THE PIPE VINE SWALLOWTAIL and its first cousin, the 

 HAIRY SWALLOWTAIL (P. hirsuta. Skin.) are to be found 

 in the Northern part of the state, being particularly plentiful in 

 the region North of the San Francisco Bay. They have been 

 occasionally reported from points as far south as San Diego. 

 The California form is the variety named by Skinner and dis- 

 tinguished by its shorter tails and hairy body. 



Most of the Southern California captures seem to be the 

 typical form and are probably introduced from the eastern states 

 on AristolocJiiac, which is occasionally used as a porch-shading 

 vine. 



BAIRD'S SWALLOWTAIL. (Papilio, bairdi, Edw.) 



Plate III, Fig. 1, male; Fig. 2, female. 



Syn. utaliensis, Stkr. 



BAIRD'S SWALLOWTAIL is an extremely rare capture in 

 California. It has been authentically reported only from the 

 central Sierras to the San Bernardino Mountains. July is its 

 favored month. The larvae feed on umbelliferous plants. 



THE ANISE SWALLOWTAIL. (Papiho zelicaon, Luc.) 

 Plate HI, Fig. 3, male ; Figs. 4 and 5, females. 

 Syn. solicaon, Bdv. 

 Syn. californica, Men. 

 Syn. coloro, Wright. 

 THE ANISE SWALLOWTAIL is common throughout the 

 state, specimens being taken from February to November. It is 

 most abundant in the lowlands about townsites where its favorite 

 foodplant (Carum kelloggii, wild anise) occurs. The larvae feed 

 on a wide variety of umbelliferous plants. They are alst) oc- 

 casionally found on Citrus, but have never become a serious pest 

 in the orange groves.
