EvunicUa semaeoda Bradley, Trans. Amer. Ent. Soc, vol. 34, p. 144, 1908. 

 Type: $, Browns Mills, N. J. (Ithaca). 



Forewing about 4.8 mm. long; head about 1.0 as wide as the thorax ; 

 cheek about 0.3 as long as the height of the eye; mandible without 

 a posterior ventral tooth ; frons and temple with close large punctures; 

 mesoscutum with numerous large punctures, closely spaced on the 

 median lobe and sparse on the lateral lobes; shoulder carina of 

 pronotum strong, continuous across the midline and laterally curved 

 backward to near the hind margin of the pronotum below the tegula; 

 subdiscoidal vein weak, unpigmented; first tergite with very fine 

 punctures, in the female with very sparse, large punctures also. 



The color varies from nearly all black to nearly all but the gaster 

 ferruginous. Blackish specimens have the legs a little paler than the 

 body ; tegula and front tibia and tarsus ferruginous ; scape and front 

 femur brownish ferruginous; basal part of first trochanter of hind 

 legs stramineous; and basal four segments of female antenna stra- 

 mineous to brownish ferruginous. Commonly the pronotum and meso- 

 scutum are ferruginous and the apical part of the first tergite stra- 

 mineous. In the most extensively ferruginous specimens only the gaster 

 is blackish, and the flagellum of the male and all but the basal three 

 flagellar segments of the female dark brown. The head and hind legs 

 are among the last parts to be invaded by ferruginous.
