NOTES ON HXPPOBOSCIME 
13. A SECOND REVISION OF THE HIPPOBOSCINAE 
By J. Bequaert 
Harvard Medical School and School of Public Health, 
Boston, Mass. 
Since the publication of my synopsis of the Hippoboscinse 
(1931, Psyche, XXXVII, (1930), pp. 303-326), much addi- 
tional information has come to light. One new species was 
described recently by the late G. A. H. Bedford and I was 
able to study several types, including those of H. fulva 
Austen. 
In the alphabetical list of names (p. 306), martinaglia 
Bedford should be inserted as the ninth valid species ; longi- 
pennis Fabricius is the valid name of capensis v. Olfers, 
which becomes a synonym; and variegata Megerle (not to 
be credited to Wiedemann) is the valid name of maculata 
Leach, which passes in the synonymy. 
As pointed out before, the Hippoboscinse differ from 
other members of the family in several important charac- 
ters. To those listed before may be added the presence of a 
pair of deep, more or less pit-like depressions, placed later- 
ally on the suture between mesonotum and scutellum; also 
the well-defined pale yellow or white spots of head and 
thorax, which are not duplicated elsewhere in the family. 
While in other Hippoboscidse color differences are of little 
or no specific value, in Hippobosca the shape and arrange- 
ment of the pale spots produces a pattern to a large degree 
diagnostic for each species. In this respect, there is an ob- 
vious analogy to the characteristic pattern of pale spots 
found in many species of ticks ( Amblyomma and Der?na- 
centor ) . 
I have been at pains to discover additional specific charac- 
ters, particularly in the case of closely allied forms. The 
chetotaxy has been neglected thus far, yet offers reliable dif- 
ferences which should be investigated by the accepted bio-
