LIFE HISTORY OF ICHTHYURA STRIGOSA GROTE. BY HARRiSON G. DYAR. NEW YORK CITY.
La-roa.
Closely like that of I. aplcalis;
much paler in the early stages, darker in the last stage, the head black, not brown, the body of a dark purplish color, but marked in exactly the same pattern as I. iipicalis. @gs.
Laid in patches of 25 to 50 on the
under side of leaves of Pofulus tre~iwloides at Jefferson Highlands, N. 11 , in June. Somewhat conoidal, not exactly hemispheri- cal, when fresh not shining bright emerald green, later of a purplish color, the heads of the enclosed larvae showing as black spots at the vertices; shell milky while: reticulations evident, neat. but narrow, almost linear and rather small, hexagonal with rounded angles, a small, better marked area at the vertex. Diameter, 8 mm.; height, 5 mm.
On hatching the larvae do not run oft' as @icdis docs, but begin to form their houses without wandering. They are less solitary in habit than a$icalis.
Stage I. Head rather cordate, inou~li
pointed ; shining black; width about 4 mm. Body slightly flattened, grayish white, the slight elevation on joint 12 vinous brown and ail of the sides thinly mottled with the same color; cervical shickl black, anal plate vinous ; thoracic feet btack. The vinous on the sides is vert obscure, being most pronounced in a narrow iubclorsal line. Setx single, long, dark at base, normal, vi absent, though rep- resented by a slight tubercle without seta; leg plate distinct; on thorax no subpritnary setie, vi with two hnirs; the two lower seta; of cervical shield detached. Skin covered with cuticular points.
Stave II. Tubercles converted into
small warts with a few secondary hairs from the skin besides. On abdomen normal, i-i present; on thorax the seta: of i and ii unite to form three warts, the upper one small. Head slightly bilobed, shining black; width 7 mm.
Body pale yellow dorsallv on joints
3 to 12 with three faint purplish lines: cervi- calshield and anal plate smoky; a. central purple spot on joints 5 and 12, the latter joint a little enlarged. A sub-dorsal, purple- brown mottled line and faint molllings on the sides; feet and leg plates dusky. Hairs pale, some of them long. Later the pale
parts predominate so that the body appears multilineate with pale, tlie warts yellow. Stage III.
Width of head 1.1 mm.
Stqe IV. Head bilobed, shining black
with many soft white hairs : medium suture deep, clypeus small, triangular, sunken below the bulging lobes ; width, 2 mm. The body :\upears as before-a whitish ground, trav- ersed by faint triple dorsal, triple approxi- mate lateral and double stigmata1 broken, narrow, purplish brown bands, the dorsal ones faintar than the others. Central dorsal spots behind tubercle i on joints 5 and 12, brown, no humps; warts all yellow. Pri-
mary and secondary hairs soft, pale, .not long. ,
Stag's V Head black, (.he broad, high
clypeus pale, scarcely sunken ; width 3.2 111111. Body as before, the doi-sal patches on joints 5 and 12 much f'ainter; warts conspicnoiisly yellow. The pale brown mottled lines are broader tlmn the five intervening spaces on each side, mottled, pulvernlent on a dirty whitish ground. A single example had the colors brighter, the lines red, "lake red," the three dorsal fainter than the lateriil ones; tubercles yellow, the lateral ones giv- ing the appearance of yellow lines alternat- ing with the lateral red ones (as in Dr. Packard's description). Later as the larvas mature the head becomes nearly entirely
black, the lines dark dull purple, broad, mottled and freckled, reducing the ground color to narrow irregular pale lines. The

general color is very uniform, the warts yel- low but small and inconspicuous. Some of the whitisli lines of the ground color are broken into ring-spots and streaks; about six remain on each side nearly continuous ; the body is therefore dull dark purple, mot- tled with the narrow pale lines and rings and the ?-mall yellow tubercles. Hair very inconspicuous, fine, short, about one from each wart; secondary hair very fine, pilose. Spins an imperfect cocoon between leaves, the moth emerging the following season.
The liirvze have the habits of I. ajicfllis (uait) living- in houses formed of leavesspun together.
