This rare little blue occurs on the Mojave Desert in locali- ties where its foodplant. Oxythcca perfoUata T. and G. is abun- dant. It has been taken plentifully on the Randsburg road about 20 miles east of the town of Mojave during the months of April and May. Captures are also recorded for the upper Mint Canyon region, the lower Mojave near Victorville, and the "Box S" Ranch, San Bernardino County. The egg was described in the , 1930, number of the Bulletin Southern Calif. Academy of Sciences, Vol. XXIX, No. 1. The illustration there used is repeated on the accompanying Plate 25, fig. a. It is only necessary to add to the notes already published that the eggs are laid singly on the food plant, and hatch in 8 days. The plant of choice is Oxytheca perfol- iata, but as it is practically impossible to keep this fresh even with careful transplant- ing, a substitute was required to bring the larvae through to maturity. This was found in Chorisanthe calif or nica Gray. With both plants it was noted that the caterpillar fed only on the small fleshy points which arise from the stem around the leaf junctures. When at rest the larva curls around the stem at the site of feeding, and in this sit- uation it is difficult to distinguish on ac- count of its protective coloration. The young larva possesses a ground color of yellowish green, with a variable amount of rose. There is usually a mid- dorsal line of this rose or brownish rose color, and frequently a yellowish lateral line. A few examples show almost a solid rose or mauve, while others have the mid-dorsal line slightly shaded laterally with yellow. In all stages of growth there is wide vari- ation in the color pattern. Head, black, and retractile. As the larvae mature they tend to lose the rosy shade, and assume a darker green. A certain percentage are almost a solid green. Ma
