1930] A Second Note on Gesomyrmex 37 
central portion, of the pronotum dark brown. In some 
specimens the pleurae and epinotum are reddish brown. 
Basal portions of the several gastric segments distinctly 
brownish. Mesonotum broader than long and much more 
convex than in kalshoveni. Petiole thicker above and less 
distinctly cuneate. 
Worker media. — Length 4.5-6 mm. 
The larger specimens are as large as the maximse of 
kalshoveni and differ from them only in their deeper yellow 
coloration, in having the spot on the vertex and the disc of 
the pronotum brown, though paler than in the maxima, 
and in the thicker and blunter petiolar node. In the smaller 
specimens the brown on the vertex and pronotum becomes 
fainter or disappears altogether. 
Worker minima. — Length 2.5-3. 5 mm. 
Without dark markings and very similar to the minima 
of kalshoveni, but with the petiolar node distinctly thicker, 
less compressed above and therefore less cuneate in profile. 
The general yellow color of the body seems to be somewhat 
darker. 
Female (dealated). — Length nearly 9 mm. 
Closely resembling the female of luzonensis in structure, 
pilosity and sculpture but differing in coloration. Paler and 
more ivory yellow, with a large rhomboidal spot on the 
middle of the head, covering more than the ocellar region, 
the wing insertions and the discal portions of the pronotum 
and epinotum dark castaneous brown. Dorsal surface of 
the same color, with the borders of the segments and a 
transverse band at the base of the first segment yellow. 
Male. — Length 3.6 mm. 
Head small, including the large, convex eyes somewhat 
broader than long, broadly rounded behind, with extremely 
short cheeks. Ocelli large and prominent. Clypeus some- 
what broader than long, convex in the middle, anteriorly
