The main purpose of this note is to give a name to the Malayan Culicoides that sucks blood from the abdomen of Anopheline mosquitos, and thus to afford cover for the publication of some very interesting observations made recently upon this species by Dr. W. A. Lamborn. At the same time, some account is given of the very few additional specimens of Oriental Culicoides in the British Museum—most of which were also collected by Dr. Lamborn in Malaya; and the opportunity is further taken to describe two other apparently new species of the genus, from Somaliland and Jamaica, respectively, which have recently been received at the Museum.
