NEW SPECIES OF INSECTS 

 COLLECTED BY C. WILLIAM BEEBE IN SOUTH AMERICA 



Among the small collection of insects which I brought hack 

 from Venezuela and British Guiana, a number proved to be new 

 to science. These have been kindly described for me by Prof. 

 Vernon L. Kellogg, Mr. A. N. Caudell and Dr. Harrison G. Dyar. 



There are two new Mallophaga, one new Mantis, and tioen- 

 ty-five new species, including six new genera of Moths. 



In a future scientific contributiofi to the Avifauna of these 

 countries I will have occasion to refer to many of these insects 

 as forming the food of certain birds. C. W. Beebe.

MALLOPHAGA FROM THE HOATZIN 



(Opisthocomus hoazin). 



By Vernon L. Kellogg, Stanford University, Calif. 



By the kindness of Mr. C. William Beebe of the New York 

 Zoological Park I have had the opportunity of examining a few 

 specimens of Mallophaga taken from the Hoatzin (Venezuela). 

 This curious bird, the single species of the pheasant-like, al- 

 though strongly aberrant family Opisthocomidae has for long 

 been a taxonomic puzzle to the ornithologists. It has been with 

 unusual interest, therefore, that I have examined these specimens 

 of their parasites. Although many of the Mallophaga are rather 

 catholic in their host likings some of them keep pretty strictly 

 to special bird groups. This is especially true of the parasites of 

 the Pheasants, the Phasianidae having their own types of Mal- 

 lophaga more conspicuously, perhaps, than any other bird group. 

 If then the Hoatzin is truly a close relative of the Pheasants, as 

 ornithologists seem to think, this fact might, perhaps, be indi- 

 cated by the affinities of its parasites.
