dark brown transverse band at base; as long as broad, trapezoidal 

 broadly truncate at apex; truncation about one-third breadth at 

 spiracles. Mandibles broadly rounded with acute outwardly curved 

 tooth at inner apex. Mouth broadly rounded, subquadrate. Spira-

8. STYLOPS BIPUNCTATjE, new species. 



Host. — Andrena bipunctata Cresson; Indiana, collected by C. F. 

 Baker. Described from one specimen from the Carl F. Baker collec- 

 tion of the U. S. National Museum. 



Female. — Length of cephalothorax 0.78 mm., breadth at spiracles 

 0.75 mm., breadth at base of head 0.45 mm., distance between man- 

 dibles at base 0.16 mm. Cephalothorax light yellowish brown with 

 narrow dark transverse band at base; slightly longer than broad, 

 deltoid, broadly truncate at apex; truncation about one-third breadth 

 at spiracles. Head slightly constricted laterally at base of mandi- 

 bles. Mandibles oblique, broadly rounded with acute outwardly 

 curved tooth at apex, and a second tooth about middle of outer side 

 below. Mouth almost round. Spiracles dorsal, not reaching lateral 

 edge. 



Paratypes with the following records were also studied : Polk County, 

 Wisconsin, C. F. Baker; Alabama, C. F. Baker; Sioux County, 

 Nebraska, May, L. Bruner; Milwaukee, Wisconsin, April 17, 1902, 

 S. Graenicher. The outer tooth of the mandibles is not as distinct 

 in these as in the type.
