Remarks .—A very distinct and easily recognised species. The peculiar 
blackish-brown spots and lines on the thorax give it a very characteristic 
appearance. The first specimen of this mosquito appears to have been sent 
by Dr. Wray of Perak to the British Museum. Mr. Butler stated it was 
fairly common in Klang jungle but I only obtained one specimen there. 
Rare specimens have also been found on the East Coast.
