190 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



shining blackish brown areas and often with a buff fleck dorso-cephalad of 

 these. Tegmina unicolorous or sometimes with veins slightly paler than 

 the ground coloration. Abdomen often definitely paler, more buffy, but 

 never showing a medio-longitudinal dorsal pale band. Cephalic and median 

 limbs buffy brown, caudal femora externally similar or somewhat paler but 

 with genicular areas and margins of external pagina (this usually weaker on 

 ventral margin of that area) blackish brown. Internal and ventral surfaces 

 of caudal femora, ventral surface of body and caudal tibiae yellow buff 

 (probably usually clear light yellow in life in the two latter areas), spines 

 and spurs black. 



Females are even more uniform in coloration and usually darker, with a 

 short dorso-cephalic oblique buffy line on pronotal lateral lobes alone more 

 conspicuously developed, the other paler brown areas usually generally 

 darkened. 



Length of body $ 16.6 to 18.4, $ 20.1 to 23.7; length of pronotum $ 3.7 

 to 4., $ 4.4 to 4.7; caudal width of pronotal disk S 2.3 to 2.7, $ 3.8 to 4.3; 

 length of tegmen S 2.7 to 2.8, $ 3.1 to 3.8; length of caudal femur $ 8.3 to 

 9.2, $ 10.2 to 10.8 mm. 



A series of twenty-nine males and eleven females, paratypes, 

 bear the same data as the described pair. These were found in 

 the open forest of Sugar Pine, in chaparral mainly composed of 

 Manzanita and Purshia tridentata (Pursh) but particularly in 

 areas carpeted with a low chinquapin ; very scarce on the south 

 slopes but common on the summit of Harkness Peak, which is 

 an extinct volcanic cone not distant from Mount Lassen. Males 

 were found to leap quite vigorously but rarely attempted hiding 

 down in the bushes and so were easier to capture than such 

 thamnophilous insects as Aeoloplus, which are adepts at hiding 

 as well as at leaping. The females were more difficult to locate, 

 but were very sluggish and clumsy and consequently easy to 

 capture when once seen.
