158 DENDROCOLAPTID. 
This is the palest of all these forms on the upper surface, and, moreover, has the 
forehead and anterior portion of the crown of the same colour as the back, instead of 
being of a uniform dark cinnamon or rufous-brown tint over the whole crown; the 
sides of the head below the eyes are also clearer cinnamon than in any of the allied 
forms. In other respects it most resembles the Guatemala bird from the Volcanoes of 
Agua and Fuego. 
Mrs. Herbert Smith’s large collection made in the Sierra Madre del Sur in the 
summer of 1888 contains two specimens of this species—the male taken at Omilteme 
at an elevation of 8000 feet above the sea; the other, marked female, at Xautipa, a 
village in the same range of mountains, both places being not far from Chilpancingo, a 
town on the road from the port of Acapulco to the interior. 
The female differs slightly from the male in the almost total absence of the rufescent 
colour on the nape, the upper surface being thus almost uniform as far as the rump. 
We have not enough specimens to be able to judge if this difference is a normal one 
between the sexes, but from analogy it would not be so.

On the upper surface this is the darkest of all these forms of Automolus, darker even 
than A. rubiginosus, and has much darker wings. On the underside it is more like 
the Guatemalan A. umbrinus, but the sides of the head and flanks are much darker 
and the wings outwardly very differently coloured. 
Of this species we have only a single male specimen, which was sent us by our 
collector, Enrique Arcé, in one of his last collections. He obtained it near a place 
called Bibalaz, on the slopes of the Volcan de Chiriqui.
