of the femora that I have more than once been inclined to think them a 

 distinct and undescribed species. They have the middle femora armed 

 beneath with 3 spines on each carina; the hind femora of male with 9 

 spines on the outer carina, the 4 or 5 middle ones of which are very 

 strong and prominent, the inner carina with 11 small and sub-equal spines. 

 The hind tibise with an evident downward curve at base. The hind femo- 

 ra of the female have 5 small spines on the outer and 11 on the inner car- 

 ina. 



Measurements: Male — Length of body, 22 mm.; of pronotum, 6.5 

 mm.; of front femora, 9 mm.; hind femora, 19 mm.; of hind tibise, 21 

 mm. Female — Length of body, 25 mm. ; of pronotum, 7 mm. ; of front 

 temora, 9 mm. ; of hind femora, 19.5 mm. ; of hind tibia% 20.5 mm. ; of 

 ovipositor, 13 mm. 



If, as is most likely, these are only greatly developed forms of latens, the 

 spining of the femora of these insects varies greatly with the age, and, 

 unless one has adult specimens, it is not therefore a character of as much 

 specific worth as is usually attributed to it. 



( '. latens is not an uncommon species in Vigo and Putnam counties. It 

 is most commonly found beneath flat stones near the margins of small 

 streams in upland, hilly localities. It reaches maturity in June or July, 

 probably from specimens hatched in spring, though I have taken the 

 young on two different occasions in February. It has been recorded here- 

 tofore only from Illinois and the male is herewith described f'Cr the first 

 time, Mr. Scudder's description having been based upon a single female. 



cc. Sides of body without a dark, reddish brown stripe. 



d. Hind femora of male with the inferior sulcus very deep ; the 

 outer carina with about 9 spines of unequal length and not 

 equi-distant.
