PSEUDOCOLAPTES. — ATJTOMOLUS. 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 ^. M. Boucard, too, did not at first 

 consider the specimen he obtained in Costa Rica sufficiently distinct ^, though he 

 subsequently described his bird as P. costaricensis ^. In the meantime Mr. Ridgway 

 called it P. lawrencii, 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. boissoneauti. 



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.
