NOTES. 



LUMINOUS WORMS. 



Driving from Hudson to Corao on the 23rd of September, 1892, about 

 8 p.m., the night being warm and damp, I was much surprised to see on 

 the hard road something luminous, emitting quite as strong a light as the 

 glow-worm in England. We stopped quickly, but before I could get back 

 the few yards it had disappeared. Some half mile further we passed 

 another, which also, before I could get to it, disappeared. Can any of 

 your readers say what these were ? Their sudden disappearance and our 

 failing to find them, though we struck a match in both cases, would lead 

 me to think they were some sort of earth worm, as these draw themselves 

 quickly into their holes when disturbed. How else is their sudden 

 disappearance to be accounted for ? Lachlan Gibb. 



The cells of Megachile, which I send, were found in rather a peculiar 

 place last September, being attached to the trimmings of a dress which 

 was inside a wooden chest placed on a gallery in Montreal.

CORRESPONDENCE. 



LARVOPHAGOUS CATERPILLARS. 



Sir : On reading in the issue of the Canadian Entomologist for 

 January of Larvophagous caterpillars of P. philenor, I was reminded of 

 an observation which I made last summer. I had at that time several 

 larvse of Da?iias archippus in a wire cage, and supplied them frequently 

 with milkweed leaves, which they devoured voraciously. On one occasion, 

 owing to a delay in getting leaves, their supply became exhausted, and 

 in a short time — not more than an hour or two, I should think — one of 

 them attacked another which was about to change to a chrysalis, and 

 began eating it. Some of the others joined, and by the time the leaves 

 were obtained fully half of the unfortunate caterpillar had disappeared. 

 They ate it very slowly, not being hungry enough to relish it, I suppose. 

 My brother tells me that he has seen a larva of P. asterias greedily 

 eating the chrysalis of one of its kind which was hung on a fence.
