Its long, pointed epinotal spines are subparallel and directed backwaicl 

 and but slightly upward. The second specimen shows the structuie 

 of the thorax, petiole, postpetiole and gaster clearly. 



Genus JVotho^nyrtnica, gen. no v. 



I establish this genus to include Mayr's Macromischa rudis (whicli 

 may be considered as the genotype), M. rugosostriata, and i^etiolata 

 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 tibiae 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 

 Nothomyrniica resemble 'certain species of Tetramorium and Xipliomyrmex, 

 the former with 1 1- the latter with 12-jointed antennae, but in both 

 of these genera the middle and hind tibiae have spurs.

I have examined 

 eight workers of this 

 species from the Geo- 

 log. Inst, Koenigs- 

 berg Coll., namely No. 

 489/8739(MAYR'stype), 

 B 19 202, B 18 852, 

 XXB477, XTII8784, 

 B 236, B 18 981 and 

 one without a number; 

 also one from the 

 Brussels Museum (wi- 

 thout a number and 

 one (K 112j from the 

 Klebs Coll. 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
