reddish-brown stripe fades to a yellowish white, leaving the two lateral 

 ones as prominent dark streaks, widest on the central portion of the 

 frontal disk. 



Measurements : Length of body, male, 18 mm.; female, 20.5 mm.; of 

 tegtnina, male, 21 mm.; female, 25 mm.; of pronotum, male and female, 

 4.75 mm.; of hind femora, male, 16 mm.; female, 17 mm.; of ovipositor, 

 10 mm. Described from two males and four females. 



This species, the female of which is at once conspicuous by reason of 

 the shape and size of its ovipositor; has been taken in small numbers only 

 in Vigo county,* where it is found during August and September on the 

 leaves and stems of a tall, broaddeaved knot weed, Polygonum amphibium, 

 L., which grows luxuriantly in the shallow waters about the margins of 

 two or three large ponds in the Wabash River bottoms. Several other 

 "green grasshoppers," notably among which are Xiphidium altenuatum, 

 Scudder, and Orchelimum nigripes, Scudder, frequent this plant in immense 

 numbers. Keeping company with them an occasional specimen of 0. 

 brilneri is seen, but, being an active leaper.it often escapes amidst the 

 dense foliage of the knot weed before its capture can be effected. Its less 

 robust body and longer, armed posterior femora will readily distinguish 

 this species from 0. gladiator, the only other one which, to my knowledge, 

 has an ovipositor shaped like that of briineri. The latter is named in 

 honor of Prof. Lawrence Bruner, of Lincoln, Neb., one of the leading 

 authorities on N. A. Orthoptera.

The Indiana members of this subfamily comprise those insects which 

 are commonly called " stone" or " camel crickets," and, eo far as known, 

 belong to the single genus Ceuthophilus, which is characterized below. 

 VIII. Ceuthophilus, Scudder (1862). 



Wingless Locustidae of medium or large size with a thick body and arched 

 back. Head large and oval, bent downwards and backwards between the 

 front legs. Antenna- long, slender, cylindrical and tapering to a fine point. 

 Lyes sub-pyriform, the narrow end downwards, placed close to the basal 

 joint of the antenna. Maxillary palpi long and slender ; the apical joint 

 longest, somewhat curved, split on the under side three-fourths of its 

 length, which is nearly equal to that of the two preceding taken together. 

 Pronotum short, not extending over the meso and meta-notum. Prostern- 



-Since the above was written this insect has been found to be very plentiful about 

 the margin of Lost Lake, Marshall county, Ind.
