Spkrry During May of this year the authors collected a number of larvae belonging to two species of Melitaea, which were feeding on paint brush (CastiUcia lanata Gray). These were secured in a region known as Peppersauce Can- yon, situated in the foothills of Lemmon Mountain, near Oracle, Arizona. A series of these larvae were l^red to maturity resulting in the following notes: Melitaea theona f. bollii Edw. Mature Larva. Length, 25 to 28 mm. Head bilobed, bright yellow brown or orange, with a sparse covering of single long black hairs. Ocelli black on a black base which is slightly protruded. Mouth parts black, the clypeus flesh colored in its center. Basal segment of antenna flesh colored, with the tip black. First segment fleshy yellow, crowned dorsally with a series of black nodules bearing black hairs which curve forward. Lateral to this crest are three small black points, and inferior to the latter are two black spines. The body bears the usual series of branching spines which are characteristic of the genus. These are all glistening jet black. The body color of the upper half of the larva is a velvety brownish black with a purplish cast. Sprinkled over the surface of this area are numerous lens- shaped pearly white dots. These are, however, missing in the mid- dorsal area, which gives the appearance of a black mid-dorsal line, edged with a concentration of the white dots aforementioned. The segmental junctures are purplish and shining, in con- trast to the velvety texture of the PLATE 42 Lateral view of larva of Melitaea theona hoUii. enlarged x 3. Photo by Menke 99.
