FIG. 5. — Odontomachus haematodes Linn, a, young larva ; />, tubercle of the same. ning on the mesothoracic and terminating on the eighth abdominal segment, are clearly shown in Fig. 6, a. The bristly tubercles are essentially the same in structure as those of the younger larva, but they are relatively shorter and smaller. (Cf. Fig. 5, b, and Fig. 6, c.) The larvae of Leptogenys (Fig. 7) are remarkably slender and scarcely flattened on the ventral surface. In the young larvae (Fig. 7, a) the tubercles are distinctly curved and pointed, without apical bristle, and with only a few rather short bristles encircling the base (Fig. 7, d). In the adult larvae (Fig. 7, b and e) the tubercles are larger and shorter, with blunt or.
