The long-awned species of Festuca have compact stiff panicles and narrow or setaceous leaves. |
Antennae incrassated and plumose in basal half, the joints moniliform, apical half setaceous. |
The two endemic Rubi have the prickles reduced to the setaceous condition, and the two palms are unarmed. |
The antenn are about an inch long, slender, setaceous, and gradually diminishing from the base to the extremities. |
Yet insects that have filiform or setaceous antenn appear often to use them for exploring. |
Continuing in this way, the stylets work like a push drill that penetrates the host skin with the toothed tip region, and the sclerotised, setaceous inner edge possibly widens the puncture wound. |
