Genus CCCXXXI.— Adela, Latreille. 



Palfn four ; labial slender, curved upward and sparingly clothed with long 

 loose hairs, the two basal joints stouter than the terminal, which is slender 

 and subfusiform ; maxillary minute : maxillee moderate, clothed externally 

 with long hairs nearly to the middle. Antennw contiguous, porrected, very 

 long, especially in the males, in which sex some of the basal joints are short 

 and hairy ; thickened only in the female : head small, pilose : eyes very large 

 in the males, approximating on the crown ; smaller in the females, and the 

 pubescence on the forehead pale in that sex : thorax sometimes hairy : wings 

 deflexed ; anterior lanceolate, frequently metallic ; cilia moderate ; posterior 

 ovate-lanceolate ; cilia rather long : body short and slender in the males ; 

 rather elongate and attenuated to the apex in the females. 



The great length of the antennas and the large approximatmg eyes 

 of the male insects of this genus at once distinguish them from their 

 allies, and the females may be known also by the length of the 

 antennae, and their slender attenuated body, exclusively of their 

 pilose head and palpi, generally uniformly coloured metallic wings, 

 &c. : the species fly in groups in the sun-shine, having the habits of 

 Tipulae or Ephemerae.
