TWO EUROPEAN WEEVILS NEW TO 

 -THE UNITED STATES. 



Mr. F. C. Bowditch has collected Scia 

 philns muricatus a.x\d Strophosomiis coryli in 

 Brookline, Massachusetts. Thirteen speci- 

 mens of the first mentioned species were 

 beaten from balm of gilead, Pnpiiliis bahami- 

 fera, and about the same number of Stro- 

 fhosomus coryli were obtained by sifting. 

 Sometime ago Mr. H. B. Bailey sent me, for 

 identification, four specimens of 5. coryli 

 which he had collected on yellow birch, 

 Betula l/ifea, at South Orange, N. J. In 

 Europe this species has been recorded from 

 birch {Betula), beech {Facru.'i), hazel {Cory- 

 lus), oak (^itercus'), pine {Piitus), and the 

 Scotch broom {Cytisiis acoparitis). Dr. W. G. 

 Dietz identified the species for Mr. Bowditch.

HIBERNATION OF THECLIDI. 

 How many of our T/ieclidipafis the winter in 

 the egg state.'' Last year I found a wintering 

 egg oi liparops on a shadbush {Amelatic/iier 

 canadensis), and this year that of titus on 

 wild cherry in each case in a protected spo*^ 

 on one of the terminal twigs. Several spe- 

 cies of European Tkeclidi, at least five or six 

 of the nine species, are reported to winter as 

 eggs, while of the others perhaps one or 



two winter as chrysalids. Mr. Saunders, 

 then of Lontion, now of Ottawa, years 

 ago obtained the caterpillars of rtc«^/rrt and 

 edivardsii in June before any butterfly is on 

 the wing, so that it is probable that these 

 species also winter in the egg\ and Mr. Hul- 

 bert, of New Britain, last year found cater- 

 pillars of crt/rt;/?<5 during the last of May, so 

 that that species is presumably also in the 

 same category. But I should be gladoffiu-- 

 ther facts regarding them. On the other 

 hand damon {siiiilacis) certainly winters as a 

 chrysalis, and probably all the species of 

 Incisalia, I. augitstus, niphon and irtis, to 

 judge from their earlj' appearance only. How 

 is it with melinits f I suspect this also 

 winters in the chi-ysalis state, but should be 

 glad of any information that can be given.

REARING LEPIDOPTERA. 



In the early times of my entomological 

 work I found much difficulty in obtaining 

 moths from pupae formed "in the ground" — as 

 represented by kegs, deep flower-pots, &c. 

 Three or four years ago I accidentally hit upon 

 a much easier and more successful way of 

 obtaining such pupae, and imagines. A 

 Sphinx drupiferarum larva was forgotten in a 

 close tin, and pupated perfectly without a 

 particle of earth. After finding this pupa. 

 Miss Eliot and I experimented with other 

 sphingidae, Datana ministra, Afiisota sena- 

 toria and other larvae, with the result that 

 of those we allowed to pupate in the ground 

 more than half failed to give the imago, while 

 of those pupating in the close tins very few 

 failed. — Of some kinds every one emerged. 

 With one or two exceptions all those in tin 

 emerged earlier than those in earth, though 

 kept in the saiue room. 



As this plan has been in successful opera- 

 tion for three or four years, and is much 

 simpler and easier than the earth-plan, I ven. 

 ture to recommend it "to all whom it may 

 concern.'"
