ON THE GLOW-WORM AND ITS LARVA. 85 
pleasure in adding this fine species to the British list of occasional 
visitors, though Iam far from believing that this is really its 
first occurrence in our island. It very closely resembles the C. 
Europeus, and is almost sure to be confounded with that species 
by the casual observer. 
XV.—Some remarks on the common Glow-worm, Lampyris 
Noctiluca and its Larva. By V. R. Perxins. 
No one who has ever seen the Glow-worm emitting its brilliant

were they. As it was, I brought away with me a good many 
living specimens in my collecting bottle, but unfortunately on 
my way home I was obliged to remain for two or three days in 
London, and so for nearly a week did these poor Glow-worms 
remain in their prison, packed up among my luggage. When
