Stage IV. — Head round, whitish green, a diffuse dark brown shade 

 on the angles of the lobes ; width 1.4 mm. Body short and hunched, 

 thick, somewhat flat, anal feet spreading ; clear green, warts i to v 

 purplish brown, the dorsal and subdorsal lines narrow, broken, white. 

 Hairs very short, fine, but numerous from all the warts, purplish brown 

 mixed with pale. Warts i and ii about in line transversely, iv behind 

 the spiracle, v very remote and below it, vi small, pale, somewhat 

 hidden. Skin finely brown spinulose. Later all the warts i to vi be- 

 came brown, a brown ring around spiracles. Wart ii on joints 2, 5, 

 8, 9 and 1 1 have slightly larger brown spots and these have a slight 

 tendency to form a brown stripe. 



Stage V. — Head rounded, green, wrinkly, black dotted on the 

 angles of the lobes ; width 2.4 mm. Body flattened, short and thick, 

 smaller behind ; feet normal, of good size. Warts nearly obsolete, 

 not elevated ; the hairs, though still numerous, very short and fine, 

 minute, invisible without a lens, so that the larva looks hairless. Soft 

 velvety green, the skin minutely spinulose ; narrow dorsal and broader 

 subdorsal pale lines, faint, not contrasting. All the wart areas faintly 

 marked in velvety red-brown, the spiracles also and tips of feet. The 

 most distinct spots are on the front edge of cervical shield, spiracle of 

 joint 12 and a dorsal patch between the subdorsal lines on joint 13, 

 which are here closely approximated. Hairs on head, anterior edge 

 of joint 2 and anal plate coarser than elsewhere and rather distinct. 

 Spiracles black. The larva narrows much behind and sits on the leat 

 stem which it fits admirably, the brown dorsal spot blending with 

 the bark. With growth the brown spots fade, except at the ends and 

 spiracles, and the warts appear as uncolored scars ; all velvety green, 

 soft, not opaque, quite smooth, the hairs as inconspicuous as the skin 

 spinules. The only marking is the three narrow white lines. At the 

 end of the stage the larva turns sordid waxy-red and leaves the plant. 



Cocoon. — Bored in soft wood or a frail web in a crevice. The 

 larva threw out some dust, but formed no balls of chips. 



Pupa. — Smooth, slightly shining, the cases obscurely wrinkled, 

 and abdominal segments slightly punctured anteriorly ; normal for 

 Noctuidas. Cremaster low, four spines in a transverse row, stout, 

 straight, directed obliquely upward ; a slight ridge on cremaster below 

 each spine. 



Food plant. Viburnum dentatum. The larvae occurred sparingly, 

 solitary, in moist land at Southhaven, L. I.
