known, two pairs of abdominal, as well as cephalothoracic, legs. 
He does not consider that they belong to the Arachnida, with 
which they have been hitherto placed, but that they are much 
more nearly allied to the Crustacea, from which they differ, of 
course, in breathing through trachez instead of gills. He be- 
lieves they must form a fifth class of Arthropods equivalent to 
Crustacea, Myriapoda, Arachnida and Hexapoda. 
CARRYING OUT THE LAaw.—The British Parliament passed, in 
1877, an act providing for the imposition of a fine for the person 
who should import living specimens of the Colorado potato-beetle. 
That this act did not remain an empty letter is proven by the fol- 
lowing case: In February of this year it came to the knowledge 
of the authorities that a man in Devonshire had in nis possession 
living specimens of the Doryphora, which he had brought over 
from America, and which he refused to give up. The man was 
immediately tried, convicted and fined 45, notwithstanding he 
proved that he had meanwhile killed the beetles. The Devon- 
shire farmers are said to be much dissatisfied at the small amount 
of the fine, the maximum penalty fixed by law being 410. 
Locusts 1v Mexico 1x 1880—We are indebted to Dr. E. 
Palmer, for the following data concerning the appearances of 
locusts of unknown species in Mexico last autumn. They appeared 
during October at Chihuahua, at Saltillo and at Parras. At Saltillo 
they attacked the winter wheat, which was sufficiently advanced 
‘to be injured by them.—A. S. Packard, Fr. 
Erratum.—A rather annoying error crept into the article on 
Cicada in the last.number. On page 481, line fourteen, from 
bottom, “1860” should be “ 1660,” that being the year of the 
last simultaneous appearance of the two broods that appear this 
year. ;
