posterior margin of 12; two lateral on same segments. On segments 

 2 and 3 at the base of the thoracic feet, which are black, is a short 

 line showing only on those two segments and very pale on 8, 9, and 10, 

 at the base of the prolegs. Head yellow at the top, with a black line 

 on each side running from the ocelli to the posterior margin of seg- 

 ment 2, where it passes along the lower edge of the large cervical 

 shield and joins the dark brown color of the body beneath the white 

 lateral line*. Cervical shield yellow, conspicuous, almost covering the 

 second segment, lined at the bottom by the black line that runs from 

 and surrounds the ocelli. Spiracles dark, with pale-edged orifice, con- 

 spicuous on segment 2, where they lie in the short white line at the 

 base of the thoracic feet. Anal shield yellow and conspicuous like the 

 cervical shield, with two dark lines in continuation of the lower edges 

 of the white lateral lines. Tubercles conspicuous, dark brown, shining, 

 piliferous. Dorsal tubercles in two series, the anterior touching the 

 edge of dorsal line and larger than those of the posterior series, which 

 just touch the lateral line. Below the lateral lines are five series of 

 tubercles, one suprastigmatal (No. 3 counting from the dorsum) just 

 beneath lateral line anterior to spiracles Another series (No. 4) on 

 stigmatal line, immediately beneath series No. 3, the tubercle half the 

 size. Another series (No. 5) posterior to spiracles and equidistant with 

 series No. 4 from spiracles, composed of large tubercles, twice the size 

 of those in No. 3. Immediately beneath spiracles and stigmatal folds 

 is series No. 6 of tubercles, not quite as large as those in No. 5. 

 Posterior to this there is a supraventral series (No. 7) of spots slightly 

 larger than those of Na 3. 



On segment 3 are three tubercles in the subdorsal area, a large anterior 

 blotch, and a median row of two spots on each side of the dorsal line. 

 Beneath lateral line are, 1st, two small spots in continuation of the 

 median row, and beneath these two tubercles above ventral fold, the 

 posterior of which is much the larger. The tubercles of the supra- 

 ventral series is on the base of thoracic foot. On segment 4 the tuber- 

 cles are arranged in the same pattern, but the anterior dorsal spot is 

 very small. Segment 12 has but 6 tubercles in a transverse row, two 

 dorsal very large, and the two of series 6 and 7. 



Pupated August 4. Moth emerged Sept. 4, Gortyna cataphracta, 

 male. 



Of several specimens which I have bred from the stems of raspberries 

 and lilies, I found about half pupated (in the breeding jars) in the 

 stems, while others burrowed into the ground. 



Some of the Literature of the Species. 



A brief description of the full-grown larva has also been published by 

 Mr. Wm. Beutenmuller, in the Bulletin of the American Museum of 

 Natural History, vol. v, 1893, p. 94. 



Mr. H. G. Dyar has also described in the Canadian Entomologist, 

 xxiii, 1891, p. 157, the mature larva and pupa of Gortyna cataphracta — 

 the larva " boring in the. leaf-stems of rhubarb, and pupating in its 

 burrow after biting a hole, across which it spins a few threads." The 

 larval description differs in several particulars from the others given,
