. Bulletin of the Southern California Academy of Sciences. Science; Natural history; Natural history. I'h in1 iiis melissa Edw. is one of the widely distributed blues of western North America, occurring from Kansas to tlie Pacific Coast, in spite of tliis extensive range and comparative abundance, almost Ing is known of the early stages. In the mountains of southern Cali- fornia, melissa is well represented by the race lotis Lint. An example of this race was observed in the act of ovipositing, and a. few specimens of the eggs secured for purposes of illustration. The single female under observation laid most of her eggs on small pebbles close to the base of a lupine, or on small leaves of the main stem near its juncture with the ground. Egg. Color, light green; shape, echinoid, the top flattened, micro- pyle depressed, the area around it slightly raised. The surface is cov- ered with a ret it illation of raised ridges which help to form depressed pits disposed in irregular pattern over all exposed surfaces. Where the ridges meet there are protruding points. The floor of each pit is finely perforated. Those pits which occur within the mocropyle are very minute, while those around the micropyle, though slightly larger, are of lesser size than on other surface areas. These pits grow pro- gressively larger as the outer surface is reached. s€Z/.. PLATE V. a, b—Egg of P. melissa, highly magnified, the upper cut representing a cross section. c.—Egg of Me!, neumoegeni, highly magnified. In Vol. 22 of the "Bulletin" p. (39, a number of notes were given concerning the early stages of Melitcea neumwgeni Skin. During March of this year we were fortunate enough to observe the ovipositing of this species, which thus completes the description of the life cycle, except for detailed observations of all the larval moults. Egg. Light green, exactly harmonizing with the foliage. Measures about V2 by % mm. Micropyle not depressed; finely pitted. Upper half of egg
