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.

In the December number, 1900, of this journal, page 369, the writer published the life-history of the above Arctian. During the past summer, through the kindness of Mr. A. Kwiat, of Chicago, in forwarding eggs of A. phalerata (laid 18th June), I have had the opportunity of still further studying this species, and, as these larvæ varied considerably fromthose described in 1900, the following notes were made :In the larval stages i, ii and iii those bred in 1901 answered well to my former descriptions. In stage iv the larvæ were not so black as the specimens reared the previous year, but many of them showed the dorsal stripe. This stripe was also present in stage v, besides which 40 of the larvæ possessed a series of pale orange spots on sides between tubercles ii and iii, and iii and iv, and the skin of the body in a line with the upper spots(between tubercles ii and iii) was slightly grayish, not black like the rest of the skin; this and the spots gave the appearance of a faint lateral band, distinguishable on all segments but 2 and 13. In stage v in 1900 none of the larvæ showed the dorsal stripe.

Found feeding on a wild cherry, September 19, 1884, two larvæ of this species. They were .80 of an inch long, nearly cylindrical, the body somewhat elevated in the middle, from which it tapers a little both ways, the dorsum of joint 12 with a slight elevation; eight low tubercles on each joint, from each of which arise a few spreading white hairs. Color green; a dorsal stripe that is mostly red on joints 3 and 4, and on the elevated portion of joint 12, the rest of the stripe yellow with a reddish, blotch to each joint; the anterior part of dorsum of joint 2 red, separated by green in the middle, yellowish round the edges. Head slightly bilobed; the lower part reddish green, the upper part more red.

Photographic Records

As part of a comparison of the collembolan fauna in soil of forest, grasslands and broadacre agriculture in north east Iran, several pale green specimens were found that complied with all characters of Isotomurus prasinus (Reuter, 1891) and keyed out as such in Potapov (2001) except that the body covering consisted of smooth mesochaetae and not ciliated chaetae as are present in prasinus according to Potapov (2001). On a more extensive examination of the recent literature, it was clear that the Iranian specimens belonged to the species Isotomurus graminis Fjellberg, 2007 described six years later. In his description, Fjellberg (2007) notes that some specimens of the new species could have previously been identified as I. prasinus in spite of having a different chaetotaxic covering. He also notes that, in a number of characters, it is identical with Isotomurus unifasciatus (Börner, 1901) but the colour differentiates them as this latter species usually has a broad, pigmented, longitudinal dorsal stripe.

Eight transverse wrinkles to each joint; green studded with pale green points; a subdorsal pale line, as usual converging to caudal horn; on sides, oblique pale lines that nearly coincide with a series on the dorusm; the plae parts yellowish green; caudal horn reddish tinted; head with a pale stripe on each side of face, the two coming together above.

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.

The Many

Abstract Comprehensive accounts of resource-rational attempts to maximise utility shouldn't ignore the demands of constructing utility representations. This can be onerous when, as in humans, there are many rewarding modalities. Another thing best not ignored is the processing demands of making functional activity out of the many degrees of freedom of a body. The target article is almost silent on both.

The simplicity of the developing nervous system of oligochaetes makes of it an excellent model for the study of the relationships between glia and neurons. In the present communication we describe the relationships between glia and neurons in the early periods of post-embryonic development in some species of oligochaetes.Tubifex tubifex (Mull. ) and Octolasium complanatum (Dugès) specimens starting from 0. 3 mm of body length were collected from laboratory cultures divided into three groups each group fixed separately by one of the following methods: (a) 4% glutaraldehyde and 1% acrolein fixation followed by osmium tetroxide, (b) TAPO technique, (c) ruthenium red method.Our observations concern the early period of the postembryonic development of the nervous system in oligochaetes. During this period neurons occupy fixed positions in the body the only observable change being the increase in volume of their perikaryons. Perikaryons of glial cells were located at some distance from neurons. Long cytoplasmic processes of glial cells tended to approach the neurons. The superimposed contours of glial cell processes designed from electron micrographs, taken at the same magnification, typical for five successive growth stages of the nervous system of Octolasium complanatum are shown in Fig. 1. Neuron is designed symbolically to facilitate the understanding of the kinetics of the growth process.
