. the 31 remaining cases. Of these 26 reports, 38 were unfavorable, 19 favorable, 
and 4 doubtful, concerning the success of the experiment. These doubtful cases 
are not to be looked upon as unfavorable, but more evidence is needed to transfer 
them to the list of favorable reports. These 19 out of 26 reports, or 75 per cent., 
were decidedly favorable. The experiments will be continued during the season 
of 1891.

BurrerrLies oF NortH AMERICA. Third Series—Part X. By W. H. Edwards, 
The last part of Mr. Edwards’s superb work has just come to hand. It is of 
exceptional beauty and interest. Special attention has been lately called to the 
American species of the genus Argynnis, by the publication of Mr. H. J. Elwes’s 
“Revision of the genus Argynnis.” (Trans. Ent. Soc. Lond. 1889. Part IV.) 
and Mr. Edwards’s “ Notes” thereon (Can. Ent. XII. p. 82.) The present number 
contains plates and descriptions of three species of this genus, the validity of 
two of which has been questioned by Mr. Elwes. Plate I. illustrates the com- 
plete life history of A. Alcestis by which it is shown that not only is it distinct 
in the imago state from both Aphrodite and Cipris but also in its preparatory 
stages. 
Plate Il. Argynnis Adiante (male and female). This is a local Californian 
species of which Mr. Elwes had only male specimens taken many years ago—from 
what material he had hewas inclined to regard it as merely avariety of either Zerene 
or Monticola. It appears, however, that it is not such a rare species as he 
supposed, and Mr. Edwards had ample material to show that this species is valid. 
The male is figured from’ Dr. Boisduval’s actual type. Dr. Behr, the well-known 
San Francisco lepidopterist, writes of it that it is common in its season at the 
proper locality, and further that unlike many Californian Argynnides it is very 
constant. On the same plate as A. Adiante is figured another interesting species A. 
Atossa (n. sp.) the male of which has been in Mr. Edwards’s collection for twenty 
years ; but the female was only discovered in 1889. From the figure it appears 
to be very distinct from anything we have in our fauna. 
Plate III. shows Satyrodes Canthus in great detail. The text of this plate 
is very complete. Mr. Edwards has adopted Mr. Scudder’s genus for this species 
but believes the name Lwrydice does not belong to it.—J. F. 
THE Cave Fauna oF Norra AMERICA, with remarks on the Anatomy of the 
Brain and Origin of the Blind Species. By A.S. Packard, M.D. Vol. IV.: 
First Memoir—National Academy of Sciences. 4to., pp. 156. 
The author of this admirable volume is everywhere known throughout the 
scientific world from his numerous works, especially on entomology, and has 
. . . . + . dr +t 
obtained a deservedly high reputation in Europe as well as in America. This 
reputation will, we are confident, be, if possible, enhanced by the elaborate mono- 
graph before us. It contains many original observations of cave animals, some 
careful scientific investigations, and a very interesting chapter of philosopuic
