 malarial, mosquitoes. The pupae are, however, not so easy to 

 distinguish. The adults of Anopheles have spotted wings, a 

 character which only a few of our other mosquitoes have. 

 With most mosquitoes the maxillary palpi (see Fig. 159) of 

 the male are long and those of the female very short, but the
