forward, divides the black of the front of the head. Eyes 

 surrounded by yellow, a black spot caps the hind angles of 

 the head. Antennae fuscous ; palpi pale ; tubercles angu- 

 lar, subcarinate, obscure, black. 



Prothorax nearly twice as wide as long, brown with yel- 

 low mid-dorsal stripe that widens to its ends. Embossed 

 markings in the brown of the disc coarse and obscure; 

 sides parallel. Legs brown. Fore wings and costal strip 

 of hind wings brownish with darker veins. 



Abdomen pale above, fuscous at sides and beneath. 



Male. Pale above and below with brown sides, the pale 

 color of the dorsum cut obliquely at sides and extended 

 downward farthest at apex of each segment. Segments 

 normal to the 8th which is a little enlarged ventrally, and 

 bears across its mid-ventral apical margin a long, bow- 

 shaped or slightly crescentric callosity in the middle line 

 of which is a small rounded lobelike projection. Segment 

 9 is very much enlarged and prolonged ventrally into an 

 ovate broadly rounded subgenital scoop that doubles the 

 length of the segment and includes segment 10 and the 

 genitalia. Scoop yellow, washed with brown at sides 

 basally. 



Female. The subgenital plate is scarcely modified from 

 the straight cut sternite of the 8th abdominal segment 

 being set off by obscure folds, its edge but little elongated 

 and outcurving and not strongly chitinized. The yellow 

 of the under surface of segments 9 and 10 is invaded mid- 

 laterally by the brown of the sides and there are paired 

 isolated touches of brown on the sides of the preceding 

 segments.
