ANTHOCHARIS I. 



thickly dotted with black." (Mead, Psyche, II. 183, 1878.) The tubercles with- 

 out doubt are disposed in same way as in Gcnutia, in straight cross rows on 2-4, 

 in triangle after. Mr. Mead was of the opinion, when the above was written, 

 that this larva was Lanceolata. He says : " At different times during June, I 

 found, in the Yo Semite Valley, a few caterpillars which I feel certain are those 

 of A. Lanceolata." He describes their chrysalids as having " the long palpi 

 case bent around backward into a sickle shape," and this identifies the species. 

 No other Californian Anthocharis has that shape of the chrysalis, and 1 believe 

 the chrysalids of all except one very rare species are now known. Those bred 

 by Mr. Mead died during the winter, he informs me. 



Chrysalis. — Length about one inch; slender, the abdomen tapering to a 

 point, the head case surmounted by a long tapering process, which in all exam- 

 ples observed is much recurved ; on ventral side the thoracic segments form a 

 prominent rounded projection, compressed laterally and covered by the wing 

 cases; color brownish-yellow, immaculate. (Fig. x.) 



Lanceolata flies in the hills of Marin, Sonoma, and other Counties in north- 

 ern California. Mr. 0. T. Baron found it most abundant in Shasta County. He 

 also took examples near Summit, July 6, 1888, the elevation being 8000 feet. 

 At Bear Valley, altitude 4:000 feet, he took a female while ovipositing on Arabis 

 perfoliata. Mr. Baron tells me that ten years ago he took this species in Men- 

 docino County early in April, and in Shasta County, at elevation of only 3000 

 feet, at the end of June, and he believes it to be double-brooded. That is the 

 more probable, as several other of the Pacific species of this genus are known to 

 be double-brooded, as Hyantis, Aiisonides, and Meakirtii, Sara being the second 

 brood of the latter. The late Mr. H. K. Morrison brought examples of Lanceo- 

 lata from Nevada, and it has appeared in collections from Arizona, but I am 

 unable to give the localities in either region.
