after her, with a queer appearance of anger; gets in front, 
and stands facing her again; then she turns coyly round; 
but he, quicker and more active, scuttles round too, and 
seems to whip her with his antenne; then for a bit they 
stand face to face, play with their antenne, and seem to bé 
allin all to one another.” (“ Monograph,” p. 109.) It may 
seem to some readers that this has but little to do with 
mangold wurzel and mangold wurzel beetles, but I trust the 
departure from the strict order of science may be forgiven.—

E. De Brath.—Name of a Beetle-—The beetle is Crypto- 
cephalus _sericeus. Very common in yellow composite 
flowers throughout the summer.—Edward Newman. | 
S. L. Mosley— Diptera.—I1 shall be very glad to name 
any British specimens of Sarcophaga; of any belonging to 
the restricted family, Muscide; and of Anthomyide. There 
is no complete published list of British Diptera; but Mr. G. 
H. Verrall is at present engaged in drawing one up.—R. H. 
Meade; Bradford, Yorkshire. 
John Sterry, J, D.S., George Mennell, William Ashby, 
and a number of other Correspondents.—Fireflies—From 
various parts of the country 1 have received accounts of 
specimens of fireflies captured on the wing, and actually in 
the act of emitting light. The localities are chiefly—Keston 
Common, in Kent; Tunbridge Wells; Sandown and Bon- 
church, in the Isle of Wight; Fordingbridge, near Salisbury ; 
and Penzance, in Cornwall. A very careful examination 
and comparison do not reveal any difference in character 
between these and the males of the ordinary English glow- 
worm. ‘The prothorax has an indistinct, ochreous mark just 
within the margin, and without any decided limits beneath ; 
the legs have also pale longitudinal markings, and the 
terminal joint of the abdomen is yellow, more especially two 
circular spots, from which the light is said to emanate; the 
elytra have three longitudinal keels, which are very feebly 
pronounced ; and the wings are smoke-coloured. The speci- 
mens examined are from Keston Common and Penzance.—

runs over. We have taken them ten inches long. We should
