process bearing tubercles iib and iv+v. A 

 rounded process bearing tubercle ii of joint 

 8. Dorsal tubercles all slightly elevated ; 

 anal prongs short, projecting. Slatv black 

 dorsally, a little bronzy, shading to sordid 

 ocherous ventrally. mottled and streaked with 

 black. Collar of joint 3 flesh colored before ; 

 processes orange spotted ; orange dots on 

 tubercles ii, iv and v and a larger one outside 

 the finger process of joint S. Foot of joint 10 

 brightly shaded outwardly. A black blotch on 

 joint 8 subventrally. Thoracic and anal feet 

 dark. Setae small except on the anal plate 

 and with the hair tubercles black. The lar\ a 

 bends the head and joint 2 downward, forming 

 an angle at joint 3, the feet of 4 crossing the 

 others, making the anterior end look thick 

 and club-shaped. 



Stage V. Head shaped as before, but the 

 back of the occiput covered by joint 2 ; lab- 

 rum quadrate, emarginate, epistoma broad, 

 clypeus triangular; purplish gray, thickly 

 mottled on a white ground, somewhat spiral- 

 ly over the faces of the lobes; eyes black; 

 last joint of antennae long and reddish; 

 width 3.2 mm. Body as before, a little inten- 

 sified in the characters. Joints 2 and 3 ante- 

 riorly abruptly rising to a high collared 

 elevation on joint 3, angled subdorsally by 

 the double finger processes. Dorsum de- 

 scending to joint 5, then cylindrical and 

 smooth (except for the small, produced 

 tubercles, tubercle ii most produced) to joint 

 12, but tubercle ii of joint S very large, form- 

 ing a high, club-shaped papilla; tubercle ii 

 of joint 12 also prominent, but to a less 

 degree. Anal plate rounded behind, the leg 

 shield not produced posteriorly, the prongs 

 thick, moderate. Purplish brown like bark, 

 densely mottled, shields paler, the outside 

 of the foot of joint 10 especially so; collar 

 black, an orange patch before it, mottled ; 

 finger processes tipped with red; tubercles i to 

 v form bright orange cushions hearing the 

 black hair tubercle; tubercles vi and vii 

 black all a little elevated. Spiracles white, 

 black rimmed. Setae short, black, distinct. 



The half of the larva below the spiracles is 

 lighter, more grayish than the dorsum; the 

 base of the foot of joint 4 and venter of joint 8 

 are darkly shaded, also subdorsally on joint 

 12 and the papilla of joint 8. Later the 

 ground color becomes alike all over, slightly 

 ocherous gray, like bark, the marks the same, 

 the dark patclies more contrasted. 



Spun among leaves on the ground. The 

 eggs were found April 30th, on a chestnut 

 twig, having apparently passed the winter 

 in this state. The larvae began spinning 

 about June ist and the first moth appeared 

 Julv 1st. The species therefore seems to be 

 double brooded with hibernation in the egg 

 state. The larvae were fed on oak till the 

 developing leaves became too hard for their 

 weak mandibles, after which they ate pear 

 leaves. They seem to be general feeders for 

 any leaves not too hard. Larvae from 

 Washington, D. C. 



SUPPLEMENTARY NOTES ON 

 ORGYIA. 



In Psyche vii, 340 (1896) I published 

 some '■ final notes on Orgyia," giving a list 

 of the American species of Notolophus. 

 Since then some additional facts have come 

 to light. 



Nololophiis o.t/f?;/ Barnes, Can. ent., xxxii, 

 45 (Feb., 1900); libera Strecker, Suppl. 3, 

 Lep. Rhop. & Het., 29 (Mar., 1900). 



This newly discovered form from the 

 Rocky Mountain region is still unknown in 

 the larva. It will prove of much interest, as 

 the moth lies between antitpta and t'etusta, 

 two species hitherto not considered allied.

 300 (1S90). 



I shall have to allow this form specific 

 standing. Mr. Beutenmiiller not long since 

 collected .additional material in Florida which 

 shows a moth nearly allied to dejinila and 

 possessing, like it, wool-covered eggs. He 

 kindly directed me to the exact spot where 

 his collections were made and I found there
