on the 15th of June 1869, I obtained several Thecla larvæ by beating over an umbrella the branches of some small oak trees growing in a cemetery about two miles west of London. Not having met with them before I at once took the follorving description : Length, ·40 in., onisciform. Head small, pale greenish-yellow with a minute black dot on each side. Mandibles pale brown, with a faint whitish patch immediately above them. Body above yellowish-green, streaked above with yellowish-white, and thickly covered with fine, short, white hairs ; second segment of rather a darker shade of green than the rest of the body.

On the 6th of June 1903, we found a Thecla caterpillar unknown to us feeding openly upon the berries of Vaccinium corymbosum. Its general colour was bright yellowish-green, which served to render it comparatively inconspicuous while feeding in the midst of a cluster of the unripe fruit. A faint, draker, dorsal stripe and a very minute coral-red spot in the middle of each segment, just above the lateral fold, were the only markings. The head was of a uniform light brown, and the body was clothed with short pile. Length, 12 mm.

Length .50 of an inch, elliptical, as is the usual shape of the Lymacodes group, nearly .20 of an inch high and about the same width. The dorsum has four lines of purplish black alternating with white, and bordered outside with yellowish white or pale yellow. The region of the subdorsal line is a bright vermillion ridge with yelrowish white tubercles arising from joints 2, 3, 4, 7, 10 and 12, those on joint 2 moderately short, but those on joints 4 to 12 are nearly one fourth of an inch long; all of them spiny. There are short bunches of spines on the intervening joints, as it were representatives of missing tubercles. In the subdorsal space are four scarlet lines alternating with lines of yellowish white, the middle yellowish line instead of being continuous, consists of alternate blotches of vermilion and yellowish white. The substigmatar line is vermilion, bordered as the subdorsai with pale yellow, and this also has its row of yellowish white spiny tubercles, each about one sixteenth of an inch long. Below this is a single dark purple line bordered each side with a lighter shade, and below this a vermilion line or rather a series of tubercles without spines in place of the prolegs. Legs 6, no prolegs, but the under side of the body consisting of a muscular pad upon which the insect glides along instead of walking. Head brown, retractile when at rest into the joint back of it.

Body Column

A new vital marking procedure was devised, studied, and applied to the phenomenon of hydra column tissue movements. The method involves injecting colloidal carbon (India ink) into the ectodermal epithelium of hydra. The carbon is taken up specifically by epithelial cells and packed into lysosome residual bodies. Each marked cell is then identifiable by its aggregated carbon particle, which appears as a black dot; this is passed to a daughter cell during cell division. Using this method to stain vitally the ectoderm of the green hydra, Chlorohydra viridissima, whose endodermal cells were marked by symbiotic algae, the relative movements of ectoderm and endoderm along the body column were analysed. Ectoderm and endoderm move in different directions or at different rates in the top quarter of the gastric column, but move together in the lower part of the column. This indicates that some epithelial cell movements involve cells migrating relative to the mesoglea; other movements involve translocation of the entire body wall, including ectoderm, mesoglea and endoderm.

Solution Changes

Action of Acids on Chlorophyll . Every one who has worked with chlorophyll must he familiar with the peculiar effect produced on the addition of acids to its solutions. If an alcoholic solution be taken, the colour of the solution changes when an acid is added from bright green to yellowish-green, and the spectrum at the same time undergoes alteration. After standing some time the solution gives a dark green deposit, which, after separation from the greenish-yellow liquid, shows when dissolved in boiling alcohol or ether, the spectrum of so-called “acid chlorophyll.”
