LIFE HISTORIES OF AMERICAN MOTHS— DYAR. 2G3 



two-thirds to vertex; ocelli black, 5 in a semicircle and one below; 

 jaws with 5 cusps, the upper and lower ones short, the middle one the 

 longest; width 1 mm. Body pale 3'ellow with a black dorsal line on 

 joints 3 to 12, broken at the ends, dotted and not definitely edged. 

 Feet large, pale. Warts moderate, concolorous; hair abundant, long, 

 but of irregular lengths, longer at the ends, joints 3 to 5 and 12, 13; 

 coarsely gray, from a nearly even mixture of black and white; rather 

 stiff, spinulose, the long ones finely pointed. Food greenish; joint 12 

 at the sides a little more yellowish than elsewhere. Later the black 

 dorsal line cuts a series of white, irregularly diamond-shaped dorsal 

 spots on joints 5 to 11, two on each segment, the anterior one smaller, 

 confluent; also a narrow yellow subdorsal line on joints 5 to 11 below 

 wart ii. 



Stage IV. — Head pale yellow, ocelli and jaws ])lack, lal)rum Avhite 

 at tip; broad, rounded, held out flat; width l.S mm. Body and warts 

 colorless, slightly yellowish, especially at the sides of thorax and joint 

 12, sordid green from the food. A broad olivaceous black dorsal 

 stripe, reaching tubercle ii, widened in the centers of the segments, 

 reaching joints 3 and 12, replacing the former white; a yellow subdor- 

 sal line below wart ii on joints 5 to 11, broken in the incisures. Hair 

 irregular, stiff, straight, abundant, black and white, the white much 

 predominating; a number of hairs at the ends much longer; barbuled. 

 Warts i to iii and vi large, almost contiguous; i a little smaller; iv 

 and V minute. Joint 2 retracted, hairless dorsally; joints 3 and 4 

 with one large subdorsal wart. Superficially the larva resembles 

 Hyx^hcmtria cuv.ea. Later the dorsal black becomes again partly white, 

 forming a dorsal white band narrowing at wart i, widening to ii, and 

 containing dorsal and addorsal, somewhat pulverulent, black lines, 

 except posteriorly where the Ijand remains all black. 



Stage Fi— Head round, not bilobed, black, slightly shining, the 

 sutures of the moderate shield-shaped clypeus and median suture nar- 

 rowly olive green as also epistoma and antennw, including ])asal joint; 

 tip of labrum, palpi, and ocelli also pale; width 2.9 mm. Body a 

 little flattened ventrally, arched, a little narrowed at the ends; joint 2 

 retracted and nearly without hairs; anal flap with warts. Warts 

 large, rounded or elliptical, one subdorsal ou joints 3 and -1, a pale 

 space indicating seta iib; on abdomen i to iii and vi large, iv and 

 V small, but distinct warts. Body black dorsally and on centers of 

 segments down to the feet; pale greenish ventrally and in incisures up 

 to the level of wart iv where is a trace of a white stigmatal line, only 

 intersegmeutally. Warts dull flesh color, contrasting with th(> l)ody. 

 Hair mostly black, l)ut mixed Avith gray and white, especially subven- 

 trally, the long hairs at the ends of the body white on the apical third. 

 Hair long, rather even, coarse, spinulose, the long ones at the cuds
