segments and their appendages, ten of the New England species of Corythucha were separated. These were: C. marmorata, C. cydoniae, C. pruni, C. arcuata, C. molliczila, C. ciliata, C. caryae, C. pergandei, C. pallipes, and C. ulmi. The remaining species could not be separated: C. heide- manni, C. juglandis, and C. coryli.
COMPOSITION OF THE ANT TRIBE TYPHLOMYRMICINI. - In 1911, Emery (Gen. Ins. 118: 32) raised a subtribe of his tribe Ectatommini to include the genera Typhlomyrmex Mayr, Prionopelta Mayr and Rhopalopone Emery, and named this subtribe Typhlomyrmicini. It has already been proposed on morphological grounds that Prionopelta be removed to tribe Amblyoponini and Rhopalopone remain in tribe Ectatommini, while Typhlomyrmex has been seen as the sole group representing an isolated line (Brown, 19150, Wasmann Jour. Biol., San Francisco, 8: 243-244.) The tribal name Typhlomyrmicini is hereby placed in use to include the Neotropical genus Typhlomyrmex. Tribal distinction is considered to be complete. The male specimen without head, doubtfully referred by me in 1950 (loc. cit.) to Prionopelta, is now definitely recog- nized as a Typhlomyrmex of unknown species. It appears characteristic of Typhlomyrmex males that vein Mfl arises basad of cu-a. Other characters of the genus and tribe will be brought out in a forthcoming key to the ponerine genera. Examination of a cotype ("Zig-zag, Venezuela") of Forel's Prionopelta mrthae (1909, Deutsch. ent. Zeitschr., p. 240, worker) in the Museum of Comparative Zoology shows that this species must be removed from Prionopelta and placed as a new synonym of Typhlomyrmex rogen- hoferi Mayr (1862, Verh. z001.-bot. Ges. Wien 12: 737, worker ; 1887, Ibid. 37 : 538,
s 8 ) . Comparison was made
with workers of T. rogenhoferi determined by Mann and Wheeler from Para, Brazil (Mann leg.), and these proved closely similar. The marthae type differs distinctly from types of T. pusillus Emery and T. robustus Emery in the Museum of Comparative Zoology. -WILLIAM L. BROWN, JR., Museum of Comparative Zoology.
