Worker
In this form the dorsum of the thorax is impressed at the mesoepinotal suture, as in the subspecies Veromessor julianus clarior. It differs from clarior, however, in its smoother cephalic sculpture, the striae in the smaller specimens being scarcely visible. Furthermore, the epinotal spines are shorter, approaching the condition found in the typical Veromessor julianus. The color of the subspecies is less clear than that of clarior, the head especially tending toward a muddy, brownish red. The yellowish spot at the base of the first gastric segment, which appears to be a fairly constant character in clarior, is reduced in size or absent altogether in manni. In addition this subspecies appears to be smaller than either clarior or the typical julianus. This distinction must, however, be used with caution since the type series consists of few specimens and it is entirely probable that the examination of additional material will prove this statement to be erroneous. The length of the specimens examined varies from 4.5 mm. to 6 mm.
