corneous

The wings of insects may consist either of one or two pairs—the anterior or upper pair, when two are present, being in some instances greatly modified and presenting a corneous condition.

Armature: applied to the spinous or chitinous processes on the legs, body or wings; or the corneous parts of genitalic structures.

The head is of a corneous, opaque substance.

The winter wheats are, as a rule, more soft and starchy than the spring wheats, which are usually corneous or flinty to different degrees.

In the next stage the larva has a solid corneous envelope and an oval shape, and, in its color, consistency, and immobility, resembles the chrysalis of a fly.
