of the muslin: oblong, equally rounded at both ends, white, 
glossy. The young larve began to appear on the twelfth 
day, June 16th, and attached themselves to the lower edge of 
the leaves, generally with the anterior part of the body curled 
in after the manner of the Ionic volute, and apparently moving 
only to bend down to feed.

The Plague of Locusts in America. By Epwarp NEWMAN. 
Tur Colorado potato-bug, although causing serious and 
perhaps not altogether groundless anxiety to our transatlantic 
cousins, has been a source of unalloyed pleasure and profit 
to ourselves. Doryphora 10-lineata, for so it is called, has 
brought more substantial sustenance to the penuy-a-liners of 
St. Giles’s and the Strand than Solanum tuberosum itself; 
more lasting fame to our natural-history scribes and wonder- 
mongers than the last new noyel on Evolution. The half- 
starved literary hack; the fashionable novelist; the mystical 
purveyors of the grand results of scientific research ; the 
slip-shod conversationist of society ;—have equal cause to 
fall on their knees and thank Providence for this inestimable 
boon. But while we are thus paying this just tribute to the 
fertility of American soil and imagination, we are forgetting 
that America herself is suffering under the direst insect- 
scourge that ever afflicted the human race,—a scourge that 
has brought disease, desolation, dearth, and death, into 
thousands of once happy homesteads. 
Until very lately we have rarely heard of locusts as one of 
the plagues of America. Egypt has long been celebrated as 
the mother and nurse of locusts, the seat and centre of locust 
devastation, whence the plague has spread east and west and 
south; the north only owes its immunity to the fact that the 
country is there bounded by the sea, which presents no 
harvest adapted to its requirings; and even northwards the 
locust has penetrated Turkey, Greece, Italy, France, and 
Spain, neither of which countries has enjoyed perfect 
immunity from the death-fraught visits.
