Its long, pointed epinotal spines are subparallel and directed backward 
and but slightly upward. The second specimen shows the structuie 
of the thorax, petiole, postpetiole and gaster clearly. 
Genus Nothomyrmica , gen. nov. 
I establish this genus to include Mayr’s Macromischa rudis (whicli 
may be considered as the genotype), M. rugosostriata, and petiolata 
and a new species, since it is evident that these cannot be included 
in Macromischa. Roger based this genus on a number of Cuban 
species. It has been recently redefined by Emery to include also 
several other neotropical forms, which lack the spurs on the middle 
and hind tibise and have a distinctly pedunculate petiole, campanulate 
postpetiole and a short, convex thorax, usually without mesoepinotal 
constriction. In the general structure of the body the species of 
Nothomyrmica resemble certain species of Tetramorium and Xipliomyrmex, 
the former with 11- the latter with 12-jointed antennae, but in both 
of these genera the middle and hind tibise have spurs.

I have examined 
eight workers of this 
species from the Geo- 
log. Inst. Koenigs- 
berg Coli., namely No. 
489/8739(MAYR’stype), 
B 19202, B 18 852, 
XXB477, XIII 8784, 
B 236, B 18 981 and 
one without a number; 
also one from the 
Brussels Museum (wi- 
thout a number and 
one (K 112) from the 
Klebs Coli. The coar- 
se, reticulate - rugose 
sculpture has been 
described by Mayr and is clearly shown in the accompanying 
figure. This species closely resembles Myrmica longispinosa Mayr
