PSEUDOCOLAPTES.—-AUTOMOLUS. 153 
Two species, rather doubtfully separable, are included in Pseudocolaptes: one of 
these ranges throughout the Andes from Venezuela and Colombia to Bolivia; the 
other occurs in Costa Rica and the State of Panama. 
1. Pseudocolaptes lawrencii.

This species is very closely allied to the well-known widely ranging P. boissoneauti, 
so much so that Salvin hesitated to separate it from a single specimen from the State 
of Panama, believed by him to be hardly adult 1. M. Boucard, too, did not at first 
consider the specimen he obtained in Costa Rica sufficiently distinct 2, though he 
subsequently described his bird as P. costaricensis *. In the meantime Mr. Ridgway 
called it P. lawrencit, from adult and young specimens sent him by Mr. Zeledon from 
Costa Rica?. All these birds, so far as they go, confirm the characters of distinction 
given it by Mr. Ridgway, except perhaps the markings of the jugulum, which seem to 
us to be variable in intensity. There remain, however, the fawn-coloured cervical 
tufts and the dark primaries, which in P. boissoneauti are pure white and dark umber 
respectively. We note, nevertheless, that Bolivian examples have the cervical tufts 
just tinged with buff, though the primaries are umber, as in typical P. boissoneautz. 
Of the habits of this species nothing has been recorded, but of P. boissoneauti, 
Salmon (P. Z. S. 1879, p. 521) tells us that it feeds on insects, makes its nest in a hole 
in a tree, and lays white eggs.
