Mr. Samuel H. Scudder has prepared?” a table for the determination 
of the genera of North American Melanopli, and gives notes on the dis- 
tribution of species. 
Part V of the Bibliography of American Entomology prepared by 
the U. S. Division of Entomology has recently been issued. It con- 
tains 1679 entries. We are glad to note that Dr. Howard expresses 
his intention to bring the work down to date, and to continue it here- 
after. It is extremely serviceable to all working entomolugists. 
At a meeting of the Birmingham Entomological Society?! Mr. W. 
Wilkinson exhibited a collection of insects made in the Madeira and 
Canary Islands in February, March and April, 1896. Among the 
most interesting species were Pararge xiphia from Madeira and P. 
xiphiodes from Grand Canary, two closely allied but distinct species 
peculiar to the Madeiras and Canaries respectively. Mr. Kenricks 
said that the most curious feature in the Canary Island fauna was the 
occurrence of American forms. Vanessa huntera occurs only in the 
Canaries and America, and Anosia plexippus (=Danais archippus) 
which is common in the Canaries is also an American species. Mr. 
Bethune Baker said that in working on the moths he noticed American 
affinities in several groups, especially in the genus Phlogophora, which 
wes much more closely allied to American than to European forms.

Mr. Spencer’s Psychology.—The following letter by Professor 
J. Mark Baldwin, President of the American Psychological Associa- 
tion, was read before the Philosophical Club of Bryn Mawr College, on 
the occasion of the celebration of the completion of Mr. Spencer’s 
“Synthetic Philosophy.” 
To the Club: 
In speaking briefly of Mr. Spencer’s psychology, perhaps I can do no 
better than throw the impressions which I have into the form of infor- 
mal pros and cons. I should premise what I have to say, however, 
with the remark that one of my reasons for not accepting your kind
