130 THE CANADIAN ENTOMOLOGIST. 



white scaling of the venter, and on most of the segments extend the whole 

 length. 



Legs : coxje and trochanters ligiit, and white-scaled ; femora white 

 Ventraily, s))eckled black and white dorsaliy, a narrow black ring just 

 proximal to the tiny white knee spot ; fore and mid tibite white ventrally 

 (on the hind legs this is reduced to a white line), speckled dorsaliy, a little 

 darker near the apex, but the apex light, and in the hind legs there is a 

 distinct dark band and light apex as on the femora ; metatarsi speckled, 

 those of the fore legs having light apices, of the hind legs having both 

 slightly lighter bases and light apices. On the fore legs the first tarsal 

 joints are black, with basal light bands, all the other joints dark ; on the 

 mid leg the first and second joints are still a little speckled, and have 

 white basal bands and tiny white apical spots, sometimes unhanded, third 

 and fourth joints dark ; on the hind legs the first and second joints are 

 dark (black), with basal and apical light bands, the third has a basal light 

 band, and the fourth is light ; all ungues equal and uniserrate. 



Wings clear, speckled with black and white scales, the costa being 

 mostly black, and the sixth long vein white, first submarginal a little longer 

 and more narrow than the second posterior cell, the petiole in each case 

 about half as long as the cell ; mid cross-vein twice as long as the 

 "supernumerary," and equal to the posterior cross-vein, which is about its 

 own length distant ; halteres, light stem and dark knobs. 



The leg banding involves both sides of most of the joints, and in this 

 greatly resembles G. Currici, the thoracic marking suggests G. lativitatta, 

 but the abdominal marking is clear, in some cases being only clean-cut 

 lines, in others a little ragged. The types do not, however, suggest either 

 species more than to indicate their close relationship, having a peculiarly 

 tidy appearance which the others lack.
