308 A Monograph of Culierdae. 
Genus 39. HAEMAGOGUS. Williston. 
(Mono. Culicid? 11) p- 238, 1901.) 
A number of fresh specimens of the previously known species 
(cyaneus) have been received and a new species added to the 
genus. 
Harmacocus cyaANgeus. Fabricius. 
Culex cyaneus. Fabricius. 
Haemagogus splendens. Williston. 
(Syst. Antl., 35, 9, Fabricius ; Mono. Culicid. II., p. 239, 1901, Theobald.) 
Additional localities.—British Guiana, on the Demerara River 
at Cara Cara Creek and at Pickersgill (Low); Para (Dr. 
Durham) ; Trinidad (Dr. Lassalle). 
Notes and observations.—Dr. Low sends the following notes 
on this species: “I caught one specimen in St. Vincent at the 
outlet of a valley on the leeward coast (Cumberland valley). I 
was sitting on a log in the bright sunlight, twelve noon, when it 
came and settled on my leg. I kept it alive in a test tube for 
two days and took it up to town to try to get it to bite a man 
with F. demarquaii embryos. It unfortunately died just before 
IT arrived, so I mounted it and sent it, in the St. Vincent 
collection. The natives in the village of Calliagua, a place on 
the sea-coast, told me that they knew it well, and that it was 
found in the hills behind that place. It therefore seems to be 
fairly well distributed in the island.” 
Dr. Low also sent the following interesting note: “I think 
now a bush mosquito spreads Filaria perstans and F. demarquatt ; 
it does not matter how far one is from the sea as long as the 
bush is not disturbed. I suspect a metallic blue mosquito as 
having something to do with it, as I] have found it everywhere, 
where I have got the filariae. FF. perstans, I think, is undoubtedly 
spread by a bush insect. Elephantiasis is unknown, because in | 
the forests Oulex fatigans is not found.” 
HAEMAGOGUS ALBOMACULATUS. 2. sp. 
Head blue, metallic; thorax shiny black, with bronze, green 
and blue scales; abdomen metallic violet, the penultimate and 
antepenultimate segments with a median patch of white scales,
