NOTES ON A COLLECTION OF MOSQUITOES FROM 
WEST AFRICA, AND DESCRIPTIONS OF 
NEW SPECIES 
By F. V. THEOBALD, M.A., F.E.S., etc. 
The collection of mosquitoes brought back by the members of the expedition from the 
West Coast of Africa contained twenty-six distinct species. Of these only five had been previously 
described. Thirteen of the new species are described in my Monograph of the Culicidae shortly 
to be published by the Trustees of the British Museum, and the remaining new ones here. 
The collection includes the genera Anopheles, Meigen (two species), Mucidus Theobald (one 
species), Eretmapodites Theobald (one species), Stegomyia Theobald (five species), Culex Linnaeus 
(nine species), Panophtes Theobald (one species), Taeniorhynchus Arribalzaga (modified) (two 
species), Aedes Meigen (one species), \J ranotaenia Arribalzaga (three species). 
The collection contained over two hundred and fifty specimens, including two midges 
(Chironomidae). Some of the types have been given me by the collectors for the British Museum. 
Genus Anopheles. Meigen ( i 8 i 8 ) 
(Syst. Beschr. Eur. Zweifl. his. p. 1-13, 1818) 
I. Anopheles eostalis. LoEW 
{Berlin Ento. Zcitschr. p. 55, 1866) 
A number of this species taken at Bonny, Duke Town, Bugama, Bakana, Akwete Prison, 
s.s. Sobo (off Bakana), Lokoja, and at Old Calabar. They show considerable variation both in 
colour and size, but the costal markings and the spots on the femora remain distinct in all the 
specimens. Those from Old Calabar are considerably paler and somewhat smaller than those 
from Bonny. The specimens also show considerable variation in leg banding, it being almost 
absent in some, very distinct in others. 
They were captured during the following months — April, in Duke Town ; May and 
June, at Bonny; August, at Akwete; September, at Lokoja; in June, off Bakana ; and June 
at Opobo. 
II. Anopheles barbirostris. Van der Wulp var. Africanus 
(Leaden Museum Notes, VI, p. 48) 
Three dark 9 Anopheles taken at Old Calabar in April are undoubtedly this species. They 
resemble in all structural respects the Asiatic form. The only difference to be noticed is that 
some pale scales are scattered over the wings, and there are no traces of leg banding. There is 
nothing upon which a new species could be founded, but they are certainly a local variety, and 
they look longer-legged than the Malay and Indian specimens I have seen. 
The examination of the $ ungues might prove it to be quite distinct. I propose to call it 
variety' Africanus ; the variety based solely on the mottled wing scales.
