Termitophile Distribution and Quantitative Characters as Indicators of Physiological Speciation in British Guiana Termites (Isoptera)

During a study of the termites of the tropical rain forest of Kartabo, British Guiana, in 1919, 1920 and 1924, a collection of termitophilous Staphylinids was made from colonies determined as Nasutitermes (N.) guayanae (Holmgren). The fact that four species of beetles were found together in certain nests while two different species were found together in other nests excited the author's curiosity and a more thorough analysis involving a statistical study of variation in the host termites was undertaken. I am indebted to Dr. Sewall Wright for suggestions concerning statistical methods and a critical reading of the manuscript.
