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. mollicula, 
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, 
1950, 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 
ForeTs Prionopelta marthae (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. zool.-bot. Ges. Wien 12: 737, 
worker; 1887, Ibid. 37 : 538, $ $ ). 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,
