AMBLYCERAN MALLOPHAGA (BITING LICE) 
FOUND ON THE BUCEROTIDAE (HORNBILLS) ! 
By Rospert E. Ese. ? 
Mallophaga of the genera Chapinia and Bucerophagus of the am- 
blyceran family Menoponidae are found only on hornbills. The 
purpose of this paper is to redescribe and illustrate the known species 
in these genera, describe new species encountered, and compare 
the classification of these lice with that of the hornbills. Menoponidae 
have been examined from 53 species or subspecies of hornbills (table 
13). Presented are descriptions and illustrations of 22 species of 
Menoponidae of which 17, including 12 new, are species of Chapinia, 
3 are species or Bucerophagus, and 2 are new species in a new genus, 
Bucerocolpocephalum. 
No previous attempt has been made to examine all the Menoponidae 
from the hornbills. Clay (1947) included Chapinia and Bucerophagus 
in her key to the genera of the Menoponidae, but her figures 8 and 9 
of the antennae of these genera were transposed accidentally. The 
genus Chapinia was described by Ewing (1927) for his species C. 
robusta; later it was described by Bedford (1930) for Menopon bucerotis
