THE ANATOMY OF THE ADULT MOSQUITO 111 



the above description, which applies only to Gulex, there is 

 no noticeable difference between the internal anatomy of 

 the different genera ; and, putting aside of course the 

 generative system, the two sexes closely resemble each 

 other, so that I cannot confirm Prof. K. Blanchard's state- 

 ment {Bull. Acad, de Medecine, 3e. Ser., t. xliv., p. 21.) that 

 the buccal apparatus of the ? , is much the more developed ; 

 for I find that, for all purposes of anatomical investigation, 

 one may use either the J , or the ? , , as interchangeable 

 material. 



The above account will, I think, be found sufficiently 

 detailed to serve as an introduction to those engaging in 

 work on the subject, but is necessarily a mere sketch of the 

 subject, for so many points force themselves on one's notice 

 that it is difficult to avoid being tempted into too great 

 detail. It would indeed be easy to fill as large a work as 

 the late Prof. Huxley's wonderful work on the cray-fish if 

 not to copy the luminousness and charm of the author, but 

 anything beyond an outline of the subject would be out of 

 place in a book like the present.
