sixth, seventh, eighth and ninth rings, and two single rows under the last 

 rings. Spiracles brown. A few very short hairs on each ring, arising singly 

 from little hard points or pit-like, warty substances. Length from one inch 

 to one inch and a fourth. 



Auo-. 17, one of these formed its cocoon of fragments of squash-stalks tied 

 together with a few silken threads. 



A few females, among many specimens of both sexes, are to be found 

 having the abdomen brownish black above, thus corresponding more nearly 

 to Hiibner's satyriniformis; therefore Hu'bner may have had this variety 

 bafore him, when he wrote his description. 



Alypia octomaculata Fabr. 



Found the larvae very small and also nearly full grown on a grape vine 

 some time in June, but the exact date not noted. One grown and two 

 small ones were put into spirit. The others were fed in a pot half fall of 

 earth, in which some of them made their cocoons of earth, lined with a little 

 gummy matter, as is the case in those of jEgeria. One specimen was 

 winged the same summer, August 10th, 1853; probably the pupa state had 

 continued about one month. One specimen remained a chrysalis all winter, 

 and was winged May 25, 1854, in the house. 



June 20, 1854; young larvae, about one fourth to one third of an inch 

 long. They let themselves fall by a thread when disturbed. They feed 

 beneath the leaves, eating them like canker-worms. In confinement they 

 cat the leaves entirely. If touched they will sometimes raise the tail and 

 vibrate it laterally and quickly. 



July 2, 1854. Larvae of various sizes. Very young specimens, not more 

 than three tenths of an inch long, were destitute of the black transverse 

 lines found in older specimens'; they were whitish, tinged with dull orange red 

 on the middle of each segment, and with numerous, irregular, brownish, trans- 

 verse lines between. The dorsal series of tubercles, particularly on the 

 fourth, fifth, sixth and eleventh segments were very prominent, acuminated 

 and brownish black. The others were brown as were also the feet. The 

 head and top of the first and last rings were very pale red, and the dots 

 were obsolete or invisible upon these parts. The side of the eleventh seg- 

 ment was distinctly marked with a white, irregularly shaped spot. The hairs 

 on the tubercles were distinct, but colorless. As the larvae become older 

 and larger, their colors become more intense and with stronger contrasts. 

 The pale orange bands become deep orange; the transverse, brownish lines 

 and the tubercles become deep black; the head, etc. become darker colored, 

 and the black dots upon it are visible to the naked eye. 



Some came to their full size, and went into the earth July 3d, 1854. Fully 

 grown specimens found as late as July 16th, 1854.
