INSECTS OF THE SOUR GUM. 657 



INSECTS OF THE SWEET GUM. 



Liquidambar sUjraciflua. 

 I. Ingura proepilata Grote. 



The moth has been reared ou sweet gum leaves by Mr. S. Lowell 

 Elliot. 



Larva. — Yellowish apple-green. Second segment with yellow line in front. All 

 the segments have about lifteen to eighteen yellow spots irregularly disposed. Most 

 of these spots are lozenge-shaped, those of the subdorsal region being somewhat 

 linear. Spiracles dull orange, with bright lemon-yellow stigmatal line. Length, 

 16""° (.64 inch). (Hy. Edwards and Elliot.) 



2. Hyphantria cunea (Abbot and Smith). 



A large brood of the caterpillars was observed, April 7 and 8, ou the 

 sweet gum trees at Enterprise, Fla., in the stage of growth preceding 

 the last molt. The caterpillars were very much lighter than I had 

 ever before seen in the Northern States, and I supposed they might be 

 a different species, but the moths on emerging at Providence were of 

 tbe textor, or unspotted form. 



Larva before the last molt. — Body pale greenish yellow, with black dots, which con- 

 trast more with the very light colored body than usual. After the last molt the 

 body is much darker, especially above. 



The following insects also occur on the sweet gum : 



Order Lepidopiera. 



3. Gluphisia trilineata Pack. (S. Lowell Elliot.) 



4. Telea polyphemus (Cram). Kiley (MS. notes). 



5. Platysamia cecropia (Linn.). Riley (MS. notes). 



6. Actias luna (Linn.). 



7. Callosamia promethea (Drury). 



8. Eacles imperialis (Drury). 



9. Phyllocnistis liquidambarisella Chambers. Larva in a long winding 



linear mine in the upper surface of the leaf. (Chambers.) 



INSECTS INJURIOUS TO THE SOUR GUM TREE. 



{Nyssa multijiora.) 



AFFECTING THE LEAVES. 

 1. Everyx chocrilus Cramer. 



This sphinx, besides feeding on the leaves of the sour gum {Nyssa 

 multijiora), feeds on those of the grape, Virginian creeper {Ampelopsis 

 quinquefolia), sheep-herry {Viburnum lentago), arrow-wood {Viburnum 

 dentatum), cranberry tree ( Viburnum opulm), clammy azalea {Azalea 

 viscosa), and purple azalea {Azalea midifora). 



Zarva.— Head very small, as in all the genus, pale yellow green, with a darker 

 median line ; second segment yellow green with numerous irrorations. The spiracles 

 in this segment are orange in the center, pale yellow above and below. In the other
