1944] Genus Pseudomyrma 87 
It is not unlikely that further collections in Peru will unearth 
numerous intergrades between the two new varieties. 
Holotype No. 89, Haskins Collection. 
Pseudomyrma gracilis var. longinoda var. nov. 
Worker. 
Length 8-8.5 mm. Color black, except for the mandibles, 
clypeus, peduncle of the petiole, which are yellow or reddish 
yellow, antennae, tibiae and tarsi brownish red. The coloration 
conforms to the description of the type P. gracilis (Faber, not 
Emery). Head opaque, rest of the body subopaque (as in P. 
bicolor). Postpetiole much longer than broad, piriform, as in 
dimitiata (more nodiform in bicolor , sericata mexicana) . The 
peduncle is very long and has a secondary swelling at the loca- 
tion of the spiracles (this feature is much less developed in all 
other forms). Pronotum powerfully marginate with large over- 
hanging shoulders, much more pronounced than in agilis. The 
clypeal lobe is very broad and nearly rectangular, as in some 
forms of the type series. 
Type locality: Bella Vista, Peru. From fallen leaves. 
We name this new form because it shows two characters in 
extreme development: the length of the petiolar peduncle and 
the margination of the thorax. It is nearest to agilis , from 
which it differs by a very much higher mesonotal disc, as well 
as by accentuation of some of the distinctive characters of agilis. 
Cotype No. 90, Haskins Collection; one pin has been depos- 
ited in the Museum of Comparative Zoology, where it has been 
labelled Cotype 26812. 
Pseudomyrma kuenckeli var. hondurana var. nov. 
Worker. 
Differing from the type in color pattern. Head reddish brown, 
darker than in the type; thorax dark reddish; gaster brown; 
front of the head and mandibles yellow. 
The varieties of the species kuenckeli are separated mainly 
by their color pattern. We have not enough material on hand 
to make any positive statements as to whether color differences 
can be regarded as a good character for the separation of named 
varieties. 
Type locality: Honduras (Bates coll.). Other specimens of 
this variety in the Haskins Collection are from Guatemala.
