on the vertex of each lobe, white, containing two black dots; epistoma 

 white. Dots small, niostl}^ uniform, a little strigose and waved, espe- 

 cially in the clypeus: width 1.7 mm. Body norm.al, rather robust; 

 brown-black; a broad distinct, sharply edged, white band, narrowed 

 at the segmental incisures, a similar stigmatal one faintl}" orange 

 blotched boluw and between the spiracles. Subdorsal space velvety, 

 finely white dotted like the head; venter finely lined in whitish, pul- 

 verulently; medio- ventral band rather broad, cloudy triplicate. On 

 thorax the dorsal band replaced by a pair of subdorsal bands, creamy 

 orange tinted, irregular, subconfiuent. On 10-13 dorsal band widened, 

 more irregular and containing black dots; tubercle ii of 12 enlarged, 

 white; anal flap black-brown, white dotted; a white bar from the stig- 

 matal line on the upper halves of the feet of joints 10 and 13. Feet 

 and spiracles black; tubercles small; seta^ fine, short, dark. Seg- 

 ments finely and rather numerously annulate, finelv so anteriorly and 

 posteriorly. 



Eggs from a female taken at Pine Grove, July 19. The larva 

 reached the stage last described September 21) and began to hibernate, 

 but had not enough vitality to survive the winter. It was apparently 

 not mature. It fed on wild cherry and Pf/f/r/on >///>. 



ENEMERA JUTURNARIA Guene'e. 



£^gg. — Elliptical, one diameter much less than the other but not 

 sharply flattened, not depressed at either end; micropylar end roundly 

 truncate, the other abruptlv rounded, both about alike but dift'erenti- 

 ated by the sculpturing; truncation slightly oblique. The two sides are 

 not symmetrical. The eg^ is laid loose, rolling about, and if rolled, 

 alwa3^s stops with the same side up. This side has a single median 

 impressed groove; the lower side two such grooves. Twelve broad, 

 longitudinal, raised ridges join a similar ridge about the rim of the 

 truncation, ])roadly waved, rounded, beaded with a double row of 

 minute pores, joined by difiuse transverse ridges to form squares and 

 also by numerous fine, obscure, transverse lines, about eight to the 

 square. Beginning one square from each end the two central ridges 

 are approximated, the space between depressed as a deep, smooth 

 groove. On the other side the two median hollows are depressed, 

 their bordering ridges less shai*ply approximate, the grooves crossed 

 by strife. In one egg the double grooves began, one of them at one 

 square, the other at two squares from the truncation, but both ended 

 sharply and evenh^ at one square from the other end. In another egg 

 this was reversed. In still another there was but a single groove, but 

 it was not central and was less deeplj^ marked than the dorsal one. 

 Micropylar end coarsely reticulate, the upper end lumpy from the 

 confused ridges. Color green, turning dull pink, with the ridges paler.
