Triangular plate, labrum, and the bases of antennae pale ; outside of jaws and 

 antenna testaceous ; inside of jaws and eyes black, the latter on a whitish ground. 

 A few black hairs. Body of nearly uniform width, slightly rising dorsally on jointa 

 2-4 ; on joint 5 a long, pointed dorsal process. Joints 7-10 are arched, joint 9 the 

 highest and somewhat humped. The body slopes to joint 11, and at joint 12 is again 

 humped, from whence it tapers to the anal feet. Rows of tubercles, one per seg- 

 ment, each bearing a black hair as follows: — (1) in subdorsal space ou joints 5-12; 

 (2) subdorsal, two tubercles on joint 13, (3) superstigmatal ; (4) substigraatal ; (5) 

 and (6) in subventral space, only one on joint 13, but others on the anal plate. All 

 are small and whitish except in row (1) on joints 5, 9, and 12, where they are orange- 

 red. On joint 5 they surmount the process and are long, pointing upward ; on joint 9 

 rather far apart and surmounting two subconical elevations, and on joint 12 nearer to- 

 gether, surmounting the hump. Body pale brown, mottled with many fine crinkled 

 lines ol red brown ; all of joints 3 and 4, except a dorsal band, green with small black 

 spots laterally. On the posterior part of joint 5, on joints 6 and 7, and the anterior part 

 of joint 8 is an elliptical, creamy white dorsal patch, a little retracted at the segmental 

 sutures and containing three crimson lines. It is supplemented by two white dorsal 

 dots on joint 8. Bordering the patch posteriorly, from joint 7, is a broad blackish 

 dorsal band, continuous on joints 8, 9, and 10, but interrupted on joints 10 and 11 by 

 the usual V-shaped mark. This mark is broad, creamy white, containing some crim- 

 son lines and consists of a subtriangular patch ou joint lU posteriorly and two ob- 

 lique subdorsal bands on Joint 11, between which is a small white dorsal spot. The 

 blackish dorsal band fills in the space between these marks and is continued more 

 narrowly than before to the anal plate. On joints 10 and 11 it has a decided green 

 tinge. The mottliugs on the ground color are much darker on the dorsal line on 

 joints 2-4, on the base of the process and anterior edge of joint 5, bordering the ante- 

 rior part of the pale patch on joints 5-8, and in the subventral space. Spiracles brown, 

 paler centrally in a fine black border. Thoracic feet reddish ; abdominal concolorous- 

 with the body and furnished with a few hairs. The anal feet are partly aborted and 

 are held out straight. Venter pale yellowish on joints 6-13. Length, 30"°™. 



Food-jilants.— 'Maple (Acer), Beech (Fagus), Witch-hazel (Hamarnelis), Linden (Tilia), 

 and probably others. 



Larvse from Dutchess County, New York. 



Mamestra confusa Hiibner. 



Head pale brown ; the lower part of labium and bases of antennae white ; anten- 

 nae black ; ej-es and jaws dark brown. Body semi-transparent, pale whitish, minutely 

 but rather thickly flecked with white. A white dorsal, subdorsal, stigmatal and 

 substigmatal line ; a row of large crimson lateral spots, one per segment, except on 

 joint 13 ; those on joints 2-4 centered with black, the others minutely with white. 

 Spiracles white, bordered by a fine black line ; a few short black hairs. Cervical 

 spot blackish. Feet normal. 



The larva remains concealed by day in a hollow nest composed of a leaf and silk 

 and comes forth to feed. It is not gregarious, and usually but one is found .on the 

 same plant. 



Food-plants. — Maple (Acer), Willow (Salix), Hickory (Carya), Apple (Fyrus), Birch 

 (Betula), and others. I have never found the larva on anything but a tree or bush — 

 contrary to the habits of other species of this genus, which ear herbaceous plants.
