This insect has a wide range, having been recorded from New England 

 to the Kocky Mountains. In Indiana it is, as far as my observation goes, 

 much less common than some of the other species of the genus, having so 

 far been taken only in Putnam county where, on August 1st, I took sev- 

 eral specimens from beneath a log in a deep and damp ravine. It probably 

 occurs sparingly in like situations throughout the state. 



aa. Hind tibia? of male not undulated at base ; sometimes with a single, 

 slight curve. 

 b. Hind femora but little, if any, shorter than the corresponding tibia 1 ; 

 species living above ground. 

 c. Upper sides of body each with a broad, dark reddish-brow r n stripe.

General color, light, reddish brown "with darker streaks upon the 

 hind femora and two broad bands of dark, reddish brown along the whole 

 dorsum, extending half way down the sides, dotted irregularly with brown- 

 ish yellow spots, most profusely on the abdomen, and separated from one 

 anuther by a narrow, irregular band of the same color; below yellowish 

 brown ; tips of the hind femora dark." 



Anterior tibia? one-third longer than the pronotum, with two spines on 

 the outer lower carina. Middle femora bispined on each carina beneath. 

 Hind femora thick and stout, the inferior sulcus wide and deep, the mar- 

 gins unarmed in the female; in the male with three or four minute spines 

 on the apical third of each carina. Hind tibiae straight, a little longer 

 than the femora. 



Measurements : Male — Length of body, 18 mm. ; of pronotum, 5 mm.; 

 of front femora, 6.5 mm. ; of hind femora, 14 mm. ; of hind tibife, 14.5 

 mm. Female — Length of body, 19 mm. ; of hind femora, 14.5 mm. ; of 

 hind tibia?, 15 mm. ; of ovipositor, 10 mm. 



The above description applies to the species as usually found in the 

 State. I have, however, a pair of specimens taken in Putnam county, 

 which, while agreeing fully with the peculiar coloration and relative 

 measurements of latens, differ so markedly in size and in the spination
