SOME BIRD LICE OF THE GENERA ACIDOPROCTUS AND 

 QUADRACEPS (NEOTROPICAL MALLOPHAGA MISCEL- 

 LANY NO. 3) 



By M. A. Carriker, Jr. 



Opportunity is here taken to restiidy the Old World mallophagan 

 species Acidoproctus rostratus (Riidow) and Quadraceps annul atus 

 (Denny), with reference to certain species from Colombia, and to de- 

 scribe two new species from South America. Thanks are extended to 

 Dr. G. H. E. Hopkins for his cooperation in supplying the Old World 

 material. All measurements are in millimetei's.

 fide Hopkins.) 



Dr. Hopkins, in a recent letter to me, says of this species : "The type 

 being lost, somebody should erect neotypes. I dealt with this species 

 in a previous paper (Ann. Mag. Nat. Hist., ser. 11, vol. 2, p. 195, 

 1938) , and I regard Dendrocygna viduata as the type host, though that 

 is anybody's guess, because the type was a nymph and it would cer- 

 tainly have been impossible to say from what species of Dendrocygna 

 it got onto the goose (skin ?)." 



If the type of A. rostratiis was collected on a skin of Alopochen 

 aegypticus^ as Hopkins suggests, it must have certainly straggled there
