white and black markings, the eggs are laid singly, and not laid 

 in raft-shaped masses, as in the case of the common species of

The adult Anopheles is frequently found in latitudes far north 

 of the malarial zone, and is not uncommon in states as far north as 

 Minnesota. It is long and slender with wings generally spotted. 

 When it is at rest, or biting, unlike the common " house mosquito," 

 it elevates the posterior part of its body, causing beak and body 

 to be in an almost straight line. The eggs are laid, singly or in 

 small groups.
