Heteroptera True Bugs). — Only one species of known beneficial im- 
portance is noted. It is the small Triphleps insidio&us which punctures 
boll-worm eggs, hi other experiments not tabulated an occasional 
soldier-bug was caught usually Podisus spinosus. In some of the ex- 
periments an insect (Galacoris rapidus) which contributes much to what 
is popularly termed *• sharpshooter" damage was trapped in small num- 
bers. A probably injurious cotton insect which the planters often mis- 
took for the genuine Cotton Stumer (Dysdcrcus suturellus) is Melanocory- 
phus bicrucis. This insect was trapped by hundreds but subsequent 
stndy proved that fully DO per cent were males. 
Homoptera (Leaf-hoppers^ etc.). — Homtdotlisca coagulata was caught 
in great abundance. Subsequent study showed that about 90 per cent 
were males. 
In the three orders, Diptera, Xeuroptera, and Orthoptera, nothing 
worthy of consideration was captured except a tew specimens of the 
beneficial lace-wing tiies. 
Experiment 6. 
Arlington, Tex.. August .'7. — Lighted at 7 p. m. and placed between rows of cow- 
peas adjoining a cotton field. The rows of cowpeas were o t<> 8 feel apart ami had 
many Boll Worm moths flying about them feeding. The weather was warm ami 
pleasant, the nighl very dark. Being placed between the rows, a distance of only 
about 4 feel remained from which to attract the passing moths. For an hour the 
moths kept flying up and down the rows on either side of the lamp, fed freely, de- 
posited eggs, and paid no attention whatever to the Light. A volunteer pea vine 
w as near the center of the row having a tew branches extending \\ ell up projecting 
over the edge of the pan within 10 inches of the flaring light. Some fresh Mossoms 
upon them proved attractive, and a tew adventurous females visited them, sipped of
