These skins agree well with the typical specimens in m y collection. " This little Tyrant, which is unknown to me, seems to belong to a genus between Pyrocephalus or MyoBius and Muscisaxicola. Like the two former (according to m y information from Mr. Dallas) it is usually seen upon a dry branch, and is very fearless. Examining the stomachs of many specimens, I found large larvae of such insects as are generally seen in places where cattle have been feeding, and many coleopterous insects, from which it may be inferred that the birds hunt on the wing and on the ground.

From the description I have received of it, this bird clings to the branches and twigs in attitudes as grotesquely as a tit-mouse. I received three examples, all females.
