'eight to ten setigerous punctures ; the head of this appendage 

 is dilated into a roughly semicircular blade, the proximal 

 angle or "toe'" of which bears two strong setae, the apex one 

 large and one small seta, the lateral angle or "heel" of the 

 tlade a single powerful seta. At the base of this appendage 

 at the caudal lateral angle of the pleurite is a small, cylindri- 

 cal, setiferous lobe and a short chitinized horn. The third 

 appendage is the longest and is fused basally with the dorsal 

 appendage, deeply constricted beyond the base, more slender 

 than in Uorcns, gradually narrowed to the short but powerful 

 .apical spine. The second appendage appears as an elongate, 

 ;sinuous, chitinized blade that is constricted at near two-thirds 

 to three- fourths its length, beyond this point tapering into a 

 long, sickle-shaped blade; in Horens this appendage is stouter, 

 not sinuous, the apex not produced into a blade. Gonapophyses 

 appearing as two long, chitinized spikes, directed dorsad, these 

 much larger and more powerful than in Horens. 



Holotype, male, swept from beds of Dianthera in Little 

 Indian Creek, Corydon, Harrison County, Indiana, June 18, 

 1921 (Alexander). 



Paratopotypes, 3 males (Alexander and Rogers). 



Teucholabis complexa immaculata, subsp. n. 



Very similar in all respects to T. complexa O. S., differing 

 as follows : 



Mesonotum shiny reddish, unmarked with darker. Pleura 

 obscure yellow, the dorsal brown stripe in complexa repre- 

 sented only by a large rounded spot cephalad of the wing-root. 

 Brown femoral tips broader and more gradually darkened. 



Abdomen lighter colored; sixth sternite with a large 

 rounded black spot; seventh sternite with two smaller black 

 spots.
