the authority of Prof. Dana, that, 

 in Connecticut, the canker-worm always disappeared on or 

 about the 10th of June. Being in New Haven at that time, 

 Dr. Burnett confirmed this statement by his own observa- 

 tion. The worms were very numerous on the 4th and 5th ; 

 on the 9th, Prof. Dana said there would be none on the 

 next day ; and the event accorded with the statement, the 

 worms having almost all disappeared. It seems probable,
