of dwellings. All observations serve to show that the attractino- of 
the moths to ordinary oil lights is an utterl}^ hopeless task. 
Brilliant arc lights are an attraction, however, and during the early 
part of August, at Paris, along the business street, within a space of 
four blocks, sometimes as man}^ as fort}" or fift}" of the moths could be 
counted near the lights. Saloons and fruit stands offered especial 
inducements, no doubt on account of the odors of fermenting fruit, etc. 
Professor Morgan^ mentions a similar instance: 
Last season, in collecting by an electric light on the university campus, under which 
the crab grass had been permitted to grow and go to seed, great numbers of a hght- 
colored moth were seen to be perched upon the heads and stems of the crab grass, 
from 20 to 50 feet from the arc light. Upon collecting a few they were found to be 
specimens of the bollworm moth. * * * During the entire evening not a single 
specimen was seen to fly up to the light, but all remained at some distance from it. 
Chittenden^ also states that during the latter part of September, 
1900, bollworm moths formed about 16 per cent of the total number 
of moths attracted to the electric street lights at AVashington, D. C 
We have had experiences similar to the one noted by Professor 
Morgan. During early September it was observed that the corn 
plants for a distance of 50 feet surrounding the lantern traps were well 
supplied with hiding moths the day after the traps had been in opera- 
tion, although hardl}" any moths had been caught in the trap itself. 
ATTKACTIOX BY POISONED, SWEETS. 
All attempts to trap the bollworm moths in this way have yielded 
absolutely negative results. During the latter part of the summer 
quite a number of experiments were tried with different combinations 
in varying proportions of New Orleans molasses, sorghum, vinegar, 
and beer; some of them poisoned by potassium cj^anide or cobalt, and 
others not. The solutions were placed in flat pans elevated on pedes- 
tals from li to 1^ feet high (see PL XXV, fig. 2). None of them 
attracted more_than an occasional stray moth, although they were 
placed in fields of corn and cowpeas where the moths were extremely 
abundant. 
At other times during August and September a number of water- 
melons were cut open in the fields and left to ferment and deca}'. At 
no time did these attract any bollworm moths, although the cotton 
moth Alalama (AJetia) argillacta was observed to feed on them to a 
slight extent. 
Experiments were also tried bv spraying the cowpea vines with a 
mixture of sorghum, vinegar, and beer poisoned with cobalt. This
