In this species the tegmina are found to overlap slightly in the majority 

 of specimens, they are attingent in some and are separated by a slight to a 

 moderate interspace (maximum 1.2 mm.) in a few individuals, particularly 

 among the females. The tegminal size is decidedly variable; in the great 

 majority of specimens they are broadly lanceolate, in rare examples broadly 

 oval. 



The furcula are normally so little developed in this species that we are not 

 surprised to find frequent males entirely lacking these processes. 



Coloration. — Type. Head orange-cinnamon, vertex deep russet, post- 

 ocular blackish bars not wide and narrowly margined dorsad with buffy. 

 Pronotum with disk russet, deepening to mars brown laterad, lateral lobes 

 buffy suffused with tawny, except for an irregular shining blackish brown bar 

 dorsad which deepens caudad, terminated at the principal sulcus and there 

 occupying two-fifths the depth of the lateral lobe; metazonal portion 

 deepens to mars brown dorsad. Tegmina mars brown with a very 

 few darker flecks. Abdomen ochraceous-tawny heavily suffused with black- 

 ish proximo-laterad, a small area before bases of cerci on eighth tergite and 

 tips of cerci blackish. Cephalic and median limbs tawny, slightly suffused. 

 Caudal femora tawny with the trivittate marking, characteristic of many of 

 the Melanopli, showing in blackish brown, but much blurred; ventral sur- 

 face tawny. Ventral surface of insect and caudal tibiae cinnamon-buff, the 

 spines of the latter black tipped. 



In the female sex the coloration is similar, usually of a somewhat less red- 

 dish tone, the markings of the caudal femora not as dark and the caudal 

 tibiae coral pink. 



In the maximum recessive coloration the insects are ochraceous-tawny, 

 the tegmina slightly darker, the postocular bars and other darker markings 

 obsolete. 



It is of interest to note that males or females of at least some of the species 

 of this group may show pink or bluish caudal tibiae. 



Specimens Examined: 149; 79 males, 69 females and 1 immature indivi- 

 dual.

 allotype and paratypes; IX, 12, 1897, (A. P. Morse), 1 9, paratype of M.

At Divide the species was generally distributed and very com- 

 mon both in the grassy valley and on hillsides covered with a 

 scattering growth of scrub oaks. At an elevation of 800 feet, 

 however, it was particularly plentiful in a brule, among dead 

 pine boughs and tops. At Drain it was rare on hillsides of short, 

 dry, yellow grass.
