Head rather flat, as broad as first segment, gray striped with dark brown, and with a broad black band, ragged iu front, running up each side to top of lobe, but not continued over the summit.The dorsal stripe consists of a series of rounded, brown patches with a black central line; tubercles, although not large, tipped with white, and conspicuous; subdorsal stripes brown, interrupted and indistinct.

Some time ago Mr.Henry G. Willard, of Grinnell, Iowa, very kindly sent me of the full grown larvæ of this species. I made a few notes at the time which may be of use, owing to the fact that nothing has been publihsed in regard to the early stages of this butterfly. The food plant at the home of the insect is Rumex longifolius, but they readily ate our common species of dock found here. The full grown larva were onisciform in shape, grass greein in colour, and 20 mm in length. Most of them had a narrow, claret-coloured dorsal stripe, and the entire body, under a glass, was seen to be clothed with minute black hairs.

Zoœcia strongly pyriporiform, very small, length about ·4 mm.; areas broadly speaking elliptical but with a strong tendency to have the upper end flattened rather askew to the central line, average length ·18 mm., breadth ·11 mm.; the side walls of the area bear about a dozen tubercles so small that their existence is only just recognizable under a 3 in. objective; a 1 in. objective shows them to be perforated; below the area there is typically (after the early stages) a small perforated boss placed centrally on the front wall, but when the front wall has to accommodate an oœcium the boss splits into two, often very massive, one on either side of the oœcium.

The morphology of larva and pupa, as well as larval mines of Elachista zonulae (Sruoga, 1992) are described and illustrated for the first time. Carex firma Host is reported as a new host plant ofthe species; previously only Carex sempervirens Vill. was known to be host plant of E. zonulae. Some information on life history of this elachistid moth is also provided. The mature larva is 4.5—5.5 mm long. Pupation takes place usually at base of leaf blade of the food plant. The species is univoltine and hibernates as young larva.

Since the food plant and early stages of Graptaj-Album appear to be unknown, perhaps the following notes (incompletee as they are owing to my ignorance of the species larvæ I was rearing) may still be of some value of shed a little light on the early stages of this fine butterfly.

The eggs of this rare species were kindly sent me from Tacubaja, Mexico by Mr. O. W. Barrett. The food-plant of the caterpillar was unknown to him. Heretofore we have only had the figures of the mature larva of three species of this genus, and four sketches of the caterpillar of A. armida, the better known species of this interesting genus, which ranges from Mexico to Brazil. The larva figured by Madam Merian, Stoll, Burmeister, and by Peters, is represented as being smooth, without any tubercles, horns, or hairs.

This article presents characteristics of the habitats and flying period of Melitaea timandra Coutsis et Oorschot, 2014 and describes the behavior of the adults under natural conditions, their food plant, egg chorion morphology, and caterpillars of the first and senior instars. In addition, a larval parasitoid is identified as Cotesia sp., and the possible development cycle of M. timandra is described.

On the 22nd June, 1901, I received from Mr. A. Kwiat, of Chicago, a batch of eggs of Arctia virguncula, Kirby. These eggs were laid on the 18th June and hatched on the 25th and 26th. The following notes on the early stages of the species were taken. A brief description of the mature larva was published by Mr. Coquillett, in the first number of Papilio, in 1881.

Initial Deposition

Our understanding of the structure and the formation of inorganic minerals in the bivalve shells has been considerably advanced by the use of electron microscope. However, very little is known about the ultrastructure of valves in the larval stage of the oysters. The present study examines the developmental changes which occur between the time of conception to the early stages of Dissoconch in the Crassostrea virginica(Gmelin), focusing on the initial deposition of inorganic crystals by the oysters.The spawning was induced by elevating the temperature of the seawater where the adult oysters were conditioned. The eggs and sperm were collected separately, then immediately mixed for the fertilizations to occur. Fertilized animals were kept in the incubator where various stages of development were stopped and observed. The detailed analysis of the early stages of growth showed that CaCO3 crystals(aragonite), with orthorhombic crystal structure, are deposited as early as gastrula stage(Figuresla-b). The next stage in development, the prodissoconch, revealed that the crystal orientation is in the form of spherulites.
