GLIRICIDIA SEPIUM (Jacq.) Steud. Madriado. 
This speoies was considered one of the insecticidal plants occurring 
in Nicaragua.— Roark (332 , p. 23). 
GLYDYRRHIZA GLABRA L. Common licorioe. Same as for Genista tinctoria . 
HAEMATOXYLON CA1SPECHIANUM L. Logwood. 
Two commercial extracts were effective repellents against the 
Japanese "beetle.-- Metager and Grant (277) . 
INDIGOFERA TINCTORIA L. Synonym: I_. indlca Lam. True indigo. 
In Jamaica this plant was employed to destroy vermin.— Porcher 
( 308 , p. 205). 
A strong infusion of indigo roots was said in India to destroy 
vermin in the hair.— Watt (422 , v. 3, p. 86). 
The seeds yielded a tincture which was used to destroy lice.—

LONCHOCARPUS spp. 
In 1924, when Mclndoo and Sievers ( 259 ) first reported on the 
insecticidal use of cube, it was impossible to give the botanical name 
of this plant. Since 1924 the botanists have become greatly interested 
in the South American fish-poison plants. Up to 1937 there was still 
oonfusion concerning the correct botanical names for the plants known 
locally as cube, haiari, and timbo, but more definite information on 
this subject was had when Krukoff and Smith ( 235 ) in 1937 reported that 
they had studied 11 species of South American rotenone-yielding plants, 
inoluding three new speoies (Loncho carpus sylvestris , L. martynii , and 
L. utilis ) , with special reference to native names, distribution, 
economic importance, and specimens examined. The literature was re- 
viewed by Roark ( 336 , 338 ) in 1936 and 1938. 
The six speoies that have been tested for insecticidal properties 
are reported below. 
LONCHOCARPUS CHRYSOPHYLLUS Kleinh. Black haiari (British Guiana) . 
Nekoe (Surinam) • 
The speoies appears well distributed in British Guyana and Surinam. 
The rotenone oontent of the roots averaged 2.1 percent, and the
