Hippoboscidae (Diptera Pupipara) 
Sternum thickly beset with small, stout setae. Anterior and middle tibiae 
with a single, stout inner apical seta, the posterior tibiae with two or three 
such setae; claws of each pair of equal size. Wings and halteres broken off 
in all the specimens examined. 
Abdomen with the dorsum marked by two diagonal lines which diverge 
from the base to the lateral margins well toward the apex, the base of each 
of the lateral areas thus delimited with a more or less circular, more heavily 
chitinized area, the whole sparingly beset with rather large setae. Remainder 
of the dorsum practically destitute of setae and membranous except for a 
small pre-apical plate. Basal sternite but slightly emarginate, thickly beset 
with small, stout setae and with a few longer setae. Remainder of the venter 
with numerous small, slender setae. 
Male. Length (on slide) 2*25 mm. In general very closely resembling the 
female. Genitalia (Fig. 2 G) with a pair of short external lobes (b) which are 
beset with small setae; internally with the inner ring-like piece (c) very sharply 
pointed at the apex.
