The CuLiCALES may be divided further into two main groups as follows :-— 

 Sub-section I. Cclicides. Palpi of (5 longer than those of Q. 

 Sub-section II. Aedides. Palpi similar in both sexes. 



Further sub-division, except into genera, is unnecessary, and probably not 

 advisable. 



In the following table are included all those forms of the €uLiciDES 

 (Theobald's sub-families Culicinae and Heptapldebomyihae) which have no flat 

 scales on the scutellum or on the middle part of the head. The genus Liidloma 

 has also been included owing to the similarity of the females to Culex, and the 

 fact that not all the species have a flat-scaled head.
