1944] Genus Pseudomyrma 83 
Type locality: Mirador, Mexico. 
Described from 3 workers, labelled Cotype 26810, in the 
Collection of the Museum of Comparative Zoology. The Has- 
kins Collection has 6 workers from Camaron, Mexico. 
Pseudomyrma colei sp. nov. 
Worker. 
Length 4.5 mm. Head 1% times as long as broad, broader in 
front, with very round occipital corners and straight posterior 
edge. Mandibles strongly striated, with two apical, but no basal 
teeth. The clypeus with a very short and narrow anterior lobe 
which is weakly excised in the middle. The eyes are about half 
as large as the sides of the head and are flat. The scapes reach 
the middle of the head. The head is finely punctate and shiny. 
Prothorax broader than its length in the midline, not margined, 
finely punctate. The mesothoracic disc is transverse. The base 
of the epinotum is twice as long as broad, broadest at the level 
of the stigmata, a little narrower at the junction with the epinotal 
declivity. The petiole from above is shaped as in P. decipiens. 
The postpetiole is V/ 2 times as broad as the petiole, broader 
than long, and nodiform. The thorax in profile is slender, a 
little convex above, strongly impressed at the mesepinotal su- 
ture. The base and declivity of the epinotum form a blunt 
angle. The petiole in profile is distinctive and separates this 
form from all other related species. It is twice as long as high 
and has four distinct faces; the slightly concave anterior face 
rises from a short peduncle; the superior face is convex and 
higher behind than in front; the posterior face is convex and 
abrupt and ends in a sort of posterior peduncle. Below, the 
petiole has a small blunt tooth, shaped as in P. elongata. 
The new species is nearly naked : the pilosity is restricted to 
the mouth, and the extremely fine pubescence to the funiculi 
and the tarsi. Color: tibiae antennae, tarsi and tip of the gaster 
yellow. Head and prothorax reddish brown, the rest of the body 
almost black. 
Type locality: Bella Vista, Peru (800 m. sea level). Taken 
from an unknown tree.
