In France much interest has "been manifested in rotenone, and 
popular reviews on this subject that include reference to Lonchocarpus 
have been published by J. Chevalier (75); Guerin (178); and Scarone 
(366). A. Chevalier (73) in 1937 reviewed information on fish-poison- 
ing plants of the genera Tephrosia and Mundulea. Reference is made to 
Lonchocarpus scriceus L. , the bark of which is used to poison fish 
in America.. 
Frappa (152) in 1937 reviewed the botany of Tephrosia, Mundulea, 
Lonchocarpus and Derris with special reference to the possibility of 
their cultivation in Madagascar; and summarized the action of rotenone 
on mammals, fishes and the different orders of insects. 
Much fragmentary information concerning Lonchocarpus is scattered 
through the literature. Brief abstracts of these articles are as 
follows: 
An abstract of Martin's paper on timbo is given by an anonymous 
(1) writer in the Pharmaceutical Journal and Transactions for June 16, 
1877. 
Hanriot (187) in 1907 pointed out that tephrosin was analogous 
to but not identical with the timbo ine of Pfaff (Arch. Pharm. 229: 
31-48. 1891) and the derride and pachyrizide of Van Sillevoldt 
(Arch. Pharm. 237: 595-616. 1899). 
Sack (363) in 1910, in a list of plant products of Dutch Guiana, 
listed Lonchocarpus sp. , called nekoe or stinkhout. Reference is made 
to its use as a fish poison and to the work of Borst Pauwels 
(Dissertation, Leyden, 1903). 
Zornig (480) in 1911 included Lonchocarpus cyanescens Benth. 
in a list of plants that yield indigo. 
DeSornay (385) in 1913 gave information concerning the uses of 
Lonchocarpus formosianus , L. latif olius , L. oxycarpus , L. sericeus , 
and L. sp_. (Savonnette blanche) as medicine and in industry. 
Tschirch (408), in an article on "Cortex Derridis" published 
in 1925, stated that the derrid of Greshoff and SiLtevoldt also 
apparently occurs in Lonchocarpus and other leguminous plants. 
Campbell (59), in his review of information on the insecticidal 
value of rotenone issued in 1932, referred to Bishopp et al. who tested 
powdered cube against cattle grub, and Clark who isolated deguelin 
from cube. Cube root has been received by the U. S. Department of 
Agriculture that was riddled by tunnels of a bostrichid beetle. 
Cory (92), at the 1934 meeting of the American Association of 
Economic Entomologists, acted as discussion leader of the topic, 
Arsenical substitutes for insects attacking vegetable crops. Cube 
was mentioned by Huckett and Hervey of New York; Cubor and Kubatox 
by Turner of Connecticut, Watson of Florida and Marcovitch of
