never take each other for foreigners. In fact, in a long series of specimens 

 from either locality you might pick out "types" of either form, and besides 

 find a couple of "new'-' species. The value and necessity of western local 

 lists is thus shown. The sooner we know better the range, etc., of some 

 of these doubtful species, the sooner we shall be able to place them 

 correctly in our catalogues. The following list is, I think, quite complete, 

 except in the Hesperidce, to which I hope to make numerous additions, 



I am deeply indebted for various notes and favours to Mr. J. G. 

 Grundel, of Alma ; Mr. F. X. Williams, of San Francisco ; Mr. Fordyce 

 Grinnell, jr., of Pasadena, and Mr. E. J. Newcomer, of Palo Alto. 



Papilionid^. 



PapHio eurymedon, Boisd. — The commonest of the genus here, flying 

 from April to July. The food-plant is Rhammis californiciis. 



Papilio 7'tcttilus^ Boisd. — Not as abundant as eurymedoii. The usual 

 food-plant is Salix, but also Riibus and Magnolia. May to September, 



Pafilio zolicaon, Boisd. — Fairly common from May to November. 

 The larva feeds on UmbeUiferce, particularly Foeniciihim vulgaris. 



Papilio polyxenes., Fab. — Probably the variety aste?'oides, Reakirt. I 

 have not seen it, but it is reported to be common at Santa Clara. The 

 larval food-plant is probably Daucus carota. 



Laertias phile?t07', Linn. — Rare. It has been takenin February and 

 September. The larva, as in the east, feeds on the Dutchman's Pipe 

 ( Aristolchia s€rpefita?-ia), which is very rare in this county. 



PlERID^. 



Pontia occidentalism Reak. — Common everywhere in the valley. The 

 variety calyce, Edw., is the cold- weather form. 



Po?itia protodice, Boisd. — Rare. Protodice is the southern represen- 

 tative oi occidefitalis, and this is about th^ northern limit of its range. The 

 variety vernalis^ Edw., is the cold-weather form, appearing in late winter 

 and spring. 



Pontia jiapi, Linn. — The varieties venosa, Scudder, and castor ia, 

 Reakirt, are not rare in the lower foothills, where their food-plant grows. 



Pontia rapce^ Linn, — Superabundant everywhere, except in the higher 

 mountains, where it is rarely met with. 



Eiichloe ausonides, Boisd. — One of our earliest species, appearing 

 sometimes as early as February. The life-history was described in the 

 May "Entomological News" by Mr. E. J. Newcomer and myself 



Enchloe sara, Boisd., and Reakirtii, Edw. — xA.lso common and early. 

 Reakirtii is the spring and sara the summer form. The larval habits are 

 much similar to those of auso7iides.
