bana, Illinois, in sweepings, two males. May 25, 1910, on

There is a color variety of this species, at first thought to 

 be distinct from it but since considered the same, as both 

 forms agree structurally ; this variety agrees with aureus in 

 color. It is described herewith. 

 Govatocerus brunneus toiiiipennis varietas nova. 



Normal position. 



Female. — Length, 0.65 mm. Moderately small for the genus. 



The same as brunneus , differing in being somewhat lighter in color, 

 the thorax, head and base of the abdomen pale cadmium yellow, the 

 rest of the abdomen dusky brown, in being smaller in size and primarily 

 in having somewhat more slender fore wings ; the antennae are olive 

 greenish and differ from those of brunneus in not having the sixth 

 funicle joint quite so distinctly shorter than the joint immediately pre- 

 ceding and following it. Its legs are uniformly concolorous with the 

 body or a shade lighter. The marginal cilia of the fore wings are 

 equal to a third of the greatest width of those wings. The posterior 

 wings are very narrow, and bear no discal ciliation in the midlongi- 

 tudinal line. 



Antennae like those of brunneus ; funicle joints 5, 6 and 7 subequal, 

 nearly equal to the pedicel in length, twice the size of 3 or 4, 8 a fourth 

 shorter. The club large, ovate, abdomen short, triangular. 



From 2 females, f-inch objective, 1-inch optic, Bausch and 

 Lomb. 



Male. — Unknown.
