52 THE CANADIAN ENTOMOLOGIST. 



5. Papilio Orego?iia. 



Until recently this species was known only in east Washington and 

 Oregon ; but the late W. S. Foster, two years ago, took a fine example at 

 Park City, Utah. Mr. B. Neumoegen has sent me for inspection a male 

 taken somewhere in Utah. And, in 1S91, Mr. Bruce found several 

 examples in west Colorado. It is evidently a desert species, ranging 

 from Washington to Arizona. In 1890, I had larvae sent me from east 

 Washington, believed to be of Oregonia. But, as they were found on the 

 plants, the sender could not be certain. I saw all the stages from second 

 to adult larva, and obtained one pupa. Of the last two larval stages, 

 I have drawings made under the supervision of Prof. Riley. The larval 

 markings and colours were unlike any Papilio larvse I have known, and I 

 think the species is certainly Oregonia; it can be nothing else, coming 

 from that locality. But, as the pupa died before imago, I could not figure 

 these stages on a plate as Oregonia. Now, I hope to obtain eggs and 

 begin from that stage, and so get the set of drawings for publication. 



6. Anthoc/iaris Sara and A. Reakirtii. 



On March 31st, 1888, I received eggs and larvae (hatched on the 

 way) of Reakirtii, laid 22nd inst. One larva passed first moult, 2nd 

 April ; second moult, 4th ; fourth moult, 8th April, and pupated on 13th 

 This pupa gave a true Reakirtii iniago the next year, 12th April, 1889. 



On June 4th, 1888, forty-three eggs laid by Sara, in confinement, 

 were sent me by Mr. A. Koebele, but the plant with them rotted, and not 

 more than two larvae reached me alive on nth. Mr. Koebele wrote that 

 Sara, of May and June, proceeds from eggs laid by Reakirtii in March ; 

 but that some pupae went over the winter to produce Reakirtii in the 

 early spring ; also that the product of Sara was Reakirtii of the next 

 spring. The dimorphism is as that of Papilio Ajax. 



It is very common for pup^e of Anthocharis to go over two winters 

 Mr. Koebele wrote me, in 1888, that he then had pupje of Sara and 

 Cethura that formed in 1886, and one of the first named he sent rfie, 

 labelled May, 1886. This, soon after I got it, gave imago Reakirtii. I 

 have a living pupa now of Genutia of 1890, the only instance I have 

 known in that species. A. Auso/ioides passes two years in pupa some- 

 times. Both P. Riitulus and P. Daitnus sometimes pass two years in 

 pupa.
