the orange band extcndino- across the legless joints. Legs black, false legs with 

 two black spots on an orange ground, at their outer base. A lateral white wavy band, 

 obsolete ou the thoracic joints, and most conspicuous on 10 and 11, running just below 

 the spiracles, and interrupted by the transverse orange band, and sometimes obsolete 

 in front of it. 



Five specimens examined, taken onVitis. Harris {Correspondence, p. 2SQ) enunic- 

 rates only 6 black stripes between the orange bands, as he did not count the two bor- 

 dering the same. "When young this worm is whitish with brown transverse lines, the 

 colors not contrasting so strongly as in the more mature individuals, though the black 

 spots are relatively more conspicuous and the hairs springing from them longer. 



In habit this worm is much like the Beautiful Wood Nym ph, and 

 like it there are two broods each year, and Maj. J. R. Muhleman of 

 Woodburn, Ills., informs me that in 1870 he obtained a third. 



This larva transforms to chrysalis within a very slight cocoon 

 formed without silk, upon or just below the surface of the earth, and 

 issues soon after as a very beautiful moth of a deep blue-black color, 

 with orange thanks, yellow shoulder pieces, each of the front wings 

 with two large, light yellow spots, and each of the hind wings with 

 two white ones. The illustration (Fig. 55, c) represents the female, 

 and the male differs from her in having the wing spots larger, and in 

 having a conspicuous white mark along the top of his narrower ab- 

 domen. 



This insect is more common with us than in the New England 

 States. I have found it on the Concord, Taylor and Wild ripari'C, 

 but on no other genus of plants. It is sometimes extremely abun- 

 dant; and Mr. T. A. Gates, of Massilon, Iowa, suffered much, last fall, 

 from the depredations of a worm determined as this species by Dr. Le 

 Baron. 



SUMMARY. 



We thus have at least three, and probably four distinct grape-vine 

 worms which, while they belong to three distinct genera, are yet of 

 the same family, and so closely resemble each other in general ap- 

 pearance that none but the practiced entomologist would be likely to 

 distinguish between them, l^o.l {PsyoJioinorpha ejjimenis) is the 

 smallest species, has no orange bands in the middle of the body, and 

 but four black transverse stripes, to each joint, on a white ground. 

 It is our commonest speciest, is single-brooded, and found only in 

 spring. No. 3 {Eudryas ^/'«i!a), and No. 3 {E. unio) are not easily 

 distinguishable except in the average larger size and comparatively 

 larger hump of the former: but are easily separated from the others 

 by having six transverse black stripes to the joint, on a bluish-white 

 ground. They are seldom abundant in Missouri, being more at home 

 farther north, and are most abundant in late summer and fall, as there is
