Ants of the Genus Macromischa 
177 
on epinotal declivity. Petiole, postpetiole, gaster and legs 
minutely punctate. 
Hairs white, stiff, erected, moderately abundant, longer 
on thorax. 
Head green, thorax red, with violaceous and greenish re- 
flections in certain lights. Epinotal spines brownish red. 
Pedicel, base of femora and tip of tarsi yellowish brown. 
Petiolar node, post-petiole, gaster, remaining of legs and 
antennas black. 
Described from a single specimen collected by Colonel 
G. Natenzon in “Pan de Guajaibon,” province of Pinar del 
Rio, Cuba. 
Holotype in the collection of the M. C. Z. 
This species is related to M. squamifera Roger and M. 
creightoni Mann, but readily distinguishable by the longer 
epinotal spines, coarser sculpture and by the red coloration 
of the thorax. 
It is with pleasure that I name this species for Dr. 
Thomas Barbour, to whom I am very much indebted for 
many favors. 
Macromischa manni Wheeler var. villarensis var. nov. 
Worker. Length 5.2 to 5.8 mm. 
This form has the same size, sculpture and pilosity as 
M. manni, differing principally by the shape and position 
of the epinotal spines which in var. villarensis are some- 
what smaller, much more divergent, V-shaped, closer to- 
gether at their bases, lacking the sigmoidal curve of manni, 
directed backward, upward and slightly bent inward at 
their tips; the basal half of each spine is broader and lat- 
erally compressed, the dilatation ending abruptly at the 
middle as in M. porphyritis var. latispina Wheeler. 
Described from many specimens collected by Pedro Ber- 
mudez in several localities of Northern Santa Clara, Cuba. 
They were on limestone cliffs, “with the gaster bent and 
upraised” (Bermudez). 
Type locality: “La Puntilla,” Remedios, Santa Clara, 
Central Cuba.
