THE eggs, laid June 17th, were small, oval, and green, turning dirty white before hatching.
Three caterpillars hatched in six days, two dying almost immediately. The
remaining caterpillar was whitish, growing greener as it ate. It did not eat the shell,
but attacked the leaves immediately.
It had whitish lines between the segments, a fold of whitish skin behind the head, and a short whitish horn. The setae were
invisible to the naked eye and the horn nearly so. It was about three sixteenths of
an inch long.
It spun threads of silk as it crawled.
It ate evening primrose and
wild grape, and ate small round holes in the leaves. The first molt came in four days and the caterpillar was much more gaudy than before.
The dorsum was blue-green with whitish green subdorsal lines. The sides were yellow-green with black spiracles. The venter was blue-green and the legs and props yellow-green.
The head was small, round, bright green, and still had a fold of whitish skin behind it.
In this molt the larva ate from the sides of the leaves. The second molt came in nine days.
The dorsum was blue-green, the sides were yellow-green granulated with white, and the venter was blue-green. There was a greenish white dorsal line and greenish white subdorsals which had on each segment a bright yellow dot. The stigmata1 line was light green, but on the first two segments

it was yellow edged above with black.
The dorsum of the eleventh segment was
almost black running up to the short black horn. The spiracles were black with yellow centers, the last two being very large. There was a green spot on the stigmata1
line under each spiracle.
The head was green, small, and round.
There was a
whitish raised plate on the dorsum of the first segment. The third molt followed in seven days.
The head was leaf-green, with a black
band above the mouth-parts.
The dorsal plate was whitish green.
The dorsum
was dark velvety green with a light green dorsal line. On the eleventh segment the
dorsum was black, and the whole dorsum shaded into black towards the subdorsals. The subdorsals were broken, being made up of small light green dots between the segments and large red spots on all the segments except the first two. There was a yellow spot on the second. The sides were lighter than the dorsum and covered with white dots.
The spiracles were yellow with a black area around them. The stigma- tal line was yellow and broken - disappearing between the segments. The venter was the same color as the sides, but the white spots were smaller and were only just above the legs and props. The legs were shiny black and the props were black with red plantae.
The caudal horn was red at the base and black above. The anal plate
was green with a brown tip and lighter edge. There was a light mark like a Greek
phi [+I.
As the caterpillar grew larger the colors became paler and the subdorsal spots turned salmon pink.
The fourth molt came in five days and this time the caterpillar was greatly changed.
The body was black and shiny. The head was slightly bilobed and pinkish brown, with a black line over the mouth-parts. The analplate and props and dorsal plate were the same peculiar color as the head. There were large salmon pink spots edged below with white on every segment from three to eleven inclusive. The sides were dotted with yellow. The spiracles were large and white, turning pink the next day. The horn was bright-vermilion, granulated, and could be moved up and down.
The legs were shiny black and the props were black with red plantae. In this stage the whole caterpillar looked artificial as if made of wax. It had
a peculiar habit of spinning a thread of silk as it brought its head up after eating a curve out of a leaf. t I-
It fed for ten days, growing to the length of three inches. Then it stopped eat- ing, grew shorter, the subdorsal spots turned purple and it crawled around very rapidly for a day. It then spun threads of silk to hold leaves together over it. Three days later (Aug. 1) it pupated, having had a larval life of thirty-eight days. The pupa was about an inch and a quarter long and very slender. The head,
and the antenna-, leg-, tongue-, and wing-cases, also the back of the thorax were

black, mottled with blackish yellow.
The abdominal segments were orange-yellow, with small black spots. The head was prominent and the cremaster was long. The moth is too well known to need description, as it is common, often flying in the daytime.
THE ARACHNIDA OF THE GALAPAGOS ISLANDS.
BY KARL R. COOLIDGE, PORTERVILLE, TULARE CO., CALIF., THE collection of Arachnida made by the California Academy of Sciences's Galapagos Expedition in 1905-06, which is now in my hands, numbers one hun- dred and thirty-three specimens, not including the Scorpionida and the Acarh, which I have not yet seen. But seventeen of the forty-one species of Araneida re- corded from the Islands are represented, and the Phrynida, Pseudoscorpionida and Solpugida include a single species each. Apparently none of the species warrant description as new, although the identity of the false-scorpion is somewhat doubtful. The present collection is the second largest ever made on the Galapagos archi- pelago. The first collection of importance was made by the Petrel Expedition in 1875. Seven species were enumerated by Butler in his report of this collection (Proc. Zool. Soc. London, 1877). In 1887-88 the Albatross visited the Galapagos, and Marx (Proc. U. S. National Museum, vol. XII, 1889) reports ten species, three of which Butler had previously recorded. By far the largest and most complete
collection was made by the Stanford-Hopkins Expedition in 1898-99, the results of which included about six hundred and fifty Arachnids. Bank's report on these was published in the Proceedings of the Washington Academy of Science, vol. IV, 1902. Prof. V. L. Kellogg also published a briefer abstract of the entomological and arach- nological collections in PSCHYE, vol. 9, p. 173, 1901. Perhaps the most interesting feature of the present collection is the series of Solpugids, Amrnotrecha solitaria Banks, obtained, sixteen in number, from five different islands, Charles, Indefatigable, Chatham, Abington, and Wenman. Hitherto, A. solitaria has only been known from a single specimen, the type, from Iguana Cove, Albemarle Island. Banks, the author of solitaria, remarks, "the presence of a Solpugid is unexpected, and it must have been a rare accident that stranded one of these animals so far from the main- land." But the fact that it is now known from six of the islands would indicate that it is not an introduced, but an endemic, species. The Academy's expedition also made small collections in Arachnida on Cocos Island and in Lower California.
