Fig. l.^Larva of Tarache lucida. . » Eupseudoiyiorplia, Cydosia, Grceperia, Tarachidia and some other genera have the typical trifid neuration of the hind wing of the subfamily Acronyctince, but are by facies and other characters closely allied to the Erastriance, the larvae of such as are known having the anterior prolegs aborted, which is the essential distinction between the two subfamilies. Larvce smooth, the warts with single hairs, the anterior or two anterior pairs of prolegs absent, and in method of progression more or less semiloopers. Key to the Genera. A.
