NOTE ON THE SETÆ OF THE LARVÆ OF THYATIRIDÆ, AND A CORRECTION

Extract

Recently I have examined the larvæ of some European Thyatiridæ, and find the setæ arranged exactly as in our species. [See Proc. Boston Soc. Nat. Hist., 1894, p. 399.] The supplementary seta behind iii. varies a little in position, but is uniformly present. The species examined are Habrosyne derasa, Thyatira batis, Bombycia or, B. duplaris, Asphalia ruficollis, and A. fluctuosa. A correction must be made in my description just referred to (pp. 400–401). The species there described in all its stages as “Thyatira scripta” is really Pseudothyatira expultrix. The following list may straighten out the matter:—

Habrosyne scripta.

1883. Thaxter, Papilio III, 10. Describes egg and sixth stage.
