fusiform

It is probably caused by two micro-organisms living in symbiosis—one a fusiform bacillus, the other a long spirillum (Fig. 124).

In some the figure approaches to fusiform, as in most of the moths of the Fabrician genus Lithosia.

Fusiform: Outline of a parsnip, narrow at either end, broadest below the surface (Fig. 151, k).

The larva has a soft fusiform body, surmounted by a somewhat globose head.

The elaters are never fusiform, the apices always abrupt in their acumination, and the sculpture irregular and uneven.
