LONCHOCARPUS UTILIS A. C. Smith. Synonym: L. nicou (Aubl») DC. Cube 
and barbasoo (Peru). Barbasco (Ecuador). Timbo (Brazil). 
This species is found throughout the Amazon Basin, in Ecuador, 
Peru, and Brazil, and the natives generally recognize it as a very 
effective fish poison. Since all the specimens seen by collectors were 
either of cultivated plants or of plants growing in secondary forests 
on the sites of old Indian plantations, it is doubtful whether this species 
grows wild. The rotenone content of the roots averaged 12 percent and 
the extractive content 25 percent. The bulk of cube or barbasco roots 
now exported from Peru (iquitos) is this species. The roots are seldom 
collected in Brazil, as no large quantities of them appear to exist 
either in Aroazonas or Para.— Krukoff and Smith (235 ). 
This is the species that W. J. Dennis, head of the missionary school 
at Huancayo, Peru, first purchased at a shop in Huancayo for Dr. Eigen- 
mann to use in catching fish. Some of the roots were brought to the 
United States in 1920 by Dr. Allen, a student at Indiana University. 
These were later ground into powder, some of which was sent by Dr. Eigen- 
mann to the writer who first tested it on March 23, 1921.

Six patents (Brit. 230,203, Can. 247,378, Ger. 421,100 and 488,307, 
U. S. 1,610,167 and 1,885, 292) have been granted in which the alkaloidal 
extract of the seeds of these plants' are used for mothproof ing.-- Roark 
(333 , p. 56* 355 , p. 38); Roark and Busbey (346 , p. 29). 
LUPINUS PERENNIS L. Sun-dial lupine. 
Extracts from this plant were not repellent to the Japanese beetle.— 
Met z ger and Grant (277) . 
LUPINUS spp. 
A quantity of yellow lupine was grown but an extract of the roots 
gave negative insecticidal results.— Durham (125 ) . 
The leaves, stems, and roots of the three species of Lupinus tested 
had no marked poisonous action. Alcoholic extracts -of the seeds of a 
perennial and of an annual blue lupine were toxic, but the toxicity of 
these plants waB not of the same order as that of Tephrosia toxicaria 
and T. vogelii .— Tattersfield and coworkers (393).
