320 REPORT 4, UNITED STATES ENTOMOLOGICAL COMMISSION. 
catcli-wing, B, against which, or against a lantern face itself, one or the other, the 
moth, attracted by the lantern and lured as well by an odorous bait below, precipi- 
tated itself according to its habit of flying to or of passing close alongside of a bril- 
liant object ; a cover, C, projecting well over all, prevents upward escape even if else- 
wise possible to its now violently arrested flight, and all below lies a trap-basin, D, 
charged to a suitable depth with the common enticing bait, and effectual death-bath 
as well, of sweetened water and vinegar, poisoned with cobalt. Centrally up from 
the basin's bottom rises a conical socket to cap securely on to a stake so planted firmly 
afield as to hold the exterminator jnst sightable above the general surface of the crop 
foliage. 
" The opal panes may be advantageously tinged with a trace of pink, to better simu- 
late the color of the young cotton bloom ; the catch-wings, the under side of the cover, 
and the inside of the basin are to be of cotton-leaf green, and all other visible parts a 
quiet earth color; the lanterns are to be of such size and so disposed that one may be 
readily sighted and sought from any directiou within the field or approachiug it. The 
exterminator is to remain baited and posted day aud night, the lamp to be lighted 
as quietly as possible before twilight, and charged to surely burn the whole night 
through ; its use to begin before the first moth of the season may be reasonably ex- 
pected, and to continue till the last-belated straggler is surely gone. Operations, 
however thorough, confined to a limited area, unless absolutely secluded, can give 
only partial relief. 
"To secure specimens of other ' lly-by-nights/ fit a wire-gauze floor a little below 
the rim of the basin, and place beneath it a sponge saturated with chloroform." (J. 
Stith. ) (Dept. of Agr. Report on Cotton Insects, 1879.) 
u The Pugh Lamp. — Another somewhat more complicated contrivance 
of this class is that invented by Mr. Edward D. Pugh, of Fort Plain, Iowa 
(patent No. 130390, August 13, 1872). Plate LXI, Fig. 5, shows that 
it consists of the usual shallow pan, A, wherein is placed a rectangular 
case, 13, made of gla*s and sheet-iron, with short feet attached to its 
bottom aud with a cover, c. The bottom is perforated for ventilation, 
and a lamp, D, is placed within the case. So far there is nothing par- 
ticular about this lamp, but it has, in addition, an arrangement to in- 
crease its attractiveness to the moths. Around the case is a frame, a a, 
with tubes, b fr, attached to the inside and aperture communicating with 
the outside. E represents a common long-necked bottle placed on one 
of the tubes, on the inside of the case. The number of the frames, A, 
and of the tubes may vary, but on each of them a bottle is placed con- 
taining honey and wax or other suitable bait that is attractive to 
moths, which are consequently not only attracted by the light, but by 
the smell of the baits, and are either killed by falling in the pan or by 
passing through the apertures into the bottles, from which they cannot 
escape. 
u The Garrett Lamp. — This was patented by Mr. James G. G. Garrett, of 
Port Gibson, Miss. (No. 133023), in November, 1872. The accompanying 
Plate [LX, Fig. 1] is a, side, view, partly in section, of tin 4 same. The let- 
ter A represents a stake driven into the ground, with a plank, B, nailed 
to the upper end. Upon this point is placed a sheet-iron pan, C, -about 
18 inches wide and 2 inches deep. In the center of the pan is a block 
or support, I), about 2 inches high, upon which is set an ordinary lan- 
tern, E, which is kept in place by being secured to the edges of the
