Black and slightly pilose : antennffi dusky-black ; wings brown-black, imma- 

 culate, anterior with a griseous tinge ; legs pale ochreous.

 deep black. 



, Rather common, in the neighbourhood of Hertford, in June and 

 July. 



Genus XXII.— GOERA, Hofmansegg. 



Antennce longer than the wings, the basal joint stout, long and pubescent, 

 parallel, the remainder very small, much attenxiated at the apex: palpi 

 pubescent; maxillary in the males recurved, and slightly clavate; of the 

 females slender: head rather small, pilose : eyes somewhat prominent: wings 

 rather broad, rounded at the apex, obtusely-lanceolate ; nervures not very 

 distinct, two on the costa, then three furcate ones, followed by a curved one 

 towards the posterior angle, which forms a dilated somewhat circular areola*' 

 towards the apex of the inner margin ; posterior wings small, slightly folded 

 within : legs rather short : tibia all with a pair of spurs at the tip, the two 

 hinder pair with another pair below the middle. 



As previously mentioned, these insects have the basal joint of the 

 antennse porrected, elongate and robust, and the two are parallel 

 "with each other ; the males are distinguished by having short 

 maxillary palpi, which are recurved and closely applied to the head ; 

 those of the female are long and slender ; the wings have a very 

 silken appearance, and have a conspicuous dilated and orbicular 

 areolet towards the apex of the inner margin.
