158 MANDIBULATA. TRICHOPTEEA, 



Genus VI.— BERi3^:A mihi. 



Antennce rather slender, shorter than the wings, porrected, the basal joint 

 robust, elongate and hairy: maxiUarj palpi long, stout and hairy : labial 

 short : head small, transverse, pilose in front : thorax ovate : wings short, 

 vrith very indistinct nervures ; anterior broadish, rounded at the apex ; all 

 very pubescent, and fringed with long hairs : abdomen short, obtuse : legs 

 rather short : tibice all with a pair of longish spurs at the apex, the posterior 

 pair with a smaller pair below the middle. 



The little insects comprised in this genus differ from the rest of 

 the family by having the palpi robust and hairy, the basal joint of 

 the antennae stout, directed forwards, and also very hairy, the antennae 

 themselves being rather slender, especially at the tip ; the wings are 

 rather broad, short and rounded at the apex, with^very indistinct 

 nervures, and very hairy ; they are generally of very sombre dark 

 hues, and the insects of small size : the genus corresponds with Thya 

 of Curtis, but as that name was long since employed by Dr. Leach 

 for a genus of Crustacea, I shall adopt the one given previously to 

 Mr. Curtis's, in the second edition of my Nomenclature.
