proportion to size. Entire body slightly invested with short scattered 

 hairs. Two specimens only taken, while feeding upon Acer rubrum. 



Variety B. 



Des. — Length, two and a half inches. General color dark brown, 

 exhibiting in certain parts a decided shade of black. In other particulars 

 identical with Variety A. Found at the base of a pine tree. Most likely 

 had been dislodged therefrom. It had evidently not attained its full 

 size, since it continued to feed for nearly a week afterwards. No appar- 

 ent change was observed in its color from the above, at the time of 

 entering the ground. 



Variety C. 



Des. — Length, nearly three inches. General color light yellowish brown, 

 with a dark median dorsal band an eighth of an inch long, extending 

 from the posterior margin of the pro-thoracic to the beginning of the 

 anal segments ; a much wider one above the line of spiracles, and a 

 similar one above that of the pro-legs. These longitudinal bands were 

 crossed between the rings by transverse ones, similar in color. Spiracles 

 with dark centres and yellowish rims. Entire larva presented a perfectly 

 smooth surface, affording a striking contrast to that of the normal type. 

 Taken upon Acer rubrnni. Six specimens captured. 



Sphinx ^-maculata (normal). 



Des. — Length, three inches. General color, green. Head and oral 

 appendages dark, inclining to black. Lateral, oblique, beaded bands of a 

 light color, seven in number, each band passing obliquely through two 

 segments, from the first abdom.inal to the anal inclusive. Spiracles nearly 

 circular, vv^ith dark centres, surrounded by light annuli. Caudal appen- 

 dage nearly black, somewhat armed v/ith rudimentary spines. Taken in 

 the early part of September, while feeding upon the different varieties of 

 our ordinary white potato, 6'i;/<:7//////7 tuberosum,!^., the common Jamestown 

 AVeed, Datura stramonium, L., and the cultivated tobacco, Nicotiana 

 tabacu?n, L. 



Variety of same. 



Des. — Length, varying from two and a half to two and three-fourth 

 inches. General color dark, bordering on black, rivalling that of the 

 head of the normal form. Lateral oblique bands similarly colored with
