ORTHOPTEKA OF INDIANA. 395 



Color: Male — Usually a dark sooty brown flecked every where with 

 grayish; the apical third of hind femora lighter; the yellow line on 

 lower border of pronotmn indistinct or Avanting. Female — Dull, yel- 

 lowish brown; the posterior lobe of pronotum, dorsum of abdomen 

 and ovipositor dark brown. A blackish spot on the fa-ce below each 

 eye; the sides of the pronotum with obsolete fuscous markings. 



The chief structural distinctions between this insect and paclitj- 

 mervs are given above in the key and under the latter species. It 

 may be added that the hind lobe of the pronotum in dorsalis is quite 

 short and has its posterior margin nearly truncate; whereas in 

 pacilii/merus it is much longer with the hind margin broadly rounded. 



Measurements: Male — Length of body, 19 mm.; of pronotum, 9 

 mm.; of hind femora, 19 mm. Female — Length of body, 24 mm.; 

 of pronotum, 9.5 mm.; of hind femora, 20.5 mm.; of ovipositor, 

 23 mm. 



Doj'salis has been taken in the State in Putnam, Vigo, Knox and 

 Crawford counties. In the two last named counties it is more com- 

 mon than the other species. Its general range is more southern and 

 it will probably be found to inhabit only the southern half of In- 

 diana. 



Sub-family GRYLLACRIN.E. 



This sub-family is represented in the State by the single genus, 



XLIX. Camptonotus Uhler (1864). 



Form similar to Ceufliopliihis Scudd. Head large, oval, much 

 broader than the prothorax and not deeply sunken into it. Eyes 

 ovate, vertical, situated on the sides but little behind the basal joint 

 of the antenna?, and exceeding it a little in length. Maxillary palpi 

 long, the last joint as long as the preceding one, a very little inflated 

 at the tip. Antenna? at least five times the length of the body with- 

 out the ovipositor. Pronotum trapezoidal, the sides not carried 

 downwards as far as the lower line of the eyes, the lateral margins 

 somewhat broadly recurved; mcso- and meta-notum very small, con- 

 fined to the dorsum and not prolonged downward upon their sides. 

 Ovipositor ensiform, curved upwards, its valves conijn'essed, acute. 

 Legs very short, moderately stout; the anterior and middle tibia? 

 slightly incurved near the base, liaving a row of four long spines 

 each side beneath; posterior femora armed beneath with a few short 

 teeth. Tarsi stout, four-joinled, witli split cushions beneath, the 

 first joint equal in length to the two following ones conjoined. 



A single species is known from the eastern United States.
