Scarabaeidae 
Amnhimallon na .jails (Eaz.), the European chafe? 
A mixture containing 15 percent of chlordane, 82.5 percent cf ethylene 
dichloride and 2.5 percent "Tween 20" diluted with water, 5 to 20 ml. per 
gallon per square yard of soil, gave from 12.2 to 21.9 percent control of 
third-instar larvae of the European chafer three weeks after treatment of 
the soil plots. — Gambrell and Mason ( 171 ) . 
Anomala oriental is '.faterh., the oriental "beetle 
Autoserica castanea (Arrow) , the Asiatic garden "beetle 
Practical control of the oriental beetle was obtained with chlordane 
at 5»^ and 10.8 pounds to the acre and a mixture of DDT at 13 pounds, an 
chlordane at 5»^ pounds to the acre. In another test a 50-percent chlor- 
dane powder, applied dry with a patented turf duster, in April, at a rate 
to give 10 pounds of toxicant to the acre on a mixed population, gave full 
control of the new generation, which consisted largely of oriental beetle 
larvae, by October.— Adams (£) . 
Conostethus impressua ( G-oldf . ) 
In laboratory tests 5-percent chlordane dust killed only 6.6 to l6.6 
percent of the beetles in 120 hours when applied at the rate of 0.22 mg./ 
sq. cm. (20 pounds per acre) . — Petty ( 363 ) . 
Cotinis nit Ida (L . ) , the green June beetle 
Chlordane at 3 1/2 pounds per acre, worked into the soil to a depth 
of 3 inches, killed 26.5 percent of the grubs and at 5 pounds per acre it 
killed 38.9 percent of the grubs. A 5-percent chlordane dust and chlor- 
dane spray were ineffective against the adults in laboratory tests. — Xy. 
Agr. Expt. Sta. (258). 
Cyclocephala boreal is Arrow, the northern masked chafer 
A 5-percent chlordane powder, applied to soil with a fertilizer 
spreader at rates of 5»*+ to 21.7 pounds toxicant per acre, virtuall;- elimi- 
nated all grubs on a golf course on Long Island. The chlordane was applied 
in May and observations made in October. — Adams (8). 
Popillia japonica Newm. , the Japanese beetle 
Chlordane is very effective against Japanese beetle larvae ts. 
The principal tests of chlordane against this beetle have been made in I 
Jersey by Fleming (122, ljjO) , in Connecticut by Schread (^ 05-410 ) . and in 
Maryland by Langford and Squires ( 284 ) . 
In laboratory tests of treated soil against third-instar larvae 1 
pound of chlordane per acre when freshly applied was as effective as
