the sixth line at about the latter's distal third, but reaches the caudal 

 wing margin near its distal end at a point nearly opposite to the apex 

 of the second row of cilia; the sixth or last, most caudal row is sub- 

 acutely convexed at its middle and forms the caudal boundary of the 

 proximal projection of the discal ciliation ; it originates proximad near, 

 but not touching, the caudal wing margin and proceeds distad in the 

 form of a flat pyramid with a long (imaginary) base, ending in the 

 caudal wing margin at about the base of the distal third of the wing. 

 Of these six peculiarly regular lines, the third and fourth are longest. 

 Lateral ocelli twice farther apart from each other than each is distant 

 from the respective eye margins and slightly farther apart than each 

 is distant from the cephalic ocellus ; over their own width from the 

 eye margins. 



Antenna clavate, with normal pubescence, sparse, long and soft 

 setae increasing in number on the club. Scape moderately short, 

 cylindrical, longer than the funicle but slightly shorter than the club ; 

 pedicel obconic, shortest of the segmental regions, a fourth shorter than 

 the tunicle and nearly a half shorter than the scape ; funicle much 

 wider, broad, oval and as wide as the middle of ttie club, which is 

 conic-ovate, forming over half of the flagellum, its two proximal joints 

 complementary, the intermediate joint obliquely truncate at both ends, 

 the apical joint pointed conic and slightly shorter ; club divisions 

 oblique. Ring-joint very short, with rimmed margins, saucer-shaped, 

 apparently concealed within the hollow base of the funicle joint.

 and Lomb. 



Male. — The same ; antennae entirely different, clothed with whorls 

 of long hairs, cylindrical, the joints all equal and in the single speci- 

 men the terminal joint apparently inclosing a minute, globular eighth 

 joint at its extreme apex like a ball in a socket. The ring-joint ap- 

 parently absent, hence four funicle joints. 



From a single specimen, s-inch objective, 1-inch optic, 

 Bausch and Lomb. 



Described from 1 male and 18 female specimens mounted 

 in balsam, the coloration and sculpture from two living 

 females, unmounted, stupefied with chloroform and taken at 

 Centralia, Illinois, September 5, 1909 and from two females 

 in the U. S. National Museum. The following slides : (1) 

 A slide bearing one female labelled " On window, Centralia, 

 Illinois, September 5, 1909 (A. A. G.);" and (2), (3), (4),
