Trap for Heterocera. Many devices for luring and trapping night flying 
lepidoptera have been tried, with more or less eed of success until most collec- 
tors look with suspicion on any but the orthodox modes of procedure. A mode 
communicated by a friend and said by him to have been successfully used is 
explained by the annexed diagram. ‘The arrangement consists of a lamp a, 
backed by a reflector if possible, and as intense as 
convenient, and throwing its light through a flaring 
box constructed of wood or other material, the 
diagram showing a vertical section. The sides flare 
equally with the top, and the bottom board is 
flared or not, according to the situation in which 
the apparatus is to be used: if used on a level 
eround and not far trom the surface, it should not 
be flared : in this box are arranged four panes of clear glass as thin as may be, 
slanted as shown in the figure, / and d reaching the top and ereaching the bottom. 
Close tothe lamp and beneath the last compartment formed by the glass is plac- 
ed ajar. b heayily charged with cyanide. Lhe machine acis as follows. It is 
placed in the woods or elsew here where the moths may be supposed to abound 
and the light shining through the flaring box which by the bye may be whitened 
inside, attracts all moths that can be so attracted : flying toward the source of 
attraction they first strike the glass f which slants inwardly beneath and does 
not reach the bottom ; the moth will fall to the base board and recovering will 
} ‘move forward striking the glass e, which inclines inwardly above and up this 
incline which should not be too steep, they fly to and through the aperture at the 
top stricking the glass d which again slants inwardly beneath and following this 
slant the moth will find the entrance beneath, and fly against the glass ¢ which 
covers the end of the flare and is nearest to the light ; the fumes of the cyanide 
from the jar } will almost immediately overcome the insect and it will drop into 
the jar placed for its reception. The advantage of this arrangement is that it can 
be placed outside anywhere and left to itself and it will act as long as the light 
lasts or the moths fly—it is not possible for an insect to find its way back and 
the way in is made very easy for it. The dotted line illustrates the probable 
course of the moth.

Fruit Insects: Mr. Wm. Saunders new book on insects injurious to fruits is 
at hand and is a volume well worth its price to all fruit growers. ‘I'he plan is to 
treat of all the insects affecting each fruit in one chapter, dividing them ac- 
cording to the part of the plant attacked, and giving the modes in which the 
ravages of each may be checked. Itis profusely illustrated, few of the drawings 
being original while all the old figures which have been used over and over again 
in text books and agricultural reports may be recognized. Mr. C. V. Riley’s well 
known drawings me largely represented as usual. Little original work has 
been done by Mr. Saunders for this book, and its value is as a compilation of 
what has been published heretofore in publications all over,the Country. We 
regret that it is confined to frnit insects alone.
