Chrysalis. — Of the usual shape, poHshed yellowish brown ; 

 posterior end quite robust, terminates in two short hooks ; length 

 9 mm. 



The lighter colored larvze closely resemble those of Telesilla 

 cinereola, Guenee, which I have bred from ragweed {Ambrosia 

 arteniisicefolid), and from burdock {Lappa officinalis). The last 

 named larvae never have the body tinged with black or purple, 

 and the dorsal space is tinged more or less with white. But the 

 greatest difference between these two larvae is in the markings on 

 the head ; for while in carneola the head is unmarked, in cinereola 

 it is marked with an inverted v-shaped white mark on the face, 

 and a white dash on each side. The larva of Hypcna scabra, 

 Fabricius, which feeds upon clover, closely resembles that of car- 

 neola, but is readily distinguished from it by having only three 

 pairs of abdominal legs, carneola having four pairs. 



The food plants of this species are yellow dock {Rwnex), 

 smartweed {Polygonum pensylvaniciim), and probably golden-rod 

 {Solidago). I have bred the moths from larv?e found feeding upon 

 the two first mentioned plants, and have found upon a golden- 

 rod a larva not differing very much from the above. 



The eggs are deposited either singly or in clusters of from 

 two to four, and in midsummer hatch out in about four days. 

 When jarred from their perch the young larvae hang suspended 

 by a silken thread. When fully grown, they enter the earth and 

 each one forms an oval cavity, in which it spins a thin cocoon. 

 The length of time which they spend in their different stages 

 varies, but is about as follows : First stage, lo days ; second 

 stage, 2 days ; third stage, to entering the earth, 4 days ; enter- 

 ing the earth to imago, 12 to 16 days — completing the cycle from 

 ^ZZ ^o imago in about five weeks. 



Two broods are produced in one season, the imagos of the 

 first brood appearing during the month of July and early in 

 August, those of the second brood passing the winter in the 

 chrysalis state and issuing throughout the month of May of the 

 following year. 



FOOD PLANTS OF TELEA POLYPHEMUS IN THE 

 COUNTY OF YORK, ONTARIO. 



[From a paper read before the Natural History Society of Toronto, by W. Brodie.] 



Riley, in his Missouri report for 1871, gives a list of 19 food 

 plants ; 10 of these, although found here, are not on my list. 

 These 10, with my list, give a total of 49 species.
