NO. 1140. NORTH AMERICAN NOCTUIDAE— SMITH AND DYAB. 109 



concolorous; hair, black and white, rather sparse, a few pale secondary 

 ones subventrally. Later the sides are green; dorsal baud brown with 

 a faint yellow edge and a central reddish dorsal liue; dorsal baud 

 not scalloped by warts II and not exteudiug on joint 13. 



Stage VI. — Head bilobed, black below, the upper half red, contrast- 

 ing; width, 3.5 mm. Joint 12 enlarged and bearing tubercles I and II 

 in a square. Body black with straight, even, yellow lines — dorsal, sub- 

 dorsal (II), lateral (III), and subventral (V), the latter twice as broad 

 as the others, all reaching from the cervical shield to the hump on joint 

 12; a perpeudicular yellow line from wart II on joint 12 to the substig- 

 matal line; joint 13 black above; warts small, pale, the dorsal ones 

 bearing loug white hairs (7 mm.), those on the sides short; a few, nearly 

 obsolete, secondary hairs; length, 26 to 33 mm. The larvae have the 

 habit of elevating the anterior end when disturbed. A single speci- 

 men, apparently destroyed by a fungus, has an abnormally marked 

 head (Plate V, fig. 9«). The larva as shown in fig. 9 was made by Dr. 

 Riley apparently from this specimen, and the coloration can not be 

 reliable. 



Cocoon. — Formed of silk and bits of wood bitten off. 



Pupa. — "Slender and has a curious olive tint" (Thaxter), 



Food plants. — Wild cherry and sugar plum.

Ground color a very even, dark bluish gray, which is shaded with 

 red brown in the basal space inferiorly, and beyond the transverse pos- 

 terior line; most markedly so in the submedian intersjiace. Head and 

 thorax are without distinct markings, except for a black line at the base 

 of the patagiae. The primaries have the transverse markings evident, 

 if not very prominent; the basal line is smoky, geminate, marked on 

 the costa only. The transverse anterior liue is geminate, well marked 

 on the costa, the inner line black to the basal streak, and beyond that 

 more or less lost. The outer portion of the line is marked on the costa, 

 but loses itself in the ground color loug before it reaches the inner mar- 

 gin. As a whole the line is oblique and without distinct curvings. 

 Transverse posterior line geminate on the costa; but beyond that the 

 outer line, which is black, is less distinct. It is broadly bent over the 

 cell, a little toothed on veins 3 and 4, and incurved below that point. 

 There is a vague, irregular, paler subterminal line, and a series of black- 

 ish terminal spots. The basal black streak is very distinct, prominent, 

 with a short spur inferiorly at about the middle, and it reaches through 

 the transverse anterior line. There is a very prominent black streak 

 just above the anal angle, which reaches to, but does not cross, the
