Classification based upon summary of factors in three preceding' schemes. Right extreme indicates presence of definite ootheca, long duration of copulation, superposition of body of male during copulation (in Mantidse), absence of organs for production and reception of sounds and the absence of an ovipositor. The left extreme indicates a complication of movements prior to- copulation, absence of an ootheca, eggs laid singly, superposition of body of female during copulation, presence of stridulating organs and organs for the reception of sound. Forms placed in various intermediate positions show a lesser degree of specialization. hand the ovipositor is well developed and specialized, the bodies are found in various positions during the copulation but there is no superposition of the body of the male, eggs are laid singly or in masses of two or three, sounds produced consist of" chirps, and the organs for the reception of sounds are located in the anterior tibia. The Acrididae and the Phasmids are separable because of differences already mentioned. A subdivision of the Locustidae is made because some forms have suffered a degen- *Horizontal plane indicates general direction and extremes of summary oF factors and processes used in classification. Lines inclined upward indicate development and specialization of organs and processes, while lines inclined downward indicate degeneration or loss of organs.
