got their probosces into my skin. Their red colour was also 
very striking, and the hairs on the back and posterior part of 
the thorax. During life the eyes are emerald green in colour, 
but become darker after death.”

Additional localities.—British Guiana (Dr. Low) ; Para (Dr. 
Durham) ; Trinidad (Dr. C. H. Hewlett). 
Notes.—The specimens from Trinidad were caught in a house 
(Hewlett) at Cedros and at Crunupia. One ¢ was very small— 
5 mm. in length. 
Regarding the British Guiana specimens, Dr. Low writes as 
follows: ‘‘ While proceeding to the Tapacorma Lake from Anna 
Regina, on the coast of British Guiana, along a water-course, 
with four Indians in a canoe, we left the cultivated zone and 
passed through some low bush,* which in places was completely 
arched over the channel. This made a subdued kind of lght, 
and very quickly large numbers of this brilliant mosquito 
descended. They bite through one’s clothes with great ease, and 
the bite was very painful. They were not very agile, however, 
and were easily caught in tubes. This was at 9 a.m. in the 
morning, and, strangely enough, when again re-passing this place, 
ten days later at 4 p.m., I only caught one specimen. This would 
indicate that they bite more readily in the mornings. Along 
with them three other species also attacked us, and all bit the 
Indians quite as readily as myself.”

* Low bush is the term applied in British Guiana to the vegetation, 
really forest, that grows up on land that has once been cultivated or 
cleared. It is very thick and almost impossible to walk through. It is 
quite different in its nature to the virgin forest that one finds further up 
in the interior; there the undergrowth is slight, rendering progression 
easy. The mosquitoes in these areas as a general rule are different.
