. Bulletin of the Southern California Academy of Sciences. Science; Natural history; Natural history. There is some variation in the markings of the mature larvae. In certain examples the areas of w^hite are considerably reduced. One example showed a ground color of light olive green, but no specimens in the series of forty under observation showed the grass green that occurred in a minority during the third instar. Pupation occurred under ground, the larvae burying them- selves as deep in the ground as our breeding cages would allow. Mature larva illustrated on Plate 31. Pupa. Length, 30 mm.

Pupation occurred under ground, the larvae burying them- selves as deep in the ground as our breeding cages would allow. Mature larva illustrated on Plate 31. Pupa. Length, 30 mm. Greatest width, mm. Color, uniform chestnut, slightly darker on last two caudal segments. Cylindrical, robust, gently rounded at the cephalic end, and tapering evenly on the last five abdominal segments to the jxjinted cremaster. The thoracic and cephalic areas are smooth and glistening, as are also the wing cases. The abdominal segments are pitted along their anterior margins, and the last three caudal segments are pitted over most of their surfaces. The cremaster terminates in a long tapering spine which is bifurcated at the tip. There are two short spurs at its base. Spiracles, dark brown. No setae are present on any portion of the pupa. Plate ?)2 illustrates three aspects of the pupa with sufficient clarity to obviate the necessity of further description. Arcfonotus hicidiis is single brooded, and an early flyer be- ing on the wing from late January to ABC PLATE 32 Pupa of Arctonotus lucidus. enlarged approx. x 2. Dorsal aspect. B. Ventral aspect. C.
