“The New Zealand Glow-worm.” Boletophila (Arachnocampa) luminosa. (Extract from the Annals and Magazine of Natural History. Ser. 9, vol. 17, p. 228, February 1926, and Ser. 9, vol. 18, p. 687, December 1926.) Mr. G. V. Hudson summarizes results of observations begun by him in January 1885 on New Zealand Glow-worms. He reared flies (both females) from the larvae in 1889 and 1890, description of the fly by Skuse, who named it Boletophila litminosa, appearing in Trans. N.Z. Inst., vol. 23, 1890, p. 47. The type-specimen was deposited in the Australian Museum, Sydney, the other being retained in Mr. Hudson's own collection. Another fly, again a female, was reared in September, 1926. Of this specimen, both the imago and pupal skin have been deposited in the British Museum. Details as regards the web spun by the larvae and the food captured by them were observed by Mr. A. Norris, a pupil of Mr. Hudson's, during the years 1892, 1893, and 1894, and a note sent by him to the Entomologists Monthly Magazine appeared in September 1894, p. 202. This note is as follows:— “I have observed the larvae in their natural haunts forming their webs, which consist of a kind of mucus, which is discharged from all parts of the body. If you take a larva from its web and put it on the ground, it will stay there until it has discharged enough of this mucus from which to slide out. Wherever it goes it leaves a mark in the same way as the snail. When the larva is making a fresh web, it raises its head and first four or five segments in the air, and reaches round about until it strikes something. It then draws its head back a little way, thus making a very flue thread of mucus. It then passes it to the thick mucus on the first segment, then slides out a little way, and makes another thread on the other side in the same way, fastening each to the thick mucus on the body. When it has made a sufficient number of these braces, it begins to make the strings of beads which hang downwards from these braces by gliding out of the braces, and lowering its head and about half the body. It then works its head and body up and down as if to vomit. You can see the mucus gathering on the body. Then it draws its head right back into the first two segments, as if it were turning inside out. It then catches hold of the mucus on the edge of the segment, and forces it forward. Now the head is out straight, with a large drop of mucus all round it like a drop of water. Then it draws its head gently out of the mucus, thus making a short fine thread from it. It then makes another drop, and another short thread; then a drop, and so on, until it has made several of these pendants of beads, which may vary in length. I have seen them from one inch to four or five inches. I believe in caves, where there is no wind, they reach the length of two feet. At night, when the larva is shining, you can see the reflection of the light for a considerable distance along the main thread or tube. When it is in a small
