PSYCHE. 



[December 1S96. 



With this article the present series 

 of "Notes on Winter Insects" is 

 brought to a close. In addition to 

 the iS species of Orthoptera, 64 of 

 Hemiptera-Heteroptera and 2S6 of 

 Coleoptera, of which especial mention 

 has lieen made, numerous other forms 

 were taken, the most of which are, as 

 yet, unidentified. 



Among them are some twenty or more 

 species of Coleoptera ; six of Diptera ; 

 twelve winged Hymenoptera, besitles 

 numerous species of ants (among the 

 former being females of Vespa aren- 

 aria and maculata and several species 

 of Bombus and Apis ). Five butterflies 

 were also found in hibernation, viz., 

 Daiiais archippiis Fab., Grapta in- 

 terrogationis Fab., and comma Harr., 

 Pyrameis atalaiitn Linn., and Vanessa 

 antiopa Linn., the last most common, 

 and on the wing on Jan. 2t, 1S94. 



Numerous species of myriapods and 



a number of spiders were also taken and 

 preserved in alcohol, but are not yet 

 identified. 



If, on accoiuit of repetition in giving 

 the detail of places of hibernation, the 

 notes have not been as interesting as 

 they otherwise might have been, I trust 

 tiiat they will go to prove that many 

 insects live as adults through the cold 

 season, and that their places of hiberna- 

 tion are not difficult to find. An ex- 

 tended investigation, carried on through 

 a series of years would undoubtedly 

 show many adiiitional species to hiber- 

 nate in the perfect stage, and if labora- 

 tory investigations were made in con- 

 junction — there might be a solution of 

 one of the great entomological prob- 

 lems ; viz. How can a living insect be 

 frozen solid for weeks and yet retain 

 vitality sufficient to fully recover and 

 perpetuate its kind when the halcyon 

 days of spring roll round once more } 



LIFE HISTORY OF DEILEFHILA LINEATA. 



BY CAROLINE G. SOUr.E, BROOKLIXE, MASS. 



The eggs were sent me by Dr. J. M. 

 Schaffer, from Keokuk, Iowa. Thej were 

 laid on |uly 4th and 5tli., and were ovoid, 

 small in proportion to those of other 

 sphingid moths of the same size as tliis D. 

 liiicata. and yellow green, becoming bluer in 

 a few days. 



July loth they hatched. Tlie young larva 

 was 3^2 '"ch in length, pale green, witli a 

 short, smooth, caudal horn with two setae at 

 the tip, which turned gray. The head was 

 round, had inany gray setae, and was held 

 nearly horizontal. The first segment had a 

 row of setae projecting over the head, and 



the setae of the body were dark enough to be 

 noticed without a glass. The larvae were 

 very active and restless, and dropped by a 

 thread when disturbed. They did not eat 

 their shells, and ate grape-leaves but spar- 

 ingly. 



On the second day some had a distinct 

 brownish-red dorsal line from the now black 

 caudal horn half-way to the head, giving a 

 pinkish look to the posterior part of the body. 

 A few had the first few segments decidedly 

 pinkish and looked (without a glass ) striped 

 longitudinally, the stripes being the black 

 setae, which were most numerous on the
