6r. Anthocharis creusa Db. & Hew. Found with P. sisymbri, but 

 rarer. 



62. Anthocharis sara Bdv. i male taken in 1903. 



63. Colias eurytheme Bdv. Common and at all elevations. The al- 

 bino females plentiful. 



64. Colias chrysomelas Hy. Edw. Rather rare, especially so in 1907. 

 In the valley and canons in July. 



65. Parnassius clodius, Men. A common insect at proper elevations. 

 In the mountains in July. 



66. Parnassius smintheus var. hennodur Hy. Edw. Perhaps rarer 

 than the preceding, with which it flies in the Canadian Zone. 



67. Papilio pliilenor Linn. None taken, but several old specimens ob- 

 served about Castella. Not rare in lower Shasta County on the flowers 

 of buckeye (Aesculus californica). 



68. Papilio zolicaon Bdv. Rather common, except in 1907. Both red 

 and yellow banded larvae of this species were noticed. Found most 

 commonly on mountain summits. Shasta specimens appear finer than 

 those from the San Francisco bay region. 



69. Papilio indra Reak. A rare and rather early insect, taken on 

 the Sacramento and McCloud Rivers. There is some variation in the 

 length of the tails in this Papilio. 



70. Papilio eurymedon Bdv. A common insect in the valley and on 

 the mountains. The larva of this species was found feeding on Rham- 

 nns californica and two species of Ccanothus. The larva of this and 

 of the following two species, when about to pupate, change from green 

 to chocolate-brown. Eurymedon pupae may be brown or greenish in 

 color. A female reared from a larva emerged April 29, 1908. 



71. Papilio rutulus Bdv. Commoner than the preceding species and 

 usually restricted to the valley region. On a moist sandy spot on the 

 banks of the McCloud River, Papilio rutulus and eurymedon congre- 

 gated in numbers, in company with numerous M. chalcedon, L. piasus 

 and others. A single stroke of the net bagged a number of the swal- 

 lowtails. The imperfect specimens were killed and arranged on the 

 sand and boulders with the effect of attracting other Papilios, flying 

 downstream. These, pausing to view their slaughtered brethren, were 

 readily captured, and thus a fine series of perfect specimens, all males, 

 were taken. 



72. Papilio daunus Bdv. This fine insect was found to be rather soli- 

 tary in its habits and difficult to capture, especially in first-class condi- 

 tion. It is partially double-brooded, the spring adults appearing in 

 May and June, and the summer ones in late July and early August. At 

 the end of June both young and mature larvae of daunus were ob- 

 served feeding on Cerasus demissa. Several imagines were reared 

 from these larvae and emerged in early August, while other pupae 

 hibernated. The larva is much larger than that of eurymedon, being
