INSECTS OF THE SOUR GUM. 657 
INSECTS OF THE SWEET GUM. 
Liquidambar styraeiflua. 
1. Ingura prcepilata 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 fifteen 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 ram (.64 inch). (Hy. Edwards and Elliot.) 
2. Hyphantria cunea (Abbot and Smith). 
A large brood of the caterpillars was observed, April 7 and 8, on 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 
the 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 (Gram). Kiley (MS. notes). 
5. Platysamia cecropia (Linn.). Riley (MS. notes). 
6. Actias luna (Linn.). 
7. Callosamia promethea (Drury). 
8. JEacles imperiatis (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 multiflora.) 
AFFECTING THE LEAVES. 
1. Everxjx chcerilus Cramer. 
This sphinx, besides feeding on the leaves of the sour gum (Nyssa 
multiflora), feeds on those of the grape, Virginian creeper (Ampelopsis 
quinquefolia), sheep-berry (Viburnum lentago), arrow-wood (Viburnum 
dentatum), cranberry tree ( Viburnum opulus), clammy azalea (Azalea 
viscosa), and purple azalea (Azalea midiflora). 
Larva. — Head very small, as iu 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
