150 ORTHOPTEEA OF MAINE. 



peg, and the Island of Anticosti. The species looks very much like Caloptenus 

 jemur-rubrum, except in the length of the wings and wing-covers. 



yertex of the head with a broad and shallow sulcation in front of the middle 

 of the eyes, broadest between the lateral ocelli ; frontal ridge with a lengthened 

 oval depression about the central ocellus; eyes elongated, rather large; an- 

 tennas slender, about equal to the length of the head and thorax ; sides of 

 the pronotum slightly divergent posteriorly, margin in front straight, behind 

 arcuate ; lateral carinas indistinct, medium very slight for its anterior half, 

 but quite prominent posteriorly ; posterior margin of the side of the prono- 

 tum not oblique, very similar in form to that of Caloptenus femur-rubrum 

 Burm. ; sternal spine prominent, rounded at the point ; wing-covers longer 

 than the wings, reaching about three-fourths of the length of the abdomen, 

 overlapping slightly upon the back, costal border much swollen toward the 

 base, internal border full ; wings short, costal border nearly straight, outer 

 border full and rounded ; hind femora above with square lateral carinas, and a 

 high sharp median carina ; abdomen with a distinct median carina. 



Head above, dorsum of the thorax, and wing-covers dark brown, mottled 

 with lighter ; sides of the pronotum smooth and shining in front of the pos- 

 terior transverse impression, behind it thickly punctate ; a broad black band 

 extending from the eye over the upper half of the pronotum, indistinct 

 posteriorly ; front of the head and sides of the pronotum below the black 

 band, dirty yellow ; an oblique yellowish stripe upon the sides of the thorax 

 as in the last species ; antennas reddish brown ; fore and middle legs dark 

 brown, greenish yellow upon the under side of the femora ; hind femora red- 

 dish below, banded and streaked above with black, apex black ; hind tibias 

 reddish, with a black annulation near the base, the spines tipped with black ; 

 wings almost colorless, very faintly tinged with yellow at the base, a little 

 dusky along the costal border. 



Length .82 in. ; length of wing-covers .38 in. ; breadth of wing-covers 

 .12 in. ; length of wing .30 in. ; length of hind femora .45 in. ; 1 female. 



Speckled Mountain, Stoneham, August 15, 1865. 



The species mentioned by Dr. Packard, in his Report on the Insects collect- 

 ed on the Penobscot and Allegush Rivers, published in the Report of the 

 Scientific Survey of Maine for 1861, is probably a Pezotettix, perhaps a P. 

 borealis.
