brown on the hind border. The caterpillars are about 

 an inch and a half long when fully grown, and of a 

 bluish color, transversely banded with deep orange across 

 the middle of each ring, the band being dotted with 

 black, with head and feet orange ; the top of the eleventh 

 ring somewhat bulging, and the fore part of the body 

 hunched up when the caterpillar is at rest. The cater- 

 pillars begin to appear about the 

 middle of July, and others are 

 hatched afterwards, and as late as

all parts of the leaves, even to the midrib and stalks. 

 When not eating they generally rest upon the underside 

 of the leaves, stretched out as shown in Fig. 91. 



A closely allied species to the last is known as the 

 Pearl Wood Nymph (Eudryas unio, Hubner). The cat- 

 erpillars of the two species are almost identical, while 

 the moths are quite distinct ; for in the latter the brown 

 markings on the wings are neither as large nor as dark 

 in color, while the inner edge of the border of the front 

 wings is wavy, instead of a smooth curved line. Both 

 species of moths rest during the day on the under side 

 of the leaves of the plants upon which 

 they feed, and are only active during 

 the early evening and night. Another 

 species of these blue caterpillars be-

 different genus, is the larvse of The Eight Spotted For- 

 ester (Alypia octomaculata, Fabr). The moths are about 

 the same size of the E. grata, but the wings are black, 

 with eight spots, two on each wing ; those on the fore 

 wings being yellowish, those on the hind wings white. 



The American Procris (Procris Americana, 

 Boisd). This is a small moth of a blue-black color, with 

 a saffron -colored collar and a notched tuft on the extrem- 

 ity of the body. The wings, which are very narrow,
