Female.— Head (cephalic aspect) rounded, slightly wider than long, the 

 face subquadrate and broad, concave, the eyes over half the length of the 

 cheeks, the face on each side with a narrow sulcus running from vertex to 

 clypeui along the inner (mesal) margins of the eyes and continued (dorsal 

 aspect) caudad around tlie mesal eye margins, then laterad and ventro- 

 cephalad following around the outer (lateral) eye margins ; the sulci of each 

 side are joined by a similar but transverse sulcus across the cephalic margin 

 of the vertex or just preceding that margin. Apical (ventral) margin of 

 clypeus regularly concave, entire ; clypeal sutures obsolete. Lateral aspect 

 of head elliptical ovate in outline, the eyes ovate; scapes of the antenna 

 projecting above (dorsad) the line of the vertex. Vertex wide between the 

 eyes, rectangular, widening caudad, sloping gently cephalad ; a fourth wider 

 than long, its cephalic m.argin subacute, straight, its caudal margin slightly 

 concave, subobtuse ; plane of the vertex somewhat convex caudad, the three 

 ocelli in a flatly curved line across the caudal third, the lateral ocelli not 

 touching the eye margins; head distinctly wider than the greatest width 

 of the thorax, non-punctate, finely lined. Antennae inserted somewhat above 

 (dorsad) the middle of the face, five-eighths the distance up the eye mar- 

 gins, hence distinctly dorsad of an imaginary line drawn between the ventral 

 ends of the eyes, their bulbs widely separated, near the eye margins, at least 

 three times further from each other than each is from the respective eye 

 margin, lo-jointed, capitate, the funicle filiform, the club 2-jointed, ovate and
