A hexane-soluble contact mating stimulant pheromone, bioassayable by sexual response to tethered males, was extracted by prolonged (5 day) washing of whole, freshly-killed male and female C. melleus. Assays were performed by allowing males to manipulate (with their feet) very small cubes of cork on which extract was deposited by evaporation. Silica-gel chromatography of crude extract yielded total hydrocarbon fractions to which, when assayed at 10 .female..female. (or .male..male.) equivalents, 75% or more of the males responded. The diluted total hydrocarbon fraction from females elicited significant male response at 1 .female. equivalent, but not at 1/10 equivalent or less. Assays of synthetic n-alkanes showed no activity, but among several methyl-substituted alkanes (2-methyl-docosane, 8-methyl-docosane, 9-methyl-tricosane, 10-methyl-docosane), the first 3 produced significant response assayed at 1 .mu.g/model.
