Observations on the Ceratopogonine Midges of the Gold Coast with Descriptions of New Species

Abstract

This genus is closely related to Culicoides, Latr.It was erected by Kieffer in 1911 for the Indian species D. halophila, and subsequently (1913) divided by him into three sub-genera-DaSJ'Izelea (sene:;.stric.),Prokempia and Kempia-according to the nature of the wing hairs and the empodium.Later (1917) the last two sub-genera were given generic rank by this author, who then associated Prokempia with Dasyhelea but removed Kempia to the Atriclwpogort group.Still later (1919) Kieffer again placed Prokempia as a sub-genus of Dasyhelea.Prokempia apparently differs from Dasyhelea only in the absence or relative scarcity of the longer wing-hairs, and was separated for this reason; but although the dem:ity of arrangement of these hairs is much more uniform in Dasyhelea than in Culicoides, this character cannot, in our opinion, be considered of more than specifi.cvalue.
