Dr. Behr made some remarks upon the Lepidoptera and the four 

 different stages of their development, noticing the fact that the 

 length of time of the egg state in some species, for instance the Chi- 

 nese silkworm, admits of the transportation of the same to foreign 

 countries, while in the Californian silkworm, Saturnia ceanothi, the 

 period of the egg state is so brief as to render it impossible to trans- 

 port the eggs either to New York or Europe. Dr. Behr also ex- 

 plained the difference between the larva state in the Lepidoptera 

 and other classes of insects, and referred to the importance of the 

 larva condition in insects as a basis for classification, and mentioned 

 many interesting proofs of the tenacity of life during the chrysalis 

 or pupa state; alluding to the different classes of moths in which 

 wingless females occur, a peculiarity that is unknown to the butter- 

 flies.

 current volume, (p. 225) he had referred a small pine growing 

 on the plains between Mendocino City and Noyo, to Pinus mur- 

 cata ; but he could now state positively that it is the true Pinus 

 contorta of Douglas. He stated also, that No. 7, noticed on page 

 227 of that article, is P. muricata. Farther, on page 229, 

 Quercus Wislizeni, Englm. is wrongfully referred to Q. agrifolia. 

 Q. Wislizeni is a well characterized species- with biennial fruit; the 

 fruit of Q. agrifolia, on the other hand, is annual. These two oaks 

 differ also materially in their distribution. Q. Wislizeni is found
