Habits of the Glowworm, 625 



to any improper treatment, or whether they required longer 

 time to arrive at maturity, a second experiment may be the 

 means of convincing me. But to return to my chrysalides : 

 the first, a female, arrived at perfection on the 30th of May; 

 the second, a male, on the 3d of June ; and the third, a 

 female, on the 5th. The skin of the chrysalis is so transparent, 

 that the perfect insect, whether male or female, is easily dis- 

 tinguished through it. 



I propose making a second experiment, if I can meet with 

 a few glowworms this approaching summer. — W. H. White. 

 Old Kent Road, Feb. 6. 1835. 



Localities near London in which the Glowworm has occurred. 

 — I have seen glowworms in a friend's possession, at different 

 periods, brought from Hendon and other places near London ; 

 and I have known them to be found on the banks of the 

 ditches at Kennington Common. — James Fennell. Temple 9

Notice of certain Characteristic Differences between the Larva 

 and Imago of the Glowworm. — The larva of the glowworm 

 has the thirteen segments of the body, each laterally marked 

 with a reddish spot ; the female imago is generally without 

 any trace of this : the larva is velvety black ; the imago brown 

 and somewhat glabrous ; the larva is longer and narrower ; 

 the imago broader and shorter : the larva gives an uncertain 

 and intermitting light from the telum (Newman) andparatelum 

 (Newman) only; the imago gives a bright and continuous light 

 from the decator (Newman), protelum (Newman), paratelum, 

 and telum : the antennae and legs of the imago have their 

 parts fully developed ; the same parts, in the larva, are rudi- 

 mental. — E. N. D. Nov. 22. 1834. 



E. N. D. obligingly supplied these definitions in reply to 

 the same point of question of our correspondent E. Wilson, 

 junior, as is expressed in VII. 251., who sent, after the pub- 

 lication of that question, specimens to illustrate it, which we 

 submitted to E. N. D. His reply above answers the point of 

 question, Is the larva luminous ? affirmatively. 



The Larva of the Glowworm differs from the Perfect Insect 

 most materially in point of size, its body being much larger ; 

 besides, it is more elongated, more segmented, and possessed 

 of greater power of motion. Mr. Rennie, who has given a 

 figure of it in his Habits of Birds, p. 25, 26., found it at Dart- 

 ford in Kent, so early in 1830 as March 14.; but has not 

 stated whether it possessed a luminous appearance at that 

 period. — James Fennell. Temple, May, 1834.
