fig. 9 and 10. The Wingless Mountain Grasshopper. 



Speckled Mountain in Stoneham, August 15, 1865. Ten specimens were 

 taken at different points about the summit of the mountain. 



This species was discovered in the subalpine district of the White Mountains 

 of New Hampshire by Mr. Scudder, and described by him in 1863, in a paper 

 on the Insect-Fauna of the White Mountains. Mr. Scudder has since taken it 

 upon Gray Lock, in Berkshire County, Mass., and Mr. Sanborn of Boston in- 

 forms me that he has taken it about the Umbagog Lakes in northwestern 

 Maine. It is the only described species of the genus hitherto known in New 

 England. , 



The mountain, upon which this and the two following species were taken, 

 one of the many Speckled Mountains in the state, is in the southwestern part 

 of Oxford County, and properly belongs to the White Mountain group. I am 

 not aware that its height has ever been determined, but it is probably much 

 above two thousand feet. Upon the upper and treeless part of the mountain, 

 where all the species of Pezotettix occurred, the following plants were abund- 

 ant: Alsine Grcenlandica Fenzl., Potentilla tridentata Ait., Vaccinium Vitis-Idaa 

 L., V. uliginosum L., Empetrum nigrum L. 



Pezotettix manca sp. nov. 



Vertex of the head with a sulcation, narrow between the middle of the 

 eyes, but broader anteriorly, and in the female but little depressed ; frontal 

 ridge with a shallow sulcation, and a sudden depression at the central ocellus ; 

 eyes very little elongated, slightly prominent in the male, not so much so in 

 the female ; antennas, in the female, slender, not quite equaling the length of 

 the head and thorax; sides of the pronotum slightly divergent posteriorly, 

 margin in front straight, behind a little arcuate ; lateral carinas indistinct, 

 median slight but distinct ; posterior margin of the sides of the pronotum very 

 oblique, and the lower posterior angle rounded ; sternal spine prominent, 

 blunt ; wing-covers very small, oval, extending to the middle of the first ab- 

 dominal segment, not meeting upon the back; no wings upon the metanotum ; 

 hind femora with square lateral carina above, and a sharp median carina below, 

 the double internal lateral carinas sharp and prominent ; abdomen with a well . 



marked median caring extending distinctly on to the meso- and metathorax. < ^/ 



Head above, dorsum of the thorax, and wing-covers, brown ; sides of the / 

 pronotum smooth and shining in front of the posterior transverse impressions, 

 behind it thickly punctate ; a broad black band extending from the eye over 

 the upper half of the pronotum on to the remaining thorasic segments and 

 along the side of the abdomen, inclosing upon the thorax, an oblique whitish 

 stripe which extends from near the base of the wing-cover to the base of the 

 hind femur ; antennas reddish brown, darker at the tips ; fore and middle legs 

 dark brown, greenish yellow on the under side of the femora ; hind femora 

 brown, yellow below, banded with black above, apex black ; tibias bright red, 

 spines tipped with black. 



From dry specimens. The male and the female do not seem to differ in 

 coloration. 



Length, male, .65 in., female, .81 in. ; length of wing-covers, male, .16 in., 

 female. .17 in.; breadth of wing-covers, male, .09 in., female, .11 in.; length of 

 hind femora, male, .35 in., female, .42 in., 1 male, 1 female. 



Speckled Mountain, Stoneham, August 15, 1865. 



Pezotettix borealis/ Scudd., 1. c, p. 464. 



I have a single specimen of another species, which agrees well with the 

 description of P. borealis Scudd., and, although a hasty comparison with the 

 original specimens in Mr. Scudder's collection, shew some very slight differ- 

 ences, I do not think it will prove to be distinct from that species. Mr. 

 Scudder's specimens were from Minnesota, Saskatchewan River, Lake Winni-
