be found. Eight new species are now described. The 
Oriental Region is also rich in specimens, five new species 
are now described and one from Australia wrongly placed 
by me under P. interponens, Wlk., in aformer paper. Many 
of the specimens dealt with in this genus and in Dysmachus 
are in the Imperial Entomological Economic Collection.

The following species described from this region of Africa, 
not included in the table, are: P. trichozonus, Loew, in the 
P. fasciatus group, with yellow pubescence on the forehead ; 
P. mediospinosus, Speiser, in the same group with the whcle 
underside of thorax and abdomen bright yellowish-red 
haired; P. guineensis, Wied., moustache snowy white, 
genitalia with tuft white hairs, scutellum with white hairs 
and bristles—a large species, measuring 26 mm.; ? Asilus 
scutellatus, Macq., and Asilus albitarsatus, Macq., both of 
which probably belong to the genus Promachus—the latter 
has the style of antennz a little swollen at the end, and 
might therefore belong to the genus Philomachus, the former 
is described as having pale yellow legs and the posterior 
part of thorax and the scutellum testaceous red.
