This species should be referred to the present genus, if Lord 

 Walsinghams determination of my specimen is authentic, as I 

 beUeve. It has sHghtly raised, smooth scale tufts on the fore 

 wings and veins 7 and 8 connate to costa; hind wings with 3 and

 in the insectary of the U. S- Department of Agriculture from galls 

 on oak, made by Olliffiella cristicoUe Cockerell, received from

 Pergande's note on the larva: "Preying on the Coccid. Head 

 "brick red, body purphsh, cervical plate paler anteriorly with a 

 "broad black posterior margin; body marked each side with a
