with high, contiguous, yellow, orange-tipi)ed tubercles i. 

 Marks as before, except that instead of the later lateral white 

 line is a row of dots. Dorsum all white shaded, subventral 

 region white dotted; stigmatal line narrowly black edged 

 above with black dashes present on the legless segments, but 

 not conspicuously. 



The larvse lives on a perch as H. angulom and JV. ferniyinea 

 in the earlier stages. 



Cocoon. A few threads between leaves. 



Pupa. Cylindrical, tapering a little behind, dark mahog- 

 any brown ; the edges of the segments next to the three move- 

 able incisures sharply cut and nearly black. Cases sha- 

 greened, segments punctured sparsely on the anterior two- 

 thirds. Cremaster two low, divergent cones, each with a 

 short, thick, capitate spine at the tip with one or more small 

 hooks on the lower aspect. Length 29mm., width 7mm. 



Food plants. Oaks (Qaercm velutina, Q. minor). The lar- 

 vae will feed on the rough leaved oaks, contrary to the habit o f 

 N. angulosa. The species is double brooded. 



Teleapolypemus is not a rare m^th in th3 E ist, but the ti j ding 

 of a large number of their cocoons on apple, prune and willow in 

 the vicinity of Los Angeles certainly is of interest, as 1 cm tind no 

 record of their having been taken here before. 



Mr. O. W. Howard sent me 50 cocoons taken as above noted, and 

 he succeeded in raising about 75 by enclosing the moth with netting 

 on our common pepper tree, thus establishing a new food plan 

 for polyphemKs. Early in January three dead cocoons were found 

 well up in the Cahuenga Mountains, northwest of the city, and a 

 number in the brush about the mouth of the San Gabri 1 Canon, 28 

 miles away, so the moth is evidently pretty well established. 



All the Eastern cocoons that I have seen are wrapped in leaves 

 with no attempt to fasten the stems to the twigs, and readily de- 

 tach and fall to the ground, but these were closely woven the full 

 length of the stem, and including the twigs adjoining thus being 

 permanently attached to the tree. The morhs began to enierare May 

 30, and continued to come at the rate of three or four a week until 

 the past few warm days, when five appeared on the board this 

 morning. Frank S. Daggett,
