152 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



It is evident that the individual variability in this insect is 

 great and as it is as yet known typical from only five localities 

 in a small area in central southwestern Oregon its racial validity 

 may yet not be considered unequivocally established.

Fulton reduced calapooyae to racial status in 1930, but placed 

 it as a race of validus. In 1899 Scudder incorrectly recorded 

 material of this race from Divide, Drain and Roseburg in the 

 series described as validus, while in 1930 Fulton also recorded 

 males from Roseburg and Canyonville as validus. 



The present race is distinguished by the very much larger distal 

 triangular expansion of the male cerci. The penis also has the 

 cochleation of the dorsal lobes more ample and these are rotated 

 caudad so that their concave surfaces surround the vertical acute 

 apices of the ectoparameres from behind instead of from between 

 them, thus giving a very different appearance. Close agreement 

 in this feature alone is shown by two of the three males from 

 Crabtree, Oregon, here discussed under saltator.

 $. Drain, 6$, 2$. Roseburg, 1$, 12. Woodruff Meadows, $$, 2$, 

 (slightly atypical, the male cerci less triangular distad and thus showing 

 definite divergence toward ascensus ascensus). 



The caudal tibiae of the males are buffy, sometimes with a 

 weak glaucous or pink tinge, of the females rich pink, but in the 

 atypic Woodruff Meadow series they are coral red in both sexes. 

 Though marked as in the other races, the caudal femora exter- 

 nally usually show only moderate color contrasts with the paler 

 areas extensive and confluent. 



This race evidently occupies the area between the southern 

 limits of saltator and the northern limits of ascensus validus, the 

 series from Woodruff Meadows to the east atypic toward ascen- 

 sus ascensus.
